Multifunctional floating type natural gas liquefaction ship for deep sea oil-gas field development and utilization

Abstract

The invention discloses a multifunctional floating natural gas liquefaction ship for deep and far sea oil-gas field development and utilization, which comprises a floating ship body, and a liquefied natural gas production system, a natural gas power generation system, an emergency rescue area, a personnel shift and material supply area, a seabed detection and underwater detection system and a seawater desalination system are arranged in the floating ship body. The multifunctional floating type natural gas liquefaction ship for deep and far sea oil-gas field development and utilization integrates multiple functions of liquefied natural gas production, power generation, seawater desalination, liquefied natural gas storage and filling, ocean monitoring and detection, emergency rescue providing and the like; the system supplies fresh water, supplies power and the like to island reefs in the ocean-going sea area to meet the requirements of green development and comprehensive utilization of the island reefs, supplies liquefied natural gas fuel to transport ships, carries out emergency rescue on the ocean-going sea area, and completes ocean monitoring and detection of underwater, water surface and space of the ocean-going sea area.

Description

technical field [0001] The invention relates to the technical field of marine engineering, in particular to a multifunctional floating natural gas liquefaction ship for development and utilization of deep sea oil and gas fields. Background technique [0002] my country is a big energy consumer, and natural gas is a green and low-carbon energy that my country focuses on. At present, my country's natural gas dependence on foreign countries exceeds 45%. It is expected that my country's natural gas consumption will continue to rise until 2050. my country is rich in offshore oil and gas resources, and the proportion of natural gas is high. Most of my country's self-sufficient liquefied natural gas (LNG for short) comes from deep sea areas. At the same time, my country also has nearly 80 billion tons of natural gas hydrate resources. [0003] Floating Liquid Natural Gas (FLNG for short) is a new type of FPSO device proposed by the marine engineering community in recent years, whic...
