Major disaster related to oil pollution

Reasons For the cause of the major disaster related to oil pollution.
Describe the precaution for each reason.
A. Fire
B. Oil Spill
C. Collision
D  Flooding
E  Grounding



A. In Event of Fire

In Engine Room
Raise the alarm
If the fire is minor, restrict the spread and use the nearest appropriate fire extinguisher.
In case of Major fire, follow Fire plan on board.
Muster at Emergency Headquarters.
Carry out duties, as assigned and report to Senior officer present. This includes:
a) Sealing off Engine Room by shutting all doors, ventilations, sky light and other points of access.
b) Ensure by a Head count, that all personnel are accounted for.
c) Quick closing valves, Trips for purifiers and all fuel transfer pumps are operated.
Chief engineer, in consultation with the Master, will release CO2 to Engine Room.

Outside the Machinery Spaces
Raise the alarm.
Determine the location of the fire.
Check for oil/hazardous substances, pollution and its possibility and ways to restrict the spread of the fire.
Located any causalities and provide First Aid.
Contain and extinguish the fire (use appropriate fixed fire fighting system).
Emergency Distress transmitter to be set up by ship and kept ready for usage.
If the Vessel is in port - stop cargo work, evacuate shore personnel, keep the Main engine ready on short notice. Inform the

local Fire Brigade and Coast Guard services.
All vessel's movement and events recorded.
The fire fighting plan provides for various group to be assigned specific duties. Attack Party, Back-up Party, Technical

Party and Control Party.


B. In the even of an Oil Spill

This could a rise during Bunkering operations, oil transfers, tank overflows, cargo oil tank or fuel tank leakage due to

damage.
Stop the fuel transfer operation immediately and raise the alarm.
Activate the Oil Spill Contingency plan.
Oil fired galley, if running to be stopped.
The source of the oil spill must be identified, and actions taken to restrict the spread of oil.
Consider draining the split oil into slack cargo tank or slop tanks.
Suspend operations, until leak rectified/isolated.
Clean up affected area.
Use oil spill dispersant and recover as much oil as possible using oil absorbents.

As any Emergency involves liability, compensation and legal issues, a comprehensive log of events and all communications must

be recorded.


C. In the event of a Collision
Main Engine must be stop.
Emergency Alarm raise by Duty Officer.
Manned the Engine Room (in case of UMS vessels).
Investigate and record damage, especially due to ingress of water in Engine room and any equipment which is affected.
Take the required steps for fire fighting, in case of fire.
Closely monitor all tank sounding and confirm if all double bottom tanks are intact/have been damaged.
Check for oil pollution on sea surface immediately around and in the vicinity of the vessel and report.
Check electrical switchboard for foults, e.g low insulation.
Status of Main Engine and auxiliary equipment to be reported to bridge.
Assess immediate danger e.g. possibility of sinking, capsizing or flooding.
Carry out damage control and temporary repairs and report.

The designated Person, who may be the Superintendent, must be informed and follow his instructions. Master will inform Port

Authorities and arrange for the P&I surveyor.


D. I n the even of Flooding

Flooding of the Machinery spaces
If the vessel is at sea, slow down Main Engine and raise Emergency Alarm.
Use Emergency Bilge Injection valve.
Locate and isolate cause, and stop the ingress of water, if possible.
In case of severe leakage, main sea suction valve may have to be shut, which will involve a shut-down of the Generators

(black out), during which repairs must be done.

Flooding of compartments or tanks outside Machinery spaces.
Slow down/stop main engine and raise Emergency Alarm.
Attend E/R services and control, inform Bridge of the status of the main engine and auxiliaries.
Locate any casualties and render first aid.
Check sea surface around for possibility of pollution.
Closely monitor all tank sounding and confirm if all double bottom tanks are intact/have been damaged.
Assess immediate danger e.g. possibility of sinking, capsizing or flooding.
 In case the situation is out of control,
a) Distress Message must be sent from vessel.
b) Follow the procedure of Abandon ship.


In case the situation is brought under control.
a) Initiate Damage control measures, check stability criteria.
b) Assess damage and report to the Superintendent.
c) Unsure cargo is intact.


E. In the event of Grounding
Stop Main Engine. Raise Emergency Alarm.
Attend E/R services and control, inform Bridge of the status of Engine room and Auxiliaries.
Change over to high sea suction.
Closely monitor all tank sounding and confirm if all double bottom tanks are intact/have been damaged.
Assess immediate danger e.g. possibility of sinking, capsizing or flooding.
Check for oil pollution.
Status of main engine to be recorded, which all will include.
a) Crankcase Inspection (check of running gear in details)
b) Crankcase Deflections.
c) Stern tube condition, and oil leak if any.
Steering Gear to be check.
Auxiliary equipment to be check.
May required to clean all sea water cooler/exchangers on the sea water side.
