Cleanship Marine delivers class-approved in-water surveys at Conakry Port, Conakry, 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. 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.
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 Conakry
Conakry works a congested anchorage as much as a berth, and vessels routinely wait days for a slot — which is why so much in-water work here is done at anchor. The Atlantic swell running onto this coast is long-period ground swell rather than wind sea, so it reaches the anchorage on days that look calm from the bridge, and it is the main reason a booked window is lost. Water is warm year-round and visibility is moderate, dropping sharply around active bauxite transfer.

Planning the window at Conakry
The Atlantic swell and the rains governs the calendar at Conakry 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. Work here is done with the vessel riding to her anchor, so the dive plan is built around sea state and swell rather than a berth slot, and the team stands by for a workable window rather than a scheduled one.
Work is taken at the bauxite loading anchorage, container and general cargo berths, outer anchorage, and which of those a vessel ends up at changes the dive plan more than the season does. Cleanship holds an operating base at Conakry, so we can hold a team ready against a shifting ETA rather than committing travel to a date that may move.
What we typically find at Conakry
Dry bulk handling here puts cargo dust into the water around the berths and anchorage. It settles on horizontal surfaces and packs into sea chest gratings and inlet openings, so inlet and grating clearance is routinely a larger part of the job at Conakry than owners budget for.
Vessels here sit at anchor for long periods, and a stationary hull in warm water is the ideal fouling substrate. The heaviest growth we lift at this port is almost always off a vessel that has been waiting rather than working.
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 Conakry
- 1
Scope and vessel details
Tell us the vessel, her particulars, the coating specification and the window at Conakry. 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
Port Autonome de Conakry 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.

Mobilisation to Conakry
Cleanship holds an operating base at Conakry, so divers, compressors, brush carts and cameras are on the ground rather than in transit. That is the difference between meeting a window and missing it.
- 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 Conakry
Do you provide in-water class survey at Conakry Port?
Yes. Cleanship Marine works Conakry Port (GNCKY) in Conakry, Guinea, covering the bauxite loading anchorage, container and general cargo berths, outer anchorage. We hold an operating base at Conakry, so people and equipment are held locally rather than mobilised against a window.
Can in-water class survey be done while the vessel works cargo at Conakry?
Yes — it is the norm here, because the work is done at anchor rather than at a berth. Barge operations carry on around the dive, with the working side agreed with the master beforehand. The vessel stays on hire throughout, and there is no diversion and no dry dock. We scope against the conditions at Conakry and tell you honestly whether the window you have is enough.
Do you need a diving permit from Port Autonome de Conakry?
Yes, and we obtain it. Diving permission from Port Autonome de Conakry, 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 Conakry?
Visibility at Conakry Port is generally workable outside the monsoon, though cargo dust from lighterage reduces it sharply near an active transfer, and the Atlantic swell and the rains 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 Conakry?
Capesize and Panamax bulk carriers, Feeder container ships, General cargo ships, Transhipment barges and tugs — the traffic at Conakry Port runs to bauxite and alumina, iron ore, containers, 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 Conakry?
Cleanship keeps an operating base at Conakry, so response here is fast — the constraint is normally the approvals and the working window rather than getting divers and equipment to the port.
What does in-water class survey at Conakry cost?
It depends on the vessel's dimensions and wetted area, the fouling state found, the coating specification and the working window available at Conakry. 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 Conakry and you get a scoped price, usually the same working day.
