Cleanship Marine provides the full underwater scope at Karwar Port (INKRW), Karnataka — 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.

Karwar is a state port in Uttara Kannada working bulk and general cargo, close to the naval base at Kadamba. Its comparatively clear Arabian Sea water makes it one of the better Indian ports for in-water class survey and UWILD work as well as for straightforward cleaning.

Working conditions at Karwar

Karwar is a sheltered bay port with good natural protection, so both alongside and anchorage work are practical outside the south-west monsoon. Water clarity here is markedly better than at the silt-laden Gujarat and Bengal ports, which changes what the job can deliver: video-documented inspection at Karwar produces evidence a surveyor can actually read, rather than a record of a black frame. The monsoon between June and September remains the limiting factor on the calendar.

Where we work: Berths inside the bay · Anchorage

Hull Cleaning scopes at Karwar

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

Planning the window at Karwar

The south-west monsoon governs the calendar at Karwar 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. Water clarity here is good by regional standards, so the operation can be properly documented on video as it happens — an advantage that turns a cleaning job into usable condition evidence at no extra mobilisation cost.

Work is taken at the berths inside the bay and anchorage, and which of those a vessel ends up at changes the dive plan more than the season does. Teams mobilise via Goa (GOI) or Hubballi (HBX), 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 Karwar

Dry bulk handling here puts cargo dust into the water around the berths and anchorage. It settles on horizontal surfaces and packs into sea chest gratings and inlet openings, so inlet and grating clearance is routinely a larger part of the job at Karwar than owners budget for.

Clearer water means the fouling state can be assessed properly before any tooling is selected, and the assessment can be shown to you rather than described.

How we deliver it at Karwar

1
Scope and vessel details
Tell us the vessel, her particulars, the coating specification and the window at Karwar. 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 Karnataka Maritime Board, 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 Karwar
Divers, compressors, brush carts and cameras mobilise via Goa (GOI) or Hubballi (HBX). Where a vessel is also calling at Belekeri, 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 Karwar?

Karnataka Maritime Board issues the port-side approval at Karwar 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 Karwar?

Handysize bulk carriers, General cargo ships, Support and naval auxiliary craft — Karwar Port is clear sheltered bay water suited to in-water survey, handling iron ore and bauxite, coal, sugar, general 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 Karwar?

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 Karwar?

Yes. Belekeri, Mormugao and Mangalore 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.
