YTL PowerSeraya Pte. Limited.
YTL PowerSeraya Pte. Limited. is in the business of producing, wholesaling, trading, and retailing of energy, with a primary focus on electricity. With its strategic location on Jurong Island and excellent infrastructure, the Company has built an integrated energy business which includes the sale of steam and water as well as oil trading and storage.
YTL PowerSeraya’s desalination plant converts seawater into potable drinking water and service water for its existing boiler plants and utilities operations. It can produce 10,000 m3 of water per day. All operations at this plant are monitored and controlled by an integrated STARDOM and FAST/TOOLS SCADA system. Installed on a very tight schedule by Yokogawa Engineering Asia, this system has been in operation since September 2007 and has experienced no major system problems. The high reliability of this SCADA system is managed by the O&M staff of YTL PowerSeraya.

The Challenges and the Solutions
The first challenge in the YTL PowerSeraya desalination project was a very tight schedule. Working flawlessly from start to finish of this project, Yokogawa Engineering Asia was more than up to this challenge. A key advantage was that the company is a one stop provider not only of STARDOM controllers and the FAST/TOOLS human machine interface (HMI), but also various kind of field instruments.
Yokogawa also provided comprehensive engineering services, from the formulation of control strategy to the installation and commissioning of the integrated system. Approximately 1,400 I/O points were wired in/out at the STARDOM controller panels in the desalination plant's main control room. With this integrated system, all the real time process data can now also be monitored from the administration and turbine buildings via a dual redundant fiber optic cable network.
YTL PowerSeraya needs a constant supply of water for its boiler plants, ensuring the steady generation of power around the clock, 365 days a year. The quality of this service water is tightly monitored and controlled by Yokogawa conductivity and pH meters. Accurate measurements of the conductivity and pH readings in the salt water reverse osmosis (SWRO) membranes are important for the quick detection of any seawater leakage. This contributes to a longer SWRO membrane life and reduces TCO.
At this plant, Yokogawa magnetic flowmeters also help to keep costs down by accurately measuring the consumption of many different types of chemicals.

Abdul Rahim Sapuan, Team Leader of the Multi Utilities-Gen Dept. said, “We are very happy with Yokogawa’s proven SCADA system which helps to produce a constant supply of water to our boiler plants. The reliability of Yokogawa’s system and products is excellent. We can produce the water and constantly supply it to the boiler plants.”
The demand for seawater desalination as a stable water resource has been increasing. Yokogawa has a wealth of experience in controlling various types of desalination plant such as reverse osmosis (RO), multi-stage flash (MSF) and multi-effect distillation (MED). Yokogawa provides advanced solutions such as operator training simulators for stable plant operation.
Water resources are finite, and therefore contributing to a sustainable water cycle is one of the Sustainable Development Goals (SDGs). Yokogawa has been providing advanced digital control solutions for the stable supply of clean and safe water, wastewater treatment for protecting the water environment, water loss management and optimization of plant operation for reducing CO2 emissions and running costs. With our leading-edge technologies, dependable products and extensive expertise and experience of diverse water projects around the world, we work with you to provide sustainable water solutions that boost your business and add value throughout the plant lifecycle.
Yokogawa supports a wide range of water control applications in both the municipal and industrial water markets.
The brick type model FCJ autonomous controller fulfills the basic requirements of the utility control. It also provides the reliability for the SCADA communication with network redundant capability.
The low power consumption model of the field control node (FCN) autonomous controller meets the demanding requirements at inhospitable remote locations which lack power.
Originating as the Flexible Advanced System Techniques (FAST) project, FAST/TOOLS today is a comprehensive, fully-integrated SCADA application suite. Powerful and flexible, FAST/TOOLS serves installations ranging from 50-point unit processes to multimillion-point offshore production and pipeline systems that extend over thousands of miles.
From process plants to remote locations, our process control PLC and Remote Terminal Unit (RTU) help users maximize operational excellence.
