Underwater Ship Cutting Services Kamsar
Cutting is often the first step of a repair, and sometimes it is the whole job. A bent plate must be removed before a patch can be fitted, a wire must be cut from a propeller, or a damaged fitting must come off. Underwater ship cutting services in Kamsar cover all these tasks, using methods chosen for the material, the safety conditions and the class requirements.
Typical Cutting Jobs
- Removing damaged or distorted plate before patching or repair.
- Cutting away wires, ropes, nets and plastic from propellers, shafts and rudders.
- Cutting anchor chain, shackles or parts of lost gear when needed.
- Removing obstructions fouling the hull or sea chest.
- Cutting out corroded or broken fittings, pad eyes and brackets.
- Cutting steel debris that blocks the berth or approach.
Choosing the Method
For steel plate, oxy-arc or exothermic cutting is most effective. For cables, wire ropes and chains, hydraulic cutters or shears are often quicker and safer. Where hot work is not allowed, for example near fuel tanks or in sensitive areas, diamond wire or mechanical saws are used. The Diver and supervisor select the method after inspecting the item and assessing the hazards.
Safe Cutting on Hulls
Before cutting on the hull, the ship confirms that the spaces behind the plate are safe and that no flammable liquid or gas is present. The cut line is marked on the plate, and the Diver cuts from the outside, working to avoid damaging adjacent structure. For openings in the shell, the Diver may leave small tabs to keep the plate in place until it can be lifted and removed safely.
Cutting Lines From Propellers
A rope or net around the propeller is a common reason for calling a Diver. The cutting must avoid damaging the blade, shaft or seal. We use sharp, specialised cutters, working slowly to unwind and cut away the material in sections. Everything removed is brought to the surface and disposed of ashore. Photographs before and after record the condition.
Debris and Wreckage
Steel pieces, tyres, drums and other junk can end up beneath ships or at berths in a busy port. We can cut and remove such items so that ships can berth and sail safely. Large pieces are cut into sections that can be lifted by the ship's crane, a workboat or a shore crane.
Records
We record what was cut, where, and by which method. If class or an insurer needs it, we provide photographs and video of the area before and after. When the cut is part of a repair, the repair report refers to the cutting record.
Request a Cutting Service
Send details and photographs of the item to be cut, and we will propose a method and time.
Disposal and Environmental Care
Items removed from the water must be handled responsibly. Rope, net and plastic are taken ashore and disposed of in the proper waste stream. Steel pieces are lifted and either returned to the ship, handed to the terminal or disposed of as scrap, as agreed. We avoid releasing oil, paint chips or other pollutants during cutting, and we keep the area clean so that the port remains free of new hazards after the job.
Planning the Lift After Cutting
When a piece of steel is cut free, its removal must be planned. We agree on how it will be lifted, who will handle the crane or workboat and where the piece will be placed. We rig slings before the final cut, so the piece does not fall or drift. This planning prevents injuries, protects the ship and makes the job faster.
Frequently Asked Questions (FAQ)
Q1. Which tool cuts steel plate underwater?
Oxy-arc or exothermic cutting for plate, with mechanical tools used where hot work is restricted.
Q2. How is a wire rope cut underwater?
With hydraulic cutters or shears, which can cut wire ropes and chains without heat.
Q3. How long does it take to clear a propeller of rope?
Usually 1 to 4 hours, depending on how tightly wrapped the line is.
Q4. Is a hot work permit needed?
Yes, for any thermal cutting on the hull, issued by the ship after confirming adjacent spaces are safe.
Q5. Can large debris be removed from a berth?
Yes. We cut it into sections and lift it with the available crane or workboat.
