A number of movable "necklaces" are made of fibre cotton rope. They are tailored to the drum and can be tightened on the drum. This can be flexible for each port of high-quality marine cable because of the different angle of the cable may be placed by the cable roller wear. It is found that the cotton necklace can greatly reduce the wear between the high quality marine cable and the guide roller.
Check all guide roller before arrival to ensure smooth surface and looping, and take all possible measures to reduce wear and tear. Take a certain ship as an example: there are 92 guide cable rollers in the whole ship. The supervisors should be arranged to disassemble and refuel regularly to ensure the loops. Before each arrival, the outer surface of the ship should be repaired with paint to ensure its smooth surface. In order to avoid the contact between the polymer polyethylene cable and the rigid roller base of the guide cable and the outer plate of the hull, an old cable is added across the outlet of the guide cable hole. The actual test shows that the effect is better.
