Switzerland-based Wärtsilä has reported that its X72 mid-bore, low-speed engine has passed the factory acceptance test conducted at the Doosan Engine factory in South Korea.
The factory acceptance test assesses the engine’s performance and against criteria for acceptance by the customer and the Lloyd’s register of shipping classification society.
Wärtsilä Switzerland managing director and two-stroke Wärtsilä Ship Power vice-president Martin Wernli said this is an important milestone for the company, as it is the first Wärtsilä X72 engine to be produced.
“The fact that it has successfully fulfilled the factory acceptance test requirements means that in every respect it meets our expectations, as well as the expectations of our customers,” Wernli said.
The Wärtsilä X72 engine is built using the company’s electronically time-controlled common-rail technology.
Designed in accordance with the energy efficiency design index (EEDI), the engine features a flexible fuel injection and exhaust valve operation that reduces fuel consumption and lowers the levels of exhaust emissions, including carbon dioxide and nitrogen oxide.
The Wärtsilä X72 engine can be fitted in a broad range of ship types including Capesize bulk carriers, Suezmax tankers and Feeder/Panamax container ships.
The successful completion of this first engine has caused Wärtsilä to increase the production of Wärtsilä X72 engines.
The next engine factory acceptance test is scheduled in February 2014.
