The hydraulic system is built as a central hydraulic main ring line system in closedloop where hydraulic pumps deliver oil to a main pressure line. From this mainpressure line a number of hydraulic motors can be run provided that a sufficientnumber of power packs have been started. In order not to overs peed the hydraulicmotors, a speed control valve is installed up stream of each motor.
The main hydraulic pumps are of axial piston type, swash plate design with variabledisplacement. The pump displacement (swivel angle) is hydraulically controlled viathe pressure regulator on each pump.
At start~up, the variable pump is in max. swivel angle, and a pressure is built up inthe pressure line. This pressure is internally bled off through the pressure regulatorand a solenoid valve, energised at start-up, causing that the swivel angle is reducecto min. After approximately 10 seconds for electric hydraulic power packs andapproximately 3 minutes for diesel hydraulic power packs, the solenoid valve isde-energised and pilot oil from the pump will push the swash plate to an increasedswivel angle, and oil is delivered into the main pressure line. However, if no oil isneeded, a pressure is built up in the main pressure line. When this pressure reachthe set pressure of the proportional valve, the valve will open for oil through thepressure regulator, and the swivel angle will decrease until a balance is reachedbetween oil delivery and oil consumption.
If the oil consumption from the cargo pumps is increased, the system pressure willdrop slightly, and the oil flow through the proportional valve will drop. Pilot oil fromthe pump will now push the swash plate to increased swivel angle until a newbalance is reached between oil delivery and consumption.
By this system the oil delivery from the hydraulic pumps will always be the same asthe oil consumption from the motors.
All cargo and other pumps connected to the system may be remotely controlled fro!Framo control panel, vessel computer or locally at each pump via the speed controlvalve STC (Speed Torque Controller). This valve is designed to control thedischarge from cargo- and other pumps powered by a central hydraulic ring linesystem.
The valve is set to a maximum oil flow, limiting the oil flow to the hydraulic motor anthus limiting the motor speed and consequently prevents overspeed. The oil flow isproportional to the speed, which can be steplessly regulated.For further information about the STC-valve, see separate instruction.
The portable pump speed is locally controlled at the pump.

One of the feed pumps on the auxiliary hydraulic unit (one in operation and one instand-by) circulates oil into the return/suction line and back to the unit, via the built-inlow pressure relief valve. The feed pump runs at full speed during operation of thehydraulic pumps, and half speed when the hydraulic pumps are stopped. At halfspeed, the feed pump keeps the hydraulic system pressurized at approximately6 bar to avoid possible cargo leakage into the hydraulic oil.
The main filter and the oil cooler with a built-in temperature controlled shut-off valvefor the cooling water, are installed in the main return line to keep the oil clean andthe temperature within desired range. The shut-off valve is installed by the Yard onthe cooling water inlet line, but controlled from the FM system control system.
For safe operation of the system, several transmitters/switches/alarms are installed.
HYDRAULIC FLUIDS, FLUID CLEANLINESS;
Hydraulic pumps, motors and controls are devices requiring close tolerances,controlled wear surfaces, accurate finish and an adequate supply of clean hydraulicfluid. Contaminated fluid will not provide proper lubrication and is a leadingcontributor to reduced efficiency, excessive downtime and increased maintenancecost.
Max. recommended water content is 300 PPM (0.03 %), and must under nocircumstances be above 500 PPM (0.05 %). If in doubt, please contact Framo.
Recommended cleanliness level is code 16/12 according to ISO 4406(or CETOP PR20). 16/12 means that number of particles:Above 5 micron in 100 ml is between 32000 and 64000.Above 15 micron in 100 ml is between 2000 and 4000.

System description (electrical)
GENERAL
The Framo cargo pumping system is controlled by a Programmable Logic Control(PLC) installed inside the control panel. The PLC is programmed by Framo andprovides the logic for safe operation of the system. Modifications of thesystem/program carried out by others may effect the warranty of the system.
This section should be read in conjunction with dedicated system drawings.
ALARM SYSTEM
The alarms are divided into two groups:
a)b)
Alarms and shut down of the hydraulic system.Alarms for indication (pre-warning) only.
All alarm inputs, except "excessive wear" are normally closed. This means that thesystem is built up on normally closed contacts. Hence if a contact opens or there is aloose wire, an alarm condition occurs, i.e. FAIL TO SAFE.
Each alarm is indicated with a flickering light and an acoustic signal until the"acknowledge" push button is activated. If the alarm condition still is on, the lamp willturn into a steady light and bu~er will stop
To clear group a) alarms, the "system reset" button must be activated before anypower pack can be restarted.Group b) alarms have got automatic reset.Please refer instrument list for applicable alarms and time delay.
FEED PUMPS
Start/stop of the feed pumps is performed manually from control panel, or from theelectric starter cabinet. However, when initiating start of the first main power pack,one of the feed pumps will automatically be started in high speed before the powerpack is started. When the power packs are stopped, the feed pump will switch fromhigh to low speed automatically after 10 minutes if this is not done by operator. Onlyone feed pump can run at the time. Interconnections are made to preventsimultaneous running. A running signal is provided for indication on the controlpanel.
The high speed mode is used to keep a feed pressure on the suction side of themain hydraulic pumps. One of the feed pumps must therefore be running in thismode before any of the main power packs can be started.

