and self-protect to changing conditions, and would thereby warrant and justify the designation 'Intelligent
For its part, MAN B&W believes that the IE concept offers the potential for reduced overall fuel consump- tion, because of the possibility to optimize fuel injection characteristics at many different load conditions, whereas a conventional engine is optimized for the guarantee load, typically at 90- 100 percent maximum continuous rating (mcr).
The designer and licensor also anticipates advan- tages in operational safety and flexibility, not least for slow running, while the ability to set up the engine to meet varying exhaust gas emission limits arising from local controls is likely to become an increasingly important factor in favor of the IE system and ME engine versions.
Bow Cecil is a modern tanker, having been completed in 1998 by west Norwegian builder
Kvaerner Floro, now Kleven Floro. The vessel's 14,200-bhp (11,520-kW) 6L60MC engine had been delivered with an ordinary camshaft system, but also prepared for fitting with the necessary IE elements. The electronic fuel injection and exhaust valve control systems are fitted on the engine's upper gallery, in parallel with the con- ventional camshaft.
Since the initial conversion to electronic format in the course of the vessel's trading operations in
South-East Asia in November 2000, the installa- tion has been switched several times back and forth between electronic and camshaft operation.
Crew familiarity is now such that changeover can be accomplished in about one hour 40 minutes, possibly taking around 30 minutes longer when personnel less conversant with the system are involved. Since March this year, the vessel has been run continuously with her engine under electronic control, representing an unbroken ser- vice period accounting for 3,180 of the 3,960 hours clocked up at the time of MR/EN's visit.
High-Speed Debut on the Lakes
MTU Friedrichshafen has broken new ground for the latest high-speed diesel technology, land- ing a deal where- by its potent 8 0 0 0 - s e r i e s engines will be used to power a large catamaran ferry intended for Lake Ontario operation. A 32,800-kW plant based on four examples of the 20-cylinder engine has been nominated for an
Austal 282-ft. (86-m), RoRo equipped catama- ran, designed to transport 774 passengers and 227 cars, or 10 trucks plus 70 cars, at a cruising speed of 42-knots. The vessel is intended to forge a new fast ferry link between Rochester and
Toronto next summer, offering a 2.5-hour water- borne route alternative to a typically five-hour road journey.
The installation signals the incursion of high- speed diesel machinery into a market segment hitherto regarded as the province of powerful, medium-speed engines and gas turbines. It also highlights MTU's early commercial success with
November, 2001 11 the 20V8000, which had attracted 32 engine sales in a period of little more than 12 months since its September 2000 unveiling at the SMM Exhibition in Hamburg.
The 8000-series ranks among the world's first four- stroke engines in the 8,000-10,000 kW segment to

Join and seal pipes in less than 15 minutes
With a NORMACONNECT® coupling and a torque wrench, anyone can connect high- pressure pipes in minutes — and they'll stay sealed.
Rugged NORMACONNECT® couplings are 70% lighter than welded flange joints and take up 40% less space.
They also: reduce noise and dampen vibration • save time previously spent on welding and x-rays • compensate for misalignment, angular deflection and variances in pipe O.D. • eliminate the pipe grooving and end treatment necessary with other couplings • feature a patented double-lip seal • are available in all IPS nominal O.D.'s, from 3/4" to 48" (26.9mm to 1220mm) • are rated at 16 bar to IPS 8.0" (219.1mm) by all major marine approval bodies.
For metal-to-metal, metal-to-plastic and plastic-to- plastic joints, you'll save time and money with
NORMACONNECT® Pipe Couplings. They're used on everything from ocean-going passenger ships (e.g., the first ones built in the U.S. in 40 years) to semi-submersible oil rigs.
