A mooring bollard functions as a vital fixture in maritime transportation and shipping, employed to safely fasten ships and boats to a dock or quay. Serving as a secure anchor point, mooring bollards play a crucial role in the mooring process. Mooring lines, comprising ropes or cables, are attached to the vessel and secured to these bollards.
This setup ensures that the ship remains firmly in place while berthed, preventing unwanted movement and ensuring stability during docking operations. Mooring bollards are fixed on the deck or pier, preventing unintended movement, facilitating efficient loading and unloading operations, and their design varies to accommodate different mooring requirements.
Crafting mooring bollards involves either metal casting or welding, and their structural design is crucial to withstand the forces applied by mooring lines. Various mooring bollard types and styles are available, each customized for specific applications and vessel dimensions.
Marine mooring bollards that are appropriately designed, installed, and properly maintained contributes to safe, efficient, and dependable vessel mooring and to mitigate the risks associated with improper use or not utilizing mooring bollards such as the following:
Confusion and Danger - An unclear mooring area without proper equipment can create confusion and pose danger. Unused ropes and equipment may lead to hazards, especially in areas with a higher degree of risk
Corrosion and Maintenance Issues: Mooring bollards, when not used, are exposed to seawater, increasing the risk of corrosion. Neglecting their use may result in maintenance issues, affecting the service life of the bollards.
Overloading Risks: Deviating from proper mooring practices, such as overloading bollards with multiple mooring lines, can lead to specific risks. Overloading may compromise the structural integrity of the bollards, posing a threat to safety.
Fatal Accidents: Mooring accidents, including fatal incidents, have been recorded due to poor mooring practices.
Snap Back Accidents: One of the significant dangers in mooring operations is the risk of snap-back accidents, where the failure of ropes or wires can lead to sudden and hazardous movements.
The mentioned risks emphasize the importance of safety considerations. Utilizing mooring bollards will definitely provide numerous benefits in maritime operations, here are some:
Secure Docking: Mooring bollards provide secure points for ships and boats to dock, preventing them from drifting or moving accidentally during loading, unloading, or while stationary at a quay or dock.
Preventing Accidents: The use of mooring bollards helps prevent accidents by ensuring vessels are securely anchored. This is essential in busy ports and harbors where precise control over a vessel's position is crucial for safety
Stability and Control: Bollards act as fixed points to which mooring lines or ropes are attached, providing stability and control over the vessel's movement. This is especially important in adverse weather conditions or strong currents.
Structural Integrity: Mooring bollards are designed to engage with the bottom quickly, generating a grasping force that enhances their structural integrity. This ensures their effectiveness in holding vessels securely.
There are standards established for utilizing mooring bollards in maritime applications. Compliance with these standards is crucial to ensure the safety, efficiency, and reliability of mooring systems. ISO 13797:2020 is a standard in the field of ships and marine technology. It specifies the types, nominal sizes, dimensions, materials, and construction requirements for bollards used in mooring and towing operations on sea-going vessels.
The document outlines the manufacturing and marking requirements for these bollards, providing a comprehensive guide for their design and use in the maritime industry. The standard aims to ensure consistency and safety in the construction and implementation of bollards.
Proper installation of mooring bollards is essential for ensuring a prolonged and trouble-free lifespan. Accurate installation of anchor bolts using a bolted template formwork is crucial. After the grout attains maximum strength, anchor bolts can be securely tightened to the designed preload. Adhesives are frequently applied around exposed threads to simplify future removal. Whenever feasible, embedding the bollard in concrete offers more advantages than surface mounting.
Over time, the mechanical efficiency of bollards can decline. It is imperative to conduct durability tests and consistently inspect them to ensure optimal functionality and identify any maintenance requirements.
Thoughtful considerations in following standards for mooring bollards include:
Proper Training: Users should receive adequate training in the safe use of mooring bollards to minimize risks.
Choosing the Right Bollards: Consideration of boat length and reliable suppliers is advised when selecting mooring bollards.
Variety of Design Profiles: Bollards are available in a range of design profiles, sizes, and capacities to suit different mooring system applications.
Compliance with Industry Standards: Ensure that mooring bollards comply with relevant industry standards and regulations
