Geospatial Corporation uses ILIM programme on underground pipelines
Published by Lydia Woellwarth,
Geospatial Corporation has completed over a dozen quality assurance (QA) programmes and Installed Locational Integrity Management (ILIM) programmes for underground pipelines and conduits installed via horizontal directional drilling (HDD) methods regardless of depth, material or soil conditions. This service addresses the need for accurate 3D mapping of critical pipeline segments that exceeds regulatory requirements and supports integrity and reliability demands. The requirements proposed by the Pipeline and Hazardous Materials Safety Administration (PHMSA) will affect the entire 2.4 million miles of buried gas pipelines in the US.
Mark Smith, Geospatial’s CEO stated that “The Company has successfully completed approximately 100 QA programmes since January of this year for major energy companies across the country. In addition, we have a growing backlog of several QA and mapping projects. With the coming adoption of new Federal PHMSA regulations the need for energy companies to accurately map and manage underground pipeline data is huge and growing rapidly”.
Benefits to pipeline owners, designers, and engineers contemplating a re-route, re-locate and HDD installation:
- The pipeline industry is rapidly moving to 3D (plan/profile) mapping of pipeline assets. This includes those difficult to reach and high-risk segments.
- HDD has afforded the opportunity to go deep, much deeper than can be detected by conventional locating methods, so proactive pipeline owners are gathering important positional data before the line is put into service.
- Geospatial’s QA and ILIM programme provides accurate XYZ ‘as installed’ locational data, including depth for most underground and underwater pipelines and conduits regardless of size, depth or type of material.
- In addition to very accurate XYZ locational information, Geospatial provides detailed girth weld positions, alignment, and precise bend radius data at all points along the installed pipeline – this supports any ICDA or hydraulic flow analysis.
- Depth of cover can be computed with terrain or water bottom data and a caliper survey can optionally be included for complete geometry.
- The QA and ILIM programme, when coupled with GeoUnderground (the mobile GIS information management software platform), can provide field data collection of geo-referenced video of the pipeline interior and aboveground right of way physical features and appurtenances.
- A powerful ‘Library & Search’ capability to store, edit, manage and securely share important documents, photos, video and field data from your mobile device with work teams anywhere in the organisation.
- Peace of mind that the pipelines on your project have been installed and documented to be in the right location, at the right depth with the proper bending radius.
- Reduce the threat of third party damage or natural forces by knowing the depth of cover and managing this preventative and protective measure.
- Excellent in deep water crossings, under major highway and environmentally sensitive area HDD projects by providing a detailed permanent record of pipelines actual location.
- Reduced cost, low impact operation can add significant value and confidence to pipeline integrity without any delay during construction operations.
