Description

A floating natural gas liquefaction/gasification berthing of a liquefied natural gas transport/filling ship equipment

technical field

The utility model relates to the field of natural gas liquefaction/gasification production and transportation. In particular, it relates to a floating natural gas liquefaction/gasification equipment berthing a liquefied natural gas transport/filling ship.

Background technique

The development of offshore drilling and production technology has enabled the oil industry to produce in different regions of the world, and more and more natural gas is produced along with petroleum products. Due to the small scale and low output of associated gas on crude oil production platforms cannot meet the economic requirements of building submarine oil pipelines or building offshore devices to realize liquefied natural gas, and there is no economical and reliable recovery technology, so that the associated gas is removed by torch burning after gas-liquid separation, which pollutes the environment and wastes natural gas energy. At present, there are a large number of small marginal gas fields to be exploited in many regions of the world. Therefore, the production of offshore oil and gas urgently needs recovery technology and corresponding equipment for scattered natural gas.

Conventional berthing techniques typically used for shore-based or wharf LNG carriers are less suitable for small gas field or associated gas field platforms currently located offshore. During loading and unloading operations, especially in severe weather conditions such as strong winds and waves, it is necessary to maintain an effective distance between the floating berth and the gas carrier.

Contents of the invention

The purpose of the utility model is to provide a floating natural gas liquefaction/gasification equipment for berthing of liquefied natural gas transport/filling ships, so as to realize the production operation of berthing and transporting liquefied natural gas associated gas in offshore oil fields and small-scale gas fields.

The technical solution of the utility model is: a floating natural gas liquefaction/gasification equipment for berthing of liquefied natural gas transport/filling ships, including floating docks, natural gas liquefaction/gasification devices, living and living buildings for crew members, and positioning anchors system; the floating berthing dock is composed of a U-shaped box, and the bottom of the opening is provided with a connecting bottom plate; the natural gas liquefaction/gasification device is placed on the floating berthing dock, including a natural gas liquefaction/gasification production device and storage tanks; the positioning mooring device includes mooring anchor chains, quick release hook devices, fairleads and cable piles.

The utility model solves the problem of exporting and transporting liquefied natural gas on the current offshore gas field and offshore oil production associated gas platform, provides reliable production equipment for its production, has relatively large economic benefits and huge social benefits, and has low cost and high efficiency. High, flexible and convenient.

detailed description

Embodiment is illustrated below in conjunction with accompanying drawing:

The floating berthing dock 1 is a U-shaped box structure, one side of which is wide and the other narrow. 4. The anchor chain 4 is connected with the quick release hook; the upper edge of the floating berthing dock 1 is equipped with cable piles, and the inner cable piles are mainly used for mooring of liquefied natural gas transport/filling ships; A natural gas liquefaction/gasification unit 2 and a crew building 3 are arranged on the wide-side box; the natural gas liquefaction/gasification unit 2 includes a natural gas collection system, a natural gas desulfurization, decarbonization and dehydration system, a liquefaction system, a flash gas compressor system, Exhaust gas combustion system, refrigerant replenishment system, heat medium system, storage tank, unloading area. The waste gas combustion system mainly burns the combustible gas generated and leaked in each system. By adopting the mature technology of each functional processing system in the existing technology, the requirements for liquefaction of natural gas and transfer of loading and unloading can be realized.
