Cleanship Marine provides the full underwater scope at Trincomalee Port (LKTRR), Eastern 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.

Trincomalee is Sri Lanka's deep-water eastern harbour, working cement, grain and a large oil tank farm, with far more natural capacity than its current traffic uses. Its shelter and clarity make it the best place in the region to do work that needs time and visibility — and its counter-seasonal monsoon means it is workable when Colombo is not.

Working conditions at Trincomalee

Trincomalee is one of the largest natural deep-water harbours in the world and it is exceptionally sheltered — a vessel inside is out of the weather in a way no other port on this coverage list matches. Water is clear by regional standards and the harbour is deep enough to work large tonnage at anchor comfortably. The north-east monsoon from December to February is the limiting season here, which is the opposite of Colombo.

Where we work: Inner harbour berths · Oil terminal jetty · Deep anchorage

Hull Cleaning scopes at Trincomalee

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

Planning the window at Trincomalee

The two monsoons governs the calendar at Trincomalee 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, oil terminal jetty and deep anchorage, and which of those a vessel ends up at changes the dive plan more than the season does. Teams mobilise via Trincomalee or 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 Trincomalee

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 Trincomalee than owners budget for.

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.

How we deliver it at Trincomalee

1
Scope and vessel details
Tell us the vessel, her particulars, the coating specification and the window at Trincomalee. 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 Trincomalee
Divers, compressors, brush carts and cameras mobilise via Trincomalee or 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 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 — Trincomalee Port

Does Cleanship provide hull cleaning at Trincomalee Port?

Yes. We cover the full hull cleaning scope at Trincomalee Port (LKTRR), Eastern Province — underwater hull cleaning, propeller polishing, thruster cleaning & polishing, in-water class survey and UWILD. Teams mobilise via Trincomalee or Colombo (CMB).

What is underwater visibility like at Trincomalee?

Visibility at Trincomalee 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.

Who approves hull cleaning work at Trincomalee?

Sri Lanka Ports Authority issues the port-side approval at Trincomalee 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 Trincomalee?

Handysize bulk carriers, Product tankers and General cargo ships — Trincomalee Port is one of the world's largest natural deep-water harbours, handling cement and clinker, grain and agricultural bulk, POL and fuel storage, general 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 Trincomalee?

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 Trincomalee?

Yes. Colombo, Galle 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.
