Offshore Accidents

GENERAL Safety zones around oil and gas

installations , What is a safety zone? A safety zone is an area of 500 m radius established

automatically around all offshore oil and gas installations which project above the sea at any state of the tide. Some sub sea installations also have safety zones . Vessels of all nations are required to respect them. It is an offence to enter a safety zone except under the special circumstances .

The purpose of a safety zone is to protect : the safety of people working on or in the immediate vicinity

of the installation the installation itself against damage. They also provide the

additional benefit of protecting fishermen and other mariners by reducing the risk of collision with the installation

Offshore Platform 500 M Zone Entry Permit

Introduction– The 500 meter Zone permit has been established to

enhance verbal communications between the offshore platform OIM and all vessels, rigs and barges associated with the company Offshore Operations and Projects.

– This will allow the Platform OIM to be aware of the vessels entering his area of responsibility and their intent.

It also allows the OIM to describe any potential safety or operational concerns and local vessel traffic to the Vessel Masters


Objectives The 500 meter Zone permit is intended to

ensure:– Communication links are clearly defined– Current work or operational conditions of the

platform and Vessel are discussed, i.e. isolations, anchor pattern requirements, sub-sea pipeline location, etc.

– Permission is granted before entering the 500 meter zone.


Application of the 500 Meter Permit Before vessel enters the 500 meter Zone

– the Vessel Master completes the zone entry permit by: Describing the vessel name, vessel type , date,

platform, and reasons why to enter. Entering the vessel preparation information Contacting the platform and requesting permission

to enter. As applicable, request for a copy of the Isolation

Confirmation Certificate – ICC, in English. Testing the communication link in the event of

emergencies. Fax the Form to the Platform OIM for his approval

to enter.


The Platform OIM will complete the lower section by: Providing the Vessel Master with a copy of the ICC Describing current operational conditions of the

platform Informing of other local vessels operating in the

area. Verifying communications with the Vessel. Granting permission to enter or decline based on

safety or operational upsets. Faxing the signed form back to the vessel

After entering the 500 meter zone, the OIM and Vessel Master contact each other at a minimum twice per shift.

Leaving The Helicopter

• On landing you must not unfasten your seat belt or life jacket until the indicator lights have been switched off or you have been instructed to do so by the captain of the Helicopter.

On leaving the Helicopter you must never: Go round the tail of the helicopter. Duck under the tail of the helicopter Put on caps, safety hats etc until you have left the

heli-deck. The dispatcher will be in position at the cargo door,

do not go beyond his position and be ware of the tail rotor.

If you have to go to the other side of the helicopter go round the nose of the helicopter never round the tail.

Leave the heli-deck immediately, do not stand on the heli-deck talking to others.

Boarding the vessel (From the Dockside)– Boarding the vessel from the

dockside is a relative easy and safe operation since the vessel is moored against the jetty in calm waters

– Boarding may be simply stepping onto the deck of the vessel or by walking up a gangway. However, if a gangway is not provided the vessel must be moored "Close snubbed" alongside the dock with no space between ship and jetty where persons may fall in.

•All persons traveling to platforms, barges or other offshore facilities shall strictly adhere to the following instructions and other instructions pertaining to the vessel or as may be advised by the captain

Traveling By Supply Boat

Traveling By Supply BoatTraveling By Supply Boat

– There must be a life jacket aboard the vessel for every person sailing on the vessel. All persons must be shown the location of the life jackets.

– All persons, on boarding the vessel, should be advised as to safety regulations and instructions for passengers. i. Emergency procedures

ii. Location of life rafts

• Ring Buoy

•Quick Access?•Line attached?

•Light attached?

• Life raft mount

• Service Date

• Hydrostatic release Date

• Life raft capacity *

General Precautions

• The following precautions apply in all circumstances:-

• Weather and sea conditions must be such that the boat Captain is able to keep the boat close to the

platform and is happy for the transfer to take place

•During the transfer, hands should be kept free. Baggage etc should be handed across after the

transfer is complete

•A life jacket must always be worn during the transfer and while on the boat landing platform

•Swing ropes must be in good condition. At least 3 swing ropes should be provided

•Particular care should be taken to keep feet and legs clear of the platform landing face so as to avoid being

trapped by the boat bumping against the platform

Supervision

•The transfer should be done under close supervision from the area

authority supervisor and/or a representative from the boat crew.

