Cleanship Marine provides underwater hull cleaning at Galle Port, Southern Province, working the inner harbour berths and anchorage. Commercial dive teams remove slime, weed and shell growth from the vertical sides, flat bottom, bilge keels, sea chests and niche areas with the vessel afloat and on hire — no dry dock, no diversion, no off-hire.
Galle is Sri Lanka's southern harbour, working general cargo, a substantial fishing fleet and a growing yacht and leisure trade. Its clear water and small tonnage make it a practical place for survey and inspection work rather than large-area cleaning.
What it gets you
- Hydrodynamic smoothness restored before fouling reaches the calcareous stage that damages coating
- Fuel and emissions penalty from drag reduced without taking the vessel off hire
- Documented condition record for the technical file and the next docking specification
- Sea chests and inlets cleared, protecting cooling water flow
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.

What we do at Galle
- Pre-clean fouling survey to establish coverage, growth type and coating condition before any tool touches the hull
- Brush cart cleaning of the flat bottom and vertical sides, with brush hardness selected against your antifouling specification
- Hand cleaning of bilge keels, rudder, stern frame, thruster tunnels, anodes and the niches a cart cannot follow
- Sea chest gratings and inlet openings cleared of growth and debris to restore cooling water flow
- Diving permission cleared with Sri Lanka Ports Authority and the terminal before mobilisation
- Before-and-after video and stills, with a written report on coating condition and anode wastage
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 underwater hull cleaning attendance, wherever the vessel is. Anything outside it is quoted separately and flagged before mobilisation, never added afterwards.
- Fouling survey
- A pre-clean dive establishes fouling type, coverage and severity, and confirms coating condition so the correct tooling is selected.
- Flat bottom and vertical sides
- Brush cart cleaning of large areas, removing slime, weed and shell growth to restore surface smoothness.
- Niche areas
- Hand cleaning of bilge keels, bow thruster tunnels, rudder, stern frame, anodes and other niche areas where fouling concentrates.
- Sea chests and gratings
- Sea chest gratings and inlet openings cleared of growth and debris to restore cooling water flow.
- Documentation
- Underwater video and stills before and after, with a written report covering coating condition and anode wastage.
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 underwater hull cleaning 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 — Underwater Hull Cleaning at Galle
Do you provide underwater hull cleaning 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 underwater hull cleaning 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 underwater hull cleaning 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 underwater hull cleaning 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.
