The United Arab Emirates (UAE) is one of the most important maritime and industrial hubs in the Middle East, handling large volumes of marine traffic, offshore operations, power generation projects, and industrial activities. RA Power Solutions has undertaken several crankshaft grinding, crankshaft repair, engine maintenance jobs, including in situ crankshaft grinding repair in UAE for ship owners, offshore companies, power plants, and industrial establishments.
We have more than 46 years of experience in onsite machining and engine repair services, and specialize in performing the repairs on site without dismantling the crankshaft or removing the equipment. This greatly reduces downtime, transportation costs, and operational losses.
We have experienced technicians & engineers all over UAE for emergency breakdown service and planned maintenance assignments.
