Sea Chest Cleaning

Sea chests play a critical role in supplying seawater to essential vessel systems, especially cooling systems. Marine growth, shells, sediment and other deposits can restrict seawater flow through sea chest openings and gratings, reducing cooling efficiency and increasing the risk of overheating.

Restricted seawater intake can also limit the vessel’s ability to operate safely at higher engine loads and RPM. Our divers provide underwater sea chest cleaning to help restore proper seawater flow, support effective cooling and reduce the risk of overheating-related performance limitations.

Depending on the vessel’s preference and operational requirements, cleaning can be carried out either by opening the sea chest covers for a more complete internal cleaning or by performing external cleaning of the gratings and accessible surfaces without removing the covers.

A Flexible Approach To Sea Chest Cleaning

Before the operation, the condition of the sea chest, gratings and surrounding area is assessed to determine the most suitable cleaning method. If requested by the vessel, the sea chest covers can be opened to allow more extensive cleaning of accessible internal surfaces and removal of accumulated marine growth and deposits.

Where opening the covers is not required, our divers can carry out controlled external cleaning from outside. The selected method is based on fouling condition, vessel preference and operational requirements, with the aim of improving seawater intake and supporting reliable cooling performance.
