Introduction to Marine Bridge Structures

Ship bridge is one of the important equipment on board, mainly used to install various pipelines and cables on board to support the items and equipment on board, ensuring the stability and normal operation of the ship. The following is a detailed analysis of marine cable trays:

1、 The function of marine bridge frame

Load bearing capacity: Marine cable trays can carry the weight of items on board, ensuring that items in the cabin do not move or lose control during travel.

Balancing the center of gravity: Marine bridge frames help balance the center of gravity of the ship, maintain stability when the ship is sailing on water, and prevent the ship from tilting or shaking up and down.

Enhance structural strength: provide additional support and structural strength for ships, helping them better resist sea environments such as wind and waves.

Convenient operation: making it easier for goods on board to arrive, facilitate selection or exchange.

2、 Standards for marine bridge frames

To ensure the safety and reliability of marine bridge frames, international classification societies and relevant organizations in various countries have introduced multiple standards to regulate the dimensions, materials, manufacturing processes, and other aspects of marine bridge frames

Size standards: including height, width, length, and other aspects. The height should comply with ergonomic principles to facilitate personnel operation; The width should meet the requirements of the pipeline or cable it carries; The length should be determined based on actual needs and the structure of the vessel.

Material standards: The manufacturing materials of marine bridge frames should comply with relevant standards, and common materials include steel, stainless steel, aluminum alloy, and carbon fiber. These materials each have their own advantages and disadvantages, such as high steel strength, good corrosion resistance, but heavy weight; Aluminum alloy is lightweight, corrosion-resistant, but expensive; Carbon fiber has the characteristics of light weight, high strength, but expensive price. Manufacturers need to choose suitable materials based on the specific situation and requirements of the vessel.

Manufacturing process standards: considering aspects such as processing, assembly, and inspection. Manufacturers should manufacture according to relevant standards to ensure that the products meet the requirements. During assembly, it is also necessary to follow relevant standards to ensure its safety and reliability.

3、 Application scenarios of marine bridge frames

Marine cable trays are widely used in various types of ships, especially in situations where a large number of pipelines and cables need to be installed. For example, on a cutter suction dredger, the bridge is used to install structures such as cutters, cutter drive devices, and suction pipelines to meet the needs of dredging operations.

4、 Maintenance of marine bridge frames

Marine bridge frames require regular maintenance and upkeep during use to ensure their normal operation and extend their service life. Maintenance work includes checking the fixing condition, anti-corrosion performance, and whether there are any damage or wear issues with the bridge frame. Once a problem is discovered, it should be repaired or replaced promptly to avoid safety accidents.

In summary, ship bridge is one of the indispensable and important equipment on ships. It carries the weight of the ship, balances the center of gravity of the vessel, provides additional support and structural strength, and facilitates operations on board. Therefore, in the design and construction process of ships, the requirements and standards of ship bridge frames should be fully considered to ensure the safe and stable operation of ships.
