  A major cross-industry initiative led by Wärtsilä, MAN Diesel & Turbo and Winterthur Gas & Diesel to develop basic technologies for use in 2- and 4-stroke marine engines has been officially launched. The Hercules-2 project is aimed at fostering environmentally sustainable and more efficient shipping. It is in line with general European Union policy and is partly funded by the EU.  Altogether, 32 marine industry partners from 11 different companies, 16 universities, and five research organisations are cooperating in this project, with NTU Athens as coordinator. The R&D efforts focus on four main areas. These are: the application of alternative fuels and the optimisation of fuel flexibility to facilitate seamless switching between different fuels; the development of new materials to support high-temperature component applications; the development of adaptive control methodologies to significantly improve an engine’s performance throughout its life span; and to achieve near-zero emissions via combined, integrated, after-treatment of exhaust gases. “The greatest of the many benefits stemming from Hercules-2 will be the development of new technologies that have a positive impact on our customers’ profitability. Another is the significant contribution this project will make to more environmentally sustainable shipping,” says Ilari Kallio, Vice President, R&D, Engines, speaking ...

  Mitsui Engineering & Shipbuilding (MES) – the MAN Diesel & Turbo licensee – recently demonstrated the liquid-gas-injection concept successfully in Japan. The successful demonstration took place on 17 June, 2015 using the very first ME-LGI engine to ever be commercially produced. The engine, with the type designation 7S50ME-B9.3-LGI, is bound for a vessel currently under construction by Minaminippon Shipbuilding Co., Ltd. for Mitsui O.S.K. Lines, Ltd. Ole Grøne, Senior Vice President – Low Speed Promotion & Sales – MAN Diesel & Turbo described the event as a significant milestone in the development of Diesel technology and said: “The immediate market acceptance of our ME-GI (Gas Injection) engine confirmed the growing demand for low-sulphur, non-HFO options in the face of increasingly stricter sulphur limits in fuel. In turn, extending our dual-fuel engine programme with an ME-LGI unit that can run on liquid fuels was therefore a natural step.” He continued: “The interest in our ME-LGI engine confirms this dual-fuel, lowspeed trend and will offer even more alternatives to HFO, which – apart from methanol – will include LPG, dimethyl ether (DME), and (bio-) ethanol, as well as several other, low-sulphur, low-flashpoint fuels.” Grøne concluded: “We welcome our partners’ interest in ...

  MAN Diesel & Turbo’s two-stage turbocharging development project, ECOCHARGE, recently passed a significant milestone on its way to a successful market introduction. The company reports that individual MAN TCR20 and MAN TCX17 units – combined as a single, two-stage turbocharging system – has had a first run on an MAN 12V35/44 gas engine on a test bed at its Augsburg, Germany works. The company reports that the ECOCHARGE system has been developed for both gas- and HFO-burning engines. Now that the TCX series has proven its strengths and functionality on the burner rig, the new ECOCHARGE system will run over the coming months on the engine to prove its strengths and functionality. The test is the first real opportunity to prove the thermodynamic calculations on an engine, which is key to a successful field test. MAN Diesel & Turbo sees great potential in two-stage turbocharged engines, which can be seen in the spate of recent orders for such solutions. Two-stage turbocharging differs significantly from single-stage turbocharging in that it also copes with the demands of a high-pressure stage. The MAN TCX turbocharger has been especially developed for two-stage turbocharger applications. The combination of a MAN TCR20 – for the ...

 MAN has issued a Market Update Note providing information on the Light Running Margin (LRM) which is an important design parameter for the safe and efficient operation of a ship. The changed circumstances in the shipping industry  have led MAN Diesel & Turbo to change the recommendation for LRM.In brief, a ship should have a sufficient LRM such that:a safe and satisfactory ship speed can be maintained in heavy weather and/or with a fouled hullship accelerations needed for safe and efficient manoeuvring operations can be achieveda barred speed range can be passed quickly (which is often required also at zero ship speed, i.e. at bollard pull).  http://www.youtube.com/watch?v=C7e6RLMk5e8 Light Running Margin (LRM)To align with the rest of world’s ambitions to reduce greenhouse gas emissions, the shipping industry has developed the energy efficiency design index (EEDI) in cooperation with IMO. Combined with the steady increase in oil prices seen in the period from 2006 to 2014, the result has been improved ship designs with lower CO2 emissions relative to their transportation capacity.Lowering of the SMCR propulsion power installed is a key parameter for achieving a more fuel and CO2-efficient ship, evaluated according to the EEDI. Other parameters include lowering of the hull resistance, ...

  MAN Diesel & Turbo’s Propeller & Aft Ship organisation has won an order to retrofit and upgrade a series of 11 × 37,500 dwt vessels from the Odfjell chemical tanker fleet. The vessels are of the Kværner Class and are due to dock during 2015-17, at which time the upgrades will be implemented. The first vessel, ‘M/T Bow Clipper’, will dock and be upgraded in August 2015. Each vessel has an MAN B&W two-stroke engine powering a four-bladed, controllable-pitch propeller and a PTO-driven shaft alternator. The vessels’ new service speed at reduced main-engine output – combined with the implementation of MAN’s highly-efficient Kappel propeller blades, a fairing cone and a pre-fabricated rudder bulb kit – will all contribute to power savings and reduced exhaust-gas emissions. The Kappel blades, fairing cone and rudder bulb are designed and customised for the tanker’s hull and rudder designs. The calculated power saving has been verified by tank-test analyses at MARINTEK (Norwegian Marine Technology Research Institute) as reported in preliminary results. “It’s a very exciting project and we are proud to be part of it. With our new design possibilities, we are furthermore looking forward to offering this fuel-saving concept to other fleets with ...
