New Orders for Large Common-rail Engines
Sulzer RT-flex96C low-speed diesel engines have been ordered by Odense Steel Shipyard A/S in Lindø, Denmark, for installation in four 3700 TEU L-class container ships building there for the Danish group A.P. Møller - Mærsk, Safmarine and Deutsche Afrika Linien. The ships are due for delivery in 2004 and 2005. These are further examples of the most powerful diesel engines so far announced to have electronically-controlled common-rail fuel injection. The first Sulzer RT-flex96C engines were ordered in April 2003. The eight-cylinder engines will each develop 45,760 kW (62,240 bhp) at 102 rev/min. The engines will be built under licence from Wärtsilä Corporation by HSD Engine Co Ltd in Korea.
Commercial Marine Engine Emission Standards Finalized
EPA Administrator Carol Browner signed a final rule establishing new emission standards for commercial marine diesel engines at or above 37 kW (approximately 50 hp). EPA's final rule aplies emission standards to new engines only, beginning with the 2004 model year. Vessels and engines built before 2004 will not be subject to emission control requirements. However, if a vessel is subsequently modified such that 50 percent of the modified vessel's value is derived from new material or components, the vessel will be considered new and will be required to meet engine emission standards in effect at the time the modifications are made. EPA believes this will prevent companies from re-using parts from used vessels to avoid emission standards.

Playing the Tier Game
With few exceptions, marine power is diesel power and emissions levels from diesel engines are coming under increased scrutiny and regulations from the Environmental Protection Agency. The levels of acceptable NOx, carbon monoxide and particulate matter for diesel engines in U.S. flagged vessels depends on the displacement of the engine. The EPA has settled on a liters-per-cylinder measurement to determine the schedule to meet the emission requirements. For example, marine diesel engines between 1.2 and 2.5 liters per cylinder have had to meet what is known as Tier Two requirements since 2004. These are engines typically used to power small gensets, bow thrusters, fire pumps and other auxiliary engine requirements.
New Four-Cycle Marine Workboat Engine Package

New Volvo Penta Between Regular Runs
MF Vardehorn, a Norwegian car and passenger ferry, was having problems with one of its four propulsion engines. The contract to replace the engine was awarded to Marhaug A/S, Volvo Penta’s dealer in Svolvaer, Norway. The replacement, which involved cutting holes in the ship’s hull to install the new engine, was completed between two scheduled runs by the ferry. “We are extremely satisfied with the engine replacement and the manner in which Volvo Penta helped us solve our problem. The work was completed quickly, without requiring us to take the ferry out of traffic,” says shipping company inspector Jan Sletteng of TFDS, owner of the MF Vardehorn. Volvo Penta has been expanding its product program by including marine diesel engines with cylinder volumes ranging from 25 to 65 liters.
Entering A New Certification Era
Marine diesel engines have long been subject to classification society rules. However, from the start of next year, a whole new - and quite separate control regime will begin to take effect with major implications for both new and existing engines. Annex VI of MARPOL 73/78, dealing with a wide range of air pollution control matters (including ozone depleting substances, acid deposition materials, volatile organic compounds, incineration and oil fuel quality), is still some way from reaching the required level of ratification to enter into force. Nevertheless, the time is fast approaching when some of the provisions of that Annex will start to take effect. This is particularly true in terms of the oxides of nitrogen (NOx) controls, Regulation 13.
Wärtsilä's Engines Tested
