Underwater stern tube seal renewal is a critical service for maintaining the performance and environmental compliance of marine propulsion systems. At Dive Marine Services, we specialise in underwater shaft seal replacement using our innovative flexible habitat system. This advanced technology allows our technicians to perform complete seal overhauls below the waterline, eliminating the need for dry docking and significantly reducing vessel downtime and operational costs by performing this vessel during cargo ops.

Our flexible habitat is uniquely designed to adapt to the stern tube area of any vessel, whether it’s a commercial cargo ship, offshore support vessel, or luxury yacht. It creates a sealed, dry working chamber around the stern tube while the vessel remains afloat, enabling safe and efficient underwater seal replacement. This method supports all major shaft seal types, including lip seals, face seals, and air seals, from leading Original Equipment Manufacturers (OEM).

By choosing underwater stern tube seal renewal, shipowners benefit from faster turnaround times, lower maintenance costs, and reduced environmental risk. Our highly trained dive teams carry out the work in cooperation with the OEM, ensuring long-lasting performance and compliance.
