Cleanship Marine carries out cargo tank cleaning on dirty and clean petroleum product tankers at Nhava Sheva Port, Maharashtra — grade changes, wall-wash preparation and gas-freeing worked to the acceptance criteria of the next cargo, not to a generic procedure.
Nhava Sheva, officially Jawaharlal Nehru Port, is India's largest container port and the main box gateway for western India. Liner container ships run fixed rotations here, which makes propeller polishing and hull cleaning a scheduled maintenance item on a known interval rather than an emergency response to a speed complaint.
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 Nhava Sheva
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 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 Jawaharlal Nehru 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 Nhava Sheva
- 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 Nhava Sheva with documentation
- Tank-by-tank record and a completion report for the vessel and the charterer
Planning the window at Nhava Sheva
The south-west monsoon governs the calendar at Nhava Sheva 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. 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 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 Nhava Sheva
Liquid bulk is a small part of a container port, so tank work at Nhava Sheva is mostly bunker, slop and fuel tank cleaning on box ships and harbour craft rather than cargo grade changes. Container berth windows will not carry it, so it is planned for the anchorage.
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 Nhava Sheva

Scope and vessel details
Tell us the vessel, her particulars, the prior and next grade and the window at Nhava Sheva. 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 Jawaharlal Nehru 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 Nhava Sheva the disposal route is the item that most often sets the schedule, so it is fixed first.
- 3
Mobilisation to Nhava Sheva
Crews, pumps, machines and chemicals mobilise via Mumbai (BOM). Where a vessel is also calling at Mumbai, 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 Nhava Sheva
Do you provide tanker tank cleaning at Nhava Sheva Port?
Yes. Cleanship Marine works Nhava Sheva Port (INNSA) in Maharashtra, India, covering the container terminal berths, liquid berth and harbour anchorage. Teams mobilise via Mumbai (BOM) with the full spread.
Can tanker tank cleaning be done while the vessel works cargo at Nhava Sheva?
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 Nhava Sheva and tell you honestly whether the window you have is enough.
How is slop and sludge disposal handled at Nhava Sheva?
Through licensed reception, booked with Jawaharlal Nehru Port Authority and the terminal operator before the tanks are opened. At Nhava Sheva 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 Nhava Sheva — 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.
Which vessels do you carry out tanker tank cleaning on at Nhava Sheva?
Main-line and feeder container ships, Product tankers — the traffic at Nhava Sheva Port runs to containers, liquid bulk and project cargo, 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 Nhava Sheva?
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 Mumbai, one mobilisation is often sized to cover both.
What does tanker tank cleaning at Nhava Sheva 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 Nhava Sheva. 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 Nhava Sheva and you get a scoped price, usually the same working day.
