A cargo vessel is preparing a loading condition for review. A classroom planning worksheet gives displacement as 2,000 tonnes and a free surface moment of 160 tonne-metres for one slack rectangular tank. Its uncorrected initial GM is 0.60 metres. Another officer has calculated the correction and wants to label the entire loading condition approved because the remaining GM is positive.

During a routine cargo-space check, a worker is found unresponsive inside an enclosed compartment. The approaching crew member can see the person from the access opening but does not know the atmosphere readings or whether the space was prepared for entry. A portable light remains on inside, which tempts another person to assume that the air must be safe. The bridge receives a brief report while the vessel is underway.

Some cargo spaces are still being prepared, and the team has not yet confirmed that the vessel meets the actual contractual readiness condition. A message from the agent says that the berth may become available shortly, but it does not amend the charter terms.
