Cleanship Marine carries out underwater propeller super polishing at Pipavav 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 Pipavav: it runs at high relative velocity, so roughness there costs disproportionately more than the same roughness spread over the hull. For the container ships, pure car and truck carriers, bulk carriers 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 Pipavav
Pipavav is a sheltered all-weather port on the Saurashtra coast, with water clearer than the Gulf of Khambhat and Gulf of Kutch ports and a tidal stream that is manageable rather than governing. That combination makes it one of the more comfortable Indian ports for in-water class survey and UWILD work as well as for cleaning. Terminal windows on the container and RoRo berths are tight, so the scope is fixed before the divers mobilise.

What we do at Pipavav
- 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 Pipavav Port Limited, 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 Pipavav
The south-west monsoon governs the calendar at Pipavav 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 container berths, bulk berths, RoRo berth and anchorage, and which of those a vessel ends up at changes the dive plan more than the season does. Teams mobilise via Diu (DIU) or Rajkot (RAJ), 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 Pipavav
Liquid and gas tonnage here spends long stretches at the terminal or waiting for a slot, so growth tends to be even and well established across the hull rather than patchy — heavier than the trading pattern suggests, and further along than a speed report alone would indicate.
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 Pipavav
- 1
Scope and vessel details
Tell us the vessel, her particulars, the coating specification and the window at Pipavav. 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 Pipavav Port Limited, 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 Pipavav
Divers, compressors, brush carts and cameras mobilise via Diu (DIU) or Rajkot (RAJ). Where a vessel is also calling at Bhavnagar, 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 Pipavav
Do you provide propeller polishing at Pipavav Port?
Yes. Cleanship Marine works Pipavav Port (INPAV) in Gujarat, India, covering the container berths, bulk berths, RoRo berth and anchorage. Teams mobilise via Diu (DIU) or Rajkot (RAJ) with the full spread.
Can propeller polishing be done while the vessel works cargo at Pipavav?
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 Pipavav and tell you honestly whether the window you have is enough.
Do you need a diving permit from Gujarat Pipavav Port Limited?
Yes, and we obtain it. Diving permission from Gujarat Pipavav Port Limited, 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 Pipavav?
Visibility at Pipavav 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 Pipavav?
Container ships, Pure car and truck carriers, Bulk carriers, Product tankers — the traffic at Pipavav Port runs to containers, dry bulk, roro and automobiles, 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 Pipavav?
Divers and equipment mobilise via Diu (DIU) or Rajkot (RAJ). 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 Bhavnagar or Muldwarka, one mobilisation is often sized to cover both.
What does propeller polishing at Pipavav cost?
It depends on the vessel's dimensions and wetted area, the fouling state found, the coating specification and the working window available at Pipavav. 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 Pipavav and you get a scoped price, usually the same working day.
