Cleanship Marine carries out cargo tank cleaning on dirty and clean petroleum product tankers at Mumbai Port, Maharashtra — grade changes, wall-wash preparation and gas-freeing worked to the acceptance criteria of the next cargo, not to a generic procedure.
Mumbai Port handles liquid bulk at Jawahar Dweep, general and project cargo in the docks, and serves as the shore base for offshore activity in the Bombay High field. The offshore support fleet working out of here is one of the most regular users of in-water cleaning and survey anywhere in India.
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 Mumbai
Most of the work at this port happens at the anchorage, simply because that is where vessels spend their 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 Mumbai 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.

What we do at Mumbai
- 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 Mumbai with documentation
- Tank-by-tank record and a completion report for the vessel and the charterer
Planning the window at Mumbai
The south-west monsoon governs the calendar at Mumbai 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. The waiting time here is what makes the job practical. Tanks can be worked at anchorage under a proper entry regime rather than squeezed against a berth clock, which is the difference between a specification clean and a visual one.
Teams mobilise via Mumbai (BOM), 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 Mumbai
Liquid bulk at Mumbai works through Jawahar Dweep and Pir Pau, and tank cleaning at those jetties is governed by terminal rules rather than port rules. Slop reception, gas-freeing and any hot work permit are agreed with the terminal before the vessel sails in.
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 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 Mumbai
- 1
Scope and vessel details
Tell us the vessel, her particulars, the prior and next grade and the window at Mumbai. 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 Mumbai 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 Mumbai the disposal route is the item that most often sets the schedule, so it is fixed first.
- 3
Mobilisation to Mumbai
Crews, pumps, machines and chemicals mobilise via Mumbai (BOM). Where a vessel is also calling at Nhava Sheva, 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 Mumbai
Do you provide tanker tank cleaning at Mumbai Port?
Yes. Cleanship Marine works Mumbai Port (INBOM) in Maharashtra, India, covering the Indira and Jawahar dock berths, Jawahar Dweep and Pir Pau oil jetties, harbour anchorages. Teams mobilise via Mumbai (BOM) with the full spread.
Can tanker tank cleaning be done while the vessel works cargo at Mumbai?
Usually not at the berth — but that matters less here, because vessels wait. Tank work is taken at the anchorage under a full entry regime, which gives a specification clean the time it actually needs. The vessel stays on hire throughout, and there is no diversion and no dry dock. We scope against the conditions at Mumbai and tell you honestly whether the window you have is enough.
How is slop and sludge disposal handled at Mumbai?
Through licensed reception, booked with Mumbai Port Authority and the terminal operator before the tanks are opened. At Mumbai 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 Mumbai — alongside, at anchorage or on passage?
Most of the work at this port happens at the anchorage, simply because that is where vessels spend their time.
Which vessels do you carry out tanker tank cleaning on at Mumbai?
Crude and product tankers, General cargo ships, Offshore support vessels, Cruise ships, Harbour craft and tugs — the traffic at Mumbai Port runs to pol, general and project cargo, steel, 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 Mumbai?
Crews and equipment mobilise via Mumbai (BOM). 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 Nhava Sheva, one mobilisation is often sized to cover both.
What does tanker tank cleaning at Mumbai 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 Mumbai. 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 Mumbai and you get a scoped price, usually the same working day.
