Cleanship Marine carries out underwater propeller super polishing at Kandla 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 Kandla: it runs at high relative velocity, so roughness there costs disproportionately more than the same roughness spread over the hull. For the product and chemical tankers, bulk carriers, general cargo ships 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 Kandla
Kandla sits at the head of a creek off the Gulf of Kutch, where tidal streams run hard and the water carries a heavy silt load. Dive windows are worked to slack water and visibility is low, so cleaning is executed by touch with continuous surface supervision and video kept as the record rather than as the diver's guide. Vessels frequently wait at the outer anchorage before a berth slot comes free, and that waiting time in warm gulf water is where most of the fouling is picked up.

What we do at Kandla
- 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 Deendayal Port Authority, 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 Kandla
The south-west monsoon governs the calendar at Kandla 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 Kandla creek berths, oil jetties and outer anchorage, and which of those a vessel ends up at changes the dive plan more than the season does. Cleanship holds an operating base at Kandla, so we can hold a team ready against a shifting ETA rather than committing travel to a date that may move.
What we typically find at Kandla
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.
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 Kandla
- 1
Scope and vessel details
Tell us the vessel, her particulars, the coating specification and the window at Kandla. 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 Deendayal Port Authority, 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 Kandla
Cleanship holds an operating base at Kandla, so divers, compressors, brush carts and cameras are on the ground rather than in transit. That is the difference between meeting a window and missing it.
- 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 Kandla
Do you provide propeller polishing at Kandla Port?
Yes. Cleanship Marine works Kandla Port (INIXY) in Gujarat, India, covering the Kandla creek berths, oil jetties and outer anchorage. We hold an operating base at Kandla, so people and equipment are held locally rather than mobilised against a window.
Can propeller polishing be done while the vessel works cargo at Kandla?
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 Kandla and tell you honestly whether the window you have is enough.
Do you need a diving permit from Deendayal Port Authority?
Yes, and we obtain it. Diving permission from Deendayal Port Authority, 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 Kandla?
Visibility at Kandla 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 Kandla?
Product and chemical tankers, Bulk carriers, General cargo ships — the traffic at Kandla Port runs to pol and edible oils, fertiliser and raw materials, grain, 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 Kandla?
Cleanship keeps an operating base at Kandla, so response here is fast — the constraint is normally the approvals and the working window rather than getting divers and equipment to the port.
What does propeller polishing at Kandla cost?
It depends on the vessel's dimensions and wetted area, the fouling state found, the coating specification and the working window available at Kandla. 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 Kandla and you get a scoped price, usually the same working day.
