Underwater Shaft Seal Repairs and Habitat Services in Rotterdam, Amsterdam, Antwerp and Worldwide

Underwater Shaft Seal Replacement and Repairs While Afloat

5 Oceans Diving specializes in underwater shaft seal repairs, replacements and habitat installations for vessels operating worldwide. Our experienced commercial divers and technicians perform complex shaft seal overhauls while the vessel remains afloat, eliminating the need for dry docking and significantly reducing downtime and operational costs.

Operating 24/7 in the ports of Rotterdam, Amsterdam, Vlissingen, Antwerp, Ghent, Zeebrugge, Le Havre, Hamburg and Bremerhaven, our teams are also available for worldwide mobilization to anchorages, terminals and offshore locations.

Through years of development, 5 Oceans Diving has invested in a unique habitat system specifically designed for underwater shaft seal repairs. Unlike conventional systems, our reinforced habitats are engineered to safely operate not only alongside the quay but also at offshore anchorages and exposed locations.

Our habitats are available in various sizes and can be rapidly deployed to accommodate virtually any shaft diameter.
