Wärtsilä Corporation delivered the first two Wärtsilä Auxpac generating sets in April 2005. Introduced in September 2004, Wärtsilä Auxpac is a standard, pre-commissioned generating set designed to provide auxiliary electricity onboard marine vessels. The new concept, with its key advantages of fast and easy installation, proven reliability, and easy maintenance, has already proved highly popular. To date Wärtsilä has more than 200 Wärtsilä Auxpac generating sets on order, some 70 of which are destined for China.
The first two Wärtsilä Auxpac 20 generating sets, both of 6-cylinder configuration, were supplied from the Wärtsilä factory in Vaasa, Finland to Shanghai Zhenhua Port Machinery Co Ltd, China, for installation on a new 4000-tonne heavy-lifting ship being built at the Jing Jiang Eastern Shipyard for Guangzhou Salvage Bureau (under MOC). The vessel measures 167.5 m long overall, 165 m long BP, 48 m in breadth, and 16 m deep, with a draught of 11.5 m. The heavy lifter will be delivered in April 2006. Several other Chinese companies are reported to be considering building similar vessels.
Wärtsilä will also deliver three 6-cylinder Wärtsilä 32 main engines for diesel-electric propulsion for the same vessel as well as two Lips steerable thrusters of 1500 kW each for propulsion running in Lips HR nozzles, and one Lips tunnel thruster. This propulsion package was ordered last autumn.
Features of Wärtsilä Auxpac
Wärtsilä Auxpac is a pre-commissioned standardized generating set based on a modular design. Its purpose is to ensure the availability of sufficient shipboard electrical power when needed. Typical applications include general cargo and container vessels, tankers and VLCCs.
Wärtsilä Auxpac generating sets are supplied in medium-speed and high-speed configurations with outputs from 60 to 2850 kWe for either 50 or 60 Hz operation. The medium-speed range covers an output range from 520 to 2850 kWe and the high-speed range from 60 to 1630 kWe.
The medium-speed generating sets, running on heavy fuel oil, are based on Wärtsilä 20 and 26 engines. These engines are well proven in shipboard auxiliary service and are supplied for operation on the same heavy fuel oil as the ship’s main engines. The high-speed Wärtsilä Auxpac range, running on marine gas oil, is based on co-operation with Volvo Penta through which Wärtsilä will sell and service large Volvo Penta engines for commercial shipping applications.
Wärtsilä Auxpac generating sets are delivered ready for installation. They are fully outfitted with all necessary ancillary equipment such as pumps, electrical and control systems. The generating sets are put through a well-defined factory-acceptance test which can also include parallel running when multiple sets are being supplied.
The generating sets are designed for resilient mounting in the ship’s hull for easy installation and alignment and for lower structure-borne noise.
Wärtsilä provides project management and experienced marine engineering to support installation of the Wärtsilä Auxpac as well as full service support including commissioning, maintenance and spare parts. This includes complete kits of original spare parts for easy service and maintenance onboard.
As with all Wärtsilä products, the Wärtsilä Auxpac generating sets are supported round the clock by Wärtsilä’s worldwide service organization with more than 6000 professionals.
