Harlingen, Netherlands, headquartered ferryboat driver Rederij Doeksen this month formally appointed the Willem Barentz, the initial of 2 brand-new 70-meter ferryboats created for eco pleasant procedure in the Waddenzee UNESCO heritage location (see earlier tale).
The event additionally noted the best of the initial 16-cylinder MTU gas-only engines.
Rolls-Royce initially introduced its brand-new MTU gas engines for aquatic propulsion in September 2016, and also delivered pre-series engines for Doeksen’s 2 brand-new catamarans to the Strategic Marine shipyard in Vietnam in late 2017.
The primary propulsion systems in each of both brand-new Doeksen catamarans contains twin MTU high-speed 16-cylinder Series 4000 gas systems, each supplying 1,492 kW and also operating on LNG provided under a long-term agreement with Titan LNG.
Directly driving the azimuth repaired pitch props, the engines make it possible for the vessels to get to travelling rates of 14 knots. Emissions from the MTU gas engines drop significantly listed below the existing IMO III restrictions without the demand for exhaust aftertreatment– with fragment mass, for instance, existing under the limit of deection. The engines releases no sulfur oxides and also just really little amounts of nitrogen oxide.
“I’m really impressed with the MTU gas engines. So far, they’ve met all our expectations in terms of performance, transient response behavior, smooth travel and low noise,” stated Doeksen taking care of supervisor Paul Melles.“Rolls-Royce has developed the very first single-fuel gas engine that can drive a fixed pitch propeller directly and is therefore capable of dynamic acceleration. That was the advantage that really made the difference for us.”
“We’re very proud that the Doeksen shipping company has chosen our new gas engines for eco-friendly operation of their ferries on the Wadden Sea, which is recognized as worthy of special environmental protection,” stated Knut Müller, head of aquatic and also governmental company at Rolls-Royce Power Systems “Joining forces with them as our partner, we will be focusing our efforts on driving the energy turnaround.”
A set of 746-kW, 8-cylinder variations of the gas engine were provided to the City of Constance, Switzerland, utility at the end of 2019 for the brand-new Lake Constance ferryboat, which is intended to be appointed throughout the upcoming winter season.
Rolls-Royce states the brand-new gas engine is especially appropriate for tugboats, ferryboats, freight vessels and also unique vessels such as research study ships. From the very start of its growth, the emphasis got on gas intake, discharges, safety and security and also velocity. The gas systems are outfitted with multipoint gas shot, vibrant engine control and also boosted turbo-charging. Multipoint gas shot makes it possible for vibrant velocity capacities, high power outcome and also lowered discharges. By managing the burning procedure, it additionally offers greater gas performance.
