First Stationary Successes for MAN Diesel’s 51/60DF
The new 51/60DF dual-fuel gas engine from MAN Diesel has now passed its second major milestone in electrical power generation applications. Following on the handover of a heavy fuel engine retrofitted to full 51/60DF specification at an existing cogeneration installation in Portugal, MAN Diesel Australia has booked the first order for new 51/60DF engines in a power plant application.
The turnkey contract has a value of US$39 million and covers the design and construction of a new 22 MW power station at Owen Springs, for Power and Water Corporation (PWC), an Australian public utility. The Territory’s PWC is a Northern Territory Government owned corporation and services more than 80,000 customers and has 360 MW of existing power generation capacity.
The new Owen Springs Power Station will be based on two 10.9 MWe generator sets, each powered by a 12-cylinder, Vee-configuration 12V 51/60DF engine. The generator sets will supply baseload power to the local grid in their gaseous fuel mode, i.e. burning natural gas ignited by a distillate fuel “micropilot”. At 500 mg /mn3 at 5% O2 on gaseous fuel, the 51/60DF readily achieves emissions of oxides of nitrogen (NOx) in compliance with both Germany’s TA Luft clean air regulations and the World Bank Pollution Prevention and Abatement Handbook, according to MAN.
As well as the supply, installation and commissioning of the generator sets, the scope-of-supply comprises all engineering work including civil and structural works; supply and installation of all electrical equipment and the plant control and monitoring system; all auxiliary systems including cooling radiators and supplementary cooling towers to cope with the design ambient temperature of 40°C; project management; and the necessary logistical arrangements. Construction is due to start in the near future and completion of the first stage of the project is scheduled for April 2009, with final completion in 2010.
