Cleanship Marine carries out underwater propeller super polishing at Galle Port, Southern Province. 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 Galle: it runs at high relative velocity, so roughness there costs disproportionately more than the same roughness spread over the hull. For the coasters and small general cargo ships, fishing fleet and support craft, yachts and leisure vessels 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 Galle
Galle is a natural harbour on the south coast with markedly clearer water than Colombo, which makes it one of the better ports in the region for documented in-water inspection. The south-west monsoon from May to September hits this coast directly and closes most of the season; the north-east monsoon leaves it workable. Traffic is small tonnage, so jobs here are short but frequent.

- Coasters and small general cargo ships · Fishing fleet and support craft · Yachts and leisure vessels
What we do at Galle
- 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 Sri Lanka Ports 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 Galle
The two monsoons governs the calendar at Galle Port, the south-west from May to September and the north-east from December to February. Which one matters depends on which coast the port is on — the south-west monsoon closes the western and southern anchorages while the east coast stays workable, and the north-east monsoon reverses it. Sri Lanka is the one market on the coverage list where there is almost always a workable coast. 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 inner harbour berths and anchorage, and which of those a vessel ends up at changes the dive plan more than the season does. Teams mobilise via Colombo (CMB), 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 Galle
The working fleet here spends most of its life at low speed in warm water, so growth is heavy, mixed and reaches the hard calcareous stage sooner than on deep-sea tonnage. Left too long it starts damaging the coating rather than just slowing the vessel.
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 Galle
- 1
Scope and vessel details
Tell us the vessel, her particulars, the coating specification and the window at Galle. 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
Sri Lanka Ports Authority approves the work alongside the local harbour master, and at a state port that conversation is quicker but less formal — it is worth having in writing. Diving permission, terminal approval and any environmental clearance for in-water work are handled by us, not left with the agent to chase.
- 3
Mobilisation to Galle
Divers, compressors, brush carts and cameras mobilise via Colombo (CMB). Where a vessel is also calling at Colombo, 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 Galle
Do you provide propeller polishing at Galle Port?
Yes. Cleanship Marine works Galle Port (LKGAL) in Southern Province, Sri Lanka, covering the inner harbour berths and anchorage. Teams mobilise via Colombo (CMB) with the full spread.
Can propeller polishing be done while the vessel works cargo at Galle?
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 Galle and tell you honestly whether the window you have is enough.
Do you need a diving permit from Sri Lanka Ports Authority?
Yes, and we obtain it. Diving permission from Sri Lanka Ports 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 Galle?
Visibility at Galle Port is good by regional standards and usually adequate for video work, and the two monsoons 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 Galle?
Coasters and small general cargo ships, Fishing fleet and support craft, Yachts and leisure vessels — the traffic at Galle Port runs to general cargo, fishing catch, cement and dry bulk, 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 Galle?
Divers and equipment mobilise via Colombo (CMB). 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 Colombo or Trincomalee, one mobilisation is often sized to cover both.
What does propeller polishing at Galle cost?
It depends on the vessel's dimensions and wetted area, the fouling state found, the coating specification and the working window available at Galle. 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 Galle and you get a scoped price, usually the same working day.
