Wärtsilä Underwater Services

Wärtsilä 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 warranty claims have proven

invaluable to customers, which is why Wärtsilä Underwater Services is considered the OEM’s

underwater service provider of choice.

Our specialist teams of certified diver technicians and propulsion experts serve you around the clock, and can be dispatched in a matter of hours.

Wherever in the world your vessel is, we can provide fast-response and class-approved repairs as well as inspections, refurbishment and equipment installation or replacement.

We advise vessel owners and classification societies on the most optimal and cost-effective repair and refurbishment solutions based on a thorough underwater assessment of the equipment or systems in question.

Our methods not only meet the requirements set out by manufacturers and classification societies, they are also safe for the environment.
