Pipeline Surveys

GIS & Pipeline Integrity Management

Determination of physical locations related to structural integrity issues, are a part of any pipeline operator’s basic risk assessment plan. Locating defects in the field may present a variety of issues, including intervention costs and response times. Managing data and interpreting true locations are key requirements to ‘finding & fixing’ these types of pipeline issues. The physical properties of a pipeline are not a sole reason for concern, but the physical surroundings are equally important, due to land changes. Inspection and monitoring surveys may be performed to increase and support better management solutions. GIS presentation of inspection reports or survey data are supported by subject integration.

Fastrack engineering has practical experience during successful pipeline shut-down periods, of major river crossing replacement and landslide avoidance projects, utilizing open-cut and Horizontal Directional Drilling techniques.

Pipeline Bending Schedules and Field Bending

Preparation of bending schedules and field bending are integrated with pipeline construction activities. Optimum route selection and economic field bending reduce overall construction cost.

Buried thermally insulated pipelines involve a requirement for advanced bending information, depending on field bending techniques. Naturally flexed pipeline bends can be calculated to suit right-of-way ground profiles.

Precisely any cross country pipeline can be engineered in advance, satisfying all design and construction criteria prior to field work. Integrating this process into construction management is a key factor to overall cost saving.

Right-of-Way engineering identifies additional necessary land requirements, whilst providing a safe and efficient work space.

Pre Construction & As-Built Survey

Records of a pipeline construction process are not limited to the physical position of a pipeline. Pre construction, operational and maintenance data, may also be included within a pipeline as-built database. Historically this subject was overlooked in the past, having less regulatory significance than today. Whilst data aquisition remains a survey function, GIS has interactive analysis capabilities to enhance as-built data layers together with pre or post construction activities. As-built alignment drawings may be replaced by GIS database systems in the future.
