BULK PROTECTOR Cargo Holds Water Ingress Monitoring & Alarm Detection System
BULK PROTECTOR Cargo Holds Water Ingress Monitoring & Alarm
Detection System Introduction SELMA Cargo Holds Water Ingress Detection System “BULK PROTECTOR” supervises
and detects Water presence in Cargo Holds Area, any Ballast Tank and any Dry/Void
Space any part of which extends forward of Foremost Cargo Hold (other than chain
locker).
The main aim of the System is to perform Detection by generating Audible & Visual
Alarm Signal by indicating the Point where the Water was detected.
In particular according to IMO Resolution MSC.145 (77) “Performance Standards for
Water Level Detectors on Bulk Carriers” and IACS Unified Interpretation (UI) SC180 the
supervision should be implemented on the following points :
Specifically in Cargo Holds Area the Alarm is performed when Water Level reaches
0.5m & 2.0m Height from inner Bottom. In Fore Peak Tank or Ballast Tank Area forward
of Collision Bulkhead, the Alarm is performed when Water Level reaches 10% of Tank
Level Capacity. In any Dry or Void Space Forward of foremost cargo hold the Alarm
Signal is performed when Water Level reaches 0.1m above Deck.
Furthermore Override Buttons are comprised in order to disable Alarm on Fore Peak
Tank, Ballast Tank forward of Collision Bulkhead and in Holds that are used as Ballast.
When the Water Level is below Alarm Set Points then automatically the Fore Peak Tank,
Ballast Tank & Ballast Hold Override function change over into Alarm Normal Operation
according to MSC.145 (77).
Finally all Alarms are performed according to IMO “ Code on Alarms and Indications
1995” refer to 3.3.2 of IMO Resolution MSC.145 (77).
BULK PROTECTOR Cargo Holds Water Ingress Monitoring & Alarm Detection System
It is worthy to be noted that R4 is the Override Function Push Button. When is pressed
then the Specific Hold is used as Ballast. It should be noted that the Display is
programmed each time to perform Ballast Mode only on the Holds which are used as
Ballast from Vessel Particular Specifications.
When the Operator press the specific Function Key and then R2 in case that is Specific

DEAD ZONE : In order to fit the Sensor Higher from inner
Bottom but not more than 0.3m, then the System should be
configured by changing the Dead Zone Parametter. In this case
if i.e. Dead Zone is 0.18m (Distance of Sensor from Hold
Bottom) then when the Water Level reaches the Sensor, in this
case the actual Value will be :
ACTUAL VALUE = (Water Level) + (Dead Zone)

Field c : Presents Spare Alarm No2 Condition “NORMAL” or “ALARM” .
Field d : Presents Spare Alarm No2 Sensor “NORMAL” or “FAILURE”
BALLAST MODE OVERRIDE FUNCTION There are Areas in Bulk Carrier that are used in several periods as Ballast. Specifically,
Fore Peak Tank and Ballast Hold/Holds that are notified on Vessel’s Technical
Specifications. Those Area’s should be in Override Operation when are in Ballast
Condition.
i.e. In case that the Operator prefers to use a Particular Hold as Ballast, then he should
proceed to the following Tasks :
- Press Function Key of the Specific Hold or Fore Peak Tank.
- Press R4 - Then automatically Override Function of the Specific Area is energized and on
Display is marked the Label “Ballast Mode”
Note 1: In case that the Operator after following this procedure forget to use the Specific
Hold as Ballast , then the program after 1 hour returns to Normal Condition of the
specific Area and reset Ballast Mode.
Note 2 : In case that the Operator follows the above procedure, and the specific area is
used as Ballast, then when the Water Level returns below lower Alarm Set Point, in
this case automatically Override Function is reset [Ballast Mode is Reset] and
Supervision of the specific Area is reactivated automatically [Normal Condition]. [According to IMO Resolution MSC.145 (77) “Performance Standards for Water Level Detectors on Bulk
Carriers” and IACS Unified Interpretation (UI) SC180]
BULK PROTECTOR Cargo Holds Water Ingress Monitoring & Alarm Detection System
PROCEDURE FOR CHANGING PARAMETERS OF SET POINTS If the Operator prefers to change one of the Parameters that are presented on Display
[Sub Pages of Parameters Pages]
s
- Press Function Key of Specific Hold or Fore Peak Tank
- Press R1 or R2 or R3 in order to observe the specific Sub Page
- Press Mode - A Number Start Flickering which illustrates that is ready for value change
- In order to pass to the next numbers press each time Mod. Then each time the
Operator press Mod he can pass to the number that he prefers to change
- When the preferred number start flickering then the Operator Type the number
he prefers from Display Keypad
- Press Enter
- New Set Point has been implemented
- Note : In order to pass each time to Sub Pages, the operator should press each
time Function Key of Prefered page and then R1 or R2 or R3. In other words if
for example he press R1 he can not press afterwards R2. He should return to
Specific Application Page by pressing specific Function Key and then press R2. The same procedure should be followed with R3. Return to Specific Application
Page by pressing specific Function Key and then R3.
