Design and Structure

Design essentials:

Consideration of Ship Types and Berthing Forces:Ships of different types and tonnages generate different magnitudes of mooring forces when berthing. For example, large container ships and bulk carriers produce relatively large mooring forces during berthing, while the mooring forces of small yachts and fishing boats are comparatively smaller. Therefore, when designing T - shaped mooring bollards, it is necessary to accurately understand the types of ships served by the wharf and the distribution of their tonnages. Through mechanical calculations and simulation analyses, the dimensions, shapes, and material selections of the mooring bollards should be reasonably determined to ensure that the bollards can withstand the mooring forces of the corresponding ships, thus guaranteeing the safety and stability of ship berthing.

Adaptation to environmental conditions:T - shaped mooring bollards are usually installed in coastal or inland water environments and are affected by various natural environmental factors. During the design process, the impact of these environmental factors on the mooring bollards must be fully considered.

For instance, in a marine environment, mooring bollards are subject to seawater corrosion. Therefore, materials with good corrosion resistance, such as stainless steel or steel with special anti - corrosion treatment, should be selected. Additionally, protective measures like hot - dip galvanizing and spraying anti - corrosion coatings should be applied to the surface of the mooring bollards to extend their service life.

Meanwhile, dynamic factors such as strong winds, huge waves, and water currents also exert significant forces on the mooring bollards. During the design, methods such as wind tunnel tests and wave flume tests are required to accurately evaluate the impact degree of these dynamic factors on the mooring bollards. Corresponding structural strengthening measures, such as increasing the wall thickness of the mooring bollards and reinforcing the support structure, should be taken to ensure that the mooring bollards can still maintain a stable and reliable working state under harsh natural environmental conditions.

structure composition:

Mooring Head:The mooring head is a structural component horizontally installed at the top of the T - shaped mooring bollard. It is usually welded from steel plates, featuring large dimensions and a thick and wide cross - section. This design ensures that it has sufficient strength and stiffness when bearing the mooring forces of ships.

The upper surface of the mooring head is typically designed with multiple mooring holes or bitts. The distribution and dimensions of these mooring holes or bitts are designed according to actual usage requirements, enabling the ship's mooring ropes to be easily and quickly fastened to the mooring head.

When the mooring bollard bears the mooring forces of the ship, as the directly - loaded component, the mooring head transfers the tension and various complex forces transmitted by the mooring ropes to the supporting column below through its own structure. These forces are then further transmitted to the foundation structure, ultimately achieving the stable mooring of the ship.

Support Column:The support column is a vertically - arranged structural component at the bottom of the T - shaped mooring bollard. It is a crucial part connecting the mooring head and the foundation structure. Usually made of steel pipes or sections, it has high strength and stability.

The diameter or cross - sectional dimensions of the support column are rationally selected according to the designed load - bearing capacity of the mooring bollard and actual usage requirements. This ensures that it will not deform, break, or suffer other forms of damage when bearing the huge pulling force and impact transmitted from the mooring head.

At the bottom of the support column, an enlarged base plate or flange is usually installed. The support column is firmly connected to the foundation structure through anchor bolts or welding, guaranteeing the stability and reliability of the mooring bollard during operation.

When a ship is moored at the dock, the support column not only bears the vertically downward pulling force transmitted from the mooring head but also withstands horizontal forces caused by factors such as ship swaying, wind, and water flow, as well as various complex torsional forces. Therefore, when designing the support column, it is necessary to comprehensively consider various loading conditions. Through reasonable structural design and mechanical calculations, ensure that the support column has sufficient strength, stiffness, and stability to reliably transfer all the forces borne by the mooring bollard to the foundation structure, thus ensuring the safe mooring of the ship.

Reinforcement Structure:To further enhance the overall strength, stiffness, and stability of the T - shaped mooring bollard, reinforcement structural components are typically incorporated into the bollard's structural design. These components mainly include gusset plates, stiffeners, and supporting angles. They are firmly connected to the main structural components such as the mooring head and support column through welding or bolted connections, forming an integrated reinforcement structure system.

Gusset plates, a common type of reinforcement component, are usually made of steel plates. They are installed at the connection points between the mooring head and support column, as well as inside the support column. By increasing the structural thickness and cross - sectional area at these locations, the strength and stiffness of the mooring bollard at these critical points are enhanced. This effectively prevents deformation, cracking, and other damage at these connection points and within the support column when the bollard bears the mooring forces of ships and various external forces.

Stiffeners, another commonly used reinforcement component, are usually made of angles or channels. They are placed on the surfaces of the mooring head and support column, distributed along the length or width of the structural components. By increasing the local stiffness and stability of the surfaces of the structural components, the bollard's ability to resist external forces at these locations is improved. This effectively prevents local deformation, buckling, and other damage on these surface areas when the bollard bears the mooring forces of ships and various external forces.

Supporting angles, a structural component for enhancing the overall stability of the mooring bollard, are usually made of angles. They are installed at the connection between the bottom of the mooring bollard and the foundation structure, as well as on the sides of the bollard. By connecting with the foundation structure or other support structural components, a stable support system is formed, enhancing the overall stability of the mooring bollard during operation. This effectively prevents the bollard from tipping over or slipping when bearing the mooring forces of ships and various external forces.

These reinforcement structural components play a vital role in the structure of the T - shaped mooring bollard. By working in tandem with the main structural components such as the mooring head and support column, they jointly bear the mooring forces of ships and various external forces, effectively improving the overall strength, stiffness, and stability of the mooring bollard. This ensures that the mooring bollard can operate safely and reliably during actual use, providing a strong guarantee for the safe mooring of ships.

Installation and Maintenance:

1. Installation

• For embedded installation, during the construction of the wharf foundation, installation holes should be reserved according to the design requirements. After precisely positioning the embedded parts at the bottom of the mooring bollard, concrete is poured for fixation.

• As for welded installation, after the construction of the wharf structure is completed, the bottom of the mooring bollard is connected to the pre - embedded steel plate of the wharf by welding. The welding quality must comply with relevant standards.

• During the installation process, professional measuring instruments are used to ensure the verticality and levelness of the mooring bollard, with the deviation controlled within a minimal range.

2. Maintenance

• Regularly inspect the surface of the mooring bollard for any coating damage, rust, deformation, etc. If there is minor coating damage, repair it in a timely manner. In case of rust, remove the rust by grinding and then repaint.

• Regularly check whether the connection between the mooring bollard and the foundation is loose. If there are any problems, tighten it promptly.
