Cleanship Marine delivers class-approved in-water surveys at Espoir Marine Terminal, Block CI-26, 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.
An FPSO that stays on station for years has to have its hull and moorings surveyed where it is, because it cannot go to a dry dock without stopping production. That makes in-water class survey work at Espoir a routine requirement, not an alternative. The survey programme — hull plating, sea chests, mooring connections and appendages — is agreed with the class society and the operator in advance and fitted around production and offloading.
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 Espoir
Espoir lies in open sea about 10 nautical miles south of Jacqueville and 32 nautical miles south-west of Abidjan, so everything here — the FPSO, the shuttle tankers and the support vessels — works in the full Atlantic swell with no shelter. The field has a wellhead platform feeding the FPSO, and all diving is done under the operator's field permit system, planned around production, offloading and the weather rather than a berth.

Planning the window at Espoir
The combination of Atlantic swell and rain governs the calendar at Espoir Marine Terminal, 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. There is no anchor and no berth here: the FPSO is held on station by her own moorings, and shuttle tankers and support vessels work around her, so the dive plan is built around the field's production and offloading programme and the swell, under the operator's permit system.
Work is taken at the FPSO Espoir Ivoirien on station, shuttle tanker offloading area and field support vessel moorings, and which of those a vessel ends up at changes the dive plan more than the season does. Teams mobilise via Abidjan (ABJ), 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 Espoir
Liquid and gas tonnage here spends long stretches at the terminal or waiting for a slot, so growth tends to be even and well established across the hull rather than patchy — heavier than the trading pattern suggests, and further along than a speed report alone would indicate.
An FPSO that has been on station for years has never had its hull cleaned by a dock, so growth builds in layers, and it matters most at the sea chests, water intakes and caissons, where fouling cuts the cooling and process water flow the plant depends on. Shuttle tankers and support vessels show the more familiar pattern of growth from long periods of slow steaming and waiting.
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 Espoir
- 1
Scope and vessel details
Tell us the vessel, her particulars, the coating specification and the window at Espoir. 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
Access at Espoir Marine Terminal is the terminal operator's decision as much as CNR International's, so both are in the approval chain from the start — a berth-side refusal discovered at the gangway costs the whole attendance. 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 Espoir
Divers, compressors, brush carts and cameras mobilise via Abidjan (ABJ). Where a vessel is also calling at Baobab, 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 Espoir
Do you provide in-water class survey at Espoir Marine Terminal?
Yes. Cleanship Marine works Espoir Marine Terminal (CIESP) in Block CI-26, Côte d'Ivoire, covering the FPSO Espoir Ivoirien on station, shuttle tanker offloading area and field support vessel moorings. Teams mobilise via Abidjan (ABJ) with the full spread.
How is an FPSO like Espoir Ivoirien surveyed for class?
In the water, because she cannot go to a dry dock without stopping production. The survey programme is agreed with the class society and the operator in advance, covering the hull, sea chests and moorings, and fitted around production and offloading with live video to the surveyor.
Can in-water class survey be done while the vessel works cargo at Espoir?
Only within the operator's permit system. On the FPSO, in-water work is planned around production and offloading; on a shuttle tanker, it is done while she waits in the field rather than during a connected offloading. The vessel stays on hire throughout, and there is no diversion and no dry dock. We scope against the conditions at Espoir and tell you honestly whether the window you have is enough.
Do you need a diving permit from CNR International?
Yes, and we obtain it. Diving permission from CNR International, 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 Espoir?
Visibility at Espoir Marine Terminal is good — this is clear open-sea water well offshore — so the swell and the field's operations rather than visibility decide the window, 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 Espoir?
FPSO Espoir Ivoirien, Shuttle tankers and Offshore support vessels — the traffic at Espoir Marine Terminal runs to crude oil and associated gas piped ashore, 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 Espoir?
Divers and equipment mobilise via Abidjan (ABJ). 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 Baobab or Lion, one mobilisation is often sized to cover both.
What does in-water class survey at Espoir cost?
It depends on the vessel's dimensions and wetted area, the fouling state found, the coating specification and the working window available at Espoir. 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 Espoir and you get a scoped price, usually the same working day.