•Boat Captain -The Boat Captain will prohibit transfer if he is not satisfied it

can be undertaken safely

•Any broken or missing safety equipment such as gratings or

handrails must be reported immediately to the area authority of

the platform or the boat captain.

DISEMBARKING AND EMBARKING AT A BARGE

Contractors/subcontractors personnel require to disembark to or embark from a barge. The method of disembarkation and embarkation will depend entirely upon the weather condition and sea state, however, this must never be attempted without wearing a life jacket and someone standing by to render assistance or raise the alarm should anyone fall overboard.

THIS IS A VERY DANGEROUS OPERATION AND SHOULD ANYONE FALL BETWEEN THE VESSEL AND THE BARGE HE COULD BE SERIOUSLY INJURED OR CRUSHED TO DEATH BETWEEN THE TWO VESSELS.

Disembarking and embarking (at the platform) Weather conditions and the sea state will dictate the method of

disembarkation from the vessel to the platform and embarkation onto the vessel from the platform.

A. In calm seas the vessel shall come along side the boat landing of the platform and hold station tight against the fenders

B. All personnel shall wear a life jacket and disembark onto the boat landing. Platform HSE engineer or persons delegated shall stand by on the boat landing to give assistance as required.

C. Embarking from the platform in calm seas will be done in reverse of a, and b, of this section.

D. When weather does not permit the vessel to come alongside the boat landing, embarkation and disembarkation shall be by personnel basket. All persons shall wear a life jacket during this operation.

WARNING: Never disembark or embark over the stern of the vessel since, should you fall overboard you will be sucked into the propellers and killed.

Cranes and Personnel Baskets Numbers of recorded personnel transfer basket incidents

are low, but basket transfers to or from offshore installations are considered a high-risk operation.

Personnel baskets should only be used in exceptional circumstances, ie emergencies or when transfer is essential and it is not practicable to gain access by less hazardous means.

All personnel baskets must possess a current thorough examination report undertaken by a competent person in accordance with LOLER regulation 9.

The safe working load (SWL) should be clearly marked on all personnel baskets, together with instructions for their use.

Procedures should include the methods of maintenance and storage together with instructions related to inspection before use.

'Freefall' or non-powered lowering should not be adopted when personnel are carried in baskets.

The following minimum lifting practices are recommended for all cranes assisted personnel transfer net devices:

Any offshore facility making personnel transfers with a personnel carrier should have a written procedure for this task.

A pre-use inspection should be conducted prior to any personnel carrier transfer.

Cranes assigned to personnel lifting duties should be suitable for this purpose per relevant API spec.

Crane operators assigned to personnel lifting duties should be certified and competent to perform this task per 46 CFR 109.527.

A tag line should be affixed to all personnel carriers. Crane hooks used for personnel transfers must have a

positive locking Latch

Cranes and Personnel Baskets

Cranes and Personnel Baskets Only approved personnel carriers should be used

for lifting personnel per API RP spec. Personnel carriers should not be used as a

workbasket or cargo net. Before any attempt is made to lift personnel with a

carrier, clear instructions should be given to all persons involved.

No person suffering from acute sea sickness or vertigo shall be transported by personnel carrier.

Any individual has the right to refuse transfer by a personnel basket.

Cranes and Personnel Baskets All personnel riding on a personnel carrier should stand on

the outer rim, evenly spaced, and adjacent to a sidewall opening in the netting, facing inward. Passenger forearms should be interlocked on inside of sidewall netting.

If crane operator’s view of the primary signalman is obstructed, the personnel carrier should not be moved until alternative communication or signal devices are placed in service.

A designated primary landing zone should be marked in a safe area as determined by a Job Hazard Analysis (JHA).

When transferring personnel, the personnel carrier should be lifted only high enough to clear obstructions. It should then be gently lowered to the deck.

The crane operator may refuse to lift any person who does not comply with the operator’s instructions.

.

