Innovative Underwater Solutions

We have underwater factory-approved repair options available, executed by trained and certified technicians. Product improvement and procedure development together with major Original Equipment Manufacturers (OEMs) allow us to provide a safe, reliable, and cost-effective underwater service.

Our in-house and external OEM training/certification programmes give underwater technicians a firm understanding of hydrodynamics, allowing them to evaluate and execute complex underwater propeller repairs. We advise owners and classification societies on the best propulsion and cost-effective repair solutions on-site, based on our initial underwater examination.

Our extensive experience acquired over the decades allows us to engineer and build innovative tools and equipment for underwater propeller repair solutions beyond existing methods. This means more economic, time-saving, and technically advanced propeller modifications and repair solutions for our customers.

We are your partner for commercial diving services on all floating structures.

We have a specialism in underwater ship maintenance, cleaning, and inspection, and our global fleet maintenance agreements are supported by all Wӓrtsilӓ Underwater Services locations and our approved vendors worldwide.

Work methods and procedures are shared globally with our partners to meet or exceed our client's expectations.

We’ve been delivering underwater wet/dry and hyperbaric welding solutions as a part of our portfolio since start-up in 1993.

Wet welding procedures were developed/approved for class A fillet welds. In combination with strategic alliance partners in 2014, an underwater wet welding V-Groove procedure was successfully implemented and accepted by DNV-GL. The diving training facility in the head office in Terneuzen, The Netherlands is constantly in use, training new staff on underwater welding applications.

Wet welding is a standard technology used on most of our projects on a daily basis. Permanent shell-plate repairs are executed using cofferdams designed/engineered in-house.

In 2005, we received the EMERGO Maritime Innovation Award in recognition of our OEM-approved underwater service for installing and servicing lip-type shaft seals. Since then, we’ve performed hundreds of seal repairs and overhauls on shafts with a diameter of up to 1100mm.

Its success is largely owing to our technical training, our experience in product design, and the emphasis we place on product testing, all of which have enabled us to deliver an exemplary service to the maritime industry, one which uses a widely recognized and accepted shaft seal overhaul method aligned with classification and manufacturer warranty standards.

In order to carry out the service safely and efficiently, we set up a lightweight, flexible, open habitat (FLEX-DAM) around the stern configuration, away from the natural elements and the dust generated in drydock. Its compact design is also more conducive to commercial air freight, allowing for swift mobilization in emergency situations.

We’re getting more involved in projects on offshore floating structures as a result of our technical capability to support our oil and gas customers with the best cost-effective, time-saving solutions in all circumstances.

Over time, we’ve developed a strong reputation for being a globally present, reliable, fast-response partner when it comes to (emergency) underwater repairs.
