Sea chest gratings: what to include in an inspection and cleaning request

A request for sea chest grating cleaning should identify the specific areas of the hull involved. State which external gratings need inspection or cleaning. If the request also covers the sea chest itself or internal valves and fittings, list those tasks separately so their scope and feasibility can be clarified.

Vessel details to provide

Include the vessel's name, IMO number if assigned, principal dimensions and current draught. Specify the port, berth or anchorage. If the exact location is not yet known, say so: access and mobilisation arrangements will need to be confirmed for the work site.

Attach an available drawing showing the grating locations, or another document the technical team uses to identify the relevant areas. Indicate the side of the vessel, the location and the number of gratings. Add their dimensions if these are available in the documentation. If several areas are involved, list them using the same labels as on the drawing.

How to describe the task

Share the crew's observations and any available photographs. List the work required: inspection, cleaning of specific gratings, and photographic or video records of the results. The scope will be refined according to the condition of the components and the access arrangements.

List the crew's observations separately from the technical team's questions. This makes it clear which signs have already been noted and what the inspection needs to establish.

Timing and deliverables to agree

Provide the proposed working window and contact details for the agent or another responsible representative. The vessel's time in port and the time available for the work should be discussed separately. For a vessel at anchor, transport of the team to the vessel also needs to be clarified.

Specify the required deliverables: photographs before and after the work, video footage, identification of the areas inspected, or a description of observations. State any requirements for additional measurements and documentation in advance. When preparing for work near water intakes, the arrangements for safely isolating the associated systems must be agreed with those responsible for the vessel and the diving operations. Provide a contact in the technical team who can discuss these arrangements.
