Description

Technical Field

[0001] The present invention relates to an oil transportation device. Background Art

[0002] A floating production storage and offloading vessel is a ship that integrates production processing, storage and offloading, as well as living and power supply. The floating production storage and offloading vessel is like an "offshore oil and gas processing plant" that processes the mixed liquid of oil, gas and water from oil wells into qualified crude oil or natural gas. The finished crude oil is stored in the cargo oil tank and transported to the shuttle tanker through the offloading system when it reaches a certain storage capacity. Offshore oil transportation is very different from traditional onshore oil transportation. Generally, an oil transportation ship docks with a floating production storage and offloading vessel through an oil pipeline. However, there is a problem of poor sealing during the docking process of the oil pipeline and the storage ship, and some oil may seep out from the interface, affecting the oil transportation.
