Cleanship Marine provides the full underwater scope at Ruwais Port (AERUW), Abu Dhabi — 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.

Ruwais is the UAE's largest refining and petrochemical export complex, loading crude, refined products, LPG and sulphur to dedicated berths. The tonnage is large and specialised, and the port calls are governed end to end by terminal windows.

Working conditions at Ruwais

Ruwais is a refinery and petrochemical complex with dedicated loading berths, so it is sheltered and the working constraint is the terminal, not the weather. Access is controlled and the permit chain runs through the terminal operator as well as the port — for a gas or crude berth that is a lead time, not a formality. Gulf water here is shallow, warm and hypersaline with moderate visibility.

Where we work: Crude loading berths · Product jetties · Sulphur berth
Vessels we see here: VLCC and Suezmax crude tankers · Product and chemical tankers · LPG carriers · Sulphur bulk carriers

Hull Cleaning scopes at Ruwais

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

Planning the window at Ruwais

The shamal governs the calendar at Ruwais 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 crude loading berths, product jetties and sulphur berth, 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 Ruwais

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 Ruwais than owners budget for.

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.

How we deliver it at Ruwais

1
Scope and vessel details
Tell us the vessel, her particulars, the coating specification and the window at Ruwais. 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 the terminal operator, 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 Ruwais
Divers, compressors, brush carts and cameras mobilise via Abu Dhabi (AUH) or Dubai (DXB). Where a vessel is also calling at Khalifa 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 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 — Ruwais Port

Does Cleanship provide hull cleaning at Ruwais Port?

Yes. We cover the full hull cleaning scope at Ruwais Port (AERUW), Abu Dhabi — underwater hull cleaning, propeller polishing, thruster cleaning & polishing, in-water class survey and uwild. Teams mobilise via Abu Dhabi (AUH) or Dubai (DXB).

What is underwater visibility like at Ruwais?

Visibility at Ruwais 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.

Who approves hull cleaning work at Ruwais?

AD Ports Group and the terminal operator issues the port-side approval at Ruwais Port, 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 Ruwais?

VLCC and Suezmax crude tankers, Product and chemical tankers, LPG carriers, Sulphur bulk carriers — Ruwais Port is the UAE's largest refining and petrochemical export complex, handling crude oil, refined products, petrochemicals, lpg and sulphur. Those are the profiles we see most, and the scope is sized to the vessel rather than to a standard package.

Can this be done without taking the vessel off hire at Ruwais?

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 Ruwais?

Yes. Khalifa Port, Zayed Port and Jebel Ali 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 46 ports on the coverage list for this line.