'-----
If the feed pump stops when running in high speed and the power packs arerunning, the second feed pump is started in high speed automatically. Ifthe runningsignal for the second feed pump is not obtained within3 seconds, the feed pressurelow alarm is initiated and the system willbe shut down.
The low speed mode is used to pressurize and deaerate the system to preventcargo leakage into the hydraulic system when the power packs are not running.One of the feed pumps must therefore always be running in this mode when thehydraulic system is not in operation.
Ifthe feed pump stops when running in low speed and the system is not inoperation, the return pressure lowalarm is initiated.
MAIN POWER PACKS '-Start/stop of the main power packs is performed manually from control panel, orfrom the electric starter cabinet.
The power packs can be started in any sequence. The hydraulic pump will bedisengaged for 10 seconds during start-up of electric hydraulic power pack and for3 minutes during start-up of diesel hydraulic power pack. The limit switches on thesuction line for each power pack will stop or prevent start of the correspondingpower pack only. An alarm light is provided for each power pack to indicate closedvalve.
If more than one power pack is loaded and the hydraulic oil temperature increasesto 65°C or above, the control system will automatically unload all power packs insequence except for one. The running light will start flashing for the unloaded powerpacks, and the high oil temperature alarm is re-initiated each time a new power packis unloaded. The power packs will automatically be reloaded in sequence when thehydraulic oil temperature has decreased below 60°C. ~
When activating the stop button for a diesel engine, the hydraulic pump willdisengage and the engine will run unloaded in 3 minutes for cooling purpose beforethe engine is stopped.
SYSTEM PRESSURE CONTROL
System pressure is set by means of the potentiometer at the front of the controlpanel, as a voltage input to the PLC. The PLC output is amplified by the proportionalvalve driver card to approximately 100 mA at minimum system pressure andapproximately 400 mA at maximum system pressure. The set pressure isautomatically set to zero until one of the power packs has been loaded.
The set pressure is compared to actual system pressure. If a pressure drop hasoccurred, the PLC is limiting output set pressure to maximum 40 bar above actualpressure. This is to assure smooth operation when starting/stopping power packsand consumers. This function is not active in manual override, mode 2.
The command signals from potentiometers at the front of the control panel are feddirectly into the proportional valves for speed control. The built in pressuretransmitters give a 4-20 mA (0-300 bar) feedback signal to the instruments on thecontrol panel.
COOLING WATER VALVE
The valve is automatically controlled and will receive "open" command at hydraulicoil temperatureabove50°C. It will stay open until the temperature decreases tobelow 30°C when "close" command is given.
If there is a mismatch between command- and feedback signal, an alarm will bereleased after 1 minute. If a failure in the temperature monitoring loop occurs, openvalve command is given.
SYSTEM SHUT DOWN
Please refer to instrument list for applicable shut down functions.If a shut down function is initiated, the PLC will give shut down command to thepower packs in sequence. The first power pack stops immediately. The delaybetween shut down command of each power pack is 0.75 seconds. The feed pumpwill stop together with the first power pack.

Condition monitoring of your cargo pumping systemcarried out in Rotterdam, Houston, Singapore and Bergen.iiFRAMO
'-"
"-"
To perform maintenance based on condition monitoring is proven cost effective. A continuous followup on the condition of the cargo pumping system will give optimum lifetime of the components in thesystem, and unforeseen shut down and break down will be reduced. r--
LEVEL 1: Portable cleanliness indicator
LEVEL 2: Particle counter Promo test laboratory
vThe primary advantages are:. Secure systemapproval fromvarious authorities. Avoid interferencewithvessel operation. Preventiveactions to limitemergency repairs. Increased lifetimeof hydraulic components. Reducedmaintenance cost. Optimum performance of your cargo pumping
system. Betterpossibilityto plan the maintenance and to
have spares available
The condition monitoring program offered by FRAMOcontains:
. Attendanceby qualifiedpersonnellat a harbourwith FRAMO service station ~
. Communication with ship's staff to land oilsample if vessel is not in FRAMO station area
The oil analysis is an important parameter foranalysing the condition of the hydraulic system. Ourprogram contains 3 different levels, as follows:
LEVEL1: Simplifiedcleanliness test, quarterlyTest to be carried out onboard the vessel bymeans of a portable cleanliness indicator.Guidance info to verify if the oil is withinFRAMO's acceptance criteria or not.
LEVEL2: Particlecountingand water contenttest, '-'semi-annualOil sampleto be analysed at FRAMOtestlaboratory acc. to ISO 4406.Number and size of particles.Water content
LEVEL3: Fulloil analysis,annualOil sample to be analysed in a chem. labinstitute.
Spectral analysis of the oil including:Flashpoint.Anti wear composition of the oil.Specific gravity.Water.
Viscosity.Total acid no.Chlorides.
J
To get a reliable oil sample, it is important that the correct procedures are followed and the samesampling point is used each time. If the ship does not sail in an area with a FRAMO service station,certified clean bottles and shipment containers will be applied together with labels and detailedprocedures.
During our visit in one of the "FRAMO ports" we willinspect additional important parameters which will beevaluated to establish the overall condition of the

