Wärtsilä introduces game-changing 2-stroke dual-fuel engine technology
(Thomson Reuters ONE) -
Wärtsilä Corporation, Press release, 12 November 2013 at 11:00 am EET
Wärtsilä, the marine industry's leading solutions and services provider, has
successfully conducted full scale testing on gas of its low-speed 2-stroke dual-
fuel engine and is now introducing a full new range of engines based on its
established and well-proven low pressure technology. The implications of this
for ship owners and operators are such that the new engine is already being
referred to as a game-changer for merchant shipping. The first engine utilising
this technology, the Wärtsilä RT-flex50DF, will be available for delivery in the
third quarter of 2014. Other engines from the company's new Generation X series
will follow and will be available for delivery during 2015 and 2016.
Offering a broad range of benefits
The entire portfolio of Wärtsilä 2-stroke engines will be available as low
pressure dual-fuel (DF) versions. The benefits of this technology are
significant. Compared to other technologies, studies show that Wärtsilä's low
pressure DF engines offer capital expenditure (CAPEX) reductions of 15-20 per
cent. This is achieved through a substantially simpler and lower cost LNG and
gas handling system operating at pressures below 10 bar, and by the fact that no
further exhaust gas cleaning systems are needed to meet future emission
regulations. The new engines are IMO Tier III emissions compliant in gas mode,
and the minimum Tier II level is achieved with liquid fuel.
Furthermore, on the operating expenditure (OPEX) side, significant gains will be
achieved with Wärtsilä's technology. This is because no high pressure gas
compression system external to the engine needs to be operated onboard the
vessel, and NOx abatement systems are not required. Another main advantage is
that the Wärtsilä technology allows stable operation on gas across the entire
load range. This means that at low loads, there is no need to switch to diesel
fuel as is the case with other technologies. Moreover, the consumption of pilot
fuel is approximately just one per cent of the total fuel amount, and therefore
much lower than with other technologies.
Wärtsilä's low pressure gas system fulfils all safety requirements. Since low
pressure gas technology is the standard for all 4-stroke engine makers today,
the merit of this concept is clearly proven.
"The benefits of the new low pressure dual-fuel technology for 2-stroke engines
are significant. Describing this as a game-changing development for merchant
shipping is certainly no exaggeration, since the many advantages of being able
to use gas and LNG as primary fuel are now, for the first time ever, available
to virtually all vessel types. Our well proven technologies for both the engines
and the onboard gas and LNG handling systems, can now be applied to this wider
market. With the adaption of low pressure dual-fuel technology to 2-stroke
engines, Wärtsilä brings the proven advantages it has demonstrated in the 4-
stroke, medium-speed DF engine market to its 2-stroke low speed engine
customers," says Mr Martin Wernli, Vice President, 2-stroke, Wärtsilä Ship
Power.
Leading in dual-fuel engine technology
Wärtsilä has pioneered the development of dual-fuel engine technology, and is
today the industry leader in this field. Throughout the years, Wärtsilä's R&D
work has focused heavily on these technologies. Wärtsilä successfully introduced
its low pressure dual-fuel engine technology for 4-stroke engines for land based
applications in the 1990s, and for marine applications soon afterwards. Since
then, the company has delivered more than 1,000 such dual-fuel engines
accumulating more than 7 million running hours.
The application of natural gas as a widely accepted fuel for merchant shipping
is likely to become a reality in the near future. The environmental benefits and
attractive pricing that gas offers are expected to drive demand, with a
resulting increase in market share for gas fuel. By introducing low pressure 2-
stroke DF engine technology, Wärtsilä is accelerating this major trend since it
makes the application of gas as a marine fuel easier and safer for owners,
operators and yards. Wärtsilä envisages that by 2020, more than a quarter of the
ordered vessels could be designed to run on gas fuel.
Wärtsilä is currently in the process of finalising the documentation for the
first of the new series of engines, the Wärtsilä RT-flex50DF. Preparations for
Classification Society approvals are underway.
