During emergencies, the muster list specifies where fire and abandon ship stations are and what duties each person has. This document is the official roster that assigns crew to specific muster stations, fire parties, and abandon-ship roles, ensuring a clear, organized, and coordinated response during drills and real events. It also indicates reporting paths and responsibilities, so everyone knows exactly who does what and where to go when the alarm sounds. The radio room houses communications procedures and the radio operator’s tasks, not the full set of emergency station assignments. The engine room notes cover engine operations and engineer on-duty duties, not the ship’s muster locations for firefighting or abandoning ship. The watch bill shows who is on watch, but it does not designate emergency stations and duties for fire or abandon-ship procedures.

The SOLAS Convention was developed by the International Maritime Organization, the United Nations’ specialized agency charged with maritime safety and security. SOLAS sets the minimum safety standards for ships, covering areas like lifesaving appliances, firefighting, navigation, and structural integrity. The IMO drafts and updates these rules through international conferences and amendments, and member states implement them in national laws. While the UN provides the broader framework, SOLAS specifically comes from the IMO. Other organizations like the WTO and ILO deal with trade and labor issues, respectively, and are not the bodies that created SOLAS.

Approval of the operating instructions for rescue boats and liferafts is handled by the vessel’s administering authority, i.e., the flag state, to ensure they comply with SOLAS and match the approved equipment. On OSVs under many jurisdictions, that administering authority is the Coast Guard, which reviews and issues approval for the launch, operation, maintenance, and safety precautions described in the instructions. The Master uses these approved instructions, but does not grant the approval itself. The Port Authority doesn’t have this approving role, and while the Flag State is the broader entity, the Coast Guard is the specific administering authority in this context.

Redundancy and full evacuation capability from any single location is the idea here. On a MODU with lifeboats in two different places, if one location is lost, the lifeboats that remain must still be able to carry everyone on board. That means the surviving boats must be able to accommodate 100% of the personnel. The other options would leave some individuals without a lifeboat if one location were unavailable, which isn’t acceptable for safe evacuation planning.
