Underwater Hull Survey Kamsar

A hull survey differs from a quick look at the hull: it is a planned, systematic examination, with a defined scope, a recorded method and a written result. An underwater hull survey in Kamsar gives owners of Bauxite Carriers and other vessels a documented picture of their ship's underwater condition, without the time and cost of dry-docking. It can serve class, insurers, charterers or a buyer in a sale and purchase transaction.

Planning a Structured Survey

Every survey starts with a plan. We divide the underwater hull into zones: stem and bow, port and starboard vertical sides, flat bottom, bilge keels, stern and the rudder and propeller area. For each zone we agree the method, the inspection level and the report format. The plan is based on the ship's lines plan, the class requirements and any previous survey report, so that the new survey can be compared directly with earlier results.

The Survey Method

The Diver follows a fixed pattern along each zone, normally from stern to bow, in overlapping runs.

A CCTV camera with a scale bar records each run, and the supervisor logs the time and position.

Defects are marked, photographed and measured, with size and depth noted.

Thickness Measurement is taken on cleaned steel at pre-agreed points.

Appurtenances such as sea chests, thruster openings and anodes are checked in detail.

What the Survey Report Shows

The report presents the ship's hull as a map. For each zone it states the coating condition, the level of fouling, the number and position of defects and the thickness results. Photographs are tied to hull positions, and the video is indexed so that the reader can find a specific frame. The result is a document that an owner, an insurer or a class surveyor can use without having been present at the dive.

Surveys for Sale and Purchase and Charter

A hull survey is also a commercial tool. A buyer of a second-hand ship wants to know the true condition of the underwater hull before agreeing a price. A charterer wants to know that the ship will not suffer speed loss from heavy fouling. A neutral, well-documented survey by an independent diving contractor provides this evidence. We keep the findings factual and avoid opinion about value, leaving that to the parties and their advisers.

Working at Kamsar

Surveys are carried out at the anchorage area or alongside, depending on the ship's schedule. The tidal estuary affects visibility and current, so we plan around slack water and use lighting and local cleaning to produce a clear record. Typical survey time for a Supramax or Panamax is one to two working days, with a preliminary report on the day of completion.

Request a Hull Survey

Send the ship's name, class and desired scope, and we will return a survey plan and a fixed-scope quotation.

Survey Levels and Scope Options

Not every ship needs the same survey. A basic condition survey records coating and fouling by CCTV and photographs. A detailed survey adds close-up inspection of defects and Thickness Measurement at selected points. A class survey follows the society's checklist and adds the surveyor's attendance. We recommend the level that matches the purpose: for a charter handover a basic survey may be enough, while a class UWILD needs the full scope. We state the level clearly in the quotation.

Linking Results to Planned Maintenance

A hull survey is most useful when its results feed into the ship's planned maintenance system. We list each finding with a suggested action and a priority, such as monitor, clean, touch up or repair at next dry-dock, so the superintendent can enter them directly.

Frequently Asked Questions (FAQ)

Q1. What is the difference between a hull inspection and a hull survey?

A survey is formal, with a defined scope, method and report. An inspection can be a shorter, targeted check of one area.

Q2. How many hull zones are normally surveyed?

Typically 6 to 8 zones: stem, port side, starboard side, flat bottom, bilge keels, stern, rudder and propeller area.

Q3. How long does a full hull survey take?

Planning figure: 1 to 2 working days for a Supramax or Panamax bauxite carrier.

Q4. How long is the survey report valid?

The report records condition on the survey date. Class societies and buyers usually look for reports no older than 6 to 12 months.

Q5. Can a hull survey be used for sale and purchase?

Yes. Buyers frequently request an independent underwater survey before delivery, to document hull condition.
