LNG在腿上

A new frontier is on the gas market horizon: Offshore platform-based liquefied natural gas (PLNG).

The abundance of natural gas in the US along with the rising global demand of LNG, 尤其是在亚洲, is establishing a strong incentive for the development of innovative solutions to export LNG from the US.

Onshore LNG facilities have been the predominant industry solution since the 1960s for the import or export of LNG, 特别是基本负荷能力. But with the constant flux in market supply and demand dynamics, floating LNG (FLNG) facilities (offshore and near-shore) are becoming increasingly prevalent worldwide with a focus on lowering project costs, improving operating efficiencies and reducing execution schedules.

然而, 一个新的, 可行的替代方案已经出现, 受到FLNG和固定多平台的启发, 您可以在海上找到桥式连接的生产设施.

Wood is proud to have delivered front-end engineering design (FEED) for the world’s first offshore platform-based natural gas liquefaction and storage facility for Honghua Offshore and EnTX GasTek Global Ltd.

The Platform-based LNG solution (PLNG) is a unique proposition as it is the special combination of a well-established, industry-wide offshore solution – the fixed jacket supporting topsides processing facilities – with proven LNG processing equipment operating globally.

该项目位于西部三角洲地区, k现在n as LNG 21 is initially designed to include six modular natural gas liquefaction trains, 每个铭牌容量为 .833 MMtpa (million metric tonnes per annum) with the potential of up to 1.2 MMtpa每个，提供总最佳容量6.100万吨/年液化天然气.  Liquefaction modules will use field-proven Baker Hughes GE technology. fsb型铝储罐, 根据通用动力公司的许可开发, 能容纳300人吗,000立方米液化天然气卸至液化天然气运输船.  All modules will be installed on conventional fixed platforms designed by Wood

This project is designed as a world-first fixed-platform natural gas liquefaction facility with uncongested open-water access for LNG carriers, free of the coastal footprint that burdens shore-based facilities.  除了, the project resides in the center of one of the nation’s top natural gas production basins, 提供方便的途径获得丰富的天然气供应, with opportunities for off-take partners to diversify upstream for even greater supply certainty and price protection.

While it could create the opportunity to address mid-scale LNG import and export developments, 特别是在浅水区, 工程和设计并非没有挑战. One of the main design challenges is the right balance between deck and topsides configuration and jacket size, along with ease of transportation and installation while considering the size and weight of the topsides (i.e. 液化天然气储存), 土壤和海洋条件, and availability of global and local transportation and installation vessels.

Within the pioneering engineering and design scope our team had to consider the onshore gas pre-treatment plant configuration and layouts, 通用工具, feed gas processing and compression and transportation and delivery via repurposed pipelines from the existing onshore facilities in Louisiana to the LNG facility 10 miles offshore.

We were already on first name terms with the project having successfully completed the pre-FEED work, 优化设计以满足U.S. 安全及环境规例, as well as enabling the client to define the siting and installation strategies.

As a team we worked diligently to develop a visionary end result, 哪个变成了多个固定平台, bridge-connected scalable complex engineered to host and support a variety of LNG processing and storage systems on individual or multiple dedicated platforms. 独特的PLNG方法提供了一个安全的, cost-effective and time compressed schedule in executing mid-scale LNG developments between at-shore, 近岸及深水浮船.

The facility will be sited in the Gulf of Mexico in water depths of less than 200 feet (60 meters) providing flexible processing capability and LNG storage capacity to meet project needs. 一旦完成, 2020年左右, gas from the Texas Permian Basin will be transported to the offshore platform w在这里 it will be liquefied, 储存并最终出口到全球.

I will be discussing the merits of the offshore PLNG solution relative to other terminal options and describes various intricate aspects of the terminal and its individual components in much more details at the upcoming Gastech 2019 event in Houston, TX.

The presentation will outline safety considerations for this uniquely designed complex, 在其制造和施工中提供了固有的好处, along with innovative execution considerations in PLNG development.
