1 (IDC) INTEGRATED DATA COLLECTION TECHNOLOGY Presented by: Kevin Pastotnik

2 Definition and Brief History to the Need

3 INTEGRATED DATA COLLECTION TECHNOLOGY What is IDC? IDC is an external assessment tool that performs multiple Indirect testing techniques simultaneously; in a single pass. What drove the need for IDC? Regulations called for 1, 2 or 3 tools depending on inspection cycle Budget and time constraints required for multiple passes using legacy equipment Application and limitations of tools weren t always considered Comprehensive analysis on data couldn t always be performed given number of tools used and limitations on the tool itself

4 Why Were Integrated Surveys Needed? Leakage Cost Cause of Leak Other operator costs:, $261,481, Public/Private property damages amount, $11,827, Other public costs, $13,029, Cost of emergency response phase:, $120,003, Value of operator property damage, $97,580, Cost of environmental remediation, $94,508, Value of product The direct cost of these accidents surpassed $ 600 million. However, not considered was corporate share devaluation that may reach $ billions, as in the April 2010 BP Gulf of Mexico incident.

5 Why Were Integrated Surveys Needed? From 1994 through 2013, there were an additional 941 serious incidents with gas all system type, resulting in 363 fatalities and 1,392 injuries [1] A recent Wall Street Journal review found that there were 1,400 pipeline spills and accidents in the U.S According to the Journal review, four in every five pipeline accidents are discovered by local residents, not the companies that own the pipelines [2] [1] Wikipedia reference to - [2] Alison Sider, Wall Street Journal, Jan. 20, 2014

6 Introduction to the Technology

7 Functionality of IDC IDC Simultaneously Collects: ACCA AC Current Attenuation Survey ACVG AC Voltage Gradient Survey DCVG DC Voltage Gradient Survey CIS Close Interval Survey Sub-meter GPS Mapping Pipe Location and Depth-of-Cover Survey Optional Leak Detection Survey

8 ACCA AC Current Attenuation Survey What is ACCA? A tool that uses an inductive signal to map out simulated current and flow direction How does it work? A transmitter induces simulated current at various adjustable loads. A receiver displays the amount of simulated current pickup and current flow direction What is it used for? Mapping current flow, response and distribution Locating electrolytic and metallic shorts

9 ACVG AC Voltage Gradient Survey What is ACVG? A tool that uses an inductive signal to locate and size coating anomalies How does it work? A transmitter induces a signal that drains at coating anomalies A receiver and probes locate areas where the signal drains, then isolates and sizes anomalies based on signal measurements What is it used for? Locating and sizing coating anomalies ACVG is able to find coating anomalies that can be missed by DCVG

10 DCVG DC Voltage Gradient Survey What is DCVG? A tool that uses interrupted CP current to locate and size coating anomalies How does it work? Existing, or induced, CP current is interrupted The interrupted DC potential is measured where CP collects at the coating anomaly The measured DC IR is used to size coating anomaly What is it used for? Locating and sizing coating anomalies

11 CIS Close Interval Survey What is CIS? A tool that collects pipe-to-soil potential measurements at select intervals to determine cathodic protection levels How does it work? A meter and probes are used to collect DC potentials using wired connections to above ground appurtenances What is it used for? To determine cathodic protection levels Interrupted (On/Off), Static and Native are the most common types of CIS survey. Each survey type is used to determine different criterion specifications are achieved

12 Additional IDC Technologies GPS Mapping Sub-meter accuracy Ability to track access routes and perform quality control on the integrated data Ability to GPS map in areas of high foliage and cover Pipe Location and Depth-of-Cover Survey Pipe location and depth-of-cover integrated into the data stream and used as part of the data analysis Optional Leak Detection Survey Ability to perform regulatory leak detection surveys while GPS mapping areas of concern

13 Advantages of Application

14 IDC ALLOWS FOR 6 OR MORE TOOLS IN A SINGLE PASS ACCA, ACVG, DCVG, CIS, GPS, Leak Detection + Legacy equipment only allows for 1 tool in a single pass significantly increasing the amount of resources and time required to complete a comprehensive survey

15 IDC ALLOWS FOR INTEGRATED EXTERNAL DATA ANALYIS Utilizing the data from all tools allows for complete analysis and a more accurate assessment of risk in areas of concern For Example: ACVG (vs) DCVG coating anomalies CIS trends (vs) coating anomalies CIS potentials (vs) ACCA metallic shorts ACCA metallic shorts (vs) coating anomalies

16 IDC and ILI INTEGRATION Integrating IDC and ILI data allow the user to perform total analysis For Example: ACVG / DCVG coating anomalies (vs) ILI metal loss ACCA current mapping (vs) ILI below grade flange location Pipeline location and DOC (vs) ILI inclination and POI s Historical IDC (vs) historical ILI comparison

17 IDC COST EFFECTIVENESS Reduction in personnel and time required to perform comprehensive survey Manages the risk with dig selections using data from only 1 or 2 tools Every data point and its coordinates are recorded and saved into an all data export which can later be imported into any data stream, or GIS system Every data point can be queried and compared to historical findings

18 IDC QUALITY CONTROL Remotely review data to find additional defects that may have been missed during collection Collects continuous GPS and is able to track the equipment operator throughout the survey Able to set data point extremity notices so the operator can be advised of AOC s in real-time Every data point is collected in sub-meter GPS, reducing the overall footprint of remediation if necessary
