In a SAR operation, your vessel is designated "On-Scene Coordinator" (OSC) by the coordinating rescue authority before dedicated SAR units arrive. What are the OSC's general responsibilities according to IAMSAR guidance?

A. The OSC role can only be assigned to a vessel with a qualified Master Mariner with no other vessels involved

B. The OSC is responsible for coordinating the on-scene search and rescue effort among the vessels present — this typically includes establishing communications with all participating units, organising and allocating search patterns/areas to avoid duplication or gaps, maintaining a log of the operation, liaising with the coordinating rescue authority (e.g. MRCC) and reporting progress, and handing over coordination smoothly to a dedicated SAR unit or authority when one arrives on scene

C. The OSC has no communication responsibilities; this is handled entirely by the MRCC ashore

D. The OSC's only task is to maintain position and wait for instructions, taking no coordinating role

A. Nothing — a test lift can proceed immediately after repairs

C. The area within the grab's swing radius should be cleared of personnel before the lift

D. Only the crane operator needs to be aware the lift is happening

A. Who must remain clear of the exclusion zone while the lift takes place
