Pipeline Integrity Engineering

At Core Group we believe that effective Integrity Management begins with understanding Asset Owners’ needs and implementing measures that ensure regulatory and code compliance throughout the assets entire life cycle. Our Pipeline Integrity Engineering department work in conjunction with the Easement Management and GIS Teams to provide integrated solutions that become the foundation on which operation and maintenance works are prioritised, planned and executed.

With extensive experience in pipeline construction and operation we offer a full suite of services to ensure the safe and legally compliant operation of our client’s assets.

WORKING AROUND PIPELINES?

GIS Services

Our Geographic Information System (GIS) is a powerful tool that supports our asset integrity management approach. It enables pipeline related datasets to be captured, displayed and analysed against spatial backgrounds such as satellite images, orthophotography, topographical and other online basemaps.

HOW DOES THE TOOL WORK?

Pipeline data from a range of inspection and survey activities such as intelligent pigging, cathodic protection monitoring, pipeline coating surveys, direct assessment, easement activity monitoring etc. can be over-laid and analysed to support effective risk assessment and prioritisation of on-going maintenance plans or remedial works.

Our GIS services provide asset owners and operators with the capability to store, manage and efficiently access large amounts of asset related data to support the safe and efficient management of all assets over their lifetime. Once the pipeline data has been captured in the GIS the client can utilise web-based viewing software and applications to access their pipeline data from any smart device or computer and carry out their own review and analyses as required.

WHAT CAN THE GIS TOOL BE USED FOR?

  • Access to Datasets through Online Maps & Viewers
  • Live Operations Dashboard Data Display
  • Field Data Capture & Management
  • Alignment Sheet Generation
  • Radiation Contours
  • Liquid Spill Analysis
  • Easement Data Management (Permit, Surveillance, Incident)
  • GPS Surveys
  • Urban Encroachment/Class Location Analysis

  • CCO (Critical Contingency Operator)

    The Gas Industry Company (GIC) administers the Gas Governance (Critical Contingency Management Regulations 2008) Regulations. The purpose of the Regulations is to achieve the effective management of critical gas outages and other security of supply contingencies without compromising long-term security of supply.

    The Regulations achieve this principally through the appointment of a Critical Contingency Operator (CCO) which has a range of powers, particularly to curtail gas consumption during critical contingencies. Core Group was appointed as the CCO, effective from 1 March 2014.

    The role of the Critical Contingency Operator includes:

    • Determine and declare the onset of a Critical Contingency
    • Call for load curtailment as required to balance the system
    • Continuously monitor the supply / demand balance and adjust load curtailment directions as necessary and determine when it is safe to terminate a Critical Contingency
    See the official CCO Website for more information on the CCO.