Cranes and Personnel Baskets Personnel will be transferred by basket in greater

safety and with less apprehension if they have received training in the techniques involved

Transfer operations should be conducted during daylight hours. However, the OIM may agree night-time transfers provided that the circumstances requiring transfer by basket are exceptional and the operation is conducted under their personal direction.

People being transferred should wear life jackets, suitable clothing and immersion suits. All life jackets should be equipped with suitable means of illumination during night transfers. Appropriate rescue and recovery arrangements must be in place (eg standby vessel equipped with a fast rescue craft ready to launch).

Responsibilities of personnel basket transfer The Offshore Installation Manager ( OIM )should:

– be satisfied with the fitness, training and briefing of the people to be transferred;

– be content with the suitability of the vessel; – know the limitations of visibility and sea state; – be aware of the limitations on transfer by night; – be aware of the suitability of the crane for personnel transfer; – check the wind speed limitations on crane operations; – establish and maintain communication with the Master of the

Vessel; – be satisfied with the competence and experience of the crane

operator; – ensure appropriate emergency precautions are in place, eg notify

the standby vessel before the transfer; be satisfied with the inspection and testing of the

personnel basket

Responsibilities of personnel basket transfer

The Master of the Vessel should confirm to the OIM that:

– the transfer has been accepted and the procedures understood;

– the vessel has a satisfactory station keeping capability;

– the deck crew have been fully briefed;

– the people to be transferred have been adequately briefed and are fit to be transferred.


The crane operator should establish that: – the crane is fully operational; – the wind speed is satisfactory for safe

operation; – the requirements and procedures have been

understood; – the banks man has an unobstructed view and

the transfer areas are clear; – adequate communications have been

established with the vessel Master and banks man.


The Banks man and Deck Supervisor should ensure that:

– the transfer procedure is understood; – they can be clearly identified as banks man and deck

supervisor; – the personnel basket is correctly used; – the individuals are fit to transfer and have understood

the procedures; – proper communications have been established;

– they each have a full view of the transfer area.

ON THE PLATFORM On arrival at the platform, site personnel shall report immediately to

platform manager and / or HSE manager who will carry out the following :

a. Conduct each person to his accommodation. b. Instruct the arriving site personnel on the emergency procedures and

direct them to their life raft/muster station. c. Familiarize everyone with the escape routes and the location of the

first aid room. All site personnel shall sign the log book which will show their

presence on the platform and that they have received HSE induction. On leaving the platform, all site personnel shall sign off in the logbook.

This is of the utmost importance since, in the event of an emergency, rescue services must know how many persons were on the platform, how many have been accounted for and how many are still on the platform.

LIVES MAY BE LOST SEARCHING FOR SOMEONE WHO HAS GONE ONSHORE BUT WHO DID NOT SIGN OFF IN THE LOGBOOK.

Mandatory Instructions On The Platform The adherence to the following instructions is mandatory and

there shall be no relaxation of these requirements by anyone at any time.

All persons whilst on the platform shall wear as a minimum: Hard hat, safety goggles and safety boots. Other personal safety equipment such as ear protection, safety harness shall be worn as and when required.

All persons working over the side of the platform, under Cellar decks, under the bridge or on the flare boom or other exposed areas shall only do so in pairs, i.e. one man is on look out in case of accidents or incidents . Whilst working in these positions they shall wear a safety harness securely fixed to a non movable part of the structure and shall wear a life vest.

Where men are working at a height without proper scaffolding they shall wear a safety harness secured to a non-movable part of the structure. These men shall also work in pairs or have someone standing by in case of accidents.

Mandatory Instructions On The Platform

During crane operations the operator shall be directed at all times by the rigging foreman or a person designated by him. For greater safety radio communication shall be set up between the crane operator and rigger in charge.

All items, loads etc. being moved by crane shall have a "tailing" rope attached to control the swing and orientation of the load. This includes the personnel basket.

Transfer of persons to and from a supply vessel and the platform shall be by personnel basket only. RIDING WITH A LOAD IS FORBIDDEN.

If a load must be lifted over the head of other persons at workstations then the rigger in charge must warn those persons before lifting the load.

Mandatory Instructions On The Platform

Smoking is not permitted on a live platform except in specific areas such as within the accommodation module.

