A Member has reported the following incident which occurred onboard one of its vessels.
What happened?
The vessel was sailing in 6 - 8ft swell and 35kts wind speed, when it was noticed that one of the accommodation cabins was flooding with water. Upon opening the cabin door, it was noticed that water was entering the cabin from an open porthole.
The duty seaman immediately switched off the power supply to the accommodation cabins in order to prevent any short circuiting of the electrical system and possible fire. He also closed the porthole immediately.
The company’s basic sailing procedures require that ‘all portholes be securely closed when sailing’ irrespective of the weather conditions. This procedure was not followed.
The company has issued a reminder as follows:
