Cleanship Marine carries out underwater propeller super polishing at Belekeri Port, Karnataka. Divers work the blades through a multi-stage sequence to a Class A mirror finish, removing fouling, calcareous deposits and accumulated surface roughness while the vessel lies at the anchorage.
The propeller is the highest-leverage surface on any vessel calling at Belekeri: it runs at high relative velocity, so roughness there costs disproportionately more than the same roughness spread over the hull. For the handysize and supramax bulk carriers, lighterage barges and tugs working this port, polishing is the shortest route to a measurable fuel saving.
What it gets you
- Blade roughness removed where it costs the most, at the highest-velocity surface on the vessel
- Propeller efficiency restored between dockings without off-hire
- Cavitation erosion and edge damage documented before it becomes a repair item
- A finish record that supports hull and propeller performance monitoring
Working conditions at Belekeri
Belekeri is an open roadstead, so underwater work is done with the vessel riding to her anchor rather than alongside a berth. The south-west monsoon between June and September closes the practical season, and cleaning is planned into the fair-weather months either side of it. Visibility in the Arabian Sea here is workable outside the monsoon, but ore dust suspended around active lighterage cuts it sharply, so divers work up-current of the transfer barges wherever the anchorage allows.

- Outer anchorage · Lighterage transfer position
- Vessels we see here
- Handysize and Supramax bulk carriers · Lighterage barges and tugs
What we do at Belekeri
- Blade condition assessment covering both faces, the leading and trailing edges and the tips
- Multi-stage polishing sequence worked down to a Class A mirror finish
- Boss, hub and fairing cone cleaned, with rope guard and seal area inspected
- Edge damage, cavitation erosion and any deformation photographed and reported rather than polished over
- Diving permission cleared with Karnataka Maritime Board, and the shaft confirmed immobilised with the master before the dive
- Before-and-after video and a written finish record for the performance file
Planning the window at Belekeri
The south-west monsoon governs the calendar at Belekeri Port, roughly June to September. Swell and reduced surface visibility close most open-water work on this coast for the duration, and the weeks either side are unreliable rather than unusable. Work here is done with the vessel riding to her anchor, so the dive plan is built around sea state and swell rather than a berth slot, and the team stands by for a workable window rather than a scheduled one.
Work is taken at the outer anchorage and lighterage transfer position, and which of those a vessel ends up at changes the dive plan more than the season does. Teams mobilise via Hubballi (HBX) or Goa (GOI), so give us the ETA as early as you have it — the travel is the flexible part, the approvals and the working window are not.
What we typically find at Belekeri
Dry bulk handling here puts cargo dust into the water around the berths and anchorage. It settles on horizontal surfaces and packs into sea chest gratings and inlet openings, so inlet and grating clearance is routinely a larger part of the job at Belekeri than owners budget for.
Vessels here sit at anchor for long periods, and a stationary hull in warm water is the ideal fouling substrate. The heaviest growth we lift at this port is almost always off a vessel that has been waiting rather than working.
Standard scope of work
Included as standard on every propeller polishing attendance, wherever the vessel is. Anything outside it is quoted separately and flagged before mobilisation, never added afterwards.
- Deposit removal
- Calcareous growth, shell and hard deposits removed from both blade faces without gouging or scoring the blade surface.
- Progressive polishing
- Successive abrasive grades work the blade from rough to fine, finishing at a Class A mirror surface across the full blade area.
- Edge finishing
- Leading and trailing edges dressed to restore profile and remove the roughness that seeds cavitation.
- Boss and hub
- Boss, hub and rope guard cleaned, with stern tube seal condition inspected and reported.
How we deliver it at Belekeri
- 1
Scope and vessel details
Tell us the vessel, her particulars, the coating specification and the window at Belekeri. We come back with a defined scope, a crew size and a duration we will stand behind. Where the conditions here will not support what has been asked for, we say so at this stage rather than after mobilisation.
- 2
Permits and approvals
Diving permission is obtained from Karnataka Maritime Board, along with terminal approval where the berth requires it and any environmental clearance for in-water work. This is handled by us, not left with the agent to chase.
- 3
Mobilisation to Belekeri
Divers, compressors, brush carts and cameras mobilise via Hubballi (HBX) or Goa (GOI). Where a vessel is also calling at Karwar, one mobilisation is normally sized to cover both.
- 4
Safety setup and the dive
The vessel is secured for diving — main engine, shaft and thrusters immobilised, sea suctions confirmed shut, permit agreed with the master. Teams work under surface supervision with continuous diver communications and video throughout.
- 5
Report and handover
A completion report covering propeller polishing is issued with before-and-after imagery, coating and anode condition and anything found that you should know about. The findings are discussed with the vessel rather than emailed and forgotten.

Frequently asked — Propeller Polishing at Belekeri
Do you provide propeller polishing at Belekeri Port?
Yes. Cleanship Marine works Belekeri Port (INBLK) in Karnataka, India, covering the outer anchorage and lighterage transfer position. Teams mobilise via Hubballi (HBX) or Goa (GOI) with the full spread.
Can propeller polishing be done while the vessel works cargo at Belekeri?
Yes — it is the norm here, because the work is done at anchor rather than at a berth. Barge operations carry on around the dive, with the working side agreed with the master beforehand. The vessel stays on hire throughout, and there is no diversion and no dry dock. We scope against the conditions at Belekeri and tell you honestly whether the window you have is enough.
Do you need a diving permit from Karnataka Maritime Board?
Yes, and we obtain it. Diving permission from Karnataka Maritime Board, terminal approval where the berth requires it, and any environmental clearance for in-water work are arranged as part of the job rather than left with the agent. The master's permit to work and the immobilisation of machinery are agreed on board before anyone enters the water.
What is underwater visibility like at Belekeri?
Visibility at Belekeri Port is generally workable outside the monsoon, though cargo dust from lighterage reduces it sharply near an active transfer, and the south-west monsoon sets the outer limits of the calendar. How the tide and sea state shape the dive plan is set out in full in the working-conditions section on this page.
Which vessels do you carry out propeller polishing on at Belekeri?
Handysize and Supramax bulk carriers, Lighterage barges and tugs — the traffic at Belekeri Port runs to iron ore, manganese ore and bauxite, so those are the profiles we see most. The scope is sized to the vessel, not to a standard package.
How quickly can a team mobilise to Belekeri?
Divers and equipment mobilise via Hubballi (HBX) or Goa (GOI). Give us the ETA and the window and we will confirm what is achievable rather than promise a date we cannot hold. Where the vessel also calls at Karwar or Mormugao, one mobilisation is often sized to cover both.
What does propeller polishing at Belekeri cost?
It depends on the vessel's dimensions and wetted area, the fouling state found, the coating specification and the working window available at Belekeri. We would rather scope it properly and give you a specific figure than quote a headline rate that changes once the work starts. Send the details and the window at Belekeri and you get a scoped price, usually the same working day.
