OOW-3000-L3.4

Navigational and other emergencies

The examiner tests how the OOW responds when things go wrong, because the first minutes decide the outcome. This lesson covers the response to navigational emergencies, to fire and abandonment, and the distress communications that summon help.

Navigational emergencies

First actions on a grounding or collision

  1. Raise the alarm, stop or handle the engines as appropriate, and inform the Master.
  2. Sound round the vessel and assess damage and flooding; close watertight boundaries.
  3. Check for pollution and for injuries, and account for all persons on board.
  4. Fix and record the position and time and make the required reports.
  5. Take damage-control action and, if the situation warrants, initiate distress procedures under the IAMSAR Manual.

Fire and abandonment

  • Know the emergency parties, the muster list and the drills, the fire control plan, and how to isolate fuel and stop ventilation to a space.
  • Know the classes of fire and the correct extinguishing media, and the fixed and portable firefighting systems carried (covered in depth in the Advanced Fire Fighting course).
  • Know the life-saving appliances — liferafts, lifeboats, EPIRB, SART, immersion suits, the line-throwing appliance — their markings, locations and use.
  • Know the survival principles and how to launch, manage and recover survival craft, and how to account for and control passengers.
  • Abandonment is the Master's decision and a last resort, taken only when the vessel is a greater danger than the sea.

Distress communications

The OOW must be able to send and handle distress and urgency traffic through GMDSS — a DSC distress alert with position, followed by a MAYDAY by voice giving the vessel's identity, position, nature of distress, help required and number aboard — and recognise the distress signals of others. On receiving a distress, the obligation to assist under SOLAS and the search-and-rescue framework of the IAMSAR Manual apply, and the OOW acts on it and informs the Master at once.

WARNING — The first minutes decide it Raising the alarm, informing the Master and accounting for people come first, before investigation. A calm, practised drill in the first minutes of a fire or flooding is worth more than any later heroics.
