Action to be taken during Man Overboard Situation (Video Lesson)
The initial and early sighting of the fallen crew plays a vital role in increasing the percentage of saving their life. The actions for a MOB mentioned below are extremely urgent and must be taken without delay to save the life of the person who has fallen overboard.
Shout ‘Man Overboard on Starboard side/Portside’.
Change over to hand steering from auto and put the wheel hard over to the respective side (port or starboard).
Release the MOB marker from the side of the bridge wing to which MOB has occurred. This marker is buoyant and has a self-igniting light and self-activating smoke signal.
Press the MOB button on the GPS to mark the casualty’s position for future reference.
Sound’ O’ on the whistle (Three prolonged blasts). This is to let the Master and the crew know about the emergency. Supplement this with the appropriate ‘O’ flag.
Post an extra lookout as soon as possible.
Sound the General Alarm on the ship’s whistle to alert everybody to proceed to stations. This is to ensure that if the crew has not understood the three prolonged blasts for MOB, they are alerted regardless and proceed to muster stations to assist in the recovery of the person.
Thereafter, announce the MOB situation on the ship’s PA system.
Inform the engine room of the situation that maneuvering will be required.
Execute the Williamson turn (explained later).
Keep a keen eye on the RADAR/ARPA and put the VHF on Channel 16.
Maintain a record of all the events in the Bell book.
Carry out Master’s orders.
The Chief Mate should take over all decisions based on deck, about lowering survival craft, boarding ladder, etc.
The Third Mate ought to assist the Master on Bridge.
The officer in charge at the moment must send out an “Urgency signal” on all the communications systems to let ships in the vicinity know about the situation.
Keep the lifebuoy (MOB marker) in sight.
The rescue boat should be manned adequately to carry out the rescue operation. Everyone should wear a personal location beacon.
The officer in the rescue boat must carry a portable handheld VHF
Once the person is rescued, the rescue boat must be picked up upon arrival close to the ship along with the lifebuoy and hoisted back.
Immediate first aid should be administered if required.
An ‘Urgency Signal’ must be sent out to cancel the last transmitted MOB alert.
Appropriate entries must be made in the Ship’s Logbook.
The Master must conduct an inquiry concerning the MOB incident and all entries made in the Ship’s Logbook.
The engines are not stopped immediately to keep the person away from the propeller. The same is the case for wheeling hard over to the casualty’s side as it is done to keep the stern away from the casualty.
