Cleanship Marine provides the full underwater scope at Colombo Port (LKCMB), Western Province — hull cleaning, propeller super polishing, bow and stern thruster work, class-approved in-water survey and UWILD. Every scope is carried out with the vessel afloat and on hire, at the berth or at the anchorage.

Colombo is South Asia's largest transhipment hub and one of the busiest bunkering ports on the Europe–Asia route, handling main-line container tonnage that would not otherwise call in the region. Cleanship keeps an office here, and the port sits directly on the rotation for vessels working the Indian coverage.

Working conditions at Colombo

Colombo works behind long breakwaters and is well sheltered, so alongside work runs year-round and the south-west monsoon from May to September governs the anchorage rather than the berth. The bunkering anchorage carries a standing population of vessels waiting for fuel or orders, which is where most in-water work here actually happens. Harbour water is warm and turbid with moderate visibility; fouling returns fast.

Where we work: Container terminal berths · Bunkering anchorage · General cargo quays
Vessels we see here: Main-line and feeder container ships · Bunker tankers and barges · General cargo ships · Cruise ships

Hull Cleaning scopes at Colombo

5 scopes, one team and one mobilisation. Most vessels calling here take more than one on the same attendance.

Planning the window at Colombo

The two monsoons governs the calendar at Colombo 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. Because the harbour is sheltered, work here normally runs alongside or at a protected anchorage and can proceed in parallel with cargo operations rather than competing with them for the berth window.

Work is taken at the container terminal berths, bunkering anchorage and general cargo quays, and which of those a vessel ends up at changes the dive plan more than the season does. Cleanship holds an operating base at Colombo, 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 Colombo

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.

Shelter is a mixed blessing for a hull. The same calm that makes the port easy to work in is still water, and still water grows fouling faster than an exposed berth does.

How we deliver it at Colombo

1
Scope and vessel details
Tell us the vessel, her particulars, the coating specification and the window at Colombo. 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 runs a statutory permit process here, so the lead time is real and the application goes in early rather than on arrival. 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 Colombo
Cleanship holds an operating base at Colombo, 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 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 — Colombo Port

Does Cleanship provide hull cleaning at Colombo Port?

Yes. We cover the full hull cleaning scope at Colombo Port (LKCMB), Western Province — underwater hull cleaning, propeller polishing, thruster cleaning & polishing, in-water class survey and UWILD. Cleanship holds an operating base at Colombo.

What is underwater visibility like at Colombo?

Visibility at Colombo Port is moderate, and it drops further around active bulk handling and after heavy rain, 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.

Who approves hull cleaning work at Colombo?

Sri Lanka Ports Authority issues the port-side approval at Colombo Port, with terminal approval on top where the berth requires it. We arrange both, along with any environmental clearance for in-water cleaning, so it does not fall to the agent or the master.

Which vessels call at Colombo?

Main-line and feeder container ships, Bunker tankers and barges, General cargo ships, Cruise ships — Colombo Port is South Asia's largest transhipment and bunkering hub, handling containers and transhipment, bunkers, general cargo, cement and dry bulk, tea and agricultural cargo. Wetted area, coating specification and how long the vessel has been sitting are what size a hull job, so the same berth can produce very different attendances.

Can this be done without taking the vessel off hire at Colombo?

Yes — that is the point of it. Every scope listed here is carried out with the vessel afloat and working, at the berth, at the anchorage or on the passage out. Divers work with the vessel afloat at the berth or the anchorage, so there is no dry dock, no diversion and no off-hire.

Do you cover other ports near Colombo?

Yes. Galle, Trincomalee and Puttalam all sit within the same operating range for hull cleaning, and a single mobilisation is often sized to cover more than one vessel on the same trip. We work 65 ports on the coverage list for this line.
