Marine Bollard: Key Equipment for Safety and Stability

Marine bollard are indispensable and crucial equipment in the mooring and anchoring operations of ships. They are mainly used to secure the ships and ensure their stability and safety during the mooring period. Whether at port terminals, offshore platforms, or on ocean-going vessels, bollard play a significant role.

Marine bollard are usually installed on the ship’s deck, dock berths or floating platforms, and the working environment is complex and changeable. These devices need to withstand harsh natural conditions, such as salt fog corrosion, high humidity, temperature fluctuations, and frequent mechanical stress. Moreover, the grappling hooks also need to work under dynamic conditions, such as the swaying of the ship in waves and changes in tension. Therefore, the design of marine grappling hooks must possess high strength, corrosion resistance and good stability.

Bollard is a fixed or movable pile structure, usually consisting of a pile body and a fixed base.  The pile body is the part that directly bears the tension, and its design needs to take into account its tensile strength and bending resistance; the fixed base is used to firmly install the pile body on the deck or the dock. Modern pile-mounted structures may also be equipped with anti-slip devices, buffering devices or automatic adjustment systems to enhance the safety and convenience of operation.

In practical applications, marine bollard need to be used in conjunction with mooring ropes. One end of the rope is fixed to the bollard, while the other end is connected to the dock or other fixed facilities. By properly arranging multiple ropes, the stability of the vessel can be ensured under different wind directions and water flow conditions.

The selection of materials for ship Bollard is of vital importance as it directly affects their service life and safety. Here are the common stainless steel materials and their characteristics: Stainless steel has excellent corrosion resistance and tensile strength, making it suitable for use in high-salt spray and high-humidity environments. However, due to its high cost, it is usually used in situations where high corrosion resistance is required.

Marine bollard are the core equipment for ensuring the safe berthing of ships. Their performance and material directly affect the stability of the vessel and the safety of personnel. When selecting and using bollard, factors such as the usage environment, material characteristics, and economic cost need to be comprehensively considered to ensure the efficient operation and long-term reliability of the equipment.