No matches, cigarette lighters, or smoking requisites are permitted out with the smoking areas. Any person found in possession of any of these within a no smoking area shall be immediately removed from the platform and recommendation for his dismissal made to higher management.

In any event he will not be permitted to return to the platform.

Work is not permitted on a live platform without the relevant hot or cold work permit being in force.

Gamma Ray sources may not remain permanently on the platform. It must be removed as soon as possible after use.

Offshore Cranes With guidance from the crane manufacturer or a

competent person, duty holders should; review the design of their cranes to ensure they

have identified whether any single line components exist in hoisting and braking systems. Techniques such as 'failure mode effects analysis' should be employed;

where such components are identified, ensure that the maintenance and inspection activities undertaken on these components are sufficient

verify that the 'competent person' who undertakes the 'thorough examination' of the crane thoroughly examines the hoisting and braking systems

Offshore Cranes

Verify that the 'competent person' who undertakes the 'thorough examination' of the crane thoroughly examines the hoisting and braking systems

ensure the scope of the thorough examination, the scope of the inspection scheme and the maintenance activities relating to all hoisting and braking systems (e.g testing, inspection, component replacement intervals etc)

Offshore Helidecks The net needs to be strong enough to support the

weight of any person who may inadvertently stand on it;

The offshore standards ( CAP) increased the drop test weight from 75 kg to 100 kg (dropped from a height of 1 m);

the adequacy of examination and test procedures to identify possible corrosion and deterioration of the whole of the net, its attachments and supports due to wear and tear, weathering, ageing etc (BS EN ISO 9554:2005 provides guidance on discard criteria);

ensure a suitable net replacement schedule is in place.

EMERGENCIES

Main Concerns during major accidents Pool fires BLEVE ( Shutdown , Isolation , Activation of

fire cooling and extinguishing systems and evacuation )

Jet fires Un-Ignited gas release or H2S Gas cloud

EMERGENCIES Emergencies come under the following headings

and descriptions. LOCAL EMERGENCIES ( Level 0 ) A local emergency can be a small fire that does

not threaten life or damage to the platform but people must be alerted to stay out of that area till the emergency is over.

GENERAL EMERGENCY ( Level 1 & 2 ) A general emergency is a situation where there is

a possibility of danger to lives but not to such a degree that evacuation may be required.

However, this may call for the crew to standby at their muster station and await instructions. Everyone must wear a life jacket

EMERGENCIESEMERGENCY EVACUATION ( Level 3 )

An emergency evacuation is a situation where there is imminent danger to life and damage to the platform. This could be caused by a fire getting out of control, an explosion or a wellhead blow out where everyone must evacuate the platform as quickly as possible.

However, this must be done in an orderly manner to avoid panic and injury to personnel.

Where there is time and the loudspeaker system is operating and manned then the following instructions will be given in Arabic and English.

a.Go to your muster station. b.Launch life rafts. c.Take to the rafts.

EMERGENCIES There must be a responsible person nominated to be in

charge of each life raft who shall activate these instructions. He will be in command of the raft and personnel until rescued.

Where the loudspeaker system is not operational and only the abandon ship signal is given everyone will go to their muster station and the person in charge of the life raft will be responsible for getting his crew off the platform.

When everyone is on board the life raft the rope attaching it to the platform must be cut to allow the raft to drift free.

Once the raft is clear of danger from the platform the sea anchor that must be launched, which will keep the raft on station till help arrives.

There is other SOLAS (Safety of Life at Sea) equipment in the raft and the person in charge must ensure that these are used properly

Man Over Board ( MOB )

A major concern of maritime A major concern of maritime operations is recovering operations is recovering personnel who have fallen personnel who have fallen overboard and safely overboard and safely transferring them from the transferring them from the water to the deck of a boat or water to the deck of a boat or hatch of a lifeboat.