GENERAL r'-I
In this Service Bulletin we would like to highlight the importance of keeping yourHydraulic System "air free", to avoid failure, and in the worst case break-down ofcompone.nts.
Air in a hydraulic system is a contamination and is critical to the performance andlifetime.
Design practice of the hydraulic system foresees neither air in the oil, nor air as freepockets-in the piping system.
During commissioning at the shipyard, after oil filling and flushing, air venting is animportant part of the "start-up procedure".
Air venting must be a part of your Periodical Maintenance program.and is important after every service. ,.....
'wi
Any air in the system will accumulate to "high points" in the system; where ventcocks shall be installed.
. Necessary time for air venting after service I repair must be included in thetotal scope of work, even if time schedule is limited.
HOW TO PREVENT AIR ENTERING INTO THE SYSTEM,'-'
. Do not open a hydraulic system unless service/repair is required.
. After service/repair the air shall be vented as close to the actual component aspossible to avoid any "locked-in" air pocket(s) to be mixed into the oil after start-up.-Air vent the component prior to opening service valves(s).
. Check that all connections, Q-rings, gaskets, shaft seals and threads are tight.-Air can be sucked -in from any opening to atmosphere.

4.0 EVALVATION OF THE PURGING RESULT.
4.1 Cargo leakage.
Cargo in the cofferdam can come from shaft seals, flange face seals in pipestack/pumphead ordamage (cracks)-on the pipestack/pumphead.A small leakage rate over the shaft seals up to about 0.5 lIday during pump operation isnonnal, and replacement of seals should not be necessary with this leakage rate. For shortperiods of time, higher leakage peaks can occur. The leakage rate is also depending on thetype of cargo. Some cargoes like naphtha, condensate etc. penetrate the shaft seals more easilythan lub. oils, vegetable oils and other viscous cargoes.If the leakage rate is up to about 2 litres/day, the pump must be purged a couple of times daily,and inspected as soon as possible to find the reason for the leakage.Intensify the purging if the leakage rate is increasing above acceptable level. If this is notkeeping the leakage under control, do not operate the pump; use theportable pump todischarge the cargo.
"-"
The development of a cargo leakage can be followed if purging is done according to specifiedintervals. Thereby maintenance work can be planned, and unexpected shut down due toleakage can be avoided.
4.2 Hydraulic oil leakage.
Hydraulic oil in the cofferdam can come from shaft seals, flange face seals in pipestack/pumphead or damage (cracks) on the pipestack/pumphead.A small leakage rate into the cofferdam up to about 10 ml/h (0.25 l/day) from the mechanicaloil seal or lip seal during pump operation is normal. For short periods of time, higher leakagepeaks can occur.If the leakage rate is increasing above acceptable level, the pump must be purged a couple oftimes daily, and inspected as soon as possible to find the reason for the leakage.Intensify the purging if the leakage rate is increasing above acceptable level. If this is notkeeping the leakage under control, close the hydraulic service valve. Do not operate the pump,use the portable pump to discharge the cargo.

6.0PRECAUTIONS TO BE TAKEN WHEN HANDLINGSPECIAL TYPES OF CARGO
The main rule is to have the cofferdam clean, dry and vented to atmosphere through the exhausttrap vent line, in order to avoid any leakage's.However, when handling certain groups of cargoes it may be an advantage to fill the cofferdamwith liquid to improve the seal life time and to avoid cargo blocking the cofferdam.The list below gives recommended type of liquid in the cofferdam for some groups of cargoes.This is a general advice, as the ship crew have to learn by experience which type of liquid givesthe best result for the great number of different types of cargoes.
' '"
'-"
Valve for regulation~
To fill liquid in the cofferdam, disconnect theexhaust trap piping from the pump top plate. Using asuitable adapter, fill the liquid through the cofferdamcheck pipe. Open the snap-on coupling on thepurging valve block to ventilate the cofferdamduring filling. (Connect a open female coupling orsimilar.)
A circulation of liquid through the cofferdam can bearranged in the following way:-Connect liquid supply to the snap-on coupling onthe purging valve block. The supply line must alsobe equipped with a valve to regulate the liquid flow.-Open drain valve on the exhaust trap, and collectthe return liquid here.
Acid cargoesAfter discharging and purging is finished, it can be an advantage to circulate fresh waterthrough the cofferdam to remove all residue after a leakage.
Polvmerising cargoes. (TDL MDI)Fill cofferdam with 5-10 litres of DOP to avoid blocking of cofferdam.
Crystallizing cargoes.Fill cofferdam with 5-10 litres of fresh water. The cofferdam may also be filled completelyand arranged with a small water circulation

