Introduction to Marine Mooring Bollards-Part 1

Marine mooring bollards are essential equipment on port docks and ship decks. As a core component of the ship mooring system, bollards play a critical role in securing vessels and resisting the impact of wind, waves, and currents. These sturdy metal components safely moor ships at berths through mooring lines, ensuring the safe and orderly operation of port activities and vessel docking.

Basic Structure and Manufacturing Materials

A typical mooring bollard consists of three main parts: the column that bears the pulling force, the cap that guides and secures the ropes, and the base that ensures overall stability. The bollard cap comes in various designs, including cross-shaped and horn-shaped types, with different shapes meeting diverse operational needs.

In terms of material selection, high-quality carbon steel is the most commonly used material due to its excellent strength and weldability. For corrosive environments, stainless steel is preferred. Additionally, cast steel is often used for manufacturing large bollards with complex structures and high load-bearing requirements.

To ensure long-term durability, bollard surfaces are typically treated with anti-corrosion methods. Hot-dip galvanizing is the most common treatment, forming a thick protective layer that effectively resists seawater corrosion. Depending on specific needs, anti-corrosion coatings are sometimes applied as a supplement.
