    Working in harsh environments and extreme temperatures, long operational hours, and constantly running the equipment at maximum power until the job gets done.

    We know very well what it takes to develop a dredger for these conditions, which is why our systems are a perfect fit for the dredger market.

    Maximum efficiency and minimum labour costs are essential for the successful operation of dredgers. Wärtsilä’s products and solutions are designed to match this requirement, and are based on industrial state-of-the-art hardware components. Wärtsilä’s dredger control technology allows control of the entire dredging process from one central station. All relevant data for the production process and cost optimized control of the dredging operations are displayed to the operator.

    From the earliest times of diesel engines, Wärtsilä equipment and later on systems have been installed in complex vessels such as dredgers. Today, Wärtsilä power solutions continue to be the choice for dredgers built by the world’s leading yards. Our technical expertise is complemented by our open-minded approach to what dredging companies need and want.

    Fishing Vessels 

    With close to 50 years of experience in the fishing industry, a substantial reference list of equipment deliveries and in excess of 250 fishing vessels built to its designs, Wärtsilä has a unique know-how and expertise, backed by a truly global footprint. Our extensive offering for fishing vessels allow us to enhance the business of our customers by providing solutions that are environmentally sustainable, efficient, flexible, and economically sound.

    Research Vessels 

    Wärtsilä provides integrated solutions that are environmentally and economically sound for Research Vessels worldwide.

    Wärtsilä has supplied various equipment and solutions to many of the world’s best known research vessels, including the CEFAS Endeavour, the IFREMER Pourquoi Pas, the IMR G.O. SARS., the MARINE INSTITUTE’s Celtic Explorer, the NERC James Cook, and the CHILEAN NAVY’s Cabo de Hornos.

    Tugs and Workboats 

    The marine industry is increasingly turning to more advanced solutions as the cost of available technology decreases, and its reliability is substantiated. The environmental and economic viability of these complex solutions typically results from an integrated approach, encompassing vessel design, equipment selection, and on-site support for the shipyard and owner.

    At Wärtsilä, we believe that upcoming emissions regulations require the re-design of many existing vessel types. This is especially true of vessels operating in the proximity of large population centres, as is the case with tugs in ports.

    An integrated approach means a single contact point for project management and installation, a one-stop shop for all aspects of lifecycle support, and optimized overall performance that incorporates substantial energy savings. As all the systems are engineered to work together, their compatibility and functionality is guaranteed.

    • DEME Group
      Dredging International, part of the DEME Group, had been contracted in 2014 to undertake a major dredging project relating to the building of a new LNG terminal in Sabetta, northern Russia. In order to ensure efficient business communications between its own 8 vessels and other chartered vessels, and to retrieve almost instant dredging and survey data, DEME required stable, unlimited, and assured connectivity. Furthermore, this was needed within a time frame of 2 months, and was for a 3 month period only. Wärtsilä met this challenge with a single source solution, successfully deploying a VSAT installation including back-up communications with Iridium as well as VoiP, network management and airtime. The work was completed within just 4 weeks. So successful was Wärtsilä’s solution and fast-track capability that DEME decided to migrate the majority of its entire fleet to the same platform. This work was completed in 2016.

    • Port of Luleå, hybrid escort tug
      The Swedish Port of Luleå located on the environmentally sensitive Gulf of Bothnia, needed an escort tug operating during the summer and an icebreaker operating in harsh conditions duing the winter. This operational flexibility combined with notable environmental benefits, will be brought to the Port of Luleå by the Wärtsilä HY solution. The two Wärtsilä HY hybrid power modules ordered for the tug will be capable of operating on electrical battery power when in transit, and the “hybrid diesel-electric” mode will allow the number of prime movers utilised to be reduced to just one for various operational tasks, resulting in considerable economic gains.
