IGEM LSE - Repairing, Assessing and Rehabilitating the Networks


Get Directions

#var:page_name# cover

Join the London, Southern and Eastern Section for a discussion on the innovative techniques that have been designed for repairing, assessing and rehabilitating Gas Distribution Networks.

Asset management can be costly and a challenging process. To increase accuracy and productivity it’s important to find effective and efficient solutions, from inspection to repair, which can be carried out with the least amount of disruption for the general public.

At this presentation evening, Aquam Pipe Diagnostics (APD) and Nu Flow Technologies will discuss their latest technologies and how these can aid with repairing, assessing and rehabilitating the Networks

APD (formerly JD7), who are part of the AQUAM Corporation, are a specialised service and technology provider for:

• focused leakage detection,
• pipeline assessment and inspection solutions,
• rehabilitation and repair methods for gas and water applications.

APD can accurately pinpoint escapes in readiness for repair of the Network, providing condition assessment and pre-enabling activities. They have been providing their Gas Investigator system to Northern Gas Networks for over three years. This technology incorporates high-resolution CCTV camera sensors and a highly sensitive acoustic sensor coupled with a sonde. The acoustic sensor is used for precise leak detection pinpointing in all materials and pressures and the accompanying software provides the operative with live viewing and recording throughout surveys.

Tom Hives, International Operations Manager at APD, will talk about the APD journey, describe the technical capabilities of the Gas Investigator and what benefits and results it can deliver. He will also talk about other systems capabilities and what the future holds.

After assessment and a positive survey it’s crucial to be able to repair and restore gas risers quickly and with ease. The Nu Flow internal epoxy coating system is an Ofgem sponsored innovation for Cadent Gas and tRIIO. It is currently being trialled in London and is being used to re-life the existing steel risers in Multi Occupational Buildings (MOB).

This is an opportunity to hear about what the challenges are and the approach that is being taken to advance the innovation.This methodology is particularly interesting in terms of the size of the MOB estates across the GDN’s and the potential to rehabilitate existing assets.

Stuart Stevens, Head of Operations for APD, will present on the Gas Riser Remediation journey with Cadent Gas and tRIIO and what potential that holds for ‘re-lifing’ of existing riser installations.

Registration opens at 17:30 for a 18:00 start.
