Cleanship Marine provides underwater hull cleaning at Puttalam Port, North Western Province, working the cement jetty and lagoon 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.
Puttalam is Sri Lanka's cement and limestone port, working clinker, coal and salt through a jetty and a lightering anchorage on the north-west coast. Traffic is smaller bulk tonnage and barges on short regional voyages.
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 Puttalam
Puttalam is a shallow lagoon port serving the cement industry, so depth restricts what can come alongside and larger tonnage is lightened at anchor. Lagoon water is warm, brackish and silty with low visibility, and cement and limestone dust in the water column reduces it further around active loading. The south-west monsoon is the limiting season.

What we do at Puttalam
- 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 Puttalam
The two monsoons governs the calendar at Puttalam 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. 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 cement jetty, lagoon anchorage and lightering position, 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 Puttalam
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 Puttalam 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 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 Puttalam
- 1
Scope and vessel details
Tell us the vessel, her particulars, the coating specification and the window at Puttalam. 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 Puttalam
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 Puttalam
Do you provide underwater hull cleaning at Puttalam Port?
Yes. Cleanship Marine works Puttalam Port (LKPTL) in North Western Province, Sri Lanka, covering the cement jetty, lagoon anchorage and lightering position. Teams mobilise via Colombo (CMB) with the full spread.
Can underwater hull cleaning be done while the vessel works cargo at Puttalam?
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 Puttalam 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 Puttalam?
Visibility at Puttalam Port is habitually very low, and often close to nil at the turn, 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 Puttalam?
Handysize bulk carriers, Barges and coastal craft — the traffic at Puttalam Port runs to cement and clinker, limestone, coal, 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 Puttalam?
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 Puttalam cost?
It depends on the vessel's dimensions and wetted area, the fouling state found, the coating specification and the working window available at Puttalam. 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 Puttalam and you get a scoped price, usually the same working day.
