Cleanship Marine carries out underwater propeller super polishing at Mundra 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 Mundra: it runs at high relative velocity, so roughness there costs disproportionately more than the same roughness spread over the hull. For the large container ships, capesize and panamax bulk carriers, crude and product tankers 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 Mundra
Mundra takes some of the largest tonnage calling anywhere in India, so a hull clean here is a big-area job that needs realistic planning rather than an optimistic single shift. The Gulf of Kutch tidal stream is strong and the water silty, so windows are worked around slack and visibility is low throughout. Terminal windows are tight and productivity-driven, which means the scope and the crew size are fixed before mobilisation and any contingency is agreed in advance, not negotiated at the gangway.

- Large container ships · Capesize and Panamax bulk carriers · Crude and product tankers
What we do at Mundra
- 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 Mundra Port and the 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 Mundra
The south-west monsoon governs the calendar at Mundra 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. The tidal stream and the silt load govern the method here: the working window is slack water, not the working day, and the operation is planned by feel and surface supervision with video kept as the record rather than as the diver's means of navigation.
Work is taken at the container terminals, bulk and coal berths, liquid terminals, outer anchorage, and which of those a vessel ends up at changes the dive plan more than the season does. Teams mobilise via Mundra or Bhuj (BHJ), 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 Mundra
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 Mundra than owners budget for.
Silt settles over the growth on the flat bottom and in the niches, which masks the true fouling state until the divers are actually on it. That is why the pre-clean survey here is a real step rather than a formality.
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 Mundra
- 1
Scope and vessel details
Tell us the vessel, her particulars, the coating specification and the window at Mundra. 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 Mundra Port and the 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 Mundra
Divers, compressors, brush carts and cameras mobilise via Mundra or Bhuj (BHJ). 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 Mundra
Do you provide propeller polishing at Mundra Port?
Yes. Cleanship Marine works Mundra Port (INMUN) in Gujarat, India, covering the container terminals, bulk and coal berths, liquid terminals, outer anchorage. Teams mobilise via Mundra or Bhuj (BHJ) with the full spread.
Can propeller polishing be done while the vessel works cargo at Mundra?
Usually yes, but the tide sets the schedule rather than the cargo plan. The practical question is how many slack windows fall inside the vessel's stay, not what the holds are doing. The vessel stays on hire throughout, and there is no diversion and no dry dock. We scope against the conditions at Mundra and tell you honestly whether the window you have is enough.
Do you need a diving permit from Mundra Port and the Gujarat Maritime Board?
Yes, and we obtain it. Diving permission from Mundra Port and the 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 Mundra?
Visibility at Mundra Port is habitually very low, and often close to nil at the turn, 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 Mundra?
Large container ships, Capesize and Panamax bulk carriers, Crude and product tankers — the traffic at Mundra Port runs to containers, thermal coal, crude and pol, 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 Mundra?
Divers and equipment mobilise via Mundra or Bhuj (BHJ). 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 Navlakhi, one mobilisation is often sized to cover both.
What does propeller polishing at Mundra cost?
It depends on the vessel's dimensions and wetted area, the fouling state found, the coating specification and the working window available at Mundra. 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 Mundra and you get a scoped price, usually the same working day.
