Wärtsilä Underwater Services

Wärtsilä Underwater Services

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.
