Cleanship Marine provides the full underwater scope at Mumbai Port (INBOM), 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.

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.

Working conditions at Mumbai

Mumbai harbour is well sheltered behind the mainland and the island, so anchorage work runs through most of the year with the south-west monsoon the main interruption. Harbour water is silty and traffic is dense, so dives are planned around vessel movements with a clear permit agreed with the master and the port. Long waits at the harbour anchorages are routine, and that idle time in warm harbour water is where the heaviest fouling in the region develops.

Where we work: Indira and Jawahar dock berths · Jawahar Dweep and Pir Pau oil jetties · Harbour anchorages
Vessels we see here: Crude and product tankers · General cargo ships · Offshore support vessels · Cruise ships · Harbour craft and tugs

Hull Cleaning scopes at Mumbai

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

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. 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 Indira and Jawahar dock berths, Jawahar Dweep and Pir Pau oil jetties, harbour anchorages, 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 Mumbai

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 Mumbai

1
Scope and vessel details
Tell us the vessel, her particulars, the coating specification 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
Permits and approvals
Diving permission is obtained from Mumbai 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 Mumbai
Divers, compressors, brush carts and cameras mobilise via Mumbai (BOM). Where a vessel is also calling at Nhava Sheva, 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.

Who approves hull cleaning work at Mumbai?

Mumbai Port Authority issues the port-side approval at Mumbai 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 Mumbai?

Crude and product tankers, General cargo ships, Offshore support vessels, Cruise ships, Harbour craft and tugs — Mumbai Port is sheltered harbour anchorages that grow heavy fouling, handling pol, general and project cargo, steel, cruise, offshore support. 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 Mumbai?

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 Mumbai?

Yes. Nhava Sheva, 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.
