Wärtsilä Auxpac 20
This is a range of medium-speed generating sets running on heavy fuel oil, and based on Wärtsilä 20 engines.
The Auxpac auxiliary generating sets are supplied as pre-engineered and pre-commissioned standard packages. The common base-frame is optimized for the package, which together with the compact design of the engine and the selected generator, offers unmatched power-to-space and power-to-weight ratios.
The Wärtsilä Auxpac generating sets ensure the availability of electrical power in sufficient quantity, as and when it is needed. They cover an electrical power output of 500 to 2,800 kWe for either 50 or 60 Hz operation.
Through modularization, the generating sets can be built to high, comprehensive specifications at a competitive price. Wärtsilä Auxpac generating sets provide easy installation, easy operation, and low operating costs. Other benefits of pre-engineering include readily available documentation, including models in Tribon® format, and short lead-times.
Wärtsilä provides project management and experienced marine engineering to support the design and installation. Installation and commissioning procedures are standardized and well documented, which reduces the risk of shipyard errors. Auxpac generating sets are offered only as 400V/690V– 50Hz and 450V/690V–60 Hz in the power range 500 kW to 2800 kW.
Wärtsilä is continuously developing its products to achieve high environmental performance. The Wärtsilä Auxpac generating sets comply with IMO Tier II MARPOL Annex VI regulations and are supplied with an EIAPP Statement of Compliance.

The 'HMS Queen Elizabeth' is expected to enter service between 2019 and 2023. The prime movers selected for the generating sets are two 12-cylinder and two 16-cylinder Wärtsilä 38 engines for each ship. »
The luxury yacht ‘SAMAR’ was launched in 2006. The ship is powered by a diesel-electric propulsion system consisting of three Wärtsilä diesel generators and two drive motors with twin Wärtsilä fixed-pitch propellers. »
