Upgrade of PCS brings higher Operation Efficiency and Productivity at Gas Liquefaction Plant in Oman

suc-OmanLNG-002.jpgOman Liquefied Natural Gas LLC (OLNG) is a limited liability incorporated joint venture company established by a Royal Decree and operated under the laws of the Sultanate of Oman. It engages in the business of producing and selling liquefied natural gas (LNG) and byproduct natural gas liquids (NGL).

The Company undertakes, directly or indirectly, project operations and activities necessary to liquefy, store, transport and market Oman’s natural gas and to deliver LNG to customers in the global markets. The Company operates three liquefaction trains at its site in Qalhat near Sur with a capacity of 10.4 million tonnes per annum.

The produced gas at the Barik, Saih Nihayda and Saih Rawl gas fields are gathered at the Saih Rawl Plant - a gas field complex operated on behalf of the Government of Oman by Petroleum Development Oman (PDO) - in Oman’s interior. From there, a gas pipeline approximately 360 kilometres long and 48 inches in diameter with a gas capacity of 34 million cubic meters a day, is delivered to OLNG where the gas is liquefied.

The LNG production trains 1 and 2 located at the OLNG plant have been using Yokogawa CENTUM CS production control system (PCS) since 2000, and train 3 has been controlled by CENTUM CS since 2005. There have been no major issues in the process control systems over the course of these years.

With the discontinuation of the UNIX OS system, OLNG decided to take a phased approach to upgrade its systems from CENTUM CS to CENTUM VP for all liquefaction trains, a common facility upgrade involving other systems like Exaopc stations used for PI, APC (Exasmoc, Exarqe), and metering. Yokogawa’s eLogBook, an electronic logbook, is now an integral part of the OLNG day-to-day operations. Operator logging and handover applications are easily handled by this eLogBook. In addition, the central control room (CCR) renovation has been completed.

Yokogawa Releases Plant resource Manager (PRM) R3.20

Yokogawa PRM.jpgYokogawa Electric Corporation announces the July 2 release of version R3.20 of its Plant Resource Manager (PRM) software tool for the centralized management of large amounts of data from plant monitoring and control devices and manufacturing equipment. PRM R3.20 is an upgrade to R3.12 and includes an improved management function for HART and ISA100 Wireless™ field devices. With this new PRM version, Yokogawa aims to capture a larger share of the plant maintenance market.

Development Background:  Manufacturers are constantly looking for ways to improve maintenance efficiency by using software tools like PRM that can centrally manage large amounts of maintenance and other types of data from plant monitoring and control devices and manufacturing equipment. Maintenance personnel use such data to reduce plant downtime and enhance safety by proactively spotting and responding to device failures.  To optimize plant operations, it is essential not only to keep devices in good working order but also to have up-to-date information on device status and maintain records on all maintenance work that is performed. Such information is most useful if operators can view it on screen at their control system human interface stations.  With such needs in mind, Yokogawa has developed new functions for its PRM tool that facilitate the collection of information from field devices for use in optimizing device maintenance and plant operations.

1. Quick access to HART device status information

2. Various management functions for field wireless devices

3. Complying with FDT2.0, the latest FDT standard

Yokogawa delivers Community Energy Management System to F-Grid Ohira, Miyagi LLP

Yokogawa Solution Service Corporation, a subsidiary of Yokogawa Electric Corporation that is responsible for the company's control business in Japan, announces that a community energy management system (CEMS) that it has built and delivered to the F-Grid Ohira, Miyagi Limited Liability Partnership (LLP)* is now fully operational. The LLP is headed by Toyota Motor Corporation. Over a two-year period, this system was developed by the LLP, built by Yokogawa, and field tested. Funding for the testing of this system, which was developed as part of a smart community project undertaken by the LLP was provided by the Japanese government.

This LLP's CEMS optimizes the use of electricity by balancing the supply of power from the LLP's own natural gas cogeneration and solar power facilities with the purchase of electricity from the local power utility, and efficiently controls the supply of electricity and heat to the members of the LLP. From each of these companies' facilities, the CEMS collects data on electricity and steam demand, and, based on electricity and gas tariffs, calculates how much power should be generated by the LLP's own power systems. In the aforementioned field testing of the CEMS (April 2013 to March 2015), the LLP members reduced their energy costs by 20%.

The LLP's CEMS has a function that can also predict the energy demand at individual plants by collecting data that is strongly correlated with energy demand. Based on these estimates, the CEMS can be used to plan the optimization of electricity and heat supply by, for example, adjusting the operation of the gas cogeneration system. The LLP members can also compare these demand estimates with actual results and use this to make adjustments that will save more energy.

The CEMS is connected with a backup power system and plug-in hybrid vehicles that can feed power to LLP members and the local community when there is a temporary interruption or shortfall in the supply of power from the grid. By encouraging plants to voluntarily participate in this electric power sharing scheme, the LLP has established a foundation for the full implementation of demand-response policies that will mandate such cooperation.

In the future, Japan's energy policy will require communities and plants to make adjustments in energy supply and demand. By leveraging the expertise gained from its participation in the development of this CEMS, Yokogawa will be able to contribute at the regional level in building a distributed energy infrastructure.

Yokogawa releases Enterprise Pipeline Management Solution

Pipeine Management Yokogawa.jpgYokogawa Electric Corporation announces the June 30 release of the Enterprise Pipeline Management Solution (EPMS), a modular software suite that is the product of our over 20 years of practical experience in implementing pipeline management solutions across the globe.
