Your examiner asks: "Why does SOLAS Chapter IV not simply rely on a single method of transmitting a ship-to-shore distress alert?"

A. SOLAS IV requires that every ship, while at sea, be capable of transmitting a ship-to-shore distress alert by AT LEAST TWO SEPARATE AND INDEPENDENT MEANS, each using a DIFFERENT radiocommunication service — for example, a satellite EPIRB (Cospas-Sarsat) combined with DSC alerting via VHF/MF/HF, or a satellite terminal (such as Inmarsat) distress function combined with DSC. This deliberate redundancy exists because any single method could fail or be unavailable at the critical moment (equipment fault, the specific radiocommunication service being out of range or down, or the ship's main system being damaged in the very casualty causing the distress) — GMDSS is built around eliminating single points of failure in distress alerting, which is precisely why sea-area equipment carriage tables typically specify more than one distress-alerting method.

B. SOLAS IV requires only ONE method of distress alerting; carrying a second, independent means is a purely voluntary enhancement with no regulatory basis.

C. The requirement for two independent means applies only to passenger ships; cargo ships are permitted to rely on a single distress alerting method under all circumstances.

D. Both required distress-alerting means must use the SAME radiocommunication service (e.g. two separate VHF DSC sets), rather than two DIFFERENT services, under SOLAS IV.

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

B. Testing should wait until cargo operations begin

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

B. The lunch schedule for the deck team

C. Only the weather forecast for the next watch

D. The cargo manifest for the next port
