FPP Mobile Propeller Repair Workshop
Stone Marine Shipcare has recently developed two mobile workshops for rapid response to propeller repairs worldwide. These fully equipped workshops can be deployed at short notice anywhere in Europe by road transport, and worldwide, by shipping.
The mobile workshops allow service teams to be totally self-sufficient when attending shipyards that can often struggle to provide the necessary equipment required to carry out large propeller repairs.
Efficiency & Propeller Modifications
Bespoke propeller modifications, often carried out afloat, allow the vessel’s engine to operate within normal tolerances. These modifications reduce the engine loading and restore the Light Running Margin to reduce engine maintenance costs, improve fuel efficiency and provide a short pay-back period.

Stone Marine Shipcare works with Datum Electronics Ltd to fit torsion meters which allow vessel efficiency to be monitored.
