A rough or fouled propeller surface increases hydrodynamic drag, raises fuel consumption, and adds load to the main engine. Studies show a polished propeller can recover 3–6% fuel efficiency compared to a fouled one. Oceanus Marine's underwater propeller polishing service in Singapore restores propeller surface finish in-water — no dry dock required.

What Propeller Polishing Covers

Our experienced commercial divers carry out full underwater propeller cleaning and soft cleaning to remove barnacles, marine growth, scale, and surface oxidation from all blade faces and edges. This is followed by mechanical polishing using specialist underwater grinding tools to restore blade surface smoothness to class-accepted standards. Underwater photo and video inspection is conducted before and after to document condition and confirm results.

Propeller Inspection and Repair Services

Polishing is combined with a full propeller inspection and condition survey. Our divers assess blade edges for nicks, cavitation erosion, and deformation. Where damage is found, we carry out in-water propeller shaping and grinding to restore blade geometry, and rope and entanglement removal from propeller shafts. Propeller Boss Cap Fins (PBCF) replacement and shaft anode replacement are available within the same dive where required.

Bundled With Hull and Vessel Cleaning

Propeller polishing is routinely scheduled alongside underwater hull cleaning and thruster maintenance to maximise efficiency gains from a single port call. For vessels on New Zealand MPI or Australia standard compliance routes, propeller and niche area cleaning is part of the mandatory pre-departure scope. Our commercial diving team in Singapore operates around the clock to fit vessel schedules with minimal off-hire impact.