LOCKOUT AND TAGOUT PROCEDURESLOCKOUT AND TAGOUT PROCEDURES

Step 1Step 1: : Preparation and notificationPreparation and notification Before servicing or installing equipment , you must be able to answer Before servicing or installing equipment , you must be able to answer

the followingthe following questions :questions : -- What is the type of energy source on the equipment ?What is the type of energy source on the equipment ? -- What are the potential hazards related to the energy source?What are the potential hazards related to the energy source? -- What steps are necessary to control the energy source?What steps are necessary to control the energy source? -- Who needs to be notified that the equipment will be shutdown Who needs to be notified that the equipment will be shutdown

for service?for service? Once these questions have been answered notify all affected Once these questions have been answered notify all affected

employees that a lockout procedure is about to being (and that the employees that a lockout procedure is about to being (and that the equipment will be) shutdown for service.equipment will be) shutdown for service.


Step 2: Shutdown the equipment : Follow work procedure and/or

manufacturer's instruction for shutdown. be aware that some equipment has special shutdown procedures (e.g. computer controlled equipment) make sure all energy sources have been located and shutdown (some machines have more than one power source all must be shut down).


Step 3: ISOLATE THE EQUIPMENT Equipment should be isolated by : Shutting of the main breaker or control switch . Closing valves Disconnecting process lines Pulling plugs

Note : for complex machines or equipment , refer to manufacturer's control diagram

detailing the locations of all isolation points , including breaker panels , switches , valves, ..etc.


Step 4: Attach the lock and tag

Each authorized employee who is performing maintenance is responsible to inform lockout and tag out authority for locking and tagging the equipment.

Each employee whose duties require them to work on equipment must provided with their own lock and key. If more than one employee is involved in maintenance, multiple locking devices must be used to allow each maintenance employee to lock and tag. This prevents one employee from accidentally starting up the equipment while another employee is still working.


Step 5: Release any stored energy

After locking and tagging equipment, you must make sure that any stored energy on the equipment is released this is done by :

Inspecting equipment to make sure all parts have stopped moving. Bleeding electrical capacitance (stored charge).

Venting or isolating pressure or hydraulic lines from the work area, leaving vent valves open.

Draining tanks and valves.

LOCKOUT AND TAGOUT PROCEDURESLOCKOUT AND TAGOUT PROCEDURESStep 6 : Test equipment to verify that all energy has been

released and controlled:

To make sure that all kinetic and stored energy has been released or controlled , you must :

Clear personnel from danger area. Test the start switches on the equipment to confirm that all

power sources have been shutdown and switches can't be moved to the "on " or " start" position.

Secure all blocks, clamps, chains and cribs. Secure blanks and make sure they are not leaking. Check electrical circuits to make sure that voltage is at

zero. Once you have confirmed that all energy sources have

been controlled and locks and tags are in place, it is safe to begin the maintenance work.

Hydrogen Sulphide Characteristics:

Hydrogen Sulfide (H2S) is a colorless gas that smells like rotten eggs.

Hydrogen sulphide is called ” sewer gas”

hydrogen sulfide is highly poisonous.

It is found in petroleum and natural gas and sometimes present in ground water.

AT the LEL point, 100% will show on the gas monitor. This tells you that you are in the explosive range of the gas. The range of methane gas is from 5% to 15%. H2S gas has a range of 4.3% to 44%. If the concentration is below the LEL the mixture is to lean to burn, if it is above the UEL it is to rich to burn.

Health Effects:

Hydrogen Sulphide is a potent chemical asphyxiant,

combining with hemoglobin and thus rapidly stopping

oxygen from access to cellular metabolism (just like gases

such as carbon monoxide and hydrogen cyanide). Indeed

H2S is arguably as toxic as Hydrogen Cyanide HCN.

Hydrogen Sulphide very foul smells but very quickly

paralyses the sense of smell, and can go on to overcome

the victim and eventually cause death

Hydrogen Sulphide is also an irritant of mucous

membranes including the eyes and respiratory tract


How Hydrogen Sulphide is Formed? Hydrogen sulphide is formed as a result of decomposing animal

manure.

Properties of Hydrogen Sulphide:

• Colorless gas

• “Rotten-egg” odor (low concentration less than 1 ppm).

• Approximately 20 % percent heavier than air, with a specific

gravity of 1.19.

• In concentrations of 150 ppm or greater ,the ability to smell the

gas is lost instantaneously and relying on sense of smell is

very dangerous.

