RA Power Solutions has been undertaking the overhauling of main engines and auxiliary engines installed on board a vessel or land-based engines used for different applications. We also undertake onsite repair of crankshafts and major engine components.

During our work on diesel engines, we have observed that customers face a lot of problems in the procurement of genuine and high-quality spares. In some cases, the marine engine spares of the main engine and auxiliary engines are not available as production of a particular model of engine has been discontinued by the manufacturer of the engine.
