Cleanship Marine provides the full underwater scope at Dahej Port (INDAH), Gujarat — 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.

Dahej is Gujarat's principal LNG and liquid chemical gateway, with a solid cargo terminal alongside it serving the Bharuch industrial belt. Gas carriers and chemical tankers working to strict terminal windows dominate the traffic, so an underwater scope here is sized to the slot that exists, and anything that will not fit is staged for the next call.

Working conditions at Dahej

Dahej sits in the Gulf of Khambhat, where the tidal range is extreme and the streams run hard, so diving is cut to slack-water windows and planned strictly against the tide table rather than the berth schedule. The water is heavily silted and visibility is habitually very low, which makes this a touch-and-supervision job with video kept for the record. Gas and chemical terminals add a permit layer on top of port clearance, so the terminal operator has to be in the approval chain from the start, not brought in at the gangway.

Hull Cleaning scopes at Dahej

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

Planning the window at Dahej

The south-west monsoon governs the calendar at Dahej 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. The tidal stream and the silt load govern the method here: the working window is slack water, not the working day, and the operation is planned by feel and surface supervision with video kept as the record rather than as the diver's means of navigation.

Work is taken at the LNG jetty, liquid chemical terminal and solid cargo berths, and which of those a vessel ends up at changes the dive plan more than the season does. Teams mobilise via Vadodara (BDQ) or Surat (STV), 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 Dahej

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 Dahej than owners budget for.

Silt settles over the growth on the flat bottom and in the niches, which masks the true fouling state until the divers are actually on it. That is why the pre-clean survey here is a real step rather than a formality.

How we deliver it at Dahej

1
Scope and vessel details
Tell us the vessel, her particulars, the coating specification and the window at Dahej. 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 Gujarat 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 Dahej
Divers, compressors, brush carts and cameras mobilise via Vadodara (BDQ) or Surat (STV). Where a vessel is also calling at Hazira, 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 Dahej Port (INDAH), Gujarat — underwater hull cleaning, propeller polishing, thruster cleaning & polishing, in-water class survey and uwild. Teams mobilise via Vadodara (BDQ) or Surat (STV).

What is underwater visibility like at Dahej?

Visibility at Dahej Port is habitually very low, and often close to nil at the turn, 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 Dahej?

Gujarat Maritime Board issues the port-side approval at Dahej 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 Dahej?

LNG carriers, Chemical and product tankers, Bulk carriers — Dahej Port is gas and chemical terminal windows in a hard-running tidal gulf, handling lng, liquid chemicals, coal, fertiliser, steel 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 Dahej?

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 Dahej?

Yes. Hazira, Magdalla and Bhavnagar 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.
