Wärtsilä 34DF engines have been selected for China's first gas-fuelled tugs

Wärtsilä says that it is to supply the main engines for two LNG-fuelled tugs being built for CNOOC Energy Technology & Services (CETS), a subsidiary of the state-owned China National Offshore Oil Corp (CNOOC).

The vessels will each be powered by two six-cylinder Wärtsilä 34DF in line dual-fuel engines. Delivery is scheduled at the beginning of 2013, and the first of the tugs is expected to be delivered in June 2013. The two tugs are the first in a planned series to be fuelled by LNG, and will be the first tugs in China to be operated on gas. These will also be the first tugs globally to use Wärtsilä’s dual-fuel engine technology. The contract was signed in the beginning of July 2012.

According to Wärtsilä, the strategy of CNOOC is aimed at achieving cleaner energy use in its operations, and the dual-fuel engine solution fits this profile. The low emission levels made possible are particularly beneficial for vessels operating close to population centres, as tugs frequently do, while the high fuel efficiency enables lower operating costs. These 6,500bhp tugs will operate along China's coastline, and will be fuelled from the company's own bunkering terminals.

"We are delighted to be co-operating with CNOOC in supplying the main engines for these gas fuelled tugs. It is a landmark project that is very much in line with the marine sector's key targets of achieving greater sustainability with better fuel efficiency. We endorse CNOOC's strategic move towards cleaner energy and the use of LNG as a marine fuel, which is precisely in line with Wärtsilä's own strategy," says Aaron Bresnahan, vice-president Wärtsilä Ship Power specials.
