Cleanship Marine runs full UWILD programmes — Underwater Inspection In Lieu of Drydocking — at Gambia River Terminals, Banjul, 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 tankers serving The Gambia are its fuel supply, and a tanker away for a dry dock is a gap in it. UWILD can keep an eligible tanker in service, but tanker eligibility is narrower than for most ships, especially for older vessels, so it is checked with class first. With the estuary water cloudy and tidal, the inspection itself is usually better planned at Dakar or at the outer anchorage beyond the bar than inside the river.

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 Gambia River

The inner anchorage off Banjul is 14 to 15 metres deep, a wide stretch of the estuary about a mile across and two miles long — far deeper than the port's own oil berth, which has only 5 to 6 metres. So the larger tankers bringing fuel to The Gambia either lie at anchor or moor at the conventional buoy mooring at Mandinari, about four nautical miles south of the commercial port, where they are held fore and aft between buoys. It is all tidal estuary water: the stream runs hard on the ebb and flood, and visibility is low.

Planning the window at Gambia River

The combination of Atlantic swell and rain governs the calendar at Gambia River Terminals, 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 in the estuary sets the method here: dives are timed to slack water at the anchorage, the team works by touch under surface supervision in low visibility, and nothing is done at the Mandinari buoys while a tanker is moored and discharging.

Work is taken at the inner anchorage off Banjul, Mandinari conventional buoy mooring and outer anchorage beyond the bar, 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 Gambia River

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.

Vessels at the Banjul anchorage are waiting, often for days, in warm, nutrient-rich estuary water — ideal conditions for growth. Tankers waiting for Mandinari or for lighterage collect fouling across the flat bottom, and the sea chests pick up both growth and river silt.

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 Gambia River

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

Do you provide UWILD at Gambia River Terminals?

Yes. Cleanship Marine works Gambia River Terminals (GMBJL) in Banjul, The Gambia, covering the inner anchorage off Banjul, Mandinari conventional buoy mooring and outer anchorage beyond the bar. Teams mobilise via Banjul (BJL) with the full spread.

Is UWILD possible for a tanker trading to the Gambia River?

It can be, but tanker eligibility needs to be checked with the class society first, especially for older tankers. If she qualifies, we usually plan the inspection at Dakar or the outer anchorage, where the water is clearer than inside the estuary.

Can UWILD be done while the vessel works cargo at Gambia River?

Not while a tanker is moored at Mandinari and discharging. Hull work is done at the inner anchorage at slack water — usually during the wait for a berth or for the buoys, which at Banjul is time the vessel is spending anyway. The vessel stays on hire throughout, and there is no diversion and no dry dock. We scope against the conditions at Gambia River 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 Gambia River?

Visibility at Gambia River Terminals is low — this is a tidal estuary carrying sediment down the Gambia River, and it is at its worst in the rainy season when the river is in flood, 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 UWILD on at Gambia River?

Product tankers, Vessels waiting for a Banjul berth, Lightering and bunker barges — the traffic at Gambia River Terminals runs to fuel and petroleum products, transhipment and lightering 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 Gambia River?

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 Banjul or Dakar, one mobilisation is often sized to cover both.

What does UWILD at Gambia River cost?

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