Function of the emergency release device of the oil loading arm

The oil transfer arm is a key loading and unloading equipment at the oil terminal. During the loading and unloading process of oil products, the oil tanker may need to leave the terminal quickly due to unexpected accidents (such as fire, typhoon and other unpredictable reasons), or drift away from the normal working area due to tidal range, wind, waves, currents and other reasons. The above working conditions require that the oil tanker and the oil transfer arm can be separated quickly, otherwise the oil tanker will pull the oil transfer arm, causing medium leakage, environmental pollution and fire hazards; severe pulling will cause the oil transfer arm to fall, causing more serious accidents and losses.
For this reason, many large oil terminals have installed expensive emergency release devices (ERS) on the three-dimensional joints of the oil transfer arm, which can quickly separate the oil transfer arm from the ship in case of emergency and emergency separation is required. When separating, under the action of the hydraulic system, the emergency release device is opened to separate the joint, the upper and lower butterfly valves are closed first, and then the upper and lower butterfly valves are cut off and separated. After separation, the upper cut-off butterfly valve rises with the outer arm of the oil transfer arm, and the lower cut-off butterfly valve remains on the tank ship. The leakage of the medium is prevented at the side of the oil transfer arm and the ship at the same time.
Shanghai EMINENT Enterprise Development Co., Ltd. has its own utility model invention patent on the emergency release device of the oil transfer arm: an emergency release device for fluid loading and unloading arms, patent number: ZL200420025919.8. This technology greatly improves the safety of the oil transfer arm in harsh natural working environments.
As a manufacturer of dock and petrochemical storage products, Shanghai EMINENT not only produces oil transfer arms, but also intelligent cable release hooks, hydraulic cranes, boarding ladders, land-based fluid loading and unloading arms (crane pipes), oil tank scrapers, central drainage systems, floating oil unloading arms, samplers, etc. The company also has many practical patents for these products. In 2011, the quick cable release hook stood out among more than 660 applications and won the first prize of the Second Shanghai Invention and Innovation Award.
