LNG Regasification & Storage

44 regasification terminals use Yokogawa's DCS.

Advanced Terminal Unit Control (ATUC) and Advanced Gas Send-out Control
Yokogawa's field-proven Advanced Terminal Unit Control (ATUC) and advanced gas send-out control technologies enhance unit management and simplify operator decision-making during the startup and shutdown of major plant assets, thus preventing inconsistent operating conditions. Through Enhanced Unit Management (EUM) concepts such as optimized load sharing, our customers can increase the operational efficiency and life span of their plants' major equipment. ATUC greatly improves the stability of gas send-out by anticipating disturbances such as a pump being switched off by an operator. Although simple continuous feedback control can also respond to such disturbances, the time needed to recover always incurs a loss. Only Yokogawa offers ATUC. A VigilantPlant® library of ATUC and other engineering templates are also available.

Overview:

Risk management is crucial when expanding your business.

Overview:

In the event of a gas line shut down, gas supply must be maintained for a period of time with the use of LNG stored in road tankers. Each tanker must have its pressure monitored to prevent an over pressure situation arising.

Overview:

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.

Overview:

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. 

Overview:

July 2010

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.

Overview:

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.
