Commercial Ship Diving Kamsar
Commercial ship diving differs from other diving work because the ship itself is a busy, moving workplace. Cargo operations, crew work, tides, pilots and tugs all affect the Diver. Commercial ship diving in Kamsar is planned around these factors, so that the work does not slow the ship's turnaround, and so that the Diver and crew stay safe.
The Ship as a Work Site
A bulk carrier at Kamsar may be loading thousands of tonnes of bauxite per hour. The ship's draft changes constantly, the berth is busy and engine and pump operations must be controlled. A Diver working on the hull must be protected from suction, discharge, propeller movement and moving ship parts. For this reason, we plan every ship dive with the ship's officers and engineers.
Planning With the Ship
- Date and time agreed with the master, chief officer and agent.
- Draft, trim and list at the time of the dive, noting how they change during loading.
- Isolation of the propeller, thrusters, sea chests and discharges.
- Safe access for the dive boat and, where relevant, a pilot ladder or gangway.
- A permit to work signed by the master and our supervisor.
- Communication by VHF between the ship, the boat and the terminal.
Typical Ship Diving Work
Typical work includes UWILD and class surveys, hull cleaning, propeller polishing, anode replacement, repairs and emergency tasks. Each is scheduled according to the ship's plan. A hull inspection usually takes one to two days, a propeller polish a few hours and an emergency task as long as is required. We keep the ship informed of progress, and stop immediately if the ship needs to move.
Draft and Cargo Considerations
As a ship loads, her draft increases and more of the hull is submerged. This makes more of the side available for inspection, but the water around the ship also changes, with different suction patterns and current. The chief officer should tell us the expected draft at the time of the dive, and any planned ballast operations, as these affect the Diver.
Documentation for Ship Operators
We provide reports in a form that the ship can attach to class files, planned maintenance records and charter documents. These include time-stamped video, photographs, measurements and a summary of findings. Because our teams work in Kamsar regularly, we understand what local agents, surveyors and charterers need, and we adapt reports accordingly.
Safety Culture
A ship dive involves two organisations: the ship and the diving contractor. Clear communication, mutual respect for each other's procedures and a willingness to stop work are essential. We always give the ship a safety briefing, and the master retains authority to stop any operation affecting the ship's safety.
Book Ship Diving
Send the ship's details and the work needed, and we will plan the dive with your officers and agent.
Working With Surveyors, Agents and Charterers
On a commercial ship dive, several parties have an interest. The surveyor wants evidence, the agent wants smooth logistics, the charterer wants to know the hull condition and the owner wants a sound result at a fair price. We coordinate with each, share the plan in advance and provide the same report to all as agreed. This avoids misunderstandings and gives everyone confidence in the outcome.
Contingency Planning
Ship diving can be delayed by weather, ship movements and changes to the cargo plan. We build contingency into every plan, with alternative time slots, backup equipment and flexible team arrangements. If a dive is postponed, we agree a new time with the master and agent, keeping standby charges clear. This flexibility is important in a port where schedules change quickly.
Frequently Asked Questions (FAQ)
Q1. Why does draft matter for a ship dive?
It decides how much of the hull is submerged and changes during loading, affecting what can be inspected and the water flow around the ship.
Q2. Who signs the permit to work?
The master (or authorised officer) and our diving supervisor.
Q3. How long does a ship hull inspection normally take?
One to two working days for a bulk carrier of Supramax or Panamax size.
Q4. Do Divers work during bauxite loading?
Sometimes, with the terminal's consent and with a plan that covers draft changes and safety distances.
Q5. What isolation is needed?
Propeller and thrusters locked, sea chests and discharges closed or isolated, and pumps stopped near the work area.
