Drydock & Afloat Repairs

Are you searching for a trusted partner to thoroughly inspect, identify and rectify potential problems during the critical drydocking period?

The drydock period is perhaps the most stressful time for technical managers and owners. A successful drydock ensures the vessel’s future smooth operation, prevents unforeseen breakdowns, and provides peace of mind to the owners. 

As such, drydock preparation and execution is a complex exercise that involves budgeting, choosing the right shipyard and contractors, smooth coordination of all involved parties, careful planning, and a vigilant eye during the execution of all drydock works.

CPP Systems Overhauling

CCP systems (Controllable Pitch Propellers) are systems in which the blades are bolted to the boss. A hydraulic system can alter its pitch, allowing the vessel to adjust load and speed depending on the operational requirements faster response and efficiency.
One can find these systems in passenger and specialized vessels. Although they bring considerable advantages, they are also more complicated than fixed propeller systems and have higher maintenance requirements.

Bow & Stern Truster Overhauling

Thrusters are systems consisting of propellers, gearboxes, and electric or hydraulic motors located at the bow or stern of a vessel, allowing higher ship maneuverability during berthing operations. 
Thrusters are usually found in container carriers or special vessels and minimize the need for tug assistance, thus saving money for vessel owners. 
Our extensive experience in maintaining bow and stern thrusters of all makes, including KAWASAKI, Rolls Royce, Bergen, and others.

We can offer a comprehensive range of maintenance and repairs services, including :  

  • Overhauling and repairs on thruster blades
