IMO issues new circulars The IMO has issued new Circulars and MEPC.1/Circ. 765 gives information on new retrofitting kits for MAN B&W S70MC and S50MC type engines.In accordance with the provisions of regulation 13 of MARPOL Annex VI, engines of more than 5 MW and a displacement per cylinder of 90 litres or above, installed onboard ships built between 1 January 1990 and 31 December 1999, should be fitted with methods for NOx emissions reduction (kits) when such kits are available and approved by an Administration.Ships with engines for which the kits are approved are required to be fitted with them at the first renewal survey of the IAPP Certificate which is scheduled 12 months from the date on which the Administration gives notice of the certification of the approved kit.According to MEPC.1/Circ. 764 and 765, the Danish Administration reported on the certification of the approved method for MAN B&W S70MC and SM50MC type engines on 11 August 2011. Therefore, installation of the kits for such engines will be mandatory no later than the first renewal survey for the IAPP Certificate which occurs on or after 12 August 2012, subject to commercial availability.IACS has informed the IMO that data provided ...

New G80ME-C9.2 main engine Leading engine manufacturer MAN Diesel & Turbo is currently involved in several VLCC projects, which involve its new G80ME-C9.2 main engine.VLCCs were originally the primary target behind the introduction of the new prime mover, MAN said.The shipping industry is currently debating whether or not VLCC service speed should be reduced to 13 knots from the existing 15 to 15.5 knots, a scenario which the G80 is tailor-made to meet, the company claimed.Ole Grøne, MAN's senior vice president low-speed promotion & sales said: "We are delighted with the market response to the G-type. We viewed its introduction as both viable and timely and are pleased that the market has seen fit to back this up."The G-type programme was introduced to the market in October 2010 with the G80ME-C9 model. MAN subsequently expanded the ultra-long-stroke programme in May 2011 with the addition of G70ME-C9, G60ME-C9 and G50ME-B9 models.The G-types have designs that follow the principles of the large-bore Mk-9 engine series that the company introduced in 2006. Their longer stroke reduces engine speed, thereby paving the way for ship designs with unprecedented high-efficiency, MAN said.Tankers have traditionally used MAN B&W S-type engines with their long stroke and low ...
