Quantum leap claimed in ship propulsion

Reducing emissions by at least 75% Claims have been appearing in the media that a company has redefined marine propulsion, saying that its system increases propulsion efficiency and reduces emissions by at least 75% for various sizes of ships.Gamma Light and Heavy Industries seems somewhat reticentabout revealing details about its system or even about its own location. But 'The Gamma Propulsion System' (TGPS) seems to be based on electrically-driven pump-jet type thrusters distributed around the ship. The company says that its system is a far more efficient way of converting horsepower into thrust - a ship originally propelled by a 3,000bhp main engine could achieve equivalent performance with TGPS from a total installed power of 600bhp to 750bhp.Tank tests of the pump jet have been witnessed by a surveyor from Lloyd's Register Asia; results recorded on the certificate suggested that at different motor frequencies, thrust measurements of between 5.24 times and 6.17 times "better than an average ship's propeller" were recorded. The tests were carried out in Queensland, Australia, on behalf of Douglas Bruce/Pacific Paramount Ltd of Brisbane; apparently to verify the performance of the electrically-driven pump units for both ship propulsion and use in a water theme park.The company ...

Algoma Central Corporation has chosen Wärtsilä to supply complete propulsion systems

With integrated scrubbers for six Great Lakes vessels The full propulsion system with integrated fresh water scrubber lowers operating costs while reducing the vessel's environmental footprint by allowing owners to use high sulphur fuels in Emission Control Area (ECA) Zones and meet sulphur emissions restrictions. This represents the first order for the new integrated Wärtsilä scrubber concept. Once in operation, the vessels will set new standards for environmentally sustainable shipping on the Great Lakes and for cargo vessels in general.Wärtsilä has been awarded the contract to supply fresh water integrated scrubbers for a series of six vessels with an option for a further two, being built to transport bulk commodities on North America's Great Lakes and St. Lawrence Seaway, for the Canadian owner, Algoma Central Corporation.The integrated scrubber order is the last one of a series of Wärtsilä supply contracts awarded for these vessels. In addition to the unique integrated scrubber system, the complete solution provided by Wärtsilä includes engineering support, highly fuel efficient engines, propulsion machinery and a bilge water system. The orders for these various systems were booked on an incremental basis in 2011. All equipment included in the Wärtsilä solution will be supplied in co-operation with the ...

Rolls-Royce to deliver world’s first gas power system for tugs

High efficient engines and propulsion systems Rolls-Royce, the global power systems company, has signed a contract to deliver highly efficient engines and propulsion systems for the world's first Liquid Natural Gas (LNG) powered tugs.The two vessels have been ordered by Norwegian company Buksér og Berging AS and will enter service in late 2013 for Statoil, the international energy company, and Gassco, the operator of the gas transportation network off the Norwegian coast.Robert Løseth, Rolls-Royce, Senior VP - Merchant, Propulsion Systems and Engines said: "This is a breakthrough for our Bergen gas engines and cutting edge propulsion technology. The choice our customer has made highlights the industry leading engine performance, fuel consumption and low methane emissions that Rolls-Royce can offer, which is now being applied to tugs. "In addition to two gas engines and an LNG tank system, Rolls-Royce will deliver an azimuth propulsion system for each tug, which will provide the quick and responsive manoeuvring that is critically important for tug operators. These tugs will be the first vessels to use the newly designed Rolls-Royce US35 azimuth thrusters, which have improved hydrodynamic performance and hull integration.The combined power and propulsion system is estimated to give a reduction in CO2 emissions ...

Novel Container Vessel Sets New Standards

Highly fuel efficient 2000 TEU Container Feeder Vessel The Danish Naval Design and Marine Consultancy Knud E. Hansen A/S and joint venture partner ABB have developed a highly fuel efficient 2000 TEU Container Feeder Vessel. The vessel's main dimensions have been optimised for calling in Bangkok, but the design features will deliver great benefits to operators and the environment on any route.The design delivers excellent fuel economy, reduced environmental impact, reduced need for water ballast, slow-steaming potential and flexible transit speeds, loading flexibility as well as increased container capacity including higher than usual reefer capacity.Propulsion efficiency, manoeuvrability and redundancyPropulsion efficiency is significantly boosted by an electrically driven counter rotating ABB Azipod unit, which is fitted behind the directly driven main propeller. The power balance between the main propeller and the Azipod is approximately 65/35 %, and as the Azipod can be turned 360 degrees, the vessel will have state of the art manoeuvrability, which reduces or eliminates the need for tug boat assistance in port.Compared to a vessel with a conventional diesel-direct propulsion system the main engine has been considerably down-sized, and with a correspondingly smaller propeller diameter in combination with a low shaft line, ballast water to submerge the ...

Hybrid propulsion for Italian Coast Guard

Marine propulsion systems are reducing CO2 emissions and enable greater fuel savings Italian shipyard Cantieri Navali Megaride has proven that diesel-electric systems are suitable not only for large merchant and naval vessels but also small ships.It recently commissioned Siemens Marine Solutions to equip a 65m RINA class offshore supply vessel (OSV) which was designed by Errenavi, Rome, for the Italian coast guard and features a Siemens Siship EcoProp hybrid propulsion system.Working in close cooperation with ZF Marine, its preferred gearbox supplier, Siemens ensured delivery of a total hybrid propulsion solution tailored to the needs of the customer. This included a ZF 9300 PTI 'hybrid-ready' transmission and two Siemens electric motors (180 kW at 3,000 rpm) matched to two CAT 3512 C diesels (1,765 kW at 1,800 rpm). The speed of the vessel using diesel mode is approximately 12 knots and 8 knots in electric mode.For this project the ZF 9300 PTI 'spur gear' version was used, which acts as a ratio multiplier, keeping the footprint of the transmission small and allowing a wide range of ratios for each transmission. The system has no boost function and no battery driven propulsion mode. Propulsion modes are diesel only, directly through the transmission, ...
