The power plant will be located in Qalhat, southeast of Muscat, and will provide 120MW of power to the existing LNG facility of Oman LNG. It will replace an existing gas-turbine plant.

“We are very proud to have been chosen for this exciting and technologically challenging project,” said Wayne Jones, chief sales officer of MAN Energy Solutions. “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, we have developed control strategies to ensure that the engines adapt to the prevailing gas configuration in real time for optimum performance.”

As a 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.

Hajo Hoops, senior sales manager at MAN Energy Solutions, added, “Compared to the existing plant, our engines will significantly reduce fuel consumption and GHG emissions of Oman LNG’s Power Plant, while our modular-design approach guarantees top-of-the-line overall availability. The robust design of our 20MW engine platform, the 51/60, is proven over millions of hours of operations all over the world and we are confident it will also perform well in Qalhat.”
