Wärtsilä 31 engines for Russian icebreaker

The actual Wärtsilä Corporation has recently introduced that its Wärtsilä thirty-one engines have been selected in order to power an Aker ARCH 124 icebreaker being built at the PJSC shipyard within Vyborg, north-western Russia. Released at the 2015 Nor-Shipping 2015 exhibition in Oslo, the actual engine has set brand new levels for fuel effectiveness in addition to having reduced servicing needs and offering versatility in fuels used. In the diesel version, efficiencies up to 165g/kWh can be achieved, acknowledged as the records for a four-stroke diesel powered engine.
The engine style is entirely new as well as includes a range of advanced technologies features in fuel shot, engine control and cost air systems. These allow the delivery of canister powers of up to 610kW -- the highest in its market section - while achieving IMO Tier III emissions limitations. The modular construction additionally ensures maintenance times held to a minimum, meaning operator expenses and downtimes are decreased, with the first service period being at 8000 running hrs, compared with other standard sea engines requiring maintenance right after as little as 2000 hours.
The particular Wärtsilä 31 is available in Sixth is v configurations of 8, ten, 12, 14 and sixteen cylinders offering power results from 4. 2MW to be able to 9. 8MW, at 720 rpm and 750 rpm output speeds. Fuel choices include diesel, dual-fuel (DF) and spark-ignited gas (SG) with the multi-fuel capabilities furthermore enabling a range of fuel characteristics to be used, from light for you to heavy diesel oil and gas energy of a range of compositions and also qualities.
IMO Tier 3 emissions limits can be fulfilled when running on fuel fuel with no exhaust post treatment equipment. When running upon diesel fuel compliance may also be achieved with the addition of selective catalytic reduction and without any embrace fuel consumption. These enhancements are also matched by overall flexibility and significant reductions inside maintenance costs.
At the launch of the new engine, Roger Holm, senior vice president, Deliver Power Engines, Wärtsilä, stated: “Years of development function are have culminated within the introduction of the Wärtsilä 31st engine. With this breakthrough advancement, which is based on the introduction of the very most latest technology, we can now open up the doors to a new degree of optimisation that is valid car life of the vessel. ”
The 31 engine is actually targeted primarily at boat types such as anchor dealing with tugs, offshore supply ships and drilling and semi-submersible vessels, with requirements with regard to operational flexibility combined with higher power density. Also, inside the cruise and ferry field, the Wärtsilä 31 allows operators to reduce fuel fees while maintaining the high standards associated with environmental performance demanded.
With this latest icebreaker application, gas efficiency and reliability had been the major factors on which three eight-cylinder Wärtsilä 31 motors were selected. Other crucial considerations were operational flexibleness and the engine’s performance throughout extreme environmental conditions.
The brand new vessel, being built for FSUE Atomflot, the business of ROSATOM, the State Company for Atomic Energy, will certainly serve the Yamal LNG project in Sabetta, situated northeast of the Yamal peninsular in Russia, and run in temperatures down to less 50°C. The installation will even include Wärtsilä's online motor monitoring system, which will permit remote monitoring of powerplant operation, performance and problem, to ensure optimum performance with all times.
"We tend to be confident that this project is a success because of Wärtsilä's trustworthiness in the industry, and the positive encounter from our long set up partnership with this solutions supplier. ” said FSUE Atomflot first deputy director common - chief engineer Mustafa Kashka. “High vessel accessibility and fuel efficiency would be the key winning factors for just about any shipowner. The Wärtsilä thirty-one engines will facilitate a substantial improvement in vessel procedures, making it extremely competitive available on the market. This new icebreaker, powered through Wärtsilä 31 engines, would be the most technologically-advanced ship available in the whole world. "
