Regarding the oil transfer arm and flexible metal hose
Thread Content
The company has two chemical terminals in total, and there are two ways in which the terminal deck is connected to the ships: oil transfer arms and flexible metal hoses. Some materials are connected to the ship using oil transfer arms, while others are connected directly with metal hoses. Under what circumstances is it necessary to use an oil transfer arm? Are there any regulations, standards, or practices in this regard?
Currently, the State Council’s Work Safety Supervision Office has a regulation stating that liquefied gases such as liquefied petroleum gas, liquid chlorine, and liquid ammonia must not be filled using hoses; no such requirement applies to other types of media. There are posts on forums discussing the advantages and disadvantages of oil transfer arms and hoses, which the original poster can search for as reference.
Depending on your usage needs, use hoses for smaller berths and oil transfer arms for larger ones; oil transfer arms are more stable and offer a higher flow rate, while hoses are more flexible