PhenoL caustic etc.
A circulation of hot water through the cofferdam can avoid clogging. (But remember some ofthese types of cargoes are very dangerous, poisonous).
Heated oil products (fuel oiL crude oil)
Fill cofferdam with approx. 5-10 litre of diesel oil/'vvhitespirit to keep any leakage intocofferdam in liquid form. This is especially important after stripping and during tank cleaning.
NOTEWhen filling liquid in the cofferdam, it is important that the hydraulic oil return pressurealways is higher than the pressure will be in the liquid filled cofferdam. This is especiallyimportant on hydraulic systems with non-pressurised return line, as the pressure differencebetween the return line and the cofferdam will be negative if the cofferdam is filled with tomuch liquid. .

'-'BEFORESTARTINGDISMANTLINGOF THECARGO PUMP
Ifthe purging routinehas detected a cargo leakage (more than 2 I / day *), and theevaluation indicatesthat action mustbe taken, firstthing you have to do is to identifytheleakage. Thebest way is to pressure test the pump's cofferdam.
Never start any dismantling of the cargo pump before you know: if,what, and where, you have a problem.
PRESSURETESTOF THE CARGO PUMP'S COFFERDAM,-
CARGO LEAKAGE
If a cargo leakage is detected the complete cargo pump's cofferdam has to be pressuretested to identify the leak. We have learned from FRAMO on board training that crew onsome ships start to automatically change the pump's cargo seal as soon as there is acargo leakage - although the leak may be somewhere else. This is waste of time andmoney. So always identify where you have a leak first!
J
Thecofferdamcan be pressure tested by blinding off the purging medium reliefvalve bymeans of a rubber gasket. Dismantlethe cofferdams's riser pipe flange on the top coverplate and installa test flange with pressure gauge (see figure 1). Connect the purgingmediumto the test flange and increase the pressure to 3 bar.
Afterapproximately 5 minutescheck all flanges around cargo seal, riser pipe, and allother connectionsfor possible leakage. Use soapy water for better detecting of thepossible leakage. /
'-'Note:Ifthe cargo leakage is not possible to identify, and the 3 bar pressure is stabilized
for a long period of time during the pressure testing, - it is still possible that thecargo seal in the pump is worn out, and have to be changed. The reason couldbe that the 3 bar pressure in the cofferdam is pressing the upper lip (facing thecofferdam) around the pump shaft. Dismantle the cargo seal for control.
If this is not the case, and the cargo leakage is not possible to detect, you have to split thecargo pump, and pressure test the main components separately.
~* See Service Bulletin no. 13.
PRECAUTIONSTO BE TAKEN BEFORE THE SERVICEJOB IS FINISHED
. After the leakage has been identified and repaired, and the repaired part has
been pressure tested, the cargo pump can be reassembled.
Remembe(, cleanliness is absolutely necessary.
. When the mounting is completed, pressure test the complete cofferdam with max.
3 bar pressure as described earlier.
. After minimum 5 min. check all flanges, cargo seal and other critical points with
soapy water for possible leakage.
. Leave the 3 bar pressure in the pumps cofferdam for at least 30 min., and check
that the pressure is stable.
. Necessary time for control must be included in the total scope of work, even iftime schedule is limited.
. Fill the pumphead and pipe stack with hydrooil by opening
the ball valve on the pressure line on deck.
Open the venting plug on the non return valve on the return
pipe on deck.
. Keep the venting plug open and start the cargo pump
carefully for test running.
. Close the venting plug when clean airfree oil is coming out.

~HYDRAULIC OIL LEAK
If the cargo pump has a hydraulic oil leak you normally have to split the pump to identifythe leak. A hydraulic oil leak is very rare under normal conditions, but if a hydraulic oilleak does occur, there could be three reasons:
a) Hydraulic oil seal - the life time is normally very high (> 10.000 running hours).
b) Crack in pipe stack - can occur if the cargo pump is vibrating heavily for someabnormal reasons.
c) Corrosion attack in seal rings grooves can occur after long service.

