LNG再气化和储存

• World's largest LNG terminal relies on CENTUM to maximize safety and reliability.
• It is very important for KOGAS to be able to adjust flexibly to shifts in demand in the gas that it supplies to power plants, industrial companies, and residences.

• DCS, SIS, PRM with FOUNDATION fieldbus and OTS Installed in Thailand First LNG Terminal.
• Alarms are issued before any device fails completely, enabling predictive maintenance that reduces maintenance costs throughout the facility lifecycle.

• Yokogawa provides CENTUM CS 3000 and ProSafe-RS for the largest LNG terminal in Europe.
• Yokogawa's OmegaLand plant operator training simulator (OTS) helps to reduce costs, optimize LNG terminal processes.

• World's first offshore regasification terminal relies on Yokogawa ICSS (CENTUM CS 3000, ProSafe-RS).
• LNG carrier scheduling, unloading, tank storage, and vaporizing are all procedure based operations.

• Legacy ProSafe-PLC SIS replaced with ProSafe-RS to improve sustainable lifecycle support at LNG terminal.
• The seamless use of the same HMI for both PCS and SIS, and improved safety and integrity.

• Scalable, flexible configuration with functions distributed to multiple controllers on a facility basis
• Redundant architecture optimally designed for requirements of entire plant
• General-purpose communications network used for control bus
• Integrated operation environment through web-based human-machine interface (HMI)

An automatic custody transfer system for unmanned LNG gas stations that embeds PC oriented functions such as e-mail, FTP, and the Java runtime environment in a robust hybrid controller.

Over the past decade, companies have been using unconventional drilling technology to extract gas and liquid from the readily available shale formations in North America. As the industry gains experience, the production rates continue to rise based on better use of technology to locate resources and to decrease the time from exploration to production.

As LNG moves from a niche to a major area of the oil and gas industry, experienced suppliers are required to deliver the technologies that support it.

Martin te Lintelo, Yokogawa Europe B.V., The Netherlands, discusses high level control system design for LNG receiving terminals. As demand for LNG increases worldwide, players face seemingly conflicting challenges. On one hand, they must expand capacity in different regions, make the business and production as agile and adaptive as possible, and improve operational efficiency.

The LNG sector presents challenges for the automation supplier, particularly in the implementation of automation systems for regasification terminals. Yokogawa Europe's business development manager, upstream oil and gas Martin te Lintelo looks at the handling of the potential automation-related problem areas and opportunities.
