Cleanship Marine provides underwater hull cleaning at Jamestown Fishing Port, Accra, Greater Accra, working the Jamestown harbour basin and berths inside the breakwater. 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.
Accra's cargo port is Tema, 25 kilometres along the coast; Jamestown is the capital's fishing port. The Jamestown Fishing Port Complex, built by CRCC with a Chinese government grant and inaugurated in September 2024, has a breakwater, berths, a fish market, a 60-tonne-a-day ice plant, a 200-tonne cold store and a repair workshop, and serves one of the oldest fishing communities on the Ghanaian coast.
Most boats working out of Jamestown are inshore and semi-industrial fishing vessels rather than cargo ships, and for them hull fouling is a daily fuel cost on every run to the fishing grounds. The new sheltered basin means these boats can now be cleaned in the water alongside, between trips, instead of waiting to be hauled out. For bigger ships calling Accra — container, bulk and tanker traffic — the port is Tema, not Jamestown.
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 Accra
Jamestown Fishing Port was built with a new breakwater, dredged basin, berths and navigation aids, turning what had been an exposed beach landing below the old Jamestown lighthouse into a sheltered harbour. Inside the breakwater the water is calm enough to work in most conditions; outside it, the Atlantic swell runs onto the Accra shoreline year-round. The basin is shallow by commercial standards, built for fishing craft rather than cargo ships.

What we do at Accra
- 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 Ghana Ports and Harbours 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 Accra
The combination of Atlantic swell and rain governs the calendar at Jamestown Fishing Port, Accra, with the heaviest rain from May to October and swell running year-round. The swell here is long-period Atlantic ground swell rather than wind-driven sea, so it reaches the anchorages on days that look calm from the bridge and it is the single biggest cause of a lost in-water window on this 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 Jamestown harbour basin, berths inside the breakwater and the repair workshop slipway area, and which of those a vessel ends up at changes the dive plan more than the season does. Teams mobilise via Accra (ACC), 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 Accra
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.
The vessels at Jamestown are inshore and semi-industrial fishing boats that spend long days slow or stationary on the grounds and then lie alongside between trips, so growth is heavy and mixed, and rope and netting around the propeller are as common as the fouling.
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 Accra
- 1
Scope and vessel details
Tell us the vessel, her particulars, the coating specification and the window at Accra. 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
Ghana Ports and Harbours 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 Accra
Divers, compressors, brush carts and cameras mobilise via Accra (ACC). Where a vessel is also calling at Tema, 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 Accra
Do you provide underwater hull cleaning at Jamestown Fishing Port, Accra?
Yes. Cleanship Marine works Jamestown Fishing Port, Accra in Greater Accra, Ghana, covering the Jamestown harbour basin, berths inside the breakwater and the repair workshop slipway area. Teams mobilise via Accra (ACC) with the full spread.
Can a fishing boat be hull-cleaned in the water at Jamestown instead of being hauled out?
Yes. Since the new breakwater and basin were built, fishing vessels can be cleaned alongside in sheltered water between trips. It is quicker and cheaper than hauling out and costs no fishing time. Larger ships calling Accra use Tema, which has its own page.
Can underwater hull cleaning be done while the vessel works cargo at Accra?
Between fishing trips, alongside in the sheltered basin. The harbour is a working fishing port, so the job is planned around landing times and berth space. The vessel stays on hire throughout, and there is no diversion and no dry dock. We scope against the conditions at Accra and tell you honestly whether the window you have is enough.
Do you need a diving permit from Ghana Ports and Harbours Authority?
Yes, and we obtain it. Diving permission from Ghana Ports and Harbours 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 Accra?
Visibility at Jamestown Fishing Port, Accra is moderate inside the new breakwater, reduced by run-off from the city after heavy rain and by stirred-up sediment in the shallow basin, and the combination of Atlantic swell and rain 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 Accra?
Inshore fishing vessels, Semi-industrial fishing boats and Motorised fishing canoes — the traffic at Jamestown Fishing Port, Accra runs to fishing catch, 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 Accra?
Divers and equipment mobilise via Accra (ACC). 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 Tema or Elmina, one mobilisation is often sized to cover both.
What does underwater hull cleaning at Accra cost?
It depends on the vessel's dimensions and wetted area, the fouling state found, the coating specification and the working window available at Accra. 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 Accra and you get a scoped price, usually the same working day.
