How to Choose The Right Marine Bollard - Part 2
4. Dimensions and Installation - Diameter ≥ 6 x 6 of the rope diameter (to ensure the bending radius of the rope). - Anchoring requirements: High-strength anchor bolts + sufficient floor area, and the load needs to be transferred to the load-bearing structure of the wharf. - Fatal point: The loca......

How to Choose The Right Marine Bollard - Part 1
1. Core Elements Mooring load - Calculation basis: Ship tonnage, wind, wave and current intensity, mooring Angle (the smaller the Angle, the greater the load). - Safety Requirements: The safe working load (SWL) of the cable pile should be no less than the expected maximum load x 1.5 (refer to the......

Benefits of Roller Fairleads in Marine Environments
1. Reduced Rope Wear The harsh marine environment can be especially harmful to the ropes and cables used on ships and offshore structures. Saltwater exposure, constant movement due to waves and currents, and friction from repeated use can all cause fraying, kinking, and, eventually, rope failure. T......

Introduction to Ship Mooring Cable
1. Structural Classification Single-strand rope (1×7/19) : High rigidity, used for small mooring. Multi-strand rope (6×7/19/37) : The most commonly used, balancing strength and flexibility, suitable for dragging and hoisting. Composite rope (18×7/34×7) : Strong fatigue resistance, used in deep-wa......
