Cleanship Marine delivers class-approved in-water surveys at Hazira 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. Low visibility and short slack windows make this a demanding survey port. Scope, lighting and the surveyor's acceptance criteria are agreed up front, and where the conditions will not support the scope we say so before the attendance is booked.
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 Hazira
Hazira works the outer part of the Gulf of Khambhat, so the tidal stream is strong and the water silty, though conditions are less extreme than at the head of the gulf. Dive windows are still planned to slack water, and visibility is low enough that hull work is executed by feel with video kept as the record. The terminals run tight windows, so scope, crew size and tooling are agreed and staged before anyone enters the water.

What we do at Hazira
- Survey programme agreed in advance with the class society and the surveyor attending at Hazira
- 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 Hazira
The south-west monsoon governs the calendar at Hazira 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 container terminal, steel raw material berths and LNG jetty, and which of those a vessel ends up at changes the dive plan more than the season does. Teams mobilise via Surat (STV) or Vadodara (BDQ), 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 Hazira
Liquid and gas tonnage here spends long stretches at the terminal or waiting for a slot, so growth tends to be even and well established across the hull rather than patchy — heavier than the trading pattern suggests, and further along than a speed report alone would indicate.
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.
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 Hazira
- 1
Scope and vessel details
Tell us the vessel, her particulars, the coating specification and the window at Hazira. 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 Hazira
Divers, compressors, brush carts and cameras mobilise via Surat (STV) or Vadodara (BDQ). Where a vessel is also calling at Magdalla, 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 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 Hazira
Do you provide in-water class survey at Hazira Port?
Yes. Cleanship Marine works Hazira Port (INHZR) in Gujarat, India, covering the container terminal, steel raw material berths and LNG jetty. Teams mobilise via Surat (STV) or Vadodara (BDQ) with the full spread.
Can in-water class survey be done while the vessel works cargo at Hazira?
Usually yes, but the tide sets the schedule rather than the cargo plan. The practical question is how many slack windows fall inside the vessel's stay, not what the holds are doing. The vessel stays on hire throughout, and there is no diversion and no dry dock. We scope against the conditions at Hazira 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 Hazira?
Visibility at Hazira 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.
Which vessels do you carry out in-water class survey on at Hazira?
Container ships, Bulk carriers, LNG carriers and Car carriers — the traffic at Hazira Port runs to containers, steel and steel raw materials, lng, 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 Hazira?
Divers and equipment mobilise via Surat (STV) or Vadodara (BDQ). 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 Magdalla or Dahej, one mobilisation is often sized to cover both.
What does in-water class survey at Hazira cost?
It depends on the vessel's dimensions and wetted area, the fouling state found, the coating specification and the working window available at Hazira. 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 Hazira and you get a scoped price, usually the same working day.
