Cleanship Marine provides underwater hull cleaning at Dakar Port, Dakar, working the container and general cargo berths, bunkering 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.
Dakar is West Africa's northern gateway and a major bunkering and fishing port, working containers, phosphate and agricultural bulk for Senegal and the landlocked Sahel. Its shelter and its position on the Europe–South America routes make it a natural call for in-water work on this coast.
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 Dakar
Dakar sits on the sheltered side of the Cap-Vert peninsula, which puts it out of the worst of the Atlantic swell and makes it the most reliably workable port on this stretch of coast. Water is cooler here than in the Gulf of Guinea because of the Canary Current, so fouling is slower than at Conakry or Abidjan — an unusual thing to be able to say in West Africa. Bunkering traffic gives a steady anchorage population.

What we do at Dakar
- 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 Port Autonome de Dakar 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 Dakar
The Atlantic swell and the rains governs the calendar at Dakar 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 container and general cargo berths, bunkering anchorage, fishing port quays, and which of those a vessel ends up at changes the dive plan more than the season does. Teams mobilise via Dakar (DSS), 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 Dakar
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.
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 Dakar
- 1
Scope and vessel details
Tell us the vessel, her particulars, the coating specification and the window at Dakar. 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
Port Autonome de Dakar 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 Dakar
Divers, compressors, brush carts and cameras mobilise via Dakar (DSS). Where a vessel is also calling at Conakry, 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 Dakar
Do you provide underwater hull cleaning at Dakar Port?
Yes. Cleanship Marine works Dakar Port (SNDKR) in Dakar, Senegal, covering the container and general cargo berths, bunkering anchorage, fishing port quays. Teams mobilise via Dakar (DSS) with the full spread.
Can underwater hull cleaning be done while the vessel works cargo at Dakar?
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 Dakar and tell you honestly whether the window you have is enough.
Do you need a diving permit from Port Autonome de Dakar?
Yes, and we obtain it. Diving permission from Port Autonome de Dakar, 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 Dakar?
Visibility at Dakar 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 underwater hull cleaning on at Dakar?
Container ships, Handysize bulk carriers, Product tankers and bunker barges, Fishing fleet and reefer vessels — the traffic at Dakar Port runs to containers, phosphate, groundnuts and agricultural bulk, 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 Dakar?
Divers and equipment mobilise via Dakar (DSS). 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 Conakry or Monrovia, one mobilisation is often sized to cover both.
What does underwater hull cleaning at Dakar cost?
It depends on the vessel's dimensions and wetted area, the fouling state found, the coating specification and the working window available at Dakar. 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 Dakar and you get a scoped price, usually the same working day.