SUBJECT:FRAMO SINGLE AND DOUBLE CARGO SEALS~
Statistics.show that these seals are changed mostlywith the same serviceintervals,and we recommend that these seals are changed at the same time,based on following reasons:
- Main part of the iob is to open the pump.
- The remaining lifetime of the single cargo seal islimited when the double seal is worn out.
- From the purging, only the condition of the doublecargo seal will be shown. The condition of the singlecargo seal can only be evaluated after dismantling. '-..J
Bydelivering these seals as a set, stock keeping on board will be easier, as itwill be easier to identify for how many pumps you have seals in stock. Onepackage will also take less space, and this new package is made of an envi-ronmentfriendlymaterial.

Total Pump Service I
The shaft seal is one of the most critical parts of a pump.To ensure a long lifetime of the seal it is important to have a detailed knowledge of the pump design, the liquid handled
and the seal system. The mechanical seal is also in many cases the part that limits the Mean Time Between Failures for
the pump. By performing all the activities in our Maintenance Facilities, a complete failure analysis and a total pumprepair can now be offered to our Coustomers at reduced Turn Around Time. This will also ensure the best Quality of the
job. If the duty or other operational circumstances makes it necessary to upgrade the seal arrangement, our Engineering
Service group will evaluate all consequences, and the best solution proposed to our Customers.
Seal design and upgrade. A successful new, or upgraded seal design requires total
knowledge of the system in which the seal is an integrated
part.. Our engineers have many years of experience from pump
and seal design, including troubleshooting and testing of
seal system for offshore- and marine applications.. Experienced technical assistance in selection of seals and
application studies is available.
J
Availability. Pump downtime can be greatly reduced if spare seals are
available when required.. For most FRAMO pumps new seals, or reconditioned
Exchange Units are available.. The exchange program can be further developed
in agreement with our customers.
Reconditioning. In our dedicated Mechanical Seal Shop most types of seals J
can be repaired or totally reconditioned, regardless of
material quality or seat configuration.. Depending on condition, reconditioning is carried out atthree levels:
A) Re-Iapping of both sealing surfaces + renewal of
elastomers, springs and fasteners.
B) As A + renewal of stationary seat.q A + B + shrink in new seat material.. Lapping can be done to Plane, Concave or Convex
configuration.. The shop contains a full range of modern equipment and
tools, operated by highly qualified personnel.. All activities in the shop are subject to thorough QualityControl in accordance with relevant ISOstandards.. Tools and equipment are surveyed and calibrated in
accordance with procedures and standards.. Seal Condition Report issued on request.

Dear Customer!
In this Service Bulletin we will draw your attention to the Local Control Valvesand Ball Valves for the cargo pumps. By correct operation and maintenance ofthese valves the life time will be increased and your costs reduced.
~
~
Local control valves:
All cargo pumps have a local control valve. There are different designsdepending upon generation.
-"
The main purpose of the local control valve is:
Control the cargo pump during stripping of the cargo tank.Stepless capacity control locally from deck, if required.
During stripping it is important to control the pumps from deck.The benefits of this are:
Improved stripping result.Reduced wear and tear.Better observation of fluctuation in hydraulic pressure.Better observation of pump's vibration.Immediate stop of cargo pumps upon completion of stripping.Regular operation of the local control valves will ensure properlyfunctioning valves.
~
~
Special tool:
To improve the operation of today's generation local control valves on cargopumps equipped with the stainless steel Speed Torque Control valve (STC), aspecial tool is available.

Ball valves:
In all Framo Cargo Pumping Systems designed after 1983, the ball valve onthe hydraulic inlet line to each cargo pump shall always be in open position(even whe~ the cargo pump is not in operation). The same applies to systemsdesigned before 1983, whichl1ave been upgraded with pressurised return line(overpressure system). This to ensure the safety of having a pressurised hydraulicreturn side with a higher pressure than the static cargo pressure.
Also on older ships built before 1983, we recommend to keep the ball valvesopen. This to avoid opening the valves with high hydraulic inlet pressure.Operating the valves with high inlet pressure will reduce the valve's lifetime.
To avoid sticking we recommend to move all ball valves on deck quarterly,when the main hydraulic system is not in use.
Ball valve
Mild steel valves are delivered with primer only. During replacement a propercoating must be applied to the valves, and a corrosion protection must bemaintained.
To increase the lifetime of these valves and reduce the costs:- Use them- Move them- Paint them
If you need any further information or assistance, please do not hesitate tocontact any of the worldwide FRAMO offices.

