Cleanship Marine delivers class-approved in-water surveys at Dakar Port, Dakar, with high-definition live video to a surface monitoring station, diver-to-surveyor communications and a full report package for the class file.
Classification societies accept in-water survey in place of drydocking for many vessels and inspection scopes, provided the work is done by an approved diving contractor to a defined procedure with the surveyor able to see the structure in real time. Shelter is on your side here — the vessel is stable and the dive is uninterrupted — but basin silt means the lighting and camera plan has to be agreed with the surveyor before the class attendance is booked, not improvised on the day.
What it gets you
- Survey requirement satisfied without opening a dry dock or taking the vessel off hire
- Surveyor sees the structure live rather than reviewing a recording after the fact
- Defects located precisely against hull reference marks, not described approximately
- A report package built for the class file, not a video dump
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
- Survey programme agreed in advance with the class society and the surveyor attending at Dakar
- Hull plating, welds, sea chests, rudder, propeller and stern gear inspected to the agreed scope
- Live high-definition video to the surface station with two-way diver-to-surveyor communications
- Hull markings and reference points confirmed so the surveyor can locate every feature precisely
- Diving permission and any environmental clearance cleared with Port Autonome de Dakar
- Full report package with video, stills and findings issued for the class file
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 in-water class survey attendance, wherever the vessel is. Anything outside it is quoted separately and flagged before mobilisation, never added afterwards.
- Hull structure inspection
- Shell plating, welds, bilge keels and openings inspected with continuous video and commentary, with cleaning of areas as needed for meaningful viewing.
- Rudder and steering gear
- Rudder plating, pintles, bearings and clearances inspected and, where required, measured.
- Propeller and stern arrangement
- Propeller, boss, rope guard and stern tube seal inspected for damage, erosion and leakage.
- Sea chests and openings
- Sea chests, gratings, valves and overboard discharges inspected and recorded.
- Anodes and coating
- Sacrificial anode wastage assessed and coating condition mapped for planning the next dry docking.
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 in-water class survey 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 — In-Water Survey at Dakar
Do you provide in-water class survey 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 in-water class survey 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 in-water class survey 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 in-water class survey 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.
