Ship-shore interface safety device

During the loading process of liquid ships, the oil and gas recovery pipeline is filled with oil and steam and mixed with other gases (even oxygen). Oil and gas is a high-risk substance. The concentration of oil and gas may be within the explosion limit, and the combustion or explosion spread of oil and gas is very fast. Therefore, the safety requirements of gas phase pipeline should be higher than that of liquid phase pipeline. Therefore, the safety device of the ship and shore interface shall be set in front of the oil and gas recovery device at the wharf.

The safety device at the shore interface of the oil and gas recovery ship at the wharf refers to the safety device set at the front of the wharf, with the front section (inlet end) connected to the gas transmission arm or hose, and the end (outlet end) connected to the gas transmission pipe network, which realizes the functions of overpressure relief, isolation, oxygen content monitoring, and fire resistance at the front and rear ends, effectively monitors the pressure and temperature of the oil and gas during the loading process, and reacts to the excess value, including directly cutting off the oil and gas transmission and adjusting the oil and gas transmission, Prevent the occurrence and spread of safety accidents.

Composition and function description

The ship shore interface safety device and the berth are in a one-to-one mode, that is, one berth is equipped with a set of ship shore interface safety device, and each set of ship shore interface safety device should include emergency evacuation, shut-off valve, filter/gas-liquid separation, explosion arrester, pressure sensor, differential pressure sensor, temperature sensor and other equipment.

The ship-shore interface safety device is equipped with a full-automatic control system to collect the data of all equipment on the pipeline, analyze the collected data, judge the operation of the system, send correct operation instructions through logical control, realize the functions of overpressure relief, isolation, oxygen content monitoring, front and rear end fire resistance, and ensure the long-term effective and safe operation of the system.
