Cleanship Marine cleans cargo, bunker and shore tanks at Dahej Port (INDAH), Gujarat — grade changes on product and chemical tankers, sludge demucking, terminal storage tanks and offshore support vessel turnarounds. Gas-freeing, enclosed-space entry certification and licensed slop disposal are part of the scope, not extras.

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

Work here starts alongside, and where the berth window runs out it continues on the outward passage with a riding crew — the berth will not be held open for it. The south-west monsoon sets the outer limits of the calendar, roughly June to September, and it affects the anchorage far more than the berth. Approval runs through Gujarat Maritime Board and the terminal operator, and licensed slop reception is booked before the tanks are opened — at most ports on this list that booking, not the cleaning, is what sets the date.

Tank Cleaning scopes at Dahej

4 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. Terminal windows here are tight and most operators will not permit tank work alongside, so the realistic plan is the anchorage or the outward passage. That is agreed before the vessel arrives, not argued at the berth.

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

Dahej is LNG and liquid chemicals, so the certification chain runs ahead of the cleaning itself: gas-freeing, marine chemist attendance and enclosed-space entry certificates are the critical path, and the terminal sits in the approval chain from the start. Chemical grade changes here are set by the next charterer's acceptance criteria, not by a standard wash.

Gas and specialised liquid tonnage calls here, which puts the certification chain ahead of the cleaning itself: gas-freeing, marine chemist attendance and enclosed-space entry certificates are the critical path, and the physical work is the short part of the job.

How we deliver it at Dahej

1
Scope and vessel details
Tell us the vessel, her particulars, the prior and next grade 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
Approvals, slops and certification
Terminal and port approval for tank work is obtained from Gujarat Maritime Board and the terminal operator, licensed slop and sludge reception is booked, and marine chemist attendance is arranged where the grade change requires it. At Dahej the disposal route is the item that most often sets the schedule, so it is fixed first.
3
Mobilisation to Dahej
Crews, pumps, machines and chemicals mobilise via Vadodara (BDQ) or Surat (STV). Where a vessel is also calling at Hazira, one mobilisation is normally sized to cover both.
4
Gas-freeing, entry and cleaning
Atmosphere testing, gas-freeing and enclosed-space entry certification come before any entry, and are repeated after every break. Standby cover and atmosphere monitoring run continuously while anyone is inside, and progress is reported tank by tank.
5
Report and handover
A completion report covering tank cleaning is issued with before-and-after imagery, tank by tank and anything found that you should know about. The findings are discussed with the vessel rather than emailed and forgotten.

Who approves tank cleaning work at Dahej?

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. Tank work runs alongside where the terminal permits it, and otherwise at anchorage or on the passage out — none of which takes the vessel off hire.

Do you cover other ports near Dahej?

Yes. Hazira and Magdalla all sit within the same operating range for tank cleaning, and a single mobilisation is often sized to cover more than one vessel on the same trip. We work 24 ports on the coverage list for this line.
