Novel emergency release device for stern oil receiving port of shuttle tanker

Abstract

The invention belongs to the field of marine oil and gas output, and relates to a novel emergency release device for a stern oil receiving port of a shuttle tanker. Quick connection of an oil pipeline and two release modes of active release and passive release in emergency can be achieved, and the safety of oil and gas output operation is ensured. According to the novel emergency release device for the stern oil receiving port of the shuttle tanker, a connecting mode that clamping jaws are evenly and circumferentially distributed is adopted, releasing and clamping functions of the clamping jaws are achieved through the combined action of hydraulic oil pressure in a driving mechanism and a female connector reset spring, and the clamping mechanism is provided with a self-locking structure; each clamping jaw is designed into a head part and a tail part, so that each clamping jaw can be separated by cutting off a broken pin in emergency; a female connector sealing spring is installed on the outer side of a female connector sealing ring, and a sealing ring is arranged between a limiting ring and the female connector sealing ring, so that media can be effectively isolated, and erosion of the media to the internal structure of the device is avoided. Compared with an existing device, the novel emergency release device for the stern oil receiving port of the shuttle tanker has the biggest characteristic that a passive separation mode is adopted, and connection and clamping are more reliable.

Description

technical field [0001] The invention belongs to the field of offshore oil and gas transportation, and specifically relates to a novel emergency disconnection device for quick connection and emergency disconnection of oil pipelines and bidirectional closing of oil passages, which can greatly improve the efficiency and safety of shuttle oil tankers receiving oil at sea. Background technique [0002] With the development of oil and gas resource exploitation in the offshore field, the safety of offshore oil and gas field exploitation has received more and more attention, among which offshore crude oil export is an important part of it. The emergency release device is an important part of the offshore oil and gas transportation system. It can not only improve the efficiency of the oil and gas transportation operation, but also realize emergency release under dangerous conditions and improve the safety of the oil transportation operation. However, compared with foreign countries, ...

AI Technical Summary

Problems solved by technology

However, compared with foreign countries, my country's research on offshore oil equipment started later and its technology is immature. Although my country has made many achievements in the research on the emergency release device of the wharf oil delivery arm, there are few studies on the emergency release device for offshore oil and gas transportation.
