Cleanship Marine delivers class-approved in-water surveys at Khalifa Port, Abu Dhabi, 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. Shelter is on your side here — the vessel is stable and the dive is uninterrupted — but basin silt means the lighting and camera plan has to be agreed with the surveyor before the class attendance is booked, not improvised on the day.
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 Khalifa Port
Khalifa Port is a modern offshore island terminal behind a breakwater, so it is well sheltered and work alongside runs year-round against the berth window rather than the weather. The approach channel is dredged and the basin carries suspended sediment, so visibility is moderate. As everywhere inside the Gulf, water temperature and salinity mean fouling returns faster than the same vessel's northern-trade interval would suggest.

Planning the window at Khalifa Port
The shamal governs the calendar at Khalifa Port, through the winter months and again in early summer. The shamal is a wind and sea-state problem rather than a rain one: it builds short, steep seas across the shallow Gulf that stop anchorage work while berths stay usable. Because the harbour is sheltered, work here normally runs alongside or at a protected anchorage and can proceed in parallel with cargo operations rather than competing with them for the berth window.
Work is taken at the container terminal berths, general cargo and RoRo berths, dry bulk berths, anchorage, and which of those a vessel ends up at changes the dive plan more than the season does. Teams mobilise via Abu Dhabi (AUH) or Dubai (DXB), 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 Khalifa Port
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.
Shelter is a mixed blessing for a hull. The same calm that makes the port easy to work in is still water, and still water grows fouling faster than an exposed berth does.
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 Khalifa Port
- 1
Scope and vessel details
Tell us the vessel, her particulars, the coating specification and the window at Khalifa Port. 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
Diving permission is obtained from AD Ports Group and Abu Dhabi Maritime, along with terminal approval where the berth requires it and any environmental clearance for in-water work. This is handled by us, not left with the agent to chase.
- 3
Mobilisation to Khalifa Port
Divers, compressors, brush carts and cameras mobilise via Abu Dhabi (AUH) or Dubai (DXB). Where a vessel is also calling at Zayed Port, 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 Khalifa Port
Do you provide in-water class survey at Khalifa Port?
Yes. Cleanship Marine works Khalifa Port (AEKHL) in Abu Dhabi, United Arab Emirates, covering the container terminal berths, general cargo and RoRo berths, dry bulk berths, anchorage. Teams mobilise via Abu Dhabi (AUH) or Dubai (DXB) with the full spread.
Can in-water class survey be done while the vessel works cargo at Khalifa Port?
Yes, in most cases. The harbour is sheltered enough that divers work alongside while cargo operations continue, and neither holds the other up. The vessel stays on hire throughout, and there is no diversion and no dry dock. We scope against the conditions at Khalifa Port and tell you honestly whether the window you have is enough.
Do you need a diving permit from AD Ports Group and Abu Dhabi Maritime?
Yes, and we obtain it. Diving permission from AD Ports Group and Abu Dhabi Maritime, 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 Khalifa Port?
Visibility at Khalifa Port is moderate, and it drops further around active bulk handling and after heavy rain, and the shamal 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 Khalifa Port?
Main-line and feeder container ships, Bulk carriers, General cargo and project vessels — the traffic at Khalifa Port runs to containers, general and project cargo, dry bulk, 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 Khalifa Port?
Divers and equipment mobilise via Abu Dhabi (AUH) or Dubai (DXB). 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 Zayed Port or Ruwais, one mobilisation is often sized to cover both.
What does in-water class survey at Khalifa Port cost?
It depends on the vessel's dimensions and wetted area, the fouling state found, the coating specification and the working window available at Khalifa Port. 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 Khalifa Port and you get a scoped price, usually the same working day.
