RA Power Solutions is an ISO 9001:2015-certified engineering company specialising in onsite crankshaft grinding, crankshaft repair, portable machining, diesel engine overhaul, metal stitching, engine reconditioning, and the manufacture and supply of marine engine components. With nearly five decades of engineering experience, we have successfully supported ship owners, power plants, offshore operators, and industrial facilities across the globe by delivering precision repair solutions that reduce downtime and restore critical equipment to reliable operating condition.
Our experienced engineers combine technical expertise with specially designed portable machining equipment to perform onsite repairs wherever possible, eliminating unnecessary dismantling and significantly reducing maintenance costs. Every repair assignment begins with a detailed inspection and engineering assessment to ensure the most appropriate repair procedure is selected while maintaining compliance with OEM specifications.
Established nearly five decades ago, RA Power Solutions has earned a strong reputation for delivering specialized onsite engineering services to the marine, offshore, power generation, and industrial sectors. Our expertise extends beyond crankshaft repair to complete diesel engine maintenance, metal stitching, white metal bearing services, engine overhauls, and the manufacture and supply of precision-engineered components.
We understand that equipment failure directly impacts production schedules, vessel operations, and maintenance costs. Therefore, our engineering solutions focus on restoring damaged components efficiently while minimizing operational interruptions. By combining practical field experience with advanced portable machining technology, we help customers extend equipment life and avoid unnecessary component replacement wherever technically feasible.
Our mission is to provide reliable, high-quality engineering solutions that improve equipment reliability, reduce operational downtime, and extend the service life of critical machinery. We are committed to delivering precision workmanship, transparent technical advice, and dependable onsite support for customers operating marine engines, industrial diesel engines, turbines, compressors, and other rotating equipment.
Every project is approached with a focus on safety, engineering accuracy, and long-term equipment performance.
Successful repairs begin with understanding the actual condition of the equipment rather than making assumptions. Every crankshaft, engine block, or rotating component is inspected carefully before any machining work is undertaken.
This systematic approach ensures repairs are carried out safely, accurately, and within permissible engineering limits.
Our engineers have completed repair assignments for customers operating critical diesel engines across a wide range of industries.
Our experience across diverse industries enables us to recommend repair solutions that are both practical and technically reliable.
Onsite crankshaft grinding is one of our core engineering services. Removing a crankshaft from a vessel or industrial engine can be costly and time-consuming. Whenever technically feasible, our engineers restore crankshaft journals directly at the installation site using specially developed portable crankshaft grinding machines.
This approach minimizes equipment downtime, reduces transportation costs, and allows repairs to be completed without unnecessary engine dismantling.
Crankshaft damage can occur due to bearing seizure, lubrication failure, contamination, overheating, overload, misalignment, or prolonged engine operation after wear begins. Every crankshaft is carefully inspected before the repair procedure is determined.
Our objective is to restore crankshaft geometry while maintaining dimensional accuracy and reliable engine performance.
Years of practical onsite repair experience have enabled RA Power Solutions to develop portable crankshaft grinding machines capable of precision machining in confined engine room environments.
Along with repair services, we manufacture and supply crankpin bearings suitable for marine propulsion engines, auxiliary engines, stationary diesel engines, and power generation equipment.
Bearing selection is based on crankshaft dimensions, undersized after grinding, operating conditions, and OEM recommendations.
Beyond crankshaft repair, we undertake complete diesel engine overhaul and maintenance projects for marine and industrial customers. Our services are designed to improve equipment reliability, reduce unplanned shutdowns, and restore engine performance.
Accurate inspection forms the foundation of every successful repair. Before machining begins, our engineers perform comprehensive dimensional checks to determine whether repairs can be completed safely within manufacturer specifications.
Where required, repairs are carried out in accordance with approved engineering procedures and documented for review by vessel owners, technical superintendents, OEM representatives, and classification societies. Detailed inspection reports, machining records, and dimensional measurements are maintained throughout the repair process.
RA Power Solutions is committed to maintaining high standards of engineering quality and customer service. Our operations are supported by recognized certifications and professional memberships that reflect our focus on quality management and international service standards.
