Introduction: The scope of work includes:

Design and install a 1.4kM 19 bar pipeline
Establish construction methods including jointing, pressure testing & commissioning.
Establish training requirements for all aspects of the installation e.g. jointing
Confirm HSE acceptability
Identify and manage risks
Establish actual benefits, in particular capex and opex
Compile report for dissemination of findings to the wider industry
Establish way forward to allow 19 bar PE to be implemented safely and efficiently in UK

Objectives:

To demonstrate fitness for intended purpose of the RTP material in order to make a 19 Bar connection
To demonstrate the productivity benefit that can be gleaned from deploying this material c/w steel
Confirm the effectiveness of No-dig techniques
Estimate the whole life costs and hence reduction in costs compared with steel

Expected Benefits:

The installation of the 19 bar PE pipeline is completed, and a conclusion can be made on its potential effectiveness in the UK network.
The use of the material demonstrates an installation cost benefit compared with steel
