Cleanship Marine delivers class-approved in-water surveys at Palmeira Port, Sal, 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. This is one of the better ports on the coverage list for in-water survey work: clarity supports the wide shots and the close detail a surveyor needs, and the record that comes out of it stands up in the class file.
For a class surveyor, visibility is everything, and Palmeira has more of it than almost any port a vessel is likely to call at in this part of the Atlantic. Sal has no rivers and very little rain, so there is no runoff and no silt to cloud the water. That makes it possible to record wide shots of the hull as well as close detail — the kind of evidence a surveyor can sign off with confidence rather than qualify.
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 Palmeira
Palmeira is on the west side of Sal, in the lee of an island that is flat, dry and swept by the north-east trade wind for most of the year. The island takes the wind; the bay behind it is calm. With almost no rainfall and no rivers, nothing clouds the water, and visibility here is among the best on the whole coverage list. The main constraint is the size of the port — a small pier that the fuel tankers, coasters and ferries share — so in-water work is planned around the berth schedule or taken at anchor in the bay.

Planning the window at Palmeira
The trade-wind and swell season governs the calendar at Palmeira 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 commercial pier, fuel discharge berth and anchorage in Palmeira bay, and which of those a vessel ends up at changes the dive plan more than the season does. Teams mobilise via Sal (SID), 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 Palmeira
Container tonnage on a fixed rotation shows the familiar pattern: light slime over most of the vertical sides, with the real accumulation in the flat bottom, the bilge keels and the niches where flow is slowest. Those are the areas that cost fuel and the ones a quick clean tends to skip.
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.
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 Palmeira
- 1
Scope and vessel details
Tell us the vessel, her particulars, the coating specification and the window at Palmeira. 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 Palmeira
Divers, compressors, brush carts and cameras mobilise via Sal (SID). Where a vessel is also calling at Sal Rei, 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 Palmeira
Do you provide in-water class survey at Palmeira Port?
Yes. Cleanship Marine works Palmeira Port (CVPAL) in Sal, Cape Verde, covering the commercial pier, fuel discharge berth and anchorage in Palmeira bay. Teams mobilise via Sal (SID) with the full spread.
What are survey conditions like at Palmeira?
Very good. Sal is dry and has no rivers, so the water in the bay is clear and calm, which supports both wide shots and close inspection. It is one of the best places on the Cape Verde coast for an in-water class survey.
Can in-water class survey be done while the vessel works cargo at Palmeira?
Yes. Conditions here are good enough that the dive runs alongside cargo operations without either holding the other up, and the work is documented on video as it goes. The vessel stays on hire throughout, and there is no diversion and no dry dock. We scope against the conditions at Palmeira 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 Palmeira?
Visibility at Palmeira Port is excellent: Sal has no rivers and almost no rain, so nothing clouds the water in the bay, 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 in-water class survey on at Palmeira?
Product tankers delivering fuel, Container and RoRo coasters, Inter-island ferries, Fishing vessels — the traffic at Palmeira Port runs to fuel imports, containers and general cargo, 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 Palmeira?
Divers and equipment mobilise via Sal (SID). 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 Sal Rei or Mindelo, one mobilisation is often sized to cover both.
What does in-water class survey at Palmeira cost?
It depends on the vessel's dimensions and wetted area, the fouling state found, the coating specification and the working window available at Palmeira. 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 Palmeira and you get a scoped price, usually the same working day.
