Cleanship Marine provides underwater hull cleaning at Paradip Port, Odisha, working the dry bulk berths and oil jetty. 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.
Paradip is Odisha's major port and one of India's highest-tonnage dry bulk ports, serving the eastern steel, power and refining belt. Large bulk carriers and crude tankers on repeat voyages make it a port where hull and propeller condition translate directly into voyage economics.
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 Paradip
Paradip is a deep-draft artificial harbour taking Capesize tonnage, so hull jobs here are large and need proper crew sizing rather than an optimistic estimate. The Bay of Bengal cyclone seasons are the governing risk at the anchorage, and the harbour itself can build swell in bad weather. Bulk handling puts coal and ore dust into the basin, so visibility at the dry bulk berths is habitually poor and any survey scope should be priced on that basis.

What we do at Paradip
- 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 Paradip 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 Paradip
The north-east monsoon governs the calendar at Paradip Port, roughly October to December. The Bay of Bengal also carries cyclone risk in April to June and again from October to December, so an anchorage attendance on this coast is planned with a standby allowance rather than a single fixed date. 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 dry bulk berths, oil jetty and outer anchorage, and which of those a vessel ends up at changes the dive plan more than the season does. Teams mobilise via Bhubaneswar (BBI), 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 Paradip
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 Paradip than owners budget for.
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.
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 Paradip
- 1
Scope and vessel details
Tell us the vessel, her particulars, the coating specification and the window at Paradip. 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 Paradip 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 Paradip
Divers, compressors, brush carts and cameras mobilise via Bhubaneswar (BBI). Where a vessel is also calling at Dhamra, 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 Paradip
Do you provide underwater hull cleaning at Paradip Port?
Yes. Cleanship Marine works Paradip Port (INPRT) in Odisha, India, covering the dry bulk berths, oil jetty and outer anchorage. Teams mobilise via Bhubaneswar (BBI) with the full spread.
Can underwater hull cleaning be done while the vessel works cargo at Paradip?
Yes, in most cases. The harbour is sheltered enough that divers work alongside while cargo operations continue, and neither holds the other up. The vessel stays on hire throughout, and there is no diversion and no dry dock. We scope against the conditions at Paradip and tell you honestly whether the window you have is enough.
Do you need a diving permit from Paradip Port Authority?
Yes, and we obtain it. Diving permission from Paradip 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 Paradip?
Visibility at Paradip Port is moderate, and it drops further around active bulk handling and after heavy rain, and the north-east 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 Paradip?
Capesize and Panamax bulk carriers, Crude and product tankers — the traffic at Paradip Port runs to thermal and coking coal, iron ore, crude and pol, 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 Paradip?
Divers and equipment mobilise via Bhubaneswar (BBI). 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 Dhamra or Haldia, one mobilisation is often sized to cover both.
What does underwater hull cleaning at Paradip cost?
It depends on the vessel's dimensions and wetted area, the fouling state found, the coating specification and the working window available at Paradip. 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 Paradip and you get a scoped price, usually the same working day.
