Cleanship Marine delivers class-approved in-water surveys at Banjul Port, Banjul, 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. Low visibility and short slack windows make this a demanding survey port. Scope, lighting and the surveyor's acceptance criteria are agreed up front, and where the conditions will not support the scope we say so before the attendance is booked.

The estuary water at Banjul is too cloudy for the wide shots a surveyor normally relies on, and slack-water windows are short. An in-water class survey here is possible, but only with close-quarters lighting, agreed acceptance criteria and a survey plan split across several tidal windows. Where a vessel's schedule allows, a survey at Dakar — a day's steaming north, in clearer Canary Current water — may give class a better picture, and we will say so up front.

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 Banjul

Banjul sits at the mouth of the Gambia River, and the water at its berths is estuary water: tidal, fast-flowing on the ebb and flood, and carrying sediment down from a river that drains a large part of West Africa. A sand bar in the entrance channel limits vessels to about a 9-metre draft, and the deepest-drafted ships time their passage to the flood tide. For in-water work that means two things — dives are timed to slack water, and visibility at the berths is low enough that divers work by touch under surface supervision.

Where we work: Banjul Wharf · New Banjul Jetty and container berths · Fisheries jetty · Banjul–Barra ferry terminal
Vessels we see here: Feeder container ships · General cargo ships · Banjul–Barra ferries · Fishing vessels · Small cruise ships

Planning the window at Banjul

The combination of Atlantic swell and rain governs the calendar at Banjul 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. The tidal stream and the silt load govern the method here: the working window is slack water, not the working day, and the operation is planned by feel and surface supervision with video kept as the record rather than as the diver's means of navigation.

Work is taken at the Banjul Wharf, New Banjul Jetty and container berths, fisheries jetty, Banjul–Barra ferry terminal, and which of those a vessel ends up at changes the dive plan more than the season does. Teams mobilise via Banjul (BJL), 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 Banjul

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.

Silt settles over the growth on the flat bottom and in the niches, which masks the true fouling state until the divers are actually on it. That is why the pre-clean survey here is a real step rather than a formality.

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 Banjul

1
Scope and vessel details
Tell us the vessel, her particulars, the coating specification and the window at Banjul. 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
Gambia Ports Authority 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 Banjul
Divers, compressors, brush carts and cameras mobilise via Banjul (BJL). Where a vessel is also calling at Gambia River, 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 Banjul

Do you provide in-water class survey at Banjul Port?

Yes. Cleanship Marine works Banjul Port (GMBJL) in Banjul, The Gambia, covering the Banjul Wharf, New Banjul Jetty and container berths, fisheries jetty, Banjul–Barra ferry terminal. Teams mobilise via Banjul (BJL) with the full spread.

Is Banjul a good place for an in-water class survey?

It is possible, but the estuary water is cloudy and slack-water windows are short, so the survey needs close-quarters lighting and several tidal windows. If the vessel's route allows, Dakar has much clearer water and may be the better choice. We advise honestly before the surveyor is booked.

Can in-water class survey be done while the vessel works cargo at Banjul?

Usually yes, but the tide sets the schedule rather than the cargo plan. The practical question is how many slack windows fall inside the vessel's stay, not what the holds are doing. The vessel stays on hire throughout, and there is no diversion and no dry dock. We scope against the conditions at Banjul and tell you honestly whether the window you have is enough.

Do you need a diving permit from Gambia Ports Authority?

Yes, and we obtain it. Diving permission from Gambia Ports Authority, 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 Banjul?

Visibility at Banjul Port is habitually very low, and often close to nil at the turn, and the combination of Atlantic swell and rain 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 Banjul?

Feeder container ships, General cargo ships, Banjul–Barra ferries, Fishing vessels and Small cruise ships — the traffic at Banjul Port runs to containers, rice, sugar and flour, cement 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 Banjul?

Divers and equipment mobilise via Banjul (BJL). 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 Gambia River or Dakar, one mobilisation is often sized to cover both.

What does in-water class survey at Banjul cost?

It depends on the vessel's dimensions and wetted area, the fouling state found, the coating specification and the working window available at Banjul. 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 Banjul and you get a scoped price, usually the same working day.
