The Situation

You are the staff electro-technical officer on a large cruise ship at sea. A passenger lift was repaired overnight and needs testing. This scenario takes you through the whole task from start to finish: the plan, the risk assessment review, the permit to work, the job site review and the job itself. Your earlier choices carry forward.

The Lesson

The controls are a chain: scope the task, test the risk assessment against the real equipment, build a scope-change trigger into the permit, brief and check the site, and stop the moment the task moves. Positive isolation, not interlocks.

Human Element

A task that began as a car test and became a shaft entry from another deck, with a known door-release defect treated as a nuisance, self-resetting interlocks relied on as a barrier, a stored call that moved the lift, and a permit that did not notice the scope had changed.

Try the First Decision

PLANNING AND PREPARATION. You are the staff electro-technical officer (SETO) on a large cruise ship at sea, early in the morning. A passenger lift was repaired overnight and has to be tested before it goes back into service. An electrical technician will work with you. You know the release key for the deck 12 shaft doors is defective. You are writing the plan for the test.

A. Plan it as a test from inside the car only. State that nobody enters the shaft, the car top or the pit under this plan. Treat the defective deck 12 door release as a defect to fix first, and decide now how any shaft access would be done later, with the lift isolated.
B. Plan it as ‘test lift after repair’ and sort out access as it comes up. The technician knows the lift.
