Cleanship Marine runs full UWILD programmes — Underwater Inspection In Lieu of Drydocking — at Vale dos Cavaleiros Port, Fogo, from eligibility discussion through class liaison to the final report package.
UWILD lets a vessel satisfy a survey requirement that would otherwise mean a dry docking, at a fraction of the cost and with none of the off-hire. The requirements are exacting: the contractor must hold class approval, the vessel must be eligible, hull markings must let the surveyor locate features precisely, and the inspection has to be delivered live and documented. Survey work at an open anchorage lives and dies on the weather window, so class attendance is booked with a realistic standby allowance rather than a single optimistic date.
The vessels that serve Fogo are the island's lifeline, and taking one out of service for a docking outside the archipelago leaves a gap in the island's supply. UWILD can avoid that for an eligible vessel. Because of the shallow berth and exposed coast, the inspection itself is planned at anchor in a swell window here, or at Praia if that suits the timetable better — the goal is to keep the ferry on her route.
What it gets you
- Drydocking deferred and the survey credit earned in the water
- Class liaison handled end to end rather than left with the superintendent
- Eligibility confirmed before cost is committed, not discovered afterwards
- A documented inspection record that stands up to class review
Working conditions at Vale dos Cavaleiros
Vale dos Cavaleiros sits on the exposed west coast of Fogo, about three kilometres north of São Filipe, and the Atlantic swell that reaches this coast is the deciding factor for any in-water work. The port was rebuilt in 2013 with a heavy breakwater and two short piers — 70 and 95 metres long, both about 5 metres deep — which is enough for ferries and coasters but leaves little water under the keel. Larger coasters and any dive that needs room lie off the port at anchor.

Planning the window at Vale dos Cavaleiros
The trade-wind and swell season governs the calendar at Vale dos Cavaleiros Port, with the strongest trade winds from roughly December to May, and a short rainy season from August to October. The islands sit in open ocean, so a port's exposure depends on which side of its island it faces: the lee-side harbours stay calm while the trade wind blows, but long-period swell from North Atlantic storms reaches the north and west coasts in winter, and the late-summer tropical waves that pass through here can turn into storms. Work here is done with the vessel riding to her anchor, so the dive plan is built around sea state and swell rather than a berth slot, and the team stands by for a workable window rather than a scheduled one.
Work is taken at the two short piers behind the breakwater and anchorage off the port, and which of those a vessel ends up at changes the dive plan more than the season does. Teams mobilise via São Filipe (SFL) or Praia (RAI), 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 Vale dos Cavaleiros
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 ferries and coasters serving Fogo are rarely idle for long — they run the island's supply on a tight schedule — so the fouling we find is steady, even growth from constant short trips in warm water rather than the heavy build-up of a long wait. The niches are the exception: thruster tunnels, sea chests and the stern gear collect growth that the hull flow never clears.
Standard scope of work
Included as standard on every UWILD attendance, wherever the vessel is. Anything outside it is quoted separately and flagged before mobilisation, never added afterwards.
- Eligibility and planning
- Vessel eligibility, survey scope and the society's specific requirements are established and agreed before mobilisation.
- Hull preparation
- Reference markings and cleaning of inspection areas so structure and features can be located and viewed unambiguously.
- Systematic inspection
- Shell plating, welds, rudder, propeller, sea chests, openings, anodes and appendages inspected to the agreed programme.
- Measurement and NDT
- Clearance measurement and underwater NDT carried out where the survey scope requires it.
- Documentation
- Video, stills, measurements and findings compiled into a report package suitable for submission to the classification society.
How we deliver it at Vale dos Cavaleiros
- 1
Scope and vessel details
Tell us the vessel, her particulars, the coating specification and the window at Vale dos Cavaleiros. 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
ENAPOR – Portos de Cabo Verde 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 Vale dos Cavaleiros
Divers, compressors, brush carts and cameras mobilise via São Filipe (SFL) or Praia (RAI). Where a vessel is also calling at Furna, 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 UWILD 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 — UWILD Inspection at Vale dos Cavaleiros
Do you provide UWILD at Vale dos Cavaleiros Port?
Yes. Cleanship Marine works Vale dos Cavaleiros Port in Fogo, Cape Verde, covering the two short piers behind the breakwater and anchorage off the port. Teams mobilise via São Filipe (SFL) or Praia (RAI) with the full spread.
Where would UWILD be done for a ferry serving Fogo?
Either at anchor off Vale dos Cavaleiros in a calm window, or at Praia, whichever fits the ferry's timetable and the surveyor's attendance better. We check eligibility with class first, then plan the location around keeping the ferry in service.
Can UWILD be done while the vessel works cargo at Vale dos Cavaleiros?
Not usually at the berth. The piers are short and shallow and are needed for the next ferry or coaster, so hull work is done at anchor off the port — or, for a ferry, during a lay-over — in a window the swell allows. The vessel stays on hire throughout, and there is no diversion and no dry dock. We scope against the conditions at Vale dos Cavaleiros and tell you honestly whether the window you have is enough.
Do you need a diving permit from ENAPOR – Portos de Cabo Verde?
Yes, and we obtain it. Diving permission from ENAPOR – Portos de Cabo Verde, 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 Vale dos Cavaleiros?
Visibility at Vale dos Cavaleiros Port is usually good — it is open ocean water — but swell stirs up the dark volcanic sand in the shallows near the piers, and the trade-wind and swell season 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 UWILD on at Vale dos Cavaleiros?
Inter-island ferries and General cargo coasters — the traffic at Vale dos Cavaleiros Port runs to general cargo, construction materials, food and supplies, 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 Vale dos Cavaleiros?
Divers and equipment mobilise via São Filipe (SFL) or Praia (RAI). 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 Furna or Praia, one mobilisation is often sized to cover both.
What does UWILD at Vale dos Cavaleiros cost?
It depends on the vessel's dimensions and wetted area, the fouling state found, the coating specification and the working window available at Vale dos Cavaleiros. 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 Vale dos Cavaleiros and you get a scoped price, usually the same working day.
