Propeller Repair & Replacement


BPM offers technically sophisticated solutions to propeller damage and associated performace problems via the One Ocean™ network. This network has been formed between UMC International, All-Sea Enterprises and Phoenix International to offer a global single common standard of service delivery.

Through this association, BPM is able to perform underwater 'shop quality' repairs, which, in many cases are considered as 'permanent' by the Classification Societies. The One Ocean™ network can now accomplish repairs underwater that, until recently, could be done only in propeller shops. BPM personnel have undergone extensive classroom and on-the-job training in propeller repair. This training has included operating specialized equipment and techniques that allow propeller blade straightening; mass in-balance correction and technical inspections.
