At Dive Marine Services, we specialise in underwater thruster repair services that keep your vessel operating efficiently and safely. Whether you’re working with tunnel thrusters, azimuth thrusters, or azipod thrusters, our team offers tailored solutions to minimise downtime and maximise performance. We provide both full thruster replacements and targeted in-situ repairs, depending on the scope and nature of the issue.
Thruster Repair Methods
We offer two primary approaches to thruster maintenance:
Full Thruster Removal and Replacement
For extensive repairs or overhauls, we remove the entire thruster unit and install a refurbished or spare unit to restore propulsion quickly. The removed unit is then fully serviced at our specialised facilities. This method is ideal for major mechanical issues or when spare units are available for rapid turnaround.
In-Situ Repairs Using Dry Enclosures
When only a specific part of the thruster requires attention, we create a dry working environment around the affected area using cofferdams or custom-built enclosures. This allows us to repair or replace seals, bearings, and mechanical components without removing the entire unit. In-situ repairs reduce operational disruption and eliminate the need for dry-docking.

Thruster Types We Service
Tunnel Thrusters
Tunnel thrusters are transverse propulsion units located at the bow or stern, used for precise maneuvering during docking or low-speed navigation.
Common issues include:
- Shaft seal renewal
- Blade seal renewal
- Outboard box repair/replacement
- Propeller or blade replacements
Azimuth Thrusters
Azimuth thrusters are steerable propulsion units capable of 360° rotation, offering both thrust and directional control. They are essential for dynamic positioning and offshore operations.
Common issues include:
- Shaft seal renewal
- Blade seal renewal
- Hydraulic repairs
- Propeller or blade replacement
Azipod Thrusters
Azipod thrusters are podded propulsion systems with an integrated motor and propeller, offering high maneuverability and fuel efficiency.
Common issues include:
- Shaft seal renewal
- Propeller replacement
- Slewing seal repairs
