Cleanship Marine carries out cargo tank cleaning on dirty and clean petroleum product tankers at Ruwais Port, Abu Dhabi — grade changes, wall-wash preparation and gas-freeing worked to the acceptance criteria of the next cargo, not to a generic procedure.
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.
What it gets you
- Tanks presented to the standard the next charterer will actually accept
- Wall-wash failures and the resulting rejection or delay avoided
- Slop disposal documented through licensed reception, not improvised
- Entry and gas-freeing certified rather than assumed
Working conditions at Ruwais
Work here starts alongside, and where the berth window runs out it continues on the outward passage with a riding crew — the berth will not be held open for it. The shamal sets the outer limits of the calendar, through the winter months and again in early summer, and it affects the anchorage far more than the berth. The larger constraint here is heat. Between June and September, working temperatures inside a cargo hold or a tank at this port routinely exceed anything a full shift can be worked in, so enclosed-space work runs to shortened cycles with enforced rest, forced ventilation and more people than the same job needs in winter. Pricing a Gulf summer tank entry on a winter productivity assumption is the most common way these jobs overrun. Approval runs through AD Ports Group and the terminal operator and the terminal operator, and licensed slop reception is booked before the tanks are opened — at most ports on this list that booking, not the cleaning, is what sets the date.

What we do at Ruwais
- Cleaning plan built from the prior-cargo and next-cargo pair, with the acceptance criteria agreed in writing first
- Tank washing, steaming and chemical treatment as the grade change requires
- Gas-freeing, atmosphere testing and enclosed-space entry certification before any entry
- Hand mopping, wall wash and final presentation for surveyor inspection
- Slops and residues transferred to licensed reception at Ruwais with documentation
- Tank-by-tank record and a completion report for the vessel and the charterer
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. Terminal windows here are tight and most operators will not permit tank work alongside, so the realistic plan is the anchorage or the outward passage. That is agreed before the vessel arrives, not argued at the berth.
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
Ruwais loads crude, product and petrochemical grades to strict specification, so tank cleaning here is driven by the next cargo and the terminal's acceptance criteria. Gas-freeing, marine chemist attendance and enclosed-space entry certification are arranged as part of the scope, and work at the berth needs the terminal's approval in advance.
Gas and specialised liquid tonnage calls here, which puts the certification chain ahead of the cleaning itself: gas-freeing, marine chemist attendance and enclosed-space entry certificates are the critical path, and the physical work is the short part of the job.
Standard scope of work
Included as standard on every tanker tank cleaning attendance, wherever the vessel is. Anything outside it is quoted separately and flagged before mobilisation, never added afterwards.
- Pre-clean assessment
- Cargo history, tank coating condition, heating coil status and the next cargo specification are reviewed to fix the cleaning method and realistic acceptance criteria.
- Machine washing
- Fixed and portable tank cleaning machines run to a calculated cycle programme, using hot or cold sea water, fresh water and approved chemicals as the cargo pair requires.
- Hand hosing and manual finishing
- Bellmouths, suction wells, framing, heating coils and structural shadows are hand-hosed and manually finished — the areas machines geometrically cannot reach.
- Draining, mopping and drying
- Tanks are stripped, mopped and dried so no free water or residue remains to contaminate the next grade or skew the wall wash result.
- Gas-freeing and verification
- Ventilation to safe-for-entry or gas-free-for-hot-work condition, with continuous monitoring and independent certification arranged where required.
How we deliver it at Ruwais
- 1
Scope and vessel details
Tell us the vessel, her particulars, the prior and next grade 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
Approvals, slops and certification
Terminal and port approval for tank work is obtained from AD Ports Group and the terminal operator and the terminal operator, licensed slop and sludge reception is booked, and marine chemist attendance is arranged where the grade change requires it. At Ruwais the disposal route is the item that most often sets the schedule, so it is fixed first.
- 3
Mobilisation to Ruwais
Crews, pumps, machines and chemicals 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
Gas-freeing, entry and cleaning
Atmosphere testing, gas-freeing and enclosed-space entry certification come before any entry, and are repeated after every break. Standby cover and atmosphere monitoring run continuously while anyone is inside, and progress is reported tank by tank.
- 5
Report and handover
A completion report covering tanker tank cleaning is issued with before-and-after imagery, tank by tank and anything found that you should know about. The findings are discussed with the vessel rather than emailed and forgotten.

Frequently asked — Tanker Tank Cleaning at Ruwais
Do you provide tanker tank cleaning at Ruwais Port?
Yes. Cleanship Marine works Ruwais Port (AERUW) in Abu Dhabi, United Arab Emirates, covering the crude loading berths, product jetties and sulphur berth. Teams mobilise via Abu Dhabi (AUH) or Dubai (DXB) with the full spread.
Can tanker tank cleaning be done while the vessel works cargo at Ruwais?
Most terminals here will not permit tank work alongside, so the plan is the anchorage or the outward passage. We confirm the terminal's position before quoting rather than discovering it at the gangway. The vessel stays on hire throughout, and there is no diversion and no dry dock. We scope against the conditions at Ruwais and tell you honestly whether the window you have is enough.
How is slop and sludge disposal handled at Ruwais?
Through licensed reception, booked with AD Ports Group and the terminal operator and the terminal operator before the tanks are opened. At Ruwais the disposal route is usually what sets the schedule, so it is fixed first and documented tank by tank. Gas-freeing, atmosphere testing and enclosed-space entry certification are part of the same scope.
Where is the work done at Ruwais — alongside, at anchorage or on passage?
Work here starts alongside, and where the berth window runs out it continues on the outward passage with a riding crew — the berth will not be held open for it. Between June and September the binding constraint is working temperature inside the space rather than access to it.
Which vessels do you carry out tanker tank cleaning on at Ruwais?
VLCC and Suezmax crude tankers, Product and chemical tankers, LPG carriers, Sulphur bulk carriers — the traffic at Ruwais Port runs to crude oil, refined products and petrochemicals, 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 Ruwais?
Crews 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 Jebel Ali, one mobilisation is often sized to cover both.
What does tanker tank cleaning at Ruwais cost?
It depends on the tank count and volume, the prior and next grade, how much sludge is in there and whether the work runs alongside, at anchorage or on passage from Ruwais. 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 Ruwais and you get a scoped price, usually the same working day.
