Flooding

On rare occasions, seamen also experience a flooded engine room, which may seriously affect the vessel’s stability and buoyancy, and obviously the mechanical and electronic equipment located there. There is a range of possible scenarios here, and thus we will offer advice on what may be considered banal.

The remedy for flooding by seawater is simple and basic: flush with freshwater, dry, clean and preserve. Again, you should seek advice from owners/managers .

The ISS has kindly allowed us to refer to their list of action for the crew, this time in case of seawater damage or flooding:

 

Marine Damage Control
Electronics – Electrical – Machinery

First aid following seawater damage can be carried out by the ship crew.

  What to do Action
Step 1 Switch off all power Disconnect power for all involved equipment and machinery.
Step 2 Get an overview What has been damaged?
Keep it drowned.
Step 3 Damage control Make a good plan, apply manpower and the right working equipment.
Open up equipment and machinery, prepare for first aid. Do not let it dry.
Step 4 Action, preservation
and drying
Drain or suck up all seawater.
All equipment and machinery must be hosed down with freshwater over a period of time.
If possible, use hot water.
Drain and remove the water.
Spray or drown it all with preservation oil containing corrosion inhibitors.
Put on heaters to dry.

 

Electronics – Electrical – Machinery

First aid on drowned machinery damage can be carried out by ship crew. 

  What to do Action
Step 1 Drain and flush machinery Drain the engine of all oil and water.
Do not let it dry.
Flush down the engine inside and outside with freshwater.
If possible. use hot water-
Step 2 Electronics Open up all electronic boxes and hose them down.
Preserve all with water-removing oil and let dry.
Step 3 Damage Control Fill engine up with diesel fuel and when possible – turn engine.
Step 4 Action Drain engine for diesel fuel.
Fill with motor oil to normal level.
Check electronics and start engine.
