Marine Open Link Chain

Marine Open Link Anchor Chain

Introduction:

Marine open link anchor chain is also called studless link anchor chain. It compared with stud link anchor chain, the studless link anchor chain feature less weight and less strength. The marine open link anchor chain is not commonly used for ships to connect anchor.

Anchor Chain Inspection:

Regular inspections of the anchor chain are essential for ensuring its safety and reliability. Here are some key steps to follow when inspecting an anchor chain:
Visual inspection: Begin by visually inspecting the entire length of the anchor chain for signs of wear, damage, or corrosion. Check each link, shackle, and connection for any signs of cracking, bending, or deformation.
Ultrasonic testing: Ultrasonic testing can be used to detect internal flaws or defects in the anchor chain. This can be done by using a special ultrasonic probe that is passed over the surface of the chain, which sends sound waves through the metal to detect any internal flaws.
Magnetic particle testing: Magnetic particle testing can be used to detect surface cracks or defects in the anchor chain. This involves applying a magnetic field to the chain and then dusting it with iron particles. Any surface cracks or defects will be highlighted by the iron particles.
Tension testing: Tension testing can be used to check the strength and integrity of the anchor chain. This involves applying a known load to the chain and measuring the resulting elongation or deformation. The test results can be used to determine the chain's load capacity and to identify any weak or damaged links.
Measurement: Measure the diameter of the links to ensure they are still within the manufacturer's specifications. Also, check the length of the chain to ensure it is still long enough for the vessel's needs.
Record keeping: Record the results of the inspection and any repairs or maintenance that were performed. This will help to ensure that the chain is properly maintained and that any issues are addressed in a timely manner.
By following these steps, you can help ensure the safe and reliable operation of your anchor chain. It's also important to refer to the manufacturer's guidelines for specific inspection recommendations based on the type and size of your anchor chain.
