Wärtsilä to supply dual-fuel engines for China's first LNG powered tugs
(Thomson Reuters ONE) -
Wärtsilä Corporation, Press release, 11 July 2012, at 11.30 (EET)
Wärtsilä, the marine industry's leading solutions and services provider, is to
supply the main engines for two environmentally sustainable tugs being built for
CNOOC Energy Technology & Services Limited (CETS), a subsidiary of the state-
owned China National Offshore Oil Corp. (CNOOC). The vessels are the first in a
planned series to be fuelled by liquefied natural gas (LNG), and will be the
first tugs in China ever to be operated on gas. These will also be the first
tugs globally to take advantage of the dual-fuel benefits offered by the
Wärtsilä DF engine technology. The contract was signed in the beginning of July
2012 and the order is included in the third quarter 2012 order book.
The strategy of CNOOC is aimed at achieving more clean energy in its operations,
and the Wärtsilä dual-fuel engine solution fits this profile perfectly. The low
emission levels made possible by this technology is particularly beneficial for
vessels operating close to population centres, as tugs frequently are, while the
high fuel efficiency enables lower operating costs. These 6500 bhp 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.
The vessels will each be powered by two 6-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.
Wärtsilä dual-fuel (DF) engines
Wärtsilä's advanced dual-fuel technology was first launched in the early 1990s
for use in land-based power plant applications. The first marine installation
came a decade later. The technology enables the engine to be operated on either
natural gas, light fuel oil (LFO), or heavy fuel oil (HFO), and switching
between fuels can take place seamlessly during operation, without loss of power
or speed. This ensures safety and continuous installation operability. Wärtsilä
DF engines are designed to have the same output regardless of the fuel used.
The fitting of Wärtsilä DF engines onboard the first LNG Carriers in 2006 set a
trend in the industry. Since that introduction, 65 percent of all new LNG
Carriers have been fitted with Wärtsilä dual-fuel engines. One of the reasons
for the strong success of this particular engine over the alternatives is its
superior propulsion efficiency. The clear environmental advantages that
operating on gas allows, is another factor in the success of this technology.
When operating in gas mode, the nitrogen oxide (NOx) emissions are at least 85
percent below those specified in the current IMO regulations, and CO2 emissions
are some 25 percent less than those of a conventional marine engine running on
diesel fuel. Additionally, the sulphur oxide (SOx) and particle emissions are
negligible at almost zero percent.
Wärtsilä has recently achieved the notable milestone of supplying dual-fuel
propulsion engines to 100 Liquefied Natural Gas (LNG) Carrier vessels. As of end
May, Wärtsilä has sold some 720 DF engines, and has accumulated more than 5
million running hours of experience with this technology.
