Propulsion in the New Millennium
A record number of participants heard 24 papers covering a variety of topics from engine trends and fuels of tomorrow to emission legislation and safety improvements. In the first paper Peter Sunn Pedersen, vice president of R&D at MAN B&W looked at low-speed engine development. Daniel Paro, senior vice president of technology at Wärtsilä NSD looked at what new fuels we may see in the next millennium including hydrogen, wood based oil and orimulsion. He also examined the engine technology currently used in medium-speed engines, and that which may be employed in the future. The last paper in the session, from Roetger Driessen after sales division manager with MaK, looked at the service experience of its M32 engine.
Opening the second session, Luis Vilches, chief executive of Manises Diesel asked if European engine manufacturers could survive against the competition from the Far East.. Stefan Fankhauser from Wartsila NSD then took the podium to tell delegates about "The largest common rail system in the World" used on the Sulzer RT-flex engine design. The session ended with a paper from DNV`s Tor Erik Andersen examining machinery classification in the new millennium.
After lunch Stefan Lemieszewski of the Swedish Maritime Administration told delegates his views on current and future emission legislation. He gave the background to the introduction of Sweden`s environmentally differentiated port and fairway dues, including some statistics about how far NOx and SOx pollution travels. Germanischer Lloyd`s Hans Jakob G<#138>tjens then described the way engine builders get certificates showing compliance to the IMO`s NOx code. Continuing the theme, Bert Buchholz from Motoren-und Energietechnik explored possibilities for reducing emissions from large marine diesel engines.
Looking from the other side of the equation was Rolf Persson from TT-Line and owner/captain R<#154>rd Braren who both operate ships fitted with SCRs to meet the Swedish limits. TT-Lines Nils Dacke has an SCR fitted to one of its four main engines while Captain Braren`s Cellus has catalysts fitted to both main and auxiliary engines. Both operators described the costs and benefits as they apply to their operation.
There were then three papers on gas turbines powering cruise ships. Jari Nurmi R&D manager of Deltamarin gave details of the study it undertook for Royal Caribbean, including the propulsion options. The process of assembling and testing the gas and steam turbines and generators into a propulsion unit was described by David Whisenhunt of S&S Energy Products. Giving the opposite view was MAN B&W`s Horst Kohler who put forward the operating benefits of using diesels as prime movers in cruise ships.
Second day`s proceedings
Richard Kelly from Alfa Laval opened the second day by giving delegates an idea of how the company tests centrifuges, and highlighted the trade-off between separator efficiency and flow rate. Diesel-electric booster drives (between 2 and 15MW) was the subject of a paper from Siemens` Peter Andersen. To finish the session, Alan Lough from Lloyd`s Register looked at the how the Millennium Bug (and other date related problems) could effect marine systems.
Opening the cutting edge project section, Stena`s Stig Bystedt gave some information on the company`s new V-max VLCC design. In a joint presentation Gerassimos Strintzis, chairman of Strintzis Lines, and Wim Stout of Van der Geissen-de Noord explored the thinking behind the propulsion installation in the fast conventional ferries the yard is building for the operator. Joachim M<#159>ller of Schottel looked at the advantages of cargo vessels adopting podded drives.
Professor Constantin Gallin of Gallin Marine Consultants, and Wartsila NSD`s Frederic Porchet opened the final session with a formal safety assessment (FSA) of a two-stroke engine in a suezmax tanker and a capesize bulker. This was followed by a presentation by ARCO Marine`s John Sullivan and Robert Levine, of the company`s twin-engine Millennium class tankers. Leo Cappoen is technical manager of Exmar and his paper was titled Redundancy a valuable option. Basic reliability a must. Another option, that of an auxiliary propulsion drive, was explored in the last paper of the conference by Mika Laurilehto and Terje Nordtun from Wartsila NSD.
Copies of the conference papers are available from The Motor Ship at an inclusive price of £180. Contact Claire Said, Fax: +44 181 652 8180.
