Minimise vessel downtime and off-hire

Taking a vessel into dry dock to perform critical repairs or planned refurbishment costs time and money. With Trident Underwater services, the work can be performed below the waterline by specialist diver technicians during scheduled port calls. This reduces both maintenance costs and downtime while minimising the impact on your vessel’s operation.

Trident Underwater services cover the underwater repair, refurbishment and maintenance of vessel machinery and equipment as well as the propulsion system, seals and hull, based on a thorough underwater assessment by our specialist teams of certified experts.

Underwater repairs and upgrades save time and money by avoiding the need to dry dock a vessel

    Propeller systems

    We can evaluate the condition of your vessel’s propeller from below the waterline and recommend the optimal repair or refurbishment solution based on our in-depth knowledge of hydrodynamics. Our solutions for propellers include blade straightening and repair of damaged sections, trailing and leading-edge modification, and diameter and blade-area reduction. We can also install energy-saving devices such as the Wärtsilä EnergoProFin.
