During departure, with the vessel partly swung off the berth using a spring and engine power, the engine fails to respond to a manoeuvring order (no thrust change despite the telegraph order). What is the immediate priority?

A. Assume the engine fault is minor and continue the departure exactly as planned, expecting it to resolve itself

B. Repeat the same engine order multiple times and wait, without informing anyone else on the bridge or escalating

C. Immediately inform the pilot/Master of the engine non-response, assess the vessel's current trajectory and what is holding or moving it (wind, current, remaining lines, tugs), and take whatever action is available (additional tug assistance, anchor, fenders) to regain control rather than assuming the engine will respond on a subsequent order

D. Immediately abandon the conning position without handover or communication to deal with the engine personally

A. Accept the new plan without question since the pilot has local knowledge and authority over all manoeuvring decisions

B. Insist on the original MPX plan being followed exactly regardless of the pilot's reasoning

C. Query the change directly and ask the pilot to explain the reasoning before accepting it — the pilot brings essential local knowledge, but the Master retains overall responsibility for the vessel and must understand and be satisfied with the plan being followed, not simply defer without comprehension

D. Say nothing and monitor passively, since pilots are never required to explain their plan to the Master

A. Speak up immediately and clearly, stating the specific observed hazard — the presence of a pilot does not remove the bridge team's obligation to maintain independent monitoring and to challenge anything that appears unsafe, regardless of the pilot's experience or authority on the bridge

B. Wait for the Master to notice independently before raising any concern

C. Say nothing, since the pilot is in charge of conning the vessel and has ultimate authority over the navigation

D. Only raise the concern after the vessel has already entered the shallow water, to avoid questioning the pilot prematurely
