Cleanship Marine delivers class-approved in-water surveys at Muldwarka Port, Gujarat, with high-definition live video to a surface monitoring station, diver-to-surveyor communications and a full report package for the class file.
Classification societies accept in-water survey in place of drydocking for many vessels and inspection scopes, provided the work is done by an approved diving contractor to a defined procedure with the surveyor able to see the structure in real time. Survey work at an open anchorage lives and dies on the weather window, so class attendance is booked with a realistic standby allowance rather than a single optimistic date.
What it gets you
- Survey requirement satisfied without opening a dry dock or taking the vessel off hire
- Surveyor sees the structure live rather than reviewing a recording after the fact
- Defects located precisely against hull reference marks, not described approximately
- A report package built for the class file, not a video dump
Working conditions at Muldwarka
Muldwarka is an open jetty port on the Saurashtra coast with little natural shelter, so underwater work depends on sea state and is planned outside the south-west monsoon. Arabian Sea water here is comparatively clear, which helps inspection work considerably. Vessels on short coastal cement runs call frequently and, because they spend most of their time in warm coastal water at low speed, accumulate fouling faster between dockings than their trading pattern suggests.

What we do at Muldwarka
- Survey programme agreed in advance with the class society and the surveyor attending at Muldwarka
- Hull plating, welds, sea chests, rudder, propeller and stern gear inspected to the agreed scope
- Live high-definition video to the surface station with two-way diver-to-surveyor communications
- Hull markings and reference points confirmed so the surveyor can locate every feature precisely
- Diving permission and any environmental clearance cleared with Gujarat Maritime Board
- Full report package with video, stills and findings issued for the class file
Planning the window at Muldwarka
The south-west monsoon governs the calendar at Muldwarka 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. Work here is done with the vessel riding to her anchor, so the dive plan is built around sea state and swell rather than a berth slot, and the team stands by for a workable window rather than a scheduled one.
Work is taken at the jetty berth and offshore anchorage, and which of those a vessel ends up at changes the dive plan more than the season does. Teams mobilise via Diu (DIU) or Rajkot (RAJ), 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 Muldwarka
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 Muldwarka than owners budget for.
Vessels here sit at anchor for long periods, and a stationary hull in warm water is the ideal fouling substrate. The heaviest growth we lift at this port is almost always off a vessel that has been waiting rather than working.
Standard scope of work
Included as standard on every in-water class survey attendance, wherever the vessel is. Anything outside it is quoted separately and flagged before mobilisation, never added afterwards.
- Hull structure inspection
- Shell plating, welds, bilge keels and openings inspected with continuous video and commentary, with cleaning of areas as needed for meaningful viewing.
- Rudder and steering gear
- Rudder plating, pintles, bearings and clearances inspected and, where required, measured.
- Propeller and stern arrangement
- Propeller, boss, rope guard and stern tube seal inspected for damage, erosion and leakage.
- Sea chests and openings
- Sea chests, gratings, valves and overboard discharges inspected and recorded.
- Anodes and coating
- Sacrificial anode wastage assessed and coating condition mapped for planning the next dry docking.
How we deliver it at Muldwarka
- 1
Scope and vessel details
Tell us the vessel, her particulars, the coating specification and the window at Muldwarka. 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 Muldwarka
Divers, compressors, brush carts and cameras mobilise via Diu (DIU) or Rajkot (RAJ). Where a vessel is also calling at Pipavav, 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.

Report and handover
A completion report covering in-water class survey 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 — In-Water Survey at Muldwarka
Do you provide in-water class survey at Muldwarka Port?
Yes. Cleanship Marine works Muldwarka Port (INMDK) in Gujarat, India, covering the jetty berth and offshore anchorage. Teams mobilise via Diu (DIU) or Rajkot (RAJ) with the full spread.
Can in-water class survey be done while the vessel works cargo at Muldwarka?
Yes — it is the norm here, because the work is done at anchor rather than at a berth. Barge operations carry on around the dive, with the working side agreed with the master beforehand. The vessel stays on hire throughout, and there is no diversion and no dry dock. We scope against the conditions at Muldwarka and tell you honestly whether the window you have is enough.
Do you need a diving permit from Gujarat Maritime Board?
Yes, and we obtain it. Diving permission from Gujarat Maritime Board, 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 Muldwarka?
Visibility at Muldwarka Port is generally workable outside the monsoon, though cargo dust from lighterage reduces it sharply near an active transfer, 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 in-water class survey on at Muldwarka?
Coastal cement carriers, Handysize bulk carriers, Barges and tugs — the traffic at Muldwarka Port runs to cement and clinker, coal, gypsum, 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 Muldwarka?
Divers and equipment mobilise via Diu (DIU) or Rajkot (RAJ). 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 Pipavav or Porbandar, one mobilisation is often sized to cover both.
What does in-water class survey at Muldwarka cost?
It depends on the vessel's dimensions and wetted area, the fouling state found, the coating specification and the working window available at Muldwarka. 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 Muldwarka and you get a scoped price, usually the same working day.
