Sea Chest Cleaning & Repair in Africa
Grating removal, internal cleaning, blanking and sea-valve support — in-water
Protect Cooling Flow. Avoid an Emergency Docking.
A fouled sea chest restricts cooling-water flow to the engines and generators, raises exhaust temperatures and can force an unscheduled docking when a strainer blocks at the worst moment. Our divers open the chest, clean the internals and restore full intake flow in the water — alongside, at anchorage or during cargo operations.
We work at 40+ African ports, mobilised from Douala in 24–72 h. Every job closes with CCTV footage of the cleaned chest and grating, delivered to your superintendent within 24 h.

Sea Valves Overhauled Without Docking
When a sea valve needs overhaul, the chest can be blanked off underwater so the valve is worked on safely from inside the ship — no dry dock, no off-hire. Divers fit the blank, stand by during the overhaul and refit the grating on completion, with a leak test before the chest is returned to service.
The same call covers grating removal and refitting, mesh replacement and clearing of blocked intakes after grounding or heavy fouling.
