Cleanship Marine runs full UWILD programmes — Underwater Inspection In Lieu of Drydocking — at Gangavaram Port, Andhra Pradesh, from eligibility discussion through class liaison to the final report package.
UWILD lets a vessel satisfy a survey requirement that would otherwise mean a dry docking, at a fraction of the cost and with none of the off-hire. The requirements are exacting: the contractor must hold class approval, the vessel must be eligible, hull markings must let the surveyor locate features precisely, and the inspection has to be delivered live and documented. Shelter is on your side here — the vessel is stable and the dive is uninterrupted — but basin silt means the lighting and camera plan has to be agreed with the surveyor before the class attendance is booked, not improvised on the day.
What it gets you
- Drydocking deferred and the survey credit earned in the water
- Class liaison handled end to end rather than left with the superintendent
- Eligibility confirmed before cost is committed, not discovered afterwards
- A documented inspection record that stands up to class review
Working conditions at Gangavaram
Gangavaram is a deep-draft all-weather port immediately south of Visakhapatnam, and its natural depth means fully laden Capesize vessels are worked alongside rather than at anchor — an advantage for hull cleaning, because a berthed vessel gives the team a stable platform and a predictable window. The site is sheltered enough to work through most of the year, with cyclone season the main interruption. Bulk dust settles in the basin, so visibility at the ore and coal berths runs lower than in the outer roads.

What we do at Gangavaram
- Eligibility review against the vessel's age, type, class notation and survey history before anything is booked
- Programme agreed with the class society and the surveyor attending at Gangavaram
- Hull, rudder, propeller, stern gear, sea chests and appendages inspected to the UWILD scope
- Live video, thickness measurement and clearance readings where the programme calls for them
- Diving permission cleared with Gangavaram Port Limited, with the vessel secured and machinery immobilised
- Complete report package submitted for the class file and the drydocking credit
Planning the window at Gangavaram
The north-east monsoon governs the calendar at Gangavaram 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 deep-draft 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 Visakhapatnam (VTZ), 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 Gangavaram
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 Gangavaram 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 UWILD attendance, wherever the vessel is. Anything outside it is quoted separately and flagged before mobilisation, never added afterwards.
- Eligibility and planning
- Vessel eligibility, survey scope and the society's specific requirements are established and agreed before mobilisation.
- Hull preparation
- Reference markings and cleaning of inspection areas so structure and features can be located and viewed unambiguously.
- Systematic inspection
- Shell plating, welds, rudder, propeller, sea chests, openings, anodes and appendages inspected to the agreed programme.
- Measurement and NDT
- Clearance measurement and underwater NDT carried out where the survey scope requires it.
- Documentation
- Video, stills, measurements and findings compiled into a report package suitable for submission to the classification society.
How we deliver it at Gangavaram
- 1
Scope and vessel details
Tell us the vessel, her particulars, the coating specification and the window at Gangavaram. 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 Gangavaram Port Limited, 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 Gangavaram
Divers, compressors, brush carts and cameras mobilise via Visakhapatnam (VTZ). Where a vessel is also calling at Visakhapatnam, 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 UWILD 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 — UWILD Inspection at Gangavaram
Do you provide UWILD at Gangavaram Port?
Yes. Cleanship Marine works Gangavaram Port (INGGV) in Andhra Pradesh, India, covering the deep-draft bulk berths and outer anchorage. Teams mobilise via Visakhapatnam (VTZ) with the full spread.
Can UWILD be done while the vessel works cargo at Gangavaram?
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 Gangavaram and tell you honestly whether the window you have is enough.
Do you need a diving permit from Gangavaram Port Limited?
Yes, and we obtain it. Diving permission from Gangavaram Port Limited, 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 Gangavaram?
Visibility at Gangavaram 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 UWILD on at Gangavaram?
Capesize and Panamax bulk carriers, General cargo ships — the traffic at Gangavaram Port runs to thermal and coking coal, iron ore, bauxite, 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 Gangavaram?
Divers and equipment mobilise via Visakhapatnam (VTZ). 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 Visakhapatnam or Kakinada, one mobilisation is often sized to cover both.
What does UWILD at Gangavaram cost?
It depends on the vessel's dimensions and wetted area, the fouling state found, the coating specification and the working window available at Gangavaram. 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 Gangavaram and you get a scoped price, usually the same working day.
