Underwater Marine Repairs Kamsar Port
Marine repair covers both ships and the structures they use. At a busy bauxite port like Kamsar, jetties, mooring dolphins, fenders and loading structures are exposed to heavy ships and strong river currents. Underwater marine repairs in Kamsar Port address damage to both vessels and port structures, with a single team and consistent reporting.
Ships and Structures Together
When a bulk carrier touches a berth, both the ship and the structure may suffer damage. A Diver can inspect the ship's hull and the jetty piles, fenders and dolphins in one visit, giving a joint record for the owner, the terminal and the insurers. This avoids disputes about what was damaged and by whom, because the evidence is complete and neutral.
Repairs on Port Structures
- Inspection and repair of steel and concrete jetty piles, including corrosion and impact damage.
- Fitting protective wraps or jackets to damaged piles.
- Replacement or repair of fender attachments and chains below the waterline.
- Repair and inspection of mooring dolphins and bollard foundations.
- Clearing debris, ropes and obstructions from berths and approaches.
Repairs on Ships
On ships, typical repairs include hull plating, sea chests, anodes, propellers and rudder fittings, as described elsewhere on this website. Because the same team can attend both the ship and the berth, the work can be coordinated with the terminal and with the ship's schedule, which saves time.
Inspection Before Repair
Every repair starts with an inspection. We measure corrosion on piles with ultrasonic gauges, record scour around foundations, photograph cracks and damaged coating and plot the results on a sketch. The terminal engineer or the ship's superintendent can then decide on the scope and priority. A well-documented inspection also supports a maintenance plan for the structure.
Materials and Methods
Repairs use marine-grade steel, underwater-curing epoxy grouts, wraps and mechanical clamps for piles, and welding where appropriate. For structures in tidal water, the repair material must cure properly in wet conditions and withstand abrasion from silt and floating debris. We specify materials that are tested for such use.
Safety Near Active Berths
Working near a berth with ships and conveyors needs careful coordination. We agree a permit to work with the terminal, mark the work area, inform the control room and keep a standby diver. When ships are berthing or sailing, the work stops. Our aim is always to avoid interference with cargo operations.

Planning Repairs Around Berth Occupancy
A busy berth has little free time. We work with the terminal to find windows between ships, such as the hours between a sailing and the next arrival. Short, well-prepared repairs fit into such windows. For longer work, we divide the job into stages that can be completed in separate windows, leaving the berth safe and usable at the end of each. The terminal receives a simple daily plan and report.
Inspection Records for Structures
Records are important for structures. We keep an inspection record for each pile, fender and dolphin we visit, with date, condition rating, photographs and thickness readings. When the same item is inspected again, the new record is compared with the old, and the rate of change is calculated. This helps the terminal to plan repairs before failure and to justify budgets. It also provides a reference in case of damage by a ship, so that the new damage can be distinguished from older wear. Terminals receive the records in electronic form with a summary sheet. Over several years, this record becomes a valuable asset for maintenance planning and for audits by owners or lenders.
Frequently Asked Questions (FAQ)
Q1. Which port structures can be repaired underwater?
Jetty piles, fender attachments, mooring dolphins, bollard foundations and approaches.
Q2. How is pile corrosion measured?
With ultrasonic gauges on cleaned surfaces, to a resolution of about 0.1 mm.
Q3. Can ship and berth damage be recorded together?
Yes. A single Diver team can inspect both and issue a joint record.
Q4. How long does a pile inspection take?
About 30 to 60 minutes per pile for cleaning, inspection and photographs, depending on size and visibility.
Q5. Do repairs interrupt loading?
Not normally, if planned with the terminal and carried out in quiet periods.
