Kamsar Underwater Vessel Service

Not every vessel has the same underwater needs. A large bulk carrier, a harbour tug, a river barge and a fishing boat all face different risks and maintenance tasks. Kamsar underwater vessel service is organised by vessel type, so that each owner can see what is relevant and how the service is delivered.

Bulk Carriers

Bauxite carriers are the main visitors. Their needs include class surveys and UWILD, hull cleaning for a large wetted area of roughly 9,000 to 14,000 square metres, propeller polishing, anode replacement and damage inspection after berthing. Services are usually delivered at the anchorage, and focus on keeping the ship available for loading and on meeting class requirements.

Tankers and General Cargo Ships

Tankers and cargo ships calling at Kamsar need similar services but with extra attention to hot work safety and to sea chests and discharges. For tankers, cutting and welding near tanks needs strict gas-free certification, and cold methods are preferred where possible. General cargo ships often need hull cleaning, propeller work and intake clearing.

Tugs and Harbour Craft

Tugs, pilot boats and workboats operate every day, and downtime is costly. Their main underwater needs are propeller and nozzle repair, rope and net clearing, intake cleaning, anode replacement and hull checks. We attend them at their berth, often in a few hours, and schedule regular visits for tugs working in the port.

Barges and River Craft

Barges and river craft work in shallow, silty water, where grounding and impact damage are common. Services include hull inspection after groundings, patching holes and cracks, cleaning and anode checks. Because these vessels are often not under class, we adapt to the owner's needs and provide simple records for insurance.

Fishing and Other Vessels

Fishing boats and other small craft suffer from fouled propellers, damaged rudders and fouled intakes. We provide quick repairs and cleaning, and we are used to working with owners with limited budgets. Where hulls are of wood, fibreglass or aluminium, we choose methods suited to the material.

Choosing the Right Service Level

Each vessel type has a recommended service pattern. For a bulk carrier, an inspection each 6 to 12 months and cleaning of the propeller each 3 to 6 months is common. For a tug, a check and clean every 3 to 4 months is typical. We suggest a plan for each owner after reviewing the vessel's operation and condition.

Tell Us Your Vessel

Send us the vessel type and a short description of the issue, and we will recommend the right service.

Matching Frequency to Vessel Duty

Duty pattern affects maintenance interval. A vessel that works every day in the river needs checks more often than one that waits for weeks between trips. A vessel that spends long periods idle at the berth needs cleaning most often. We ask about the duty pattern and suggest an interval, which can be adjusted after the first few reports. This tailored approach avoids both over-maintenance and neglect.

Documents Needed by Vessel Type

Documents differ by vessel type. For class ships, we need the class details, survey status and hull drawings. For tugs and workboats, a short description and photographs are often enough. For fishing vessels, a basic description and the problem to be solved will do. We keep our requests short, so that owners are not delayed by paperwork, and we adapt reports to the needs of each vessel type and owner.

Getting Started Quickly

The fastest way to start is a short message with the vessel's name, type, location and the problem. We reply with questions, a plan and a price, and the agent can confirm the time. For regular callers, we keep the vessel's details on file, so later requests are even faster.

Frequently Asked Questions (FAQ)

Q1. What is the wetted surface area of a bulk carrier?

Roughly 9,000 to 11,000 square metres for a Supramax and 12,000 to 14,000 for a Panamax.

Q2. How often should a tug be checked and cleaned?

Typically every 3 to 4 months in warm water.

Q3. Can unclassed vessels use the same services?

Yes. We adapt reports and methods to the owner's needs and to insurance requirements.

Q4. How are tankers handled differently?

With strict hot work controls, and cold cutting methods where possible.

Q5. Can aluminium and fibreglass boats be repaired underwater?

Yes, using mechanical patches and underwater-curing compounds rather than welding.
