Cleanship Marine cleans offshore support vessel tanks at Mormugao Port, Goa — 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 Mormugao
Work here runs both alongside and at anchorage depending on the call, and on the passage out where neither gives enough time. The south-west monsoon sets the outer limits of the calendar, roughly June to September, and it affects the anchorage far more than the berth. Approval runs through Mormugao Port 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 Mormugao
The south-west monsoon governs the calendar at Mormugao Port, roughly June to September. Swell and reduced surface visibility close most open-water work on this coast for the duration, and the weeks either side are unreliable rather than unusable. 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 Goa (GOI), 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 Mormugao
The liquid side at Mormugao is product parcels and bunkers rather than crude, so the work is grade changes and fuel tank cleaning. Barge and small-craft tank work runs as a steady second stream alongside it.
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 Mormugao

Scope and vessel details
Tell us the vessel, her particulars, the prior and next grade and the window at Mormugao. 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.

Approvals, slops and certification
Terminal and port approval for tank work is obtained from Mormugao Port 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 Mormugao the disposal route is the item that most often sets the schedule, so it is fixed first.
- 3
Mobilisation to Mormugao
Crews, pumps, machines and chemicals mobilise via Goa (GOI). Where a vessel is also calling at Karwar, 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 Mormugao
Do you provide offshore vessel tank cleaning at Mormugao Port?
Yes. Cleanship Marine works Mormugao Port (INMRM) in Goa, India, covering the inner harbour berths, breakwater berths and anchorage. Teams mobilise via Goa (GOI) with the full spread.
Can offshore vessel tank cleaning be done while the vessel works cargo at Mormugao?
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 Mormugao and tell you honestly whether the window you have is enough.
How is slop and sludge disposal handled at Mormugao?
Through licensed reception, booked with Mormugao Port Authority and the terminal operator before the tanks are opened. At Mormugao 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 Mormugao — 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.
Which vessels do you carry out offshore vessel tank cleaning on at Mormugao?
Panamax and Capesize bulk carriers, Container ships, Cruise ships, Ore barges and tugs — the traffic at Mormugao Port runs to coal, iron ore and containers, 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 Mormugao?
Crews and equipment mobilise via Goa (GOI). 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 Mormugao 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 Mormugao. 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 Mormugao and you get a scoped price, usually the same working day.
