MAN Energy Solutions has won the order from Oman Liquefied Natural Gas LLC (Oman LNG) to equip a new power plant with nine MAN 51/60 gas engines. The power plant will be located in Qalhat, southeast of Muscat on the Gulf of Oman, and will provide 120 MW of power to the existing LNG facility of Oman LNG. It will replace an existing gas-turbine plant. In fact, this market segment has been completely dominated by gas turbines in the past, so this is a pioneering installation that will show MAN 51/60 gas engine is the ideal fit for this application.
The new power plant needs to be capable of using a variety of differing gas compositions and methane numbers with limited gas conditioning or blending. To master this, MAN Energy Solutions has developed control strategies to ensure that the engines adapt to the prevailing gas configuration in real time for optimum performance.
As fuel, the new plant uses gases derived from the liquefaction process, which can contain high inert components in the fuel and, therefore, may have much lower calorific values. Thanks to their customized design, the engines will nevertheless be able to provide the required power, even at ambient temperatures of up to 48 °C.
Compared to the existing plant, MAN engines will significantly reduce fuel consumption and GHG emissions of Oman LNG’s Power Plant , while the modular-design approach guarantees top-of-the-line overall availability.
