Cleanship Marine carries out underwater propeller super polishing at Okha Port, Gujarat. 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 alongside or at anchor.
The propeller is the highest-leverage surface on any vessel calling at Okha: it runs at high relative velocity, so roughness there costs disproportionately more than the same roughness spread over the hull. For the handysize bulk carriers, coastal tankers, barges and support craft 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 Okha
Okha lies at the western entrance to the Gulf of Kutch, where the water is noticeably clearer than at the head of the gulf and inspection video is genuinely usable. Tidal streams through the entrance are still strong, so dives are worked to slack. Depth alongside is limited, so larger tonnage is worked at anchor off the port rather than at the jetty.

- Jetty berths · Anchorage off the port
- Vessels we see here
- Handysize bulk carriers · Coastal tankers · Barges and support craft
What we do at Okha
- 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 Gujarat 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 Okha
The south-west monsoon governs the calendar at Okha 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. Water clarity here is good by regional standards, so the operation can be properly documented on video as it happens — an advantage that turns a cleaning job into usable condition evidence at no extra mobilisation cost.
Work is taken at the jetty berths and anchorage off the port, and which of those a vessel ends up at changes the dive plan more than the season does. Teams mobilise via Porbandar (PBD) or Jamnagar (JGA), 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 Okha
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 Okha than owners budget for.
Clearer water means the fouling state can be assessed properly before any tooling is selected, and the assessment can be shown to you rather than described.
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 Okha
- 1
Scope and vessel details
Tell us the vessel, her particulars, the coating specification and the window at Okha. 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 Gujarat 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 Okha
Divers, compressors, brush carts and cameras mobilise via Porbandar (PBD) or Jamnagar (JGA). Where a vessel is also calling at Kandla, 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 Okha
Do you provide propeller polishing at Okha Port?
Yes. Cleanship Marine works Okha Port (INOKH) in Gujarat, India, covering the jetty berths and anchorage off the port. Teams mobilise via Porbandar (PBD) or Jamnagar (JGA) with the full spread.
Can propeller polishing be done while the vessel works cargo at Okha?
Yes. Conditions here are good enough that the dive runs alongside cargo operations without either holding the other up, and the work is documented on video as it goes. The vessel stays on hire throughout, and there is no diversion and no dry dock. We scope against the conditions at Okha and tell you honestly whether the window you have is enough.
Do you need a diving permit from Gujarat Maritime Board?
Yes, and we obtain it. Diving permission from Gujarat 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 Okha?
Visibility at Okha Port is good by regional standards and usually adequate for video work, 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 Okha?
Handysize bulk carriers, Coastal tankers, Barges and support craft — the traffic at Okha Port runs to salt, bauxite and bentonite, 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 Okha?
Divers and equipment mobilise via Porbandar (PBD) or Jamnagar (JGA). 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 Kandla or Porbandar, one mobilisation is often sized to cover both.
What does propeller polishing at Okha cost?
It depends on the vessel's dimensions and wetted area, the fouling state found, the coating specification and the working window available at Okha. 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 Okha and you get a scoped price, usually the same working day.
