As the saying goes, a worker must first sharpen his tools if he wants to do his job well. In the process of ship fluid transportation, the ship loading arm is indispensable. So, what are the common forms of marine unloading arms?
The following is the outline:
What are the common forms of marine loading arms?
What are the characteristics of the single-tube loading arm?
What are the characteristics of the double-tube loading arm?
Self-supporting single wire arm. The extension of the arm is completed by the swivel. The overall structure is simple and dexterous, which is suitable for small ships. There is also a hybrid single-tube unloading arm, which is supported by an auxiliary support mechanism, which is suitable for larger tonnage ships.
The branch supports the unloading arm. Its overall weight is carried by the external support. Therefore, the pipeline and rotary joint have no external weight added, which is suitable for long-term petrochemical operations.
Branch double tube unloading arm. The two pipelines operate independently, and one additional pipeline is used for gas circulation. In this way, liquid and gaseous products represented by liquefied natural gas can be transported more safely and without loss.
Lighter weight. Generally speaking, the single-pipe unloading arm does not have cumbersome rotary joints and control equipment, and only relies on integrated pipes for fluid transmission. Relatively speaking, it is more flexible and maneuverable, suitable for small ships or as a substitute.
Swivel connection. This connection method is a bit similar to the roller-skate device in physics, which controls the direction of wingspan through different forces in different directions.
Shorter arm length. The integrated single-tube unloading arm does not have a strong support system. Therefore, its arm span is limited to a small range to meet the needs of small equipment.
Structural support bears the type. The double-tube unloading arm has its own set of structural system, which is similar to a house with a well-founded frame and is more stable. Therefore, the pipes and joints on the arm do not need to be loaded with weight, and are more durable and easy to use.
Suitable for different fluid forms. Among them, the branched double-pipe unloading arm is equipped with two pipelines, which can be connected and interconnected with gaseous liquid pipelines, which meets the diversified transmission and storage requirements, and is especially suitable for the transmission of liquid natural gas.
Suitable for large ships. With its own structure, the double-tube unloading arm with long arm span and tight knobs can better meet the transmission needs of large fluids. On large docks, fluid distribution can be completed when the tanker is floating freely.
In short, the common forms of marine loading arms mainly include self-supporting single-line arms and double-pipe unloading arms. Lianyungang Loadarm Industry Co., Ltd. (LICO) is a company directed in the production, manufacturing and sales of fluid loading and unloading equipment. For more knowledge about marine loading arms, please come to consult.
