CCTV inspections Kamsar Port
Some underwater areas are small, dark or awkward. A sea chest, a thruster tunnel, the space between the rudder and the stern frame and the gap under a berth fender are examples. CCTV inspections in Kamsar Port use compact cameras and lighting to see inside these spaces without removing the ship from service.
Where CCTV Is the Best Tool
A Diver cannot always enter or see into a confined opening. A small camera on a pole or a short cable can. CCTV inspection is particularly suitable for sea chests and grating condition, thruster tunnels, bow and stern thruster blades, the clearance around the rudder stock and the condition of anodes inside recesses. For port users, the same technology can inspect pile condition and mooring points near the working area.
Typical Inspection Targets
- Sea chest gratings, to check for blockage by growth, bags, rope or debris.
- Bow thruster and stern thruster tunnels, for blade damage and corrosion.
- Rudder, pintle and stock gaps, for wear or fouling.
- Propeller hub and cone, for cracks, leaks and corrosion.
- Overboard discharge openings and strainers.
Why Early Detection Matters
A blocked sea chest can cause overheating of the main engine or auxiliary machinery, which may lead to engine room alarms or a shutdown. A damaged thruster blade can fail when most needed during berthing. CCTV inspection finds these problems while they are small, allowing the ship's engineers to plan the repair rather than react to a breakdown at a critical moment.
Combining CCTV With Cleaning
Often the inspection finds the cause of the problem, and the Diver can fix it in the same dive. Growth on a sea chest grating can be removed, a rope around a thruster can be cut away, and loose debris can be cleared. We record video before and after, so the owner sees the effect of the work.
Safety Around Openings
Working near a sea chest or thruster tunnel carries hazards, because suction or rotation can harm a Diver. Our procedures require positive isolation of the equipment, lock-out confirmation from the engine room and a written permit before the Diver or camera is placed near an opening. The master or chief engineer signs the isolation before the dive begins.
Arrange a CCTV Inspection
Tell us the area of concern, and we will arrange the camera, lighting and isolation procedure.
Planning a CCTV Inspection With the Engine Room
A CCTV inspection of sea chests and tunnels needs the engine room's cooperation. The chief engineer should state which pumps and valves are connected, confirm lock-out in writing and provide drawings. We agree a signal for stopping work and keep a radio link open. After the inspection, we share the video with the engineer, who can use it to plan maintenance. This planning step takes only a few minutes and prevents the main hazards of confined inspections.
Types of Camera Used
Different spaces call for different cameras. A diver-worn camera suits open hull areas. A hand-held camera on a short pole reaches into rudder gaps and sea chests. A small tethered camera or crawler can enter pipes and tunnels where a person cannot go. Each has its own lighting, and we choose the kit after reviewing the drawings and the task. Cameras are fitted with wide-angle lenses to give a clear picture in tight spaces, and with scale markers to measure defects. Having the right tool avoids wasted time and unclear recordings. After inspection, the footage is reviewed by the supervisor before the team leaves the site.
Frequently Asked Questions (FAQ)
Q1. Which underwater spaces are best inspected by CCTV?
Sea chests, thruster tunnels, rudder gaps, propeller hubs and discharge openings.
Q2. What size can an inspection camera be?
Compact cameras can be only a few centimetres across, allowing entry into openings that a Diver cannot reach.
Q3. How long does a CCTV check of a sea chest take?
Usually 30 to 60 minutes per sea chest, including isolation and recording.
Q4. Is isolation always required?
Yes. Machinery with suction or rotation must be stopped and locked out before any work.
Q5. Can CCTV find the cause of engine cooling problems?
Often yes. Blocked sea chest gratings and strainers are a common cause and are easy to see on camera.
