Fourth Transmission Pipeline Stage 2 (FTP2)

Project Capabilities

Building Civil Electrical Mechanical Pipelines

The FTP2 Project was awarded to McConnell Dowell Constructors Thailand Limitedby PTT Public Company Ltd (PTT).

The project involves approximately 70 km of 42" high-pressure gas pipeline constructed between Rayong LNG Terminal in the south to the Wang Noi – Kaeng Khoi Pipeline Tie-in Station in the north. Work is spread over
300 km and involves more than 20 km of trenchless pipe installation and construction of significant above-ground facilities.


  • 3km of Thrust Bores
  • 20km of horizontal directional drills and direct pipe installation
  • 18 Block valves
  • 2,800 person peak workforce
  • Over 4 million hours worked LTI free

Project Overview

Customer: PTT Public Company Limited
Location: Rayong, Thailand
Contract Type: Construct only
Construction Period: 16 months

The Challenge

The peak site workforce has exceeded 2,800 across 50 discrete work locations. At peak construction, key equipment included six HDD rigs, two direct pipe rigs and six thrust boring rigs operating concurrently, in addition to conventional pipeline installation and facilities construction teams. Much of the work has been undertaken in brownfield environments adjacent to busy highways, utility services, watercourses and residential and commercial dwellings.

The Solution

More than 5 million hours have been completed LTI free. This milestone has been attained while delivering a complex, fast-track project with significant terrain, environmental, safety, logistical and stakeholder challenges

Key to Success

Proactive safety management has contributed significantly to the project’s success. This has included a tailored project induction, timely and consistent communication with all stakeholders and innovative engineering solutions. These have been effective in mitigating risk to the workforce and general public. The depth of experience in similar works provided by long-term McConnell Dowell Thai and expatriate staff is also a key success factor.
