MAN's Part-Load Optimization a Fuel Saver
MAN Diesel & Turbo’s Part-Load Optimization is a tuning method designed to optimize fuel-oil consumption during the part-load operation of four-stroke, small-bore MAN auxiliary engines. “Part-Load Optimization works on the principle that fuel consumption is reduced at low and part load at the expense of a higher fuel consumption in the high-load range, without exceeding the IMO NOx limit,” explained Finn Fjeldhøj – Head of Small-Bore, Four-Stroke Engineering – MAN Diesel & Turbo. “We can deliver new engines pre-optimized or retrofit as necessary.
IMO Secretary-General Speaks Out Against Regional Emission Trading System
International Maritime Organization (IMO) Secretary-General Kitack Lim has written to senior European officials expressing his concern that including shipping in the European Union’s Emission Trading System (EU-ETS) could undermine efforts to reduce greenhouse gas (GHG) emissions from shipping on a global basis. In a letter to Martin Schulz (President of the European Parliament), Jean-Claude Juncker (President of the European Commission) and Donald Tusk (President of the European Council)…
Slide Fuel-Valves Pass Noteworthy Milestone
First introduced at the turn of the millennium, MAN PrimeServ – MAN Diesel & Turbo’s service division – recently retrofitted its 20,000th slide fuel-valve. Slide fuel-valves come as standard on all new MAN B&W engines but can also be retrofitted on MC engines. The slide fuel-valve eliminates the so-called "sac volume," which reduces fuel-oil consumption and, furthermore, eliminates dripping from the fuel-valve nozzle. Compared to conventional valves, the slide fuel-valve has NOx-reduction potential. According to MAN, the reduced sac volume leads to an improved combustion process, resulting in fewer deposits throughout the gas ways and a reduction in overall emissions, such as HC, NOx and particulate matter.
Slide Fuel-Valve a MAN Success Story
First introduced at the turn of the millennium, MAN PrimeServ – MAN Diesel & Turbo’s service division – recently retrofitted its 20,000th slide fuel-valve. Christian Ludwig – Head of Retrofit & Upgrade – MAN Diesel & Turbo, said: “Slide fuel-valves have proved to be very popular within the marine, two-stroke market. Really, it’s a case of having introduced the right technology at the right time and the slide fuel-valve’s strong market performance is testimony to the fuel savings and increased environmental profile it brings to working vessels.
New Small-bore Two-stroke Diesel Introduced by MAN
MAN Diesel & Turbo introduces new small-bore two-stroke, updates designs of ME-B & G series engines. MAN Diesel & Turbo’s updated engine programme features several, positive changes to its two-stroke marine segment. The most significant of these is to the ME-B and G portfolios that are increasingly finding favour in the coastal & river segment in major markets such as China, Japan and Russia, and in container traffic, respectively. The programme introduces an entirely new engine – the S30ME-B9 type, which joins the existing 35, 40-, 46-, 50- and 60-cm models in the small-bore ME-B family. The economical ME-B design utilises a camshaft-operated exhaust valve and an electronically controlled fuel-injection system designed to meet Tier-II emission requirements.
MAN Wins Power Contract for Spanish Ships
Spains's Empresa Naviera Elcano, S.A., aninternational shipping group, placed an order for two medium-speed MAN L27/38 engines as part of a propulsion package for a new vessel. The units will be constructed at the MAN Diesel & Turbo facility in Frederikshavn, Denmark, and will power a 7,000-dwt asphalt and oil-products tanker to be built at Sedef Shipyard in Turkey. The 6-cylinder main engines each deliver 2,040 kW at 800 rpm. Elcano has chosen the engines as part of a MAN Diesel & Turbo propulsion package that also comprises an Alphatronic 2000 propulsion control system…
MAN B&W S80ME-C9 Engine Passes Type Approval Test
MAN Diesel & Turbo has announced that its latest, mark-9, 80-cm-bore engine recently passed its Type Approval Test (TAT). The super-long-stroke S80ME-C9 engine now powers a Maersk Line container vessel and successfully completed its TAT at HHI-EMD, the Engine & Machinery Division of Hyundai Heavy Industries Co., Ltd., in Korea. The TAT programme ran over three days and was completed in January after a comprehensive series of test runs. All international classification societies were represented during the presentation of the engine…
MAN B&W Engine Retrofits Meet IMO Legislation
While IMO guidelines are observed on a voluntary basis by the international shipping community, their adoption becomes mandatory for certain vessels when an Approved Method for complying with the regulations is available. MAN Diesel & Turbo has developed Approved Methods for a number of its engines, requiring some shipowners to retrofit engines to follow IMO emission limits. The International Maritime Organisation (IMO) develops regulations and guidelines for international shipping. Its latest revision of emission regulations addresses NOx emissions on engines installed aboard ships built between 1990 – 1999 that are expected to be active in the global fleet for another 10 or 20 years, but that were not previously covered by any guidelines.
MAN Diesel Expands CP Propeller Portfolio
In response to the market demand for very large CP propellers up to and beyond 30,000 kW and with diameters over eight meters, MAN Diesel is expanding its propeller portfolio to add two new, propeller hub-sizes – VBS2080 and VBS2240 (2080 mm and 2240 mm hub diameters respectively). These propeller sizes are typically destined for ConRo vessels, shuttle tankers and special vessels with high ice classes, and powered by MAN B&W two-stroke MC-C or ME-C main engines that directly drive a CP propeller.
New MAN Engine with High Power Density
MAN Diesel has broadened its product portfolio with the development of its new, Type K80ME-C9 two-stroke, low-speed engine. The ME-C9 engine recently passed the final milestone on its way to commercial applications in the marine sector with a successful Type Approval Test (TAT). The first production version of the MAN B&W-branded engine successfully completed its TAT programme at Hyundai’s (HHI-EMD) works in Ulsan, Korea. HHI-EMD’s two-stroke engine assembly and test shop #2 was the venue for the test and hosted representatives from the shipyard…
