Cleanship Marine cleans offshore support vessel tanks at Hamriyah Port, Sharjah — drilling mud, brine, base oil, cement and bulk tanks turned round between charters and prepared for the next product.
An OSV between charters is an asset earning nothing, and the tank turnaround is usually the item on the critical path. The products involved — mud, brine, base oil, cement — each leave a different residue and need a different method, so the plan is built product by product rather than tank by tank.
What it gets you
- Vessel handed to the next charter on time rather than held on the tank turnaround
- Cross-contamination between products avoided
- Inspection passed at the first attempt
- Disposal documented, not improvised
Working conditions at Hamriyah
Work here runs both alongside and at anchorage depending on the call, and on the passage out where neither gives enough time. 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 Sharjah Ports Authority 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.

Planning the window at Hamriyah
The shamal governs the calendar at Hamriyah 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. Whether the work runs alongside, at anchorage or on passage depends on the terminal and the grade, so the plan is built against the actual call. Where a terminal will not permit tank work at the berth, we say so at quoting stage rather than after mobilisation.
Teams mobilise via Sharjah (SHJ) 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 Hamriyah
Hamriyah handles product and chemical parcels alongside the offshore fleet, so tank scope ranges from a full grade change on a product tanker to fuel and slop tank cleaning on OSVs coming off charter. Slop disposal is arranged through licensed contractors in the free zone as part of the job.
Product parcels and bunkers dominate the liquid traffic here, so most of the work is grade changes and fuel and slop tank cleaning rather than full chemical specification work.
Standard scope of work
Included as standard on every offshore vessel tank cleaning attendance, wherever the vessel is. Anything outside it is quoted separately and flagged before mobilisation, never added afterwards.
- Fluid recovery and stripping
- Residual mud, brine and base oil are recovered and transferred to nominated tanks, road tankers or shore reception.
- Tank washing
- Machine and manual washing appropriate to the fluid type, with particular attention to settled solids in mud and cement tanks.
- Line and pump flushing
- Associated pipework, pumps and manifolds are flushed so cross-contamination does not reappear from the system after the tank is clean.
- Survey preparation
- Tanks are cleaned and dried to a condition suitable for coating inspection and class survey attendance.
- Waste management
- Recovered fluids and solids are consolidated and landed to licensed facilities with manifests issued.
How we deliver it at Hamriyah
- 1
Scope and vessel details
Tell us the vessel, her particulars, the prior and next grade and the window at Hamriyah. 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 Sharjah Ports Authority and the terminal operator, licensed slop and sludge reception is booked, and marine chemist attendance is arranged where the grade change requires it. At Hamriyah the disposal route is the item that most often sets the schedule, so it is fixed first.
- 3
Mobilisation to Hamriyah
Crews, pumps, machines and chemicals mobilise via Sharjah (SHJ) or Dubai (DXB). Where a vessel is also calling at Sharjah, 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.

Report and handover
A completion report covering offshore vessel 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 — OSV Tank Cleaning at Hamriyah
Do you provide offshore vessel tank cleaning at Hamriyah Port?
Yes. Cleanship Marine works Hamriyah Port (AEHAM) in Sharjah, United Arab Emirates, covering the free zone berths, oil and gas quays, bulk berths, anchorage. Teams mobilise via Sharjah (SHJ) or Dubai (DXB) with the full spread.
Can offshore vessel tank cleaning be done while the vessel works cargo at Hamriyah?
It depends on the terminal and the grade. Some berths here permit tank work alongside and some do not; we establish which before the vessel arrives and plan for the anchorage or the passage where the answer is no. The vessel stays on hire throughout, and there is no diversion and no dry dock. We scope against the conditions at Hamriyah and tell you honestly whether the window you have is enough.
How is slop and sludge disposal handled at Hamriyah?
Through licensed reception, booked with Sharjah Ports Authority and the terminal operator before the tanks are opened. At Hamriyah 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 Hamriyah — alongside, at anchorage or on passage?
Work here runs both alongside and at anchorage depending on the call, and on the passage out where neither gives enough time. Between June and September the binding constraint is working temperature inside the space rather than access to it.
Which vessels do you carry out offshore vessel tank cleaning on at Hamriyah?
General cargo and project vessels, Handysize bulk carriers, Offshore support vessels and barges, Product and chemical tankers — the traffic at Hamriyah Port runs to steel and project cargo, oil and gas equipment, aggregates and 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 Hamriyah?
Crews and equipment mobilise via Sharjah (SHJ) 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.
What does offshore vessel tank cleaning at Hamriyah 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 Hamriyah. 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 Hamriyah and you get a scoped price, usually the same working day.
