First Class Approved 3D Printed Ship’s Propeller Unveiled

The world’s first Class approved 3D printed ship’s propeller, the WAAMpeller, has been unveiled following rigorous testing verified by Bureau Veritas at Damen Shipyard Group’s headquarters in the Netherlands. The groundbreaking propeller is the result of collaboration between RAMLAB, Promarin, Autodesk, Bureau Veritas and Damen, who started pooling collective resources and knowledge to develop the world’s first 3D printed ship’s propeller seven months ago. Promarin provided the design of the triple-blade propeller.

Wartsila Propulsion System for New NMDC's Dredger

Wärtsilä supplied the full propulsion package for National Marine Dredging Company's (NMDC) new, state-of-the-art Trailing Suction Hopper Dredger (TSHD) launched in September. The 6,000 m3 capacity TSHD was designed by the IHC shipyard in the Netherlands in close cooperation with NMDC. The customized solution combines a shallow draft and a deep dredging depth with high manoeuvrability. The vessel has been specially designed to operate in high ambient temperatures, and the Wärtsilä machinery is capable of operating efficiently in such conditions.

Wärtsilä to Power Viking Line Ferry

Wärtsilä will supply the engines, the navigation system and a broad scope of other products and systems for a new luxury and environmentally friendly ferry being built for the Finland based operator, Viking Line. The ship is being built at the Xiamen Shipbuilding Industry yard in China and there is an option for a second vessel. The order with Wärtsilä was booked in October 2017. Six Wärtsilä 31DF dual-fuel engines running primarily on liquefied natural gas (LNG) will provide the propulsion and power for the vessel.

Wärtsilä Supplies Propulsion for Fishing Vessel

Lunar Fishing Company Ltd, based in Scotland, is replacing its existing Lunar Bow purse seiner trawler with a new ship having the same name. The primary considerations were to achieve both economic and environmental benefits through selecting the market’s most efficient propulsion machinery. The vessel is being built at the Karstensens Skibsvaerft shipyard in Denmark and will feature a fully integrated propulsion solution from Wärtsilä. The main engine chosen is the Wärtsilä 31, listed by Guinness World Records as being the world’s most efficient four-stroke diesel engine.

Wärtsilä Launches Fuel-Saving Pre-Swirl Stator

EnergoFlow is a new energy saving solution that will return ship operators’ investment in less than two years, according to its developer Wärtsilä. By reducing the power losses which occur in the propeller’s slipstream with an optimised inflow, Wärtsilä’s solution improves fuel efficiency by up to 10 percent. The technology group Wärtsilä launches the newest solution in its propulsion efficiency portfolio during November. The product will be introduced at the Europort event in Rotterdam, the Netherlands, on Tuesday, November 7.

SCHOTTEL's New ProAnode Goes to Market

The first SCHOTTEL Rudderpropeller with the newly developed and patented ProAnode has left the German factory in Doerth. According to the manufacturer, ProAnode’s new form and position sets higher standards in corrosion protection, thereby extending the lifecycle of the thruster. Furthermore, moving the position of the anode from the outside surface into the cross-section of the nozzle tail leads to subsequent operational benefits, such as reduced flow interference, resulting in fuel savings.