NORMAL OPERATION
. Start/stop of power packs
BEFORE STARTING THE MAIN POWER PACKS
Oncethe system is completedand the ship is in service, the hydraulicsystemshould always be kept pressurized by running one of the feed pumps in lowspeedwhen main power packs are not running. The reason for this is to avoid the hydralsystem being contaminated by cargo through shaft seals on submerged cargopumps or by sea- or freshwater through hydraulic oil cooler. In addition, this willgi'a continuous air venting and cleaning/filtrationof the hydraulic oil.
The followingare to be checked before starting the main power packs:
That the cooling pump for hydraulic oil cooler is running.
That the cooling fan for power packs is running.
That necessary numbers of generators are running.
That the potentiometer for system pressure is in minimum position.
That the speed control valve for all consumers are in dosed position.
That the cargo pump's cofferdam is purged.
Start the main power packs.
Never run hydraulic pumps with pressure below 50 bar (impossible if thesystem adjustment is correct).
Set the main hydraulic pressure to approximately 15 bar above the highestconsumer (hydraulic motor) if hydraulic oil temperature is above 20°C.
If the main hydraulic pressure is always set to maximum, or excessivelyhigher than consumer (hydraulic motor), energy for the difference betweenmain pressure and the consumer pressure will change into heat. Loss ofenergy means waste of fuel.
If the oil temperature is below 20°C, circulate the oil (through the heating and ventingvalve installed in the system) for heating with only one power pack runningaccording to Fig. 1.
Operation temperature for Framo systems
(Based upon hydraulic oil viscosity ISO VG46 according to ISO 3448)
Fig. 1
5.1.5 After operation of the system is completed and the main power packs are not to beused, the system can be stopped as follows:
- Reduce the hydraulic system pressure to minimum.
- Stop the main power packs.- Stop the cooling water pump and fan.- Stop the excessive generator sets.- Stop the feed pump and restart in low speed.
Note! Always leave one of the feed pumps running in low speed to maintain over-pressure in the hydraulic system.

Pressurizing system when not in operation
If by accident cargo should leak into the hydraulic oil system when the power packsare stopped, the mixture of oil and cargo would ruin the plant. To prevent this, thehydraulic oil pressure must always be higher than the cargo static pressure. Whenthe hydraulic system is not in operation, one of the feed pumps will keep a hydraulicpressure of approximately 4 bar.
One of the feed pumps must always be running in low speed and all valves inmain return line and in front of all cargo pumps and other consumers must beopen.
Emergency stop - Start-up after service
EMERGENCY STOP
It is important that emergency stop buttons are used in emergency only and not foroperational stop of the system. An emergency stop stresses the system, and shouldbe avoided:
Emergency stop buttons should be activated when the following conditions occur:
Damage on hydraulic pressure pipes or hoses that leads to leakage.Critical pressure pulsation in system (hunting).Critical vibration on power. packs.Damage on cargo lines. .
The following conditions lead to shut-down of the system:
Low low oil level in tank.Closed valve in return line.Low feed pressure.Feed pump failure when running in high speed.
After a shut-down the error must be located and repaired before restart.
For restart: Reset system. Refill oil if necessary in accordance with normalprocedures. Vent the system thoroughly and start up inaccordance with normal procedures.
START-UP AFTER SERVICE
After service follow the same routines as described above and in separateinstructions in section 8 for the component and/or part of system that has beenserviced.

6.1. THE DIFFERENCE BETWEEN A POSITIVEPUMP, AND A CENTRIFUGAL PUMP.
The difference between a positive pump (screw pump,piston pump) and a centrifugal pump is shown in d ia-gram 6.1. A and 6.1. B.As shown in fig. 6.1A the capacity of a positive pump isalmost constant and independent of the head. Thedecrease in capacity is very small when the back pres-sure rises. and this is due to small internal leakagesin the pump itself.When looking at fig. 6.1. B. it is seen that the capacityof a centrifugal pump varies very much with the head.If the head is very low (when pumping justover therail for example) the capacity is large. But if the headis very high. the capacity reaches zero.

Highlights/advise for handling and operation ofFRAMOPortable Pump
How to connect the pump to the main system1) . Alwaysconnect the snap-on couplingon the return side first.2) Then connect the pressure side in the same way.3) Be sure that the snap-on couplings are secured by means of the locking
ring- and that the locking screw on the starting head (flow control valve)is secured.
Start the pump slowly and run it on deck for about 30 sec. to make surethat oil flow is free and the pump runs normal,- flush the seal area with water.Never hook-up the portable pump to the main system without using a flowcontrol valve for speed control of the portable pump!
Correct operation of equipment during pumpingHandling:. lower the portable pump into the cargo tank by means of a sling, and newer
by the hoses.. For easy and controlled handling of pump and hoses in/out of tank use the
FRAMO portable hoist.

