ExxonMobil Helps Danaos Extends Piston Overhaul

MV CSCL Europe’s 12-cylinder DOOSAN-MAN B&W K98MC-C engine is lubricated with Mobilgard 570, a cylinder oil formulated by ExxonMobil to reduce piston wear and deposits, and extend piston overhaul intervals in two-stroke marine diesel engines.

Engineers from Athens-based Danaos Shipping together with ExxonMobil, reportedly extended the overhaul interval required for a piston in a DOOSAN-MAN B&W 12-cylinder K98MC-C engine from 16,000 hours to 42,575 hours. A recent overhaul revealed that cylinder number 11 was in remarkably good condition, with a negligible liner wear rate. The achievement took place aboard the containership MV CSCL Europe, which is chartered to China Shipping Container Lines. Representatives from Danaos Shipping and ExxonMobil systematically monitored the condition of the engine throughout the overhauling process.

MES Completes the World’s Largest Diesel Engine

Mitsui Engineering & Shipbuilding Co., Ltd. (MES) has completed the world’s largest class diesel engine (MITSUI-MAN B&W 1198MC type: 69,920kW) at its Tamano Works and delivered the engine to Imabari Shipbuilding co., Ltd. in October 2001. The engine has been installed on a 6,000 TEU container carrier. The second 11K98MC type was also completed for the same shipbuilder in December 2001. MAN B&W Diesel A/S developed the K98MC type diesel engine series as a highly efficient main engine for large container carriers in 1999. The cylinder bore is 980mm and can develop 7,780ps (per cylinder). In April last year, MES completed the MITSUI-MAN B&W 10K98MC (57,200,W) in the same series for 5,500 TEU container carrier built by Imabari Shipbuilding Co.

MAN B&W to Present New Engine Developments at SMM

The MAN B&W Diesel Group presents two new engine developments as well as the next turbocharger generation at the SMM trade fair (Vessel Marine Ocean Engineering) held in Hamburg, Hall 6, Stand 6001, from September 24 to 28. On an exhibition space of 350 square metres, the international business group proves its right to technology leadership with the title “Prime Movers“. The central exhibits at the stand are a huge piston of the K98MC two-stroke engine – the largest engine worldwide, and a product of the completely new developed TCA exhaust gas turbocharger series. - V 48/60B: The further development of the successful 48/60 engine is, in particular, suited for application in cruise vessels, ferries and large multi-purpose freighters.

New Dimension for Hapag-Lloyd

Although long in the vanguard of containership technology, Germany's Hapag-Lloyd did not feel compelled to join the early rush towards vessels of wider-than-Panamax gauge. Once the prudent Hamburg company decided to embrace the concept, however, it opted for one of the largest and most powerful embodiments of the post-Panamax genre to date. Its planned commissioning this fall of the first of a new breed of 7,500-TEU linehaul carrier follows recent years' heavy investments in Panamax-optimized tonnage up to 4,890-TEU capacity, and signals a step change in unit scale economics applied to its Europe/Far East express service. The new behemoths will be of around 100,000-dwt and 80,000-gt, stowing 17 boxes abreast on the weatherdeck, within main dimensions of about 1,049 ft.

First K98MC Engine Is Successfully Tested

Earlier this year, MAN B&W's Korean licensee, Hyundai Heavy Industries began production of the first MAN B&W 7K98MC type engine. The structure was completed in August, precedent to an extensive prototype measurements that were taken to verify and record the calculations that formed the basis for the engine. Following successful completion of the prototype tests, results fulfilled all design targets for performance, heat load and stresses, as well as exhaust gas emissions. Measuring 98-cm bore, the engine holds a catalog output of 7,780-bhp/cyl. With the first of its class powering a 4,800-teu container vessel for German owner Hapag-Lloyd, this 10-engine series, which will be followed by five 10-K98MC-C models, is scheduled for delivery in 1999-2000.

Hyundai, MAN B&W Are At Top of Engine Power

Rising Korean aspirations as to market influence and technological standing could alter the established order in an important segment of the engine business. While MAN B&W announced opening contracts for its new L21/31 design as a marine auxiliary, Hyundai Heavy Industries was preparing to roll-out its first-ever, self-originated engine type targeted at a similar power range. The H21/32 signals the emergence of Hyundai, the world's largest producer of marine diesels, as a designer in its own right. The company's development of the in-house Himsen brand denotes a move towards increased technological self-reliance, given the wholesale dependence up until now on manufacturing licenses from foreign engine firms.
