Full thrust restored when you need it most

Cleanship Marine cleans and polishes bow and stern thrusters at Takoradi Port, Western Region. Divers clear the full tunnel bore, polish the blades and hub, and clear the gratings, restoring the manoeuvring thrust that quietly disappears while a vessel sits idle.
Thruster tunnels are the worst fouling trap on a hull — sheltered, still and almost never inspected. That matters more than usual at Takoradi, where Ghana's offshore support base and bulk export port keeps vessels stationary in warm water for extended periods and growth builds on tunnel walls, blades and gratings until manoeuvring performance is noticeably down at exactly the moment it is needed.
What it gets you
- Manoeuvring thrust restored ahead of a berthing or a pilotage that needs it
- Tunnel and grating flow cleared, not just the visible blade faces
- Seal, boss and anode condition documented while the divers are already down
- Reduced reliance on tug assistance where thrust had quietly degraded
Working conditions at Takoradi
Takoradi is a breakwater harbour with good shelter and it is the shore base for Ghana's offshore oil industry, so there is a resident support fleet here as well as transiting bulk tonnage. That resident fleet is the regular in-water customer: OSVs between charters sit in warm water and foul heavily. Atlantic swell governs the anchorage; the basin itself works year-round.

- Handysize and Supramax bulk carriers · Offshore support vessels · General cargo and reefer vessels · Feeder container ships
What we do at Takoradi
- Full tunnel bore cleaned end to end, both openings, including the areas behind the gratings
- Blade and hub polished, with seal and boss condition inspected and reported
- Tunnel gratings cleared of growth and debris so flow is restored, not just the visible face
- Anodes inside the tunnel checked and wastage recorded
- Diving permission cleared with Ghana Ports and Harbours Authority, with the thruster confirmed isolated and tagged out before the dive
- Video record of tunnel and blade condition before and after
Planning the window at Takoradi
The Atlantic swell and the rains governs the calendar at Takoradi Port, 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 breakwater berths, bulk loading quays, offshore support base and anchorage, and which of those a vessel ends up at changes the dive plan more than the season does. Teams mobilise via Takoradi (TKD) or 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 Takoradi
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 Takoradi than owners budget for.
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.
Standard scope of work
Included as standard on every thruster cleaning attendance, wherever the vessel is. Anything outside it is quoted separately and flagged before mobilisation, never added afterwards.
- Tunnel cleaning
- Fouling removed from the full length of the tunnel bore, including the areas behind gratings where growth is heaviest.
- Blade cleaning and polishing
- Propeller blades and hub cleaned and polished to restore surface finish and reduce cavitation-inducing roughness.
- Grating and guard clearance
- Gratings and rope guards cleared of growth, netting and debris that restrict flow or risk fouling the unit.
- Condition inspection
- Blade edges, seals and visible gearcase condition inspected and recorded, with any damage reported immediately.
How we deliver it at Takoradi
- 1
Scope and vessel details
Tell us the vessel, her particulars, the coating specification and the window at Takoradi. 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 Takoradi
Divers, compressors, brush carts and cameras mobilise via Takoradi (TKD) or 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 thruster 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 — Thruster Cleaning at Takoradi
Do you provide thruster cleaning at Takoradi Port?
Yes. Cleanship Marine works Takoradi Port (GHTKD) in Western Region, Ghana, covering the breakwater berths, bulk loading quays, offshore support base and anchorage. Teams mobilise via Takoradi (TKD) or Accra (ACC) with the full spread.
Can thruster cleaning be done while the vessel works cargo at Takoradi?
Yes, in most cases. The harbour is sheltered enough that divers work alongside while cargo operations continue, and neither holds the other up. The vessel stays on hire throughout, and there is no diversion and no dry dock. We scope against the conditions at Takoradi 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 Takoradi?
Visibility at Takoradi Port is moderate, and it drops further around active bulk handling and after heavy rain, and the Atlantic swell and the rains 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 thruster cleaning on at Takoradi?
Handysize and Supramax bulk carriers, Offshore support vessels, General cargo and reefer vessels, Feeder container ships — the traffic at Takoradi Port runs to manganese ore, bauxite and cocoa, 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 Takoradi?
Divers and equipment mobilise via Takoradi (TKD) or 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 Abidjan, one mobilisation is often sized to cover both.
What does thruster cleaning at Takoradi cost?
It depends on the vessel's dimensions and wetted area, the fouling state found, the coating specification and the working window available at Takoradi. 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 Takoradi and you get a scoped price, usually the same working day.