Radar Video Surveillance (RVS) Radar Video Surveillance (RVS) is a key element in

guarding against potential attacks

RVS provides 24/7 vigilance that is not dependent on humans, while enabling early detection and advance warning of approaching vessels within the Area Of Interest (AOI). This allows personnel to implement countermeasures such as:

Sound alarms on the platform Alert the company and other counter-threat support (on-

shore, Coast Guard, etc.) Illuminate the platform and the suspected craft Initiate other response procedures

Security CCTV cameras for platform monitoring

Security CCTV cameras have two important roles in an overall security plan for an offshore platform. The first role is assessing any detected alarm and validating the root cause of that alarm. The second role is that surveillance.

Platform owners/operators should consider providing CCTV camera coverage for the following areas:

Main accesses to the platform structure Vulnerable and critical areas not under direct supervision Radio room IT main server room Main electrical room Access points between decks

Hazards Of Pressure TestingHazards Of Pressure Testing

Hot BoltingHot bolting is defined as the sequential removal and

replacement of flange bolts and nuts, one at a time, on piping or process systems containing pressurized fluids (i.e., oil, water, gas, air, etc.).

Precautions: Make sure the following conditions are met (or are not

applicable) before proceeding: The flange to be “hot bolted” must have a minimum of

eight (8) bolts. The operating pressure must be less that 75% of the

maximum allowable working pressure (MAWP) of the piping or process system to be hot bolted. For example, if the MAWP is 1440 PSI, the operating pressure must be less than 1080 PSI (1440 x .75).

The process temperature must be between 0F and 160F.

Hot Bolting

Hot Bolting- Precautions All flanges and associated system equipment must be

adequately supported and not subject to excessive vibration, pulsation, or shock/impact loading.

The gasket area must not show signs of leakage and the piping, flanges, and bolts and nuts must not be significantly corroded (i.e., to the point of affecting the integrity of the metal).

Existing flange bolts/nuts must be the correct size and grade and must be tight.

No simultaneous hot work operations are being conducted in the near vicinity; a leak may develop during hot bolting.

The proper tools and materials needed to complete the work are available and in good condition: properly-sized hammer wrenches and hammer; properly-sized bolts and nuts.

Hot Bolting - Precautions

Use gas detector to sniff our area to ensure gas-free before hammer-striking wrenches.

Know that hammer-striking may result in flying fragments. Know that all personnel must be aware of and stay alert to hammer-

swinging. If air saws required for procedure, complete “non-welding hot work

permit”. If possible for someone to walk under work site, install caution tape

to prevent entry. Place pollution protection under work site; leaks may occur from

flange. Communicate with other contract personnel; communicate what you

are doing and identify what they are doing. If applicable, check fuel and oil in air compressor to ensure it will not

stop or be damaged during procedure. Ensure air hoses are out of walkways and work areas; use pins and

whip checks if needed.

Hot Bolting Procedure

Procedure:1.0 Verify ALL conditions identified in “Precautions”

section are met (or are not applicable); if ANY not met, STOP and add necessary steps to JSA to make process safe.

CAUTION : Wipe hammer handle if wet or contains foreign material. If possible, use mechanical device to hold wrench when striking with hammer. Keep fingers and hands out of the way. Wear gloves, safety glasses at all times.


2.0 Using proper sequence from diagram below, – carefully and safely loosen one nut on first bolt using

hammers and hammer wrenches, – use impact wrench to complete removal of nuts, – use hammer to beat bolt out; if necessary, use cold

cut saw to cut bolt to complete removal, and– replace new bolt and nuts and carefully and safely

tighten nuts using impact wrench and/or hammers and hammer wrenches.


3.0 Carefully and safely repeat step #2 until all old bolts/nuts are replaced with new ones.

CAUTION Maintain communications with the customer representative regarding “precautions”; if a significant change occurs or leaks are detected, STOP the “hot bolting” process; correct all unsafe conditions before continuing.

4.0 Once all bolts and nuts are replaced, conduct final tightening following same number sequence.

NOTE If leak develops and absorbent pads are used to collect liquids, properly dispose in DOT drums. Place all scrap iron into scrap iron basket and all paper and plastic waste in trash dumpster.

5.0 Pick up the tools and materials and return them to their proper storage locations. Leave the work area cleaner than you found it.