. The portable pump to be placed on the tank top in a vertical position.
. Secure the cargo hose and hydraulic hoses at the tank hatch on deck to avoidstress on the portable pump and to avoid the pump tipping over.
. Materials in the portable pump are of stainless steel AISI 316l, and the flexiblehydraulic hose neoprene rubber as a standard.
. The portable pump parts exposed to cargo resists most chemicals and acids,but the neoprene rubber in the flexible hoses has some limitations.
. For frequent discharge of cargoes with destructive effect on the neoprene hoses,FRAMOcan offer special chemical resistant, or stainless steel protection hoses.
. Another alternative is to avoid contact between the cargo and the flexible hoses
by lowering the pump with liquid level in tank. Some companies are using thisas a standard routine, but here the operator must pay extra attention to avoiddry running of the portable pump.

Starting - Discharging:. Start the portable pump by turning the handwheel on the starting head anti-
clockwice.
. Discharge capacity will increase if the back pressure is reduced to a minimum.If possible use the portable pump to transfer the cargo to another cargo tankand discharge the cargo ashore with the main cargo pump.
Cleaning/ preservation after useStopping:. Stop the portable pump - by closingthe flowcontrolvalve.. Closethe ball-valveon pressure side snap-on coupling-station.. Relievethe pressure in the hose by opening flowcontrolvalve a short period
of time.
Cleaning:. For cleaning the pump inside, run the pump in fresh water in a drum on deck.. For cleaning the pump and hoses outside, use steam or flush with fresh water,
according to what type of cargo has been discharged.
Disconnection:. Disconnect the pressure snap-on coupling first.. Drain off approx. one cup hydraulic oil from the flex. pressure hose.. Check that the snap-on coupling is clean and corrosion protected (greased).. Put on the protection cover.. Disconnect the return side snap-on coupling the same way.
Storage on board
Forcastle/Bosum store. The portable pump and flexible hoses must be cleaned and ready for new
pumping job before the equipment is placed in storage room onboard.. The storage room must be clean and dry, and the pumping equipment
must have easy accessibility.. The flexible hoses are filled with hydraulic oil. Drain off approx. one cup'
of oil from the hoses before storage (when disconnecting from the mainsystem).
. Control the bending radius for the flexible hoses during storage(min. 800 mm).
. Control that the units are safely supported, and check that the snap-on
couplings and starting head/flow controlvalves are greased and protected.

Preventive Maintenance, RoutineTesting of the portable pump unit
QUATERLYCHECK ROUTINES
. Control the snap-on coupling stations on deck.Remove the protection cup - drain off any water - check the o-rings - move
the ball valve and all the moving parts - grease the units.. Control the portable pump unit with flex. hoses and starting head in thestorage room.
Check that the unit is supported safely.Check the flexible hoses and be sure that the hydraulic pressure inside is
relieved (max. 6 bar).Check the snap-on couplings and the starting head and repaint or grease if
necessary.
TESTING OF THE PORTABLE PUMP
. Once a year we recommend to run a function, capacity and drill test of theportable pump.FRAMO suggest the following procedure:. Hook-up the unit to the main system as standard routine.. Hoist the portable pump into the sea (the ship is not sailing) or into anavailable cargo tank with water.. Run the pump with full speed (control that the locking screw on the startinghead is in a correct secured position to prevent the hand weel from turning of~.
Never start the pump if this locking screw is missing!. Run the pump for approx. half an hour and control the hydraulic pressureand the pump capacity.. Make a visual control of the complete unit.. Then run the pump with reduced speed in a drum with fresh water on deckfor flushing and control for any hydraulic oil leakage.
FRANKMOHN SERVICESAS can offer you this test, or we can offer the testcombined with a one day training and drill test of the crew when the ship isin Rotterdam, Houston or Singapore. If you are interested, please do not hesitateto contact FRANK MOHN SERVICESAS for more information.

tI A properly maintained systemwillreduce unnecessary problems andincrease the ship's turnover.
-FRAMO J
GeneralFor all ships trading world-wide, it will in the near future be required to have an approvedQuality Assurance System - ISO 9002 on board.
An important part of your ship's Q-A System will be a Planned Maintenance System for all theequipment on board, i.e. job specifications, carried out by, approved by, inspection intervalsas well as a separate record book for logging of results.
There is no doubt that a properly maintained system will reduce operation costs and obtain asafe and sound ship.
Planned Maintenance System for FRAMO Cargo Pumping System ;
Approximately 1.200 ships are today equipped with FRAMO Cargo PumpingSystem.Someofthem have already an approved Quality AssuranceSystemon board, but the majority will haveto develop and implement a Q-A Systemin the near future.
To give these «FRAMO Ships» some guidance, we have in this Service Bulletin proposed a ba-sic Planned Maintenance System on the next pages. The equipment on board, as well as thetype of ship and trade may differ from ship to ship - our proposal is therefore to be understoodas guidance only.
Explanation to the following basic Planned Maintenance System
«Equipment»: is the main components in your specific FRAMO CargoPumping System.
..-J
«Job Specifications»: specifies the various activities.Note! A visual inspection of the cargo pump's top platemeans visual control of local control valve, purging valve,ball valve, pressure gauge, et cetera. Repair whennecessary.
«Drawing No.» : refer to the drawing in the FRAMO Service Manual.
«Maintenance instruction»: refer to FRAMO Service Manual.
«Carried out by/Approved by»: can vary from ship to ship, but it is a must that theresponsibilities are clearly defined.
«Inspection intervals»: can vary according to type of ship and trade and yourown experience.

