Define the systems

Prepare access information
Provide relevant drawings, ceiling or access-panel locations, restricted areas and any onboard authorization requirements.
Confirm the working window
Share port or marina, berth details, planned arrival and departure, and whether the vessel will be occupied.
Agree the handover
Discuss photographs, serviced-area records and any verification requirements before work begins.
