Going below and beyond

Wӓrtsilӓ Underwater Services (formerly Trident) started its journey in September 1993 as an underwater service provider with a team of two divers, specialising in repairing, overhauling and servicing seagoing vessels, marine installations and rigs for the commercial, energy and navy markets. 

Since then, it has established a far-reaching partner network of factory-trained, industry-certified diver technicians operating on a global scale, as well as a number of offices across Europe. 

That, combined with its industry-specific product training programmes and access to Original Equipment Manufacturer (OEM) products and solutions, position it to offer technical maritime support and solutions when customers need it most, while guaranteeing a high standard of service and commercial diving equipment.

Its innovative approach, outside-the-box thinking and ability to handle warrantee claims have proven invaluable to customers, which is why Wӓrtsilӓ Underwater Services is considered the OEM’s underwater service provider of choice.

    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.
