Dive Marine Services’ proprietary Flexible Habitat Technology has transformed the way stern tube seal renewals are carried out. The lightweight, modular system creates a controlled dry working environment around the stern tube assembly, enabling technicians to perform OEM-approved seal renewal procedures while the vessel remains afloat.

Designed for rapid worldwide mobilisation, the habitat can be adapted to accommodate a wide range of vessel types and stern tube seal configurations. By eliminating the need for dry docking, Flexible Habitat Technology provides shipowners with a safe, efficient and cost-effective alternative for completing complex underwater repairs with minimal disruption to operations.

Stern tube seals are essential to the reliable operation of a vessel’s propulsion system, preventing seawater ingress and lubricating oil leakage around the propeller shaft. When seals become worn or damaged, timely renewal is critical to maintaining operational efficiency, environmental compliance and the long-term integrity of the propulsion system.

Every stern tube seal renewal begins with a comprehensive engineering assessment of the vessel’s stern arrangement, seal configuration and operational requirements. Working closely with shipowners, Original Equipment Manufacturers (OEMs) and, where required, classification societies, Dive Marine Services develops bespoke repair methodologies tailored to each project.

Combining engineering expertise with our in-house developed Flexible Habitat Technology, our experienced repair teams are able to complete permanent underwater stern tube seal renewals safely and efficiently, helping shipowners minimise downtime, maintain operational schedules and avoid unnecessary dry dockings.
