Cleanship Marine provides the full underwater scope at Gambia River Terminals (GMBJL), Banjul — 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.

This is the part of the Port of Banjul where the big ships wait and where the fuel comes in. The inner anchorage holds vessels waiting for a berth at Banjul and tankers too deep for the oil berth, and the Mandinari buoy mooring handles tanker discharge for the country's fuel supply. For most tankers calling The Gambia, the anchorage and Mandinari — not the quays — are where they spend their time.

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.

Where we work: Inner anchorage off Banjul · Mandinari conventional buoy mooring · Outer anchorage beyond the bar
Vessels we see here: Product tankers · Vessels waiting for a Banjul berth · Lightering and bunker barges

Hull Cleaning scopes at Gambia River

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

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.

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 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 — Gambia River Terminals

Does Cleanship provide hull cleaning at Gambia River Terminals?

Yes. We cover the full hull cleaning scope at Gambia River Terminals (GMBJL), Banjul — underwater hull cleaning, propeller polishing, thruster cleaning & polishing, in-water class survey and UWILD. Teams mobilise via Banjul (BJL).

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.

Who approves hull cleaning work at Gambia River?

Gambia Ports Authority issues the port-side approval at Gambia River Terminals, 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 Gambia River?

Product tankers, Vessels waiting for a Banjul berth, Lightering and bunker barges — Gambia River Terminals is the deep-water anchorage and tanker moorings of the Gambia River, handling fuel and petroleum products, transhipment and lightering cargo. 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 Gambia River?

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 Gambia River?

Yes. Banjul, Dakar and Conakry 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.
