Underwater Bow and Stern Thruster Repair/Replacement

Any Bow Thruster on the current market Removed, Overhauled/Repaired Inn House and Replaced while the vessel stays operational and afloat typically within 2/3 weeks for more information contact FN Diving. Afloat propulsion repairs are performed most conveniently during cargo operations which save you downtime and the cost of docking.

If docking is not an option, bow thrusters can be repaired and exchanged afloat underwater and completely overhauled with most spares on stock for the repair.

FN Diving has all nescesary equipment in order to exchange any thruster unit on the market underwater while the vessel remains on schedule. With a special light weight tunnel blanking technique allowing dry operations for our diver technicians, thruster blades and seals can be replaced, repair work on the gearbox or another specific part of a thruster can be performed while the vessel stays operational and afloat even the complete unit can be exchanged.

These bow thruster repairs are most favorably done during normal cargo operations of the vessel. Propeller blades and seals can be replaced, repair work on the gearbox can be performed and whole units can be extracted and replaced or sent to repair in our workshop.

Under 24hrs & no drydocking

The total time for tunnel thruster removal and replacement are normally under 24 hrs, with no drydocking or down time. It’s a cost effective solution that is guaranteed to get you back on schedule fast. Feel free to contact us!
