Background of This Project

PTTEP, Thailand
PTTEP, Thailand

With the Arthit project, PTT Exploration and Production Plc. (PTTEP) has for the first time engaged in every stage of developing a new gas field, from exploration to production. For this project, PTTEP built the Arthit Central Processing Platform, one of the largest of its type in Asia and the first ever in Thailand to be moved into position using the floatover method. It is located in the Navamindra Petroleum Area, which is in the Gulf of Thailand about 230 km off the coast of Songkhla Province. At this location, the water depth is approximately 80 meters. In the first project phase, six wellhead platforms have been connected to the central processing platform. Ultimately, 50 wellhead platforms will be constructed.

Production Overview

  • Natural gas exported to PTT Riser Platform via a 42 inch, 200 km subsea pipeline
  • Daily contractual quantity of 330 MMSCFD
  • Maximum daily quantity of 363 MMSCFD
  • Stabilized condensate exported to Bongkot FSO2 via an 8 inch, 30 km subsea pipeline
  • Production rate: 15,000 to 20,000 BPD

About PTTEP

PTTEP is the first and only Thai-operated petroleum exploration and production (E&P) company. In line with a cabinet resolution calling for a flexible E&P entity that would provide maximum benefit to Thailand, it was established on June 20 in 1985 by the Petroleum Authority of Thailand (PTT). Its mission is to explore for, develop, and produce petroleum from onshore and offshore sources in Thailand and other countries.

The Challenges and the Benefits

A key challenge in this project was the tight schedule during the detail engineering and procurement stage. Yokogawa succeeded in delivering its systems on time and without compromise in quality.With an automation system comprised of the Yokogawa CENTUM CS 3000 Production Control System (DCS) and the ProSafe-RS Safety Instrumented System (SIS), this is the first offshore platform in Thailand that is designed to make full use of FOUNDATION fieldbus technology.

During the pre-commissioning work for the FOUNDATION fieldbus instruments, the challenge was integrating the CENTUM CS 3000 system with instruments from other vendors. With the great vendor support provided by the Yokogawa service team, all devices were successfully connected and full integration was achieved.

 

This platform also had many new operators who required training on an operator training system (OTS). An OmegaLand simulator provided by Yokogawa helped control room operators quickly come up to speed in running platform processes.

Thanks to Yokogawa's highly reliable systems and products, a safe working environment has been achieved for the 120 operators, engineers, maintenance staff, and other personnel stationed on this platform.

Customer Satisfaction

"A lot of modification and fine tuning of the automation system occurred during startup, but this was not difficult for Yokogawa. The system has a lot of capability and flexibility. With great support from Yokogawa Thailand, the DCS and SIS on the Arthit platform have met our requirements. During startup and commissioning of the platform, we never had problems caused by the Yokogawa system." Theeraporn Kongwilai, Instrument Engineer.

Industrias

  • Exploración, desarrollo y producción

    La industria de exploración, desarrollo y producción incluye actividades en altamar y terrestres, como la automatización de bocas de pozo, el fraccionamiento, la terminación y la separación para recuperar y preparar petróleo crudo y gas natural subterráneos o submarinos.

    A medida que el petróleo es llevado a la superficie, debe ser separado antes de su transportación. Las etapas de separación primaria y secundaria distribuyen comúnmente el flujo de gas, el flujo de agua y el flujo de aceite en tres fases. El movimiento del gas requiere ductos y puede incluir un procedimiento de fraccionamiento en la etapa de exploración, desarrollo y producción antes de su desplazamiento. Los líquidos se pueden colocar en tanques o tuberías y ser enviados para su procesamiento, que requieren mediciones de nivel precisas.
