Ever since the global financial meltdown of 2008 briefly crippled the world leisure boat market, Volvo Penta adopted a strategy to increase its commercial market share with its family of innovative propulsion systems and controls. Last week off the west coast of Sweden, Maritime Reporter & Engineering News got up close and personal with the new D8 diesel and IPS15 pod, as well as the full range of command and control products courtesy of a day of test drives at Krossholmen, Volvo Penta’s Global Marine Testing Center.

Example of a bulk carrier with four Norsepower Rotor Sails on the port side   Finnish marine engineering company Norsepower Oy Ltd. announced this week that it will bring to the commercial maritime market an auxiliary wind propulsion solution aimed at maximizing cargo ship fuel efficiency, with first sea tests on a Finnish cargo ship slated to begin later this year.Norsepower’s Rotor Sail Solution is an updated version of the Flettner rotor, a concept that dates back to Finnish engineer Sigurd Savonius in the early 1900s. The Flettner rotor gets its name from German engineer Anton Flettner, who was the first to build a ship which used spinning vertical cylinder rotor sails for propulsion.Though the basis for this technology is not entirely new, Norsepower has improved upon the original concept with various improvements. Norsepower said its update uses improved technology, advanced materials and a leading-edge control system to allow the main engines to be throttled back when... [More]

Propeller Shaft Seals of Approval for Two Wärtsilä Systems

Ships with Wärtsilä’s Airguard and Oceanguard propellor shaft seals have no need to change from mineral oil to a bio-degradable lubricant (formally ‘an Environmentally Acceptable Lubricant’) when they're in U.S. waters as these seals meet Vessel General Permit (VGP) requirements. How these particular propeller shaft seals comply, and more about these newish VGP amended regulations follows:Seals,bearings and stern tube arrangement: Image courtesy of WärtsiläNo oil-to-sea interfaceWärtsilä explain that Airguard is suited for merchant ship stern tube and thrusters, and Oceanguard for cruise, ferry and offshore stern tube, thruster and electric pod face type sealing.  The Airguard and Oceanguard sealing systems have been designed with no oil-to-sea interface (the essential point): an air chamber or separation space within the seal captures any water or oil leakage, which is then transferred to inboard tanks for monitoring and further tre...

New Shipbuiling Contract for Cassens-Shipyard in Emden

German shipping company Norden-Frisia has ordered a new diesel-electric ferry which will be built at Cassens Werft in Emden. The delivery is expected in summer 2015. According to the shipping company the new build with a modified exhaust after treatment system from Kurre Abgastechnik and with a diesel particle filter. Norden-Frisia says that the power plant will reduce emissions by up to 90% and very fine particulates by up to 99%, “…with this we will have almost the same emission values like with a natural gas driven ferry”. Same like the FRISIA VIII, which was the first German island ferry awarded with the German environmentally quality certificate “Blue Angel Ship Design”, also the new build is planned to receive this award.The vessel will be of identical dimensions to Norden-Frisia’s FRISIA IV, which features 70.7 m. It is planned to have the double ender’s Voith Schneider propellers in combinatory operation, a development which the owners... [More]

MAN’s New EcoCam reduces fuel consumption

MAN EcoCam further optimises slow-steaming concept MAN Diesel & Turbo has introduced the MAN EcoCam as a retrofit solution for the low-load optimisation of its low-speed, mechanical engines with single turbochargers. The EcoCam offers significant fuel savings of 2 - 5 g/kW – with short payback times – and delivers an increased Pmax cylinder pressure through the adjustable exhaust-valve timing.Christian Ludwig – Head of Retrofit & Upgrade – MAN Diesel & Turbo, said: “Slow-steaming is now an established industry standard across all segments, including the tanker and bulker markets, and MAN continuously seeks to further refine its technology and improve efficiency. The MAN EcoCam adjusts the exhaust-valve timing between 10 and 60% load, giving a 2 - 5 g/kW fuel saving with minimal to no interruption to a vessel's schedule during installation. . For smaller engines, this can result in a payback period of as little as 1½ years as is the case,... [More]

Sister Ship of the “Norwegian Breakaway”, the “Norwegian Getaway” delivered

After transfer from Southampton service as a hotel vessel at the “Super Bowl” in New York – First cruises in the Caribbean During a ceremony at the beginning of January 2014 in Bremerhaven, Norwegian Cruise Line took delivery of the 145,655 gross ton cruise ship Norwegian Getaway from MEYER WERFT after a building period of only 15 months. The ship, the second of two Breakaway Class ships, is being delivered just nine months after the launch of sister-ship Norwegian Breakaway. Following delivery today, the ship is sailing to Rotterdam for the start of inaugural festivities which will continue in Southampton before the ship departs for her transatlantic cruise to New York. The ship will be christened in Miami on February 7.The cruise liner starts the first transfer from Southampton to New York with around 1.500 crew members from over 60 nations. In New York the vessel will act as a hotel ship for the super event “Super bowl”. After the christening ceremony i... [More]

A Real Innovation in Cruise Ferries

Again: Norwegian shipping companies taking the lead in propulsion innovationMS Stavangerfjord is worldwide the first large cruise ferry powered exclusively by natural gas (using "single fuelled gas engines"). For this reason, this ship is the most environmentally friendly in their class with significant environmental benefits compared to ships powered by traditional heavy fuel oil. Emissions of nitrogen oxides (NOx) are reduced by 92 percent. Emissions of sulfur are eliminated completely, while particulate emissions are reduced by 98 percent. Last but not least, the technology the shipping company Fjord Line uses reduces emissions of greenhouse gases (CO2) by 23 percent. Stavangerfjord has been set in service in mid of July 2013 and runs, as expected, fully satisfactory for its owner.The used “green motor technology from Rolls Royce” is well-proven on a number of ferries and ships used in the offshore industry. In addition to reducing emissions to a minimum, the ships will ... [More]
