Cleanship Marine provides underwater hull cleaning at Mangalore Port, Karnataka, working the liquid berths and dry bulk berths. Commercial dive teams remove slime, weed and shell growth from the vertical sides, flat bottom, bilge keels, sea chests and niche areas with the vessel afloat and on hire — no dry dock, no diversion, no off-hire.
New Mangalore is a major port built around liquid bulk — crude for the local refinery, LPG and edible oil — with iron ore pellets and containers alongside. Tanker tonnage working to tight terminal windows dominates, so an underwater scope here is normally sized to fit a single berth slot end to end.
What it gets you
- Hydrodynamic smoothness restored before fouling reaches the calcareous stage that damages coating
- Fuel and emissions penalty from drag reduced without taking the vessel off hire
- Documented condition record for the technical file and the next docking specification
- Sea chests and inlets cleared, protecting cooling water flow
Working conditions at Mangalore
New Mangalore is a breakwater harbour with reasonably clear Arabian Sea water, so in-water inspection here yields video that is genuinely usable for a class file rather than a formality. The south-west monsoon from June to September is the limiting season for anchorage work, while the basin stays workable longer. Tanker and LPG berths bring terminal permit requirements on top of the port's diving permission, so the approval chain runs through the terminal as well as the harbour master.

What we do at Mangalore
- Pre-clean fouling survey to establish coverage, growth type and coating condition before any tool touches the hull
- Brush cart cleaning of the flat bottom and vertical sides, with brush hardness selected against your antifouling specification
- Hand cleaning of bilge keels, rudder, stern frame, thruster tunnels, anodes and the niches a cart cannot follow
- Sea chest gratings and inlet openings cleared of growth and debris to restore cooling water flow
- Diving permission cleared with New Mangalore Port Authority and the terminal before mobilisation
- Before-and-after video and stills, with a written report on coating condition and anode wastage
Planning the window at Mangalore
The south-west monsoon governs the calendar at Mangalore 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 liquid berths, dry bulk berths and outer anchorage, and which of those a vessel ends up at changes the dive plan more than the season does. Teams mobilise via Mangaluru (IXE), 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 Mangalore
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 Mangalore 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.
Standard scope of work
Included as standard on every underwater hull cleaning attendance, wherever the vessel is. Anything outside it is quoted separately and flagged before mobilisation, never added afterwards.
- Fouling survey
- A pre-clean dive establishes fouling type, coverage and severity, and confirms coating condition so the correct tooling is selected.
- Flat bottom and vertical sides
- Brush cart cleaning of large areas, removing slime, weed and shell growth to restore surface smoothness.
- Niche areas
- Hand cleaning of bilge keels, bow thruster tunnels, rudder, stern frame, anodes and other niche areas where fouling concentrates.
- Sea chests and gratings
- Sea chest gratings and inlet openings cleared of growth and debris to restore cooling water flow.
- Documentation
- Underwater video and stills before and after, with a written report covering coating condition and anode wastage.
How we deliver it at Mangalore
- 1
Scope and vessel details
Tell us the vessel, her particulars, the coating specification and the window at Mangalore. 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 New Mangalore 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 Mangalore
Divers, compressors, brush carts and cameras mobilise via Mangaluru (IXE). Where a vessel is also calling at Cochin, 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 underwater 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.

Frequently asked — Underwater Hull Cleaning at Mangalore
Do you provide underwater hull cleaning at Mangalore Port?
Yes. Cleanship Marine works Mangalore Port (INIXE) in Karnataka, India, covering the liquid berths, dry bulk berths and outer anchorage. Teams mobilise via Mangaluru (IXE) with the full spread.
Can underwater hull cleaning be done while the vessel works cargo at Mangalore?
Yes. Conditions here are good enough that the dive runs alongside cargo operations without either holding the other up, and the work is documented on video as it goes. The vessel stays on hire throughout, and there is no diversion and no dry dock. We scope against the conditions at Mangalore and tell you honestly whether the window you have is enough.
Do you need a diving permit from New Mangalore Port Authority?
Yes, and we obtain it. Diving permission from New Mangalore Port Authority, terminal approval where the berth requires it, and any environmental clearance for in-water work are arranged as part of the job rather than left with the agent. The master's permit to work and the immobilisation of machinery are agreed on board before anyone enters the water.
What is underwater visibility like at Mangalore?
Visibility at Mangalore Port is good by regional standards and usually adequate for video work, 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.
Which vessels do you carry out underwater hull cleaning on at Mangalore?
Crude and product tankers, LPG carriers, Bulk carriers, Feeder container ships — the traffic at Mangalore Port runs to crude and pol, lpg, iron ore pellets, 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 Mangalore?
Divers and equipment mobilise via Mangaluru (IXE). 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 Cochin or Karwar, one mobilisation is often sized to cover both.
What does underwater hull cleaning at Mangalore cost?
It depends on the vessel's dimensions and wetted area, the fouling state found, the coating specification and the working window available at Mangalore. 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 Mangalore and you get a scoped price, usually the same working day.
