Material and Manufacturing:

Material Advantages:

 

High-strength and pressure-resistant: Cast steel is selected as the core material. This material has extremely high mechanical strength and toughness, which can easily withstand the 150-ton tension during the mooring process. It can also resist the impact force generated by large ships on the mooring lines due to wind and waves, avoiding structural deformation or fracture. Some products can even be upgraded to adapt to the mooring requirements of up to 300 tons of load.
Strong corrosion resistance: After special surface treatment processes such as polishing, hot-dip galvanizing, or epoxy coating, the bollard can resist the corrosion of salt spray, seawater, and humid air in the marine environment. Compared with ordinary steel components, it has a longer service life and reduces the frequency of replacement and maintenance in harsh marine conditions.

Manufacturing Process:

Precision Casting: First, according to the design drawings of 150T load-bearing standards, a casting mold is made. The molten high-quality cast steel is poured into the mold. After cooling and forming, preliminary shaping is carried out to ensure that the overall structure meets the basic size requirements, and the key stress parts are thickened and reinforced.
Structural Reinforcement: In order to improve the load-bearing capacity, reinforcing ribs or thickened bases are added to the bollard. The base is designed to match the bolt installation or welding requirements, so that the tension can be evenly transmitted to the dock or ship deck structure during use, avoiding local stress concentration.
Surface Treatment & Inspection: After casting and forming, the bollard is polished to remove surface defects. Then, anti-corrosion treatment such as epoxy coating is carried out. Finally, strict load-bearing tests are conducted. Only the products that can bear 150 tons of tension stably can leave the factory. Many products also pass certifications of classification societies such as LR, ABS, and CCS to meet international marine standards.

Features:

 

 

Stable and Durable: The cast steel structure and reinforced design make it have strong impact resistance and long service life. It can maintain stable performance under long-term high-frequency mooring operations in busy ports.
Easy to Install and Maintain: It adopts bolted fixing (7 M48 bolts for 150T type). The installation process is simple and efficient. The anti-corrosion coating on the surface reduces the later maintenance work, and only regular inspection of the coating and bolt tightness is needed.
Strong Adaptability: It is suitable for different mooring angles. Whether it is the mooring of ships at the dock or the temporary fixing during the berthing of large ships, it can play a reliable role, and can adapt to the harsh marine environment such as salt spray and wave impact.

Technical Parameters:

 

Application Scenarios:

1.Large Commercial Ships: It is widely used for mooring large ships such as cruise ships, super container ships, and large oil tankers. When these ships berth at ports for loading, unloading, or passenger transfer, the bollard can firmly fix the mooring lines to ensure the ships' stability.
2.Port and Dock Facilities: It is installed on docks, piers, and dolphins in major coastal ports and inland river ports. It is used to cooperate with the mooring operations of various incoming and outgoing ships, which is the core mooring equipment to ensure the orderly operation of the port.
3.Special Marine Vessels: It is also applicable to large marine engineering ships, offshore platform supply ships, etc. When these ships carry out operations such as offshore construction and material transportation, the 150T bollard can provide stable mooring support to ensure the safety of on-site operations.

Quality Assurance and Certification Services

Strict Quality Testing

Raw Material Inspection: Steel undergoes tensile strength (≥800MPa) and impact toughness (≥20J/cm²) testing, while cast iron undergoes hardness (HB180-220) and metallographic analysis.

Manufacturing Process Control: Utilizing processes such as die casting and CNC machining, we ensure dimensional accuracy (e.g., column verticality deviation ≤ H/1000) and surface quality (sandblasting and rust removal to Sa2.5). Finished Product Testing: Corrosion resistance is verified through a destructive test at 125% of the rated load (no plastic deformation after 30 minutes of load holding) and a salt spray test (no corrosion after ≥1000 hours in a neutral environment).

International Certification Support

We provide certifications such as ISO 13795, GB/T 25010, ABS, DNV, and Lloyd's Register to ensure compliance with international port access standards.

We support customers in completing on-site classification society inspections, including welding procedure qualifications and non-destructive testing (such as magnetic particle inspection) according to DNV specifications.
