  1. 3P Services, Germany Basil Hostage The missing link – inspecting the final critical section of a large crude transmission and export system

  2. DGMK-Vortrag 30.04.1999 In-line inspection since 1992 MFL world wide initially specialized on small diameter tools (4“ to 10“) today 3“ to 42“ …

  3. Ocensa‘s offshore pipeline

  4. Ocensa‘s offshore pipeline

  5. Integrity assessment selected by Ocensa Internal inspection tool capable of Detecting corrosion and deformation Anomalies including dents, gouges and grooves

  6. Necessary considerations • Cleaning • Remove internally for old deposits of sands, wax and sediments. • Restrictions identifications • No impacts to crude oil transport program • No receiver trap installed • No environmental impacts • Inspection metal loss with a High Resolution Tool • Sizing and location accuracy. GPS location. Detection of anomalies on welds

  7. Necessary considerations • Identification and location of mechanical anomalies • Identify, locate and size dents,ovality, wrinkles, deformations. • Identify possible defects in the pipe were the intelligent tool could be stuck. • Processing and analyze data • Review the data, identify defects, prioritize and define plan to go forward. • Anomalies assessment according B31G and R Streng • Finding’s repairs . • Data validation and repairs according with the report and priority

  8. Inspection and cleaning technology • Cleaning • Gel • Conventional • BiDi • Inspection • Umbilical • Conventional • BiDi

  9. ILI Background • Contacts with operators with Offshore In Line Inspection experience • In Line inspection vendors • Risk Assessment In Line Inspection Technologies • Technologies Assessment • Risk Assessment for Receiver Trap installation • Facilities required, trap mobilization and installation, environmental impacts • Risk Assessment for Operation • Submarine valves, flow backward, use tanker storage

  10. ILI Background • Risk Assessment Pigging • Quality of cleaning, pigging alternatives evaluation, pigging program design • Discussion about procedures, logistics and equipments required • Operation, transport, control center, maintenance, environmental, Terminal and integrity. • Final Risk Assessment to define best ILI and pigging alternative with all areas.

  11. Selected ILI technology • Bidirectional Tool. • No required receiver trap installation. • High Resolution Tool. • High number and density of sensors, accuracy. • Classification ID/OD discrimination. • Boxing,clustering and interaction analysis.

  12. Selected ILI technology • Metal loss correlation with mechanical anomalies. • Excellent accuracy and probability of detection. • Sizing Accuracy( Manual and Auto) • Anomalies location with (GPS) • Inspection coverage (100%) • Interpretation and assessment of data

  13. Ocensa‘s work scope • Max preparationforcleaning • MFL, GEO and XYZ • Completetrackingandmarkering • Safe navigationnearthe PLEM • = thefullprogram

  14. Project conclusion • Issuestobecovered • Contract • Technical planning • Logistics • Job execution • Data analysis & reporting • Verification • Veryambitious time schedule

  15. Project conclusion • Howcouldthiswork? • OCENSA: large pipelineoperator • 3P Services: smallcontractor, faraway

  16. Answers • Carefultechnologyanalysisanddecisionby OCENSA • Contract: OCENSA respected 3P‘s specificneeds • High flexibilityof 3P Services, sincesmall • OCENSA madesystematicuseof 3P‘s experience • High professional skillsofthe individuals involved
