Cleanship Marine provides the full underwater scope at Nhava Sheva Port (INNSA), Maharashtra — hull cleaning, propeller super polishing, bow and stern thruster work, class-approved in-water survey and UWILD. Every scope is carried out with the vessel afloat and on hire, at the berth or at the anchorage.

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.

Working conditions at Nhava Sheva

Nhava Sheva sits inside Mumbai harbour, so it is sheltered and anchorage work runs through most of the year with the south-west monsoon the main interruption. Container terminal windows are tight and productivity-driven, so a hull clean has to be scoped to run in parallel with cargo work and never to hold the berth. Harbour water is silty with moderate to low visibility, so survey-grade video is planned for, not assumed.

Hull Cleaning scopes at Nhava Sheva

5 scopes, one team and one mobilisation. Most vessels calling here take more than one on the same attendance.

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. Because the harbour is sheltered, work here normally runs alongside or at a protected anchorage and can proceed in parallel with cargo operations rather than competing with them for the berth window.

Work is taken at the container terminal berths, liquid berth and harbour anchorage, and which of those a vessel ends up at changes the dive plan more than the season does. 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 and gas tonnage here spends long stretches at the terminal or waiting for a slot, so growth tends to be even and well established across the hull rather than patchy — heavier than the trading pattern suggests, and further along than a speed report alone would indicate.

Shelter is a mixed blessing for a hull. The same calm that makes the port easy to work in is still water, and still water grows fouling faster than an exposed berth does.

How we deliver it at Nhava Sheva

1
Scope and vessel details
Tell us the vessel, her particulars, the coating specification 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
Permits and approvals
Diving permission is obtained from Jawaharlal Nehru Port Authority, along with terminal approval where the berth requires it and any environmental clearance for in-water work. This is handled by us, not left with the agent to chase.
3
Mobilisation to Nhava Sheva
Divers, compressors, brush carts and cameras mobilise via Mumbai (BOM). Where a vessel is also calling at Mumbai, one mobilisation is normally sized to cover both.
4
Safety setup and the dive
The vessel is secured for diving — main engine, shaft and thrusters immobilised, sea suctions confirmed shut, permit agreed with the master. Teams work under surface supervision with continuous diver communications and video throughout.
5
Report and handover
A completion report covering hull cleaning is issued with before-and-after imagery, coating and anode condition and anything found that you should know about. The findings are discussed with the vessel rather than emailed and forgotten.

Yes. We cover the full hull cleaning scope at Nhava Sheva Port (INNSA), Maharashtra — underwater hull cleaning, propeller polishing, thruster cleaning & polishing, in-water class survey and uwild. Teams mobilise via Mumbai (BOM).

What is underwater visibility like at Nhava Sheva?

Visibility at Nhava Sheva Port is moderate, and it drops further around active bulk handling and after heavy rain, and the south-west monsoon sets the outer limits of the calendar. How the tide and sea state shape the dive plan is set out in full in the working-conditions section on this page.

Who approves hull cleaning work at Nhava Sheva?

Jawaharlal Nehru Port Authority issues the port-side approval at Nhava Sheva Port, with terminal approval on top where the berth requires it. We arrange both, along with any environmental clearance for in-water cleaning, so it does not fall to the agent or the master.

Which vessels call at Nhava Sheva?

Main-line and feeder container ships, Product tankers — Nhava Sheva Port is India's largest container port on a fixed liner rotation, handling containers, liquid bulk and project cargo. Those are the profiles we see most, and the scope is sized to the vessel rather than to a standard package.

Can this be done without taking the vessel off hire at Nhava Sheva?

Yes — that is the point of it. Every scope listed here is carried out with the vessel afloat and working, at the berth, at the anchorage or on the passage out. Divers work with the vessel afloat at the berth or the anchorage, so there is no dry dock, no diversion and no off-hire.

Do you cover other ports near Nhava Sheva?

Yes. Mumbai, Dahanu and Ratnagiri all sit within the same operating range for hull cleaning, and a single mobilisation is often sized to cover more than one vessel on the same trip. We work 46 ports on the coverage list for this line.
