Cleanship Marine carries out cargo tank cleaning on dirty and clean petroleum product tankers at Jubail Port, Eastern Province — grade changes, wall-wash preparation and gas-freeing worked to the acceptance criteria of the next cargo, not to a generic procedure.
Jubail loads chemical and polymer grades to strict specification, so the cleaning plan is built from the prior-cargo and next-cargo pair and the charterer's acceptance criteria, not from a standard procedure. Gas-freeing, marine chemist attendance and enclosed-space entry certification are the critical path, and terminal approval for any work alongside has to be in hand before arrival.
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 Jubail
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 Mawani and the Royal Commission for Jubail 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.

- 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 Jubail with documentation
- Tank-by-tank record and a completion report for the vessel and the charterer
Planning the window at Jubail
The shamal governs the calendar at Jubail Port, through the winter months and again in early summer. For tank work it is the anchorage that suffers — where the terminal will not permit work alongside, weather that closes the anchorage closes the job. 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 Dammam (DMM), 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 Jubail
Chemical and petrochemical grades move through here, so the cleaning specification changes with almost every voyage and is set by the next charterer's acceptance criteria. The wash plan is built from the prior-cargo and next-cargo pair, not from a standard procedure.
Tanks here are usually presented with a machine wash already done and the hand work outstanding — bottom structure, suction wells, heating coils and the areas the machines cannot reach. That remainder is what a wall wash actually fails on.
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 Jubail
- 1
Scope and vessel details
Tell us the vessel, her particulars, the prior and next grade and the window at Jubail. 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
Mawani and the Royal Commission for Jubail runs a statutory permit process here, so the lead time is real and the application goes in early rather than on arrival. Licensed slop and sludge reception is booked and marine chemist attendance arranged where the grade change requires it. At Jubail the disposal route is the item that most often sets the schedule, so it is fixed first.
- 3
Mobilisation to Jubail
Crews, pumps, machines and chemicals mobilise via Dammam (DMM). Where a vessel is also calling at Dammam, 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 Jubail
Do you provide tanker tank cleaning at Jubail Port?
Yes. Cleanship Marine works Jubail Port (SAJBI) in Eastern Province, Saudi Arabia, covering the chemical and liquid berths, general cargo quays, outer anchorage. Teams mobilise via Dammam (DMM) with the full spread.
Can tanker tank cleaning be done while the vessel works cargo at Jubail?
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 Jubail and tell you honestly whether the window you have is enough.
How is slop and sludge disposal handled at Jubail?
Through licensed reception, booked with Mawani and the Royal Commission for Jubail and the terminal operator before the tanks are opened. At Jubail 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 Jubail — 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 Jubail?
Chemical and product tankers, LPG carriers, Bulk carriers, General cargo and project vessels — the traffic at Jubail Port runs to petrochemicals, liquid chemicals and sulphur, 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 Jubail?
Crews and equipment mobilise via Dammam (DMM). 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 Yanbu, one mobilisation is often sized to cover both.
What does tanker tank cleaning at Jubail 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 Jubail. 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 Jubail and you get a scoped price, usually the same working day.
