The aircraft's maximum output power is 21,660 kW (294,48 hp) and will be assembled on a 210,000-ton bulk carrier built by Bohai Shipbuilding Heavy Industry Co., Ltd. for Singapore Global Shipping.
The W6X72 is the latest intelligent mainframe launched by Wärtsilä in 2012. Since its inception, its green and low-cost operation has been well received by shipowners. 90% of the parts of the model have been optimized for compactness, light weight, easier assembly, more reliable operation, more flexible operation and longer overhaul. In terms of environmental protection, the W6X72 is equipped with a new FAST injector to reduce fuel consumption by at least 1-2g/kW.h. The UNIC control system used in the machine can realize timed fuel injection and exhaust valve switching, further reducing fuel consumption. At the same time, the machine reduces pollutant emissions in the full load range, achieves smoke-free operation, and meets the International Maritime Organization's TII emission standards.
In order to complete the construction of the W6X72 machine with high quality, Dalian Shipyard summed up the experience of producing intelligent mainframes in the past, and put all the difficulties in the forefront to prepare for the production. After the start-up order was issued, due to incomplete drawings, the technical department used the 6RT-flex68-D mainframe as a reference to organize the workshops of the W6X72 mainframes, and to express the special requirements of the shipyard owner to the host, so that everyone can New designs, new processes, and new requirements are understood. Suggestions for key issues such as new consoles, oil systems, and cold water systems to be used in production are needed to advance the preparations for various departments and lay the foundation for the smooth construction of the mainframe.
The W6X72 mainframe is the 158th intelligent mainframe delivered by Dalian Shipai to customers. Since the successful delivery of the world's first 7RTflex58T-B machine in August 2005, Dalian Shipai has been committed to the introduction and development of intelligent and environmentally friendly mainframes, and has been closely cooperating with MAN and W?RTSIL? It has successfully tested the world's first intelligent mainframes such as 6S50ME-C, 6RT-flex68-D and 7RT-flex58TB, and equipped the 7RT-flex84TD mainframe for the largest ships in China, replacing the traditional models for intelligent main engines and promoting the world's diesel engine manufacturing. The historic revolution of the industry has made outstanding contributions.
At present, Dalian Shipai's follow-up orders are all intelligent mainframes, which have been mass-produced. Facing the future, Dalian Shipai will always be firm in its development goals. This is: the product level must always represent the international advanced level, providing high-quality high-power low-speed diesel engines to global users, adding the most reliable power to the world's shipping.
