Investment in Design conventional camshaft drive in favor of electronically-controlled fuel injection and exhaust valve actuation. The arrangements will enable engine settings to be exactly matched to changing oper- ating requirements throughout the voy- age profile, offering the prospect of reduced overall fuel consumption, greater operational flexibility and less- ened environmental impact.

One benefit will be the lower sailing speeds obtainable for restricted water transits as a consequence of the possibil- ity to safely run the engine at extremely

Circle 319 on Reader Service Card low crankshaft speeds. "As little as four knots are possible, and precisely this will mean greater maneuverability in the

Sue/ Canal," pointed out Klaus Marek, head of Hapag-Lloyd's ship technology and inspection department. By compari- son. the company's four 7,500-TEU

Hamburg Express-class vessels, fitted with conventional camshaft 12K98MC engines, have a minimum speed of six knots. "The special plus of the electronically regulated main engine is that it uses two-percent less fuel," observed Marek.

The report in Hapag-Lloyd News indi- cated a potential annual saving for the nascent trio of 8.145-TEU container- ships as around 3,000-tons, or $360,000.

More conservant use of heavy fuel oil, both in absolute terms and per unit of cargo volume, obviously has environ- mental as well as economic benefits, and

Nox (oxides of nitrogen) engine exhaust emissions are expected to come down to 12.3 grams per kW-h (kilowatt-hour) as a result of the nomination of I2K98ME plant. "We have opted for diesel engines with electronic control systems because, in the future, we want to be able to react more flexibly to environmental require- ments," Marek added.

MAN B&W's recent inclusion of a still wider-bore, new engine design in its

ME program, in the shape of the mighty

K108ME-C type, provides liner opera- tors with an electronic, single-engine option for unit power requirements up to an astonishing 132,300-bhp.

Research as the

Building Block

An absence of complacency over its position as the global market leader in newbuild construction is demonstrated by Hyundai Heavy Industries' increasing plough-back of earnings into research and technological development. The raised level of annual expenditure on

R&D, coupled with the group's strength- ening of its network of research insti- tutes, express a belief in the fundamen- tal link between applied research, inno- vation. competitive position and market
