Project GRAID is scheduled to last three years and will be broken down into eight clear milestones with pre-determined dates for delivery.
The first of these milestones is called solution development and the deadline for completion is October 30, 2015.
Sept 9, 2016
Phase two of the project requires NGGT to develop and validate access and inspection routes for the robots at all three trial sites, as well as formulating Formal Process Safety Assessments.
A really important part of the project will be the testing process and this milestone requires NGGT to commission a bespoke pipe configuration that will be used for offline testing.

Offline testing is one of the most essential aspects of the development programme and absolutely critical to the success of the project.
Milestone three will see offline testing completed to ensure the robot is able to operate effectively in conditions found in live gas installations.

Online testing is the next critical stage for the project. Testing decreases the chances of the robot failing on a live installation, minimising the potential operational repercussions on UK gas consumers.
The online testing phase will see the successful insertion of the launch and retrieval device at all three live sites. NGGT will then undertake testing in order to refine and deliver a robot that can deliver the project’s objectives – to work up to pressure of 100 Barg, travel 100m, and collect visual inspection and wall-thickness measurements.

Milestone five will see NGGT complete testing of the robot in order to deliver a functional robotic platform that can work at pressure of 100 Barg, travel 100m, negotiate two bends and provide condition-assessment data (visual and wall-thickness measurements). There will be a minimum of 10 offline and three online tests.
The functional robotic platform, called the Delta prototype, will be completed by March 26, 2018.
Data analysis systems
Jul 6, 2018
Milestone six will focus on the project’s data analysis systems and see NGGT collaborating closely with project partners Pipeline Integrity Engineers (PIE) Ltd.
An analysis of the data collected by PIE will be delivered. A condition assessment of the algorithms the company has developed to turn the data into meaningful intelligence will also be carried out.
Conduct data analysis
Sep 3, 2018
All data analysis will be completed at milestone seven. This will include a review of all the proposed algorithms to determine any changes that need to be made to the inspection equipment.
A data analysis completion report will be submitted by September 3, 2018. A report will also be produced by NGGT to mark the successful delivery of condition assessment through robotic data collection and the use of algorithms.
Implement into business as usual
Nov 12, 2018
The final milestone of this exciting and ambitious project will see the technology implemented into ‘business as usual’.
A pre-commercialised in-line inspection platform will have been designed, manufactured and delivered. Specifications of the robot will have been checked and approved to confirm they are suitable for company use by National Grid.
