Cleanship Marine provides the full underwater scope at Tarrafal Port (CVTAR), São Nicolau — hull cleaning, propeller super polishing, bow and stern thruster work, class-approved in-water survey and UWILD. Every scope is carried out with the vessel afloat and on hire, at the berth or at the anchorage.

Tarrafal is the main port of São Nicolau and a fishing town above all: the Sucla tuna cannery here is one of the island's largest employers, processing tuna caught in the surrounding waters. Ferries and coasters connect the island to Mindelo and Praia, and the rest of the traffic is the fishing fleet that supplies the cannery.

Working conditions at Tarrafal

Tarrafal is on the south-west coast of São Nicolau, in the lee of the island's mountains, and the sea bed drops away quickly offshore, so there is deep, clear ocean water close to the port. The trade wind is broken by the island but can come down off the high ground in gusts. The port is small and its quay is shared by ferries, coasters and the fishing fleet, so in-water work is fitted around them or done at anchor off the town.

Where we work: Port quay · Fishing boat moorings · Anchorage off Tarrafal
Vessels we see here: Tuna fishing vessels · Inter-island ferries · General cargo coasters

Hull Cleaning scopes at Tarrafal

5 scopes, one team and one mobilisation. Most vessels calling here take more than one on the same attendance.

Planning the window at Tarrafal

The trade-wind and swell season governs the calendar at Tarrafal 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. Water clarity here is good by regional standards, so the operation can be properly documented on video as it happens — an advantage that turns a cleaning job into usable condition evidence at no extra mobilisation cost.

Work is taken at the port quay, fishing boat moorings and anchorage off Tarrafal, and which of those a vessel ends up at changes the dive plan more than the season does. Teams mobilise via São Nicolau (SNE) or São Vicente (VXE), 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 Tarrafal

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.

Clearer water means the fouling state can be assessed properly before any tooling is selected, and the assessment can be shown to you rather than described.

How we deliver it at Tarrafal

1
Scope and vessel details
Tell us the vessel, her particulars, the coating specification and the window at Tarrafal. 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 Tarrafal
Divers, compressors, brush carts and cameras mobilise via São Nicolau (SNE) or São Vicente (VXE). Where a vessel is also calling at Mindelo, 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 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 — Tarrafal Port

Does Cleanship provide hull cleaning at Tarrafal Port?

Yes. We cover the full hull cleaning scope at Tarrafal Port (CVTAR), São Nicolau — underwater hull cleaning, propeller polishing, thruster cleaning & polishing, in-water class survey and UWILD. Teams mobilise via São Nicolau (SNE) or São Vicente (VXE).

What is underwater visibility like at Tarrafal?

Visibility at Tarrafal Port is very good, with deep, clear ocean water close to the port and no river runoff, 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.

Who approves hull cleaning work at Tarrafal?

ENAPOR – Portos de Cabo Verde issues the port-side approval at Tarrafal Port, with terminal approval on top where the berth requires it. We arrange both, along with any environmental clearance for in-water cleaning, so it does not fall to the agent or the master.

Which vessels call at Tarrafal?

Tuna fishing vessels, Inter-island ferries and General cargo coasters — Tarrafal Port is São Nicolau's tuna port with deep clear water close inshore, handling fishing catch and canned tuna, general cargo, food and supplies. Wetted area, coating specification and how long the vessel has been sitting are what size a hull job, so the same berth can produce very different attendances.

Can this be done without taking the vessel off hire at Tarrafal?

Yes — that is the point of it. Every scope listed here is carried out with the vessel afloat and working, at the berth, at the anchorage or on the passage out. Divers work with the vessel afloat at the berth or the anchorage, so there is no dry dock, no diversion and no off-hire.

Do you cover other ports near Tarrafal?

Yes. Mindelo, Palmeira and Praia all sit within the same operating range for hull cleaning, and a single mobilisation is often sized to cover more than one vessel on the same trip. We work 80 ports on the coverage list for this line.
