In December, Wärtsilä expanded its engine portfolio with two new auxiliary engines, the Wärtsilä Auxpac 16 and the Wärtsilä Auxpac 32. The new engines offer a high level of reliability and are compliant with the IMO’s Tier II environmental regulations. Their launch is an important step in strengthening Wärtsilä’s presence in the auxiliary engine market. Also in December, Wärtsilä launched its new 2-speed marine gearbox. The product, which will serve vessels with multiple operational modes or reduced transit speeds, offers notable economic and environmental benefits. Compared to a single mechanical propulsion system, a fuel consumption reduction of eight percent was verified with Wärtsilä’s 2-speed gearbox during sea trials.
In November, Wärtsilä introduced its new low-speed dual-fuel engine technology. The benefits of this technology include capital expenditure reductions through a substantially simpler and lower cost LNG and gas handling system. Furthermore, the new engines are compliant with IMO Tier III emission requirements in gas mode. The first engine utilising this technology, the Wärtsilä RT-flex50DF, will be available for delivery in the third quarter of 2014.
In October, Wärtsilä released its Wärtsilä 20DF dual-fuel engine for sale in the US market. The engine meets the United States Environmental Protection Agency’s strict Tier 4 emission requirements. A new series of steerable and transverse thrusters was also introduced. The new thrusters have been developed in response to changing market demand, which requires competitive products that are more efficient and that cover a wider power range. Wärtsilä also launched a new Bio Seal Ring™ product for maritime stern tube seal applications. The seal ring is the first in the market that works with environmentally acceptable lubricants for a lifetime of at least five years.
A new version of the Wärtsilä 34DF engine was launched in June. The engine offers increased power output and increased efficiency in both liquid and gas operating modes, as well as lower fuel consumption and improved environmental performance.
In March, Wärtsilä launched a unique product, the Wärtsilä GasReformer, which uses steam reforming technology to convert associated gas to a quality that can be used as fuel in Wärtsilä’s range of gas fuelled engines. Traditionally such gases would be flared and wasted.
