Design and Structure

Distinguished colleagues and partners in the industry:

In the era of the booming development of the water transportation industry, the safety and efficiency of ship berthing have become the key elements of terminal operations. With enthusiasm and pride, we officially present to you the meticulously crafted T-shaped cast iron bollard. It integrates advanced design concepts and excellent structural craftsmanship, and will bring about a brand - new transformation in the field of ship mooring.

I. Design Concept: The In - Depth Integration of Safety and Efficiency

1. Oriented by Ship Operation Requirements

We have conducted in - depth research on the force characteristics of ships during different operation scenarios such as berthing, unberthing, mooring, and shifting berths. It was found that traditional mooring bollards have certain limitations in dispersing mooring forces. Based on this, the design of the T - shaped cast - iron mooring bollard came into being. Its unique T - shaped structure effectively increases the mooring contact area and can evenly disperse the pulling force generated during ship mooring, avoiding local stress concentration and ensuring that ships can be stably berthed under various complex sea conditions.

2. Improving Terminal Operation Efficiency

In terminal operations, time is money. The design of the T - shaped cast - iron mooring bollard optimizes the mooring operation process. Crew members can complete mooring and unmooring operations more conveniently and quickly, greatly shortening the ship's stay time in the port, improving the port's throughput capacity, and bringing higher economic benefits to port operations.

II. Structural Analysis: Robust and Durable, Unafraid of Harsh Environments

1. High - Strength Cast Iron Material

The T - shaped cast iron mooring bollard is made of high - quality HT200 cast iron. This material has excellent strength and impact resistance, and can easily withstand the erosion of harsh marine environments. Whether it is long - term seawater immersion, the blowing of sea breeze, or the strong pulling force during ship mooring, it can maintain stable performance, ensure long - term reliable operation, and reduce maintenance costs and replacement frequencies.

2. Scientific and Rational Component Composition

● Robust Shell: As the main load - bearing structure, the shell is designed with thickening. It can effectively withstand the pulling force and impact force during ship mooring, and protect the internal structure from damage.

● High - Strength Anchor Bolts: Penetrating deep into the dock foundation, they cooperate closely with nuts, washers, and anchor plates to firmly fix the mooring bollard on the dock ground. The high - strength material and special design of the anchor bolts ensure that they will not loosen or break under extreme working conditions, providing a solid guarantee for the stability of the mooring bollard.

● Lock Nuts and Thickened Washers: They further enhance the connection reliability, prevent the nuts from loosening due to vibration and shaking during ship mooring, and ensure that the mooring bollard is always closely connected to the dock foundation.

● Large - Size Anchor Plates: Increase the contact area with the foundation, disperse the pulling force borne by the mooring bollard, make the mooring bollard more stable when under force, and effectively prevent the mooring bollard from being pulled out or displaced.

● High - Performance Core Fillers: Filled in the shell, they play a buffering and sealing role. During ship mooring, they can absorb part of the impact force, reduce damage to the structure of the mooring bollard; at the same time, the sealing performance effectively prevents seawater, impurities, etc. from entering the interior of the mooring bollard, extending its service life.

3. Optimized Connection and Anchoring Methods

The connection between the anchor bolts and the dock foundation is specially designed. High - strength bolt anchoring is adopted, and it is combined with large - size anchor plates, which greatly increases the connection strength between the mooring bollard and the dock foundation. After multiple rounds of simulation tests, the T - shaped cast iron mooring bollard can still remain stable under extreme working conditions such as strong winds and huge waves, ensuring the safety of ships.