Ten Rules to remember...1. Purge the cargo pump's cofferdam before and after discharge. Log and
evaluate the purging result. Take necessary action.
2. Never start any dismantling of the cargo pump before you have identified
the problem. Always pressure test the cargo pumps cofferdam to identifyany leak. Always remember to use the correct tools from the FRAMO toolbox.
3. Use only genuine FRAMO parts.
4. If you have any problem with capacity, stripping or parallel pumping,check the cargo pump's condition against the performance curve
5. During discharge: Regulate the hydraulic system pressure to approx.15 bar above the highest consumer - regulate cargo pump capacity byhydraulic pressure, not by throttling of cargo valve. l!
6. Avoid air in the hydraulic system. Deairate the system on a regular basis.
7. Keep the hydraulic system clean. Cleanliness is absolutely necessary.
8. Take a hydraulic oil sample, every 3rd month for particle counting (ISO4406). Every 12th month full analyze according to FRAMO standard1400.063.
9. Never mix the hydraulic oil with lub. oil.
10. Implement a planned maintenance system for the complete cargopumping system.

Dear Customer!
RECOMMENDATIONSTO REDUCEYOURMAINTENANCECOSTS J
With the implementation of the ISM-code, a planned maintenance program is required. In this respect we would like to
draw your attention to the part of the program concerning the FRAMO cargo pumping plant. Based on experience, new
technology and feedba~k from our customers, the maintenance recommendations have changed over time.
We recommend you to update your program according to this information.
Hydraulic Oil Filters - Change IntervalsIn the original instruction manuals you may find that thefilters have been recommended changed once a year,
even without any filter alarm. Today the filters are to be
changed based on condition only, either from a filteralarm due to high differential filter pressure or from the
analysis result of oil samples.
v
should no filter alarm occur and your hydraulic oil is in
good condition {cleanliness level better than ISO code16/12} the filters should not be changed.
We recommend that you draw a sample for particle
contamination analysis four times a year. In addition, a
full analysis should be carried out once a year. FRAMOcan offer assistance during oil sampling, monitoring and
trend analysis as well as providing advice of preventivemaintenance.
Reduced Water Content in Hydraulic Oil -Increased Lifetime
Previously the maximum allowed water content in the
hydraulic oil was 0,1 %. Experience has shown that a low
water content in the hydraulic oil improves lifetime of
hydraulic components as well as of the hydraulic oil itself.We have found that the maximum water content should
be below 0,05% or 500ppm.
~
Thewater contentshould normally be well below300ppm.
Any increase in water content must be investigated, thecause corrected and the water removed. To remove water
we may offer rental of purifier and / or special waterfilter. Note that this is only a temporary solution - the
cause of the water ingress must be located and repaired! --I

Testing of Cargo Pumps
In the past we have recommended you to test run your cargo pumps against closed discharge valve, once or twice a
year. Such a test requires calibrated pressure gauges and there are several possibilities for error as well as the amount
of work involved. Provided no problems are experienced during discharge, parallel pumping or stripping, there is noneed for periodic testing of the cargo pumps.
The cargo pump test is useful when trouble shooting a specific pump.
Testing of cargo pumps is recommended in view of a planned docking.
Pre-docking tests are necessary to set up a
proper repair schedule to determine which
cargo pumps will need an overhaul.
Cargo pump testing is also carried out duringon board training courses.
This is to inform the crew of how to do the test
and learn to evaluate the results.
In view of above we kindly ask you to change
this activity from periodic to condition based in
your planned maintenance program.
Framo Tool Boxes - Use SpecialTools and Reduce YourService CostsExperience has shown that the originally supplied special tools contained in the FRAMO tool boxes are often lost or
damaged over the years. Doing maintenance on the cargo pumps without these tools may cause damage to the
pump as well as to the new parts, increasing your total costs. It is better to renew the contents of the tool box than
paying for damage during repair or even malfunction during the following discharge operation.
please include an annual check of the FRAMO tool box in your maintenance program.
Spline LubricationExperience indicates that inspection and lubrication of the spline connection between the hydraulic pumps and thePTO output shafts is neglected, causing abnormal wear on the spline. This is also the case on electric motors withspline connection.
It is very important to have a scheduled routine for control of this lubrication. We recommend that the oil on the
spline is changed every 800 running hours, or every six months, whichever comes first.
