The technology group Wrtsil has been contracted to supply a comprehensive package of engines and propulsion machinery for a new Cutter Suction Dredger (CSD) vessel. When delivered, the Spartacus, which is being built on behalf of Belgium based Dredging International (DEME), will be the worlds most powerful CSD and the first ever to be fuelled by liquefied natural gas (LNG). It is being built at the Royal IHC yard in the Netherlands. The order with Wrtsil, worth around 20 MEUR, was booked in the fourth quarter of 2016. The 164 metre long vessel will have a total installed power of 44, 180 kW. It will feature four 9-cylinder Wrtsil 46DF dual-fuel engines, two 8-cylinder Wrtsil 20DF dual-fuel engines, and a Wrtsil LNGPac fuel gas storage and supply system with a newly designed bilobe tank arrangement. Wrtsil will also supply two fixed pitch propellers with shaft assemblies and HP nozzles, and two tunnel thrusters, as well as commissioning, site supervision, and extended project management services. The Wrtsil equipment is scheduled for delivery to the yard during the fourth quarter of 2017. Wrtsil has worked in close cooperation with the owners starting from the early stages of this large project. This has enabled a well engineered and fully integrated propulsion arrangement, and an LNG fuel system that is optimised for the needs of the vessel, says Arthur Boogaard, General Manager, Business Development Special Vessels at Wrtsil.
