A cadet is asked why overside work can't be done while the ship is moving, even in calm water. What's the core reason?

A. The restriction exists mainly to protect the paintwork from uneven application

B. Calm water actually makes overside work while underway acceptable, provided speed is kept low

C. Even calm water doesn't remove the risk of someone going overboard while the vessel is making way — proximity to the propeller/rudder and the difficulty of immediate recovery are the real hazards, not sea state

D. The restriction only applies to vessels longer than 100 metres

A. There is no fixed maximum — it depends entirely on the job

B. 48 hours, renewable once without re-inspection

C. 7 days, matching the standard watch rotation

D. 24 hours from issue, with any shorter job-specific time limits also stated on the permit

A. Check elapsed time against the 24-hour limit, recognise it's close to expiry, and flag to the authorising officer that revalidation will be needed rather than letting it lapse unnoticed

B. Cancel the job immediately without consulting the authorising officer

C. Wait until the 24-hour mark is actually reached before mentioning anything

D. Accept the outgoing OOW's assessment and take no further action since the job scope hasn't changed
