Cleanship Marine delivers class-approved in-water surveys at Ratnagiri Port, Maharashtra, 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. This is one of the better ports on the coverage list for in-water survey work: clarity supports the wide shots and the close detail a surveyor needs, and the record that comes out of it stands up in the class file.
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 Ratnagiri
Ratnagiri works a sheltered bay on the Konkan coast with reasonably clear water outside the monsoon, which suits inspection and survey work as well as cleaning. The south-west monsoon between June and September closes most of the season. Depth in the inner harbour is limited, so deep-sea tonnage is worked at the anchorage and the swell reaching it sets the practical window.

Planning the window at Ratnagiri
The south-west monsoon governs the calendar at Ratnagiri 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. Water clarity here is good by regional standards, so the operation can be properly documented on video as it happens — an advantage that turns a cleaning job into usable condition evidence at no extra mobilisation cost.
Work is taken at the inner harbour berths, anchorage and Jaigad terminal nearby, and which of those a vessel ends up at changes the dive plan more than the season does. Teams mobilise via Ratnagiri or Mumbai (BOM), 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 Ratnagiri
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 Ratnagiri than owners budget for.
Clearer water means the fouling state can be assessed properly before any tooling is selected, and the assessment can be shown to you rather than described.
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 Ratnagiri
- 1
Scope and vessel details
Tell us the vessel, her particulars, the coating specification and the window at Ratnagiri. 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 Maharashtra 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 Ratnagiri
Divers, compressors, brush carts and cameras mobilise via Ratnagiri or Mumbai (BOM). Where a vessel is also calling at Mormugao, 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 Ratnagiri
Do you provide in-water class survey at Ratnagiri Port?
Yes. Cleanship Marine works Ratnagiri Port (INRTC) in Maharashtra, India, covering the inner harbour berths, anchorage and Jaigad terminal nearby. Teams mobilise via Ratnagiri or Mumbai (BOM) with the full spread.
Can in-water class survey be done while the vessel works cargo at Ratnagiri?
Yes. Conditions here are good enough that the dive runs alongside cargo operations without either holding the other up, and the work is documented on video as it goes. The vessel stays on hire throughout, and there is no diversion and no dry dock. We scope against the conditions at Ratnagiri and tell you honestly whether the window you have is enough.
Do you need a diving permit from Maharashtra Maritime Board?
Yes, and we obtain it. Diving permission from Maharashtra 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 Ratnagiri?
Visibility at Ratnagiri Port is good by regional standards and usually adequate for video work, 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 Ratnagiri?
Handysize bulk carriers, Coastal tonnage, Fishing and support craft — the traffic at Ratnagiri Port runs to coal, bauxite and general cargo, 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 Ratnagiri?
Divers and equipment mobilise via Ratnagiri or Mumbai (BOM). 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 Mormugao or Mumbai, one mobilisation is often sized to cover both.
What does in-water class survey at Ratnagiri cost?
It depends on the vessel's dimensions and wetted area, the fouling state found, the coating specification and the working window available at Ratnagiri. 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 Ratnagiri and you get a scoped price, usually the same working day.
