EnviroEngines for Queen Mary 2
Wärtsilä 46 EnviroEngines totalling 67.2 MW power output will. supply the diesel component of the CODAG (combined diesel and gas turbine) power plant in Cunard Line's Queen Mary 2. These engines will incorporate common-rail fuel injection technology for operation without visible smoke.
Due for delivery in late 2003 by Chantiers de l'Atlantique, Saint Nazaire, France,Queen Mary 2 will be the world's largest passenger vessel. Measuring 345 m long by 40 m beam and drawing 10 m, the 150,000 grt liner will have a maximum speed of about 30 knots.
Electrical power for propulsion and all shipboard services will be generated by a 115.5 MW CODAG plant. Propulsion will be by four electrically driven Rolls-Royce Mermaid podded drives, two fixed and two azimuthing.
The four Wärtsilä 16V46 EnviroEngines will be manufactured at Wärtsilä's Turku factory in Finland. They are due to be shipped in June 2002. The engines will each have a maximum continuous output of 16,800 kW (22,840 bhp) at 514 rev/min. For redundancy, the diesel generating sets will be housed in two separate engine rooms.
The Wärtsilä EnviroEngine arose from a joint project between Carnival Corporation, the parent company for Cunard Line, and Wärtsilä Corporation to develop a new "earth-friendly" power system. The Wärtsilä 46 EnviroEngines use an electronically-controlled common rail fuel injection system that enables injection pressures to be kept sufficiently high at all engine loads and speeds - even at the lowest levels - to achieve clean combustion with no visible smoke emissions. The EnviroEngines will be particularly beneficial for use in port, as they are designed to produce no visible emissions even when lightly loaded for producing energy for lighting, air conditioning and other hotel systems.
In common with other Wärtsilä diesel engine types, the EnviroEngines meet current limits for NOX emissions. In addition, their good fuel economy results in lower CO2 emissions.
EMFF makes safety awards
ExxonMobil Marine Fuels (EMMF) has paid tribute to the vital contribution made to its flawless safety record by its staff and by a network of contractors throughout the world.
EMMF is the world's largest supplier of marine fuels. It has a supply presence in over 300 ports in more than 70 countries, through which more than 15 million tonnes of marine fuel are supplied annually. Last year it operated with an unblemished record - no fatalities, no lost time, no recordable incidents, no delivery vehicle accidents, no spills.
Joe Rud, general manager of fleet purchasing, business development and e-commerce at EMMF, says, "We are very proud of our record. To perform over 18,000 individual truck and barge operations without incident, as EMMF did last year, confirms the high priority we place on safety. Our aim has always been to achieve the highest quality product, the optimum level of service, and the most competitive price without compromising safety. The fact that we have been able to achieve that is a tribute to our staff, and to the contractors who work with us around the world. Their contribution is invaluable."
To recognize this contribution, safety awards have been presented by EMMF in the past few month to 35 contractors in as many different countries.
EMMF achieved the top award for best safety performance in ExxonMobil's global Fuels Marketing operations as a result of its flawless performance in 2000. Performance year to date 2001 has remained at this consistent high standard.
