The technical challenges associated with subsea systems continue to increase as developments become increasingly complex: deeper water, longer step outs, higher temperatures and pressures and greater focus on cost control. This added complexity makes inspection and repair more difficult increasing the demand for proven reliable equipment.
Subsea inspection and asset integrity reliability assessment has for many years involved a rolling combination of remotely operated vehicle, towed side scan sonar and diver based inspections. Developments in AUV technology allow these free-swimming devices to collect required inspection data effectively, efficiently and without an umbilical connection to a vessel. AUV deployment has been sucessful, particularly in the area of pipeline free-span data gathering and application. Paul’s discussion will cover these innovative technologies and discuss how the data has been applied for proving integrity. It will also overview other benefits from completed AUV inspections; with real imagery of findings that may not have been discovered with traditional tools.
Adriana will discuss the Subsea Equipment Australia Reliability Joint Industry Project (SEAR JIP). The goal of the collaborative project is to develop a better understanding of the reliability of subsea equipment for use in offshore Australia. The SEAR JIP project provides a unique opportunity for operators to collaborate, sharing technical experiences and lessons learned in order to improve their ability to improve the performance of subsea equipment. The presentation will cover the development of a reliability database, sharing of Lessons Learned and testing programs all aimed at improving reliability.
About the Speakers
Paul Mitchell, Integrity Manager, Quadrant Energy
Paul Mitchell is in his thirtieth year of oil and gas infrastructure integrity management. He moved to Perth in 2006 and has been Integrity Manager for Quadrant Energy (and before that Apache) since 2009. His early career with Penspen Limited saw him based throughout the UK, the Middle East and working on every continent except South America at some time. Responsible for all Quadrant Energy pressure equipment, structures and other fixed assets; pipeline integrity remains his original passion.
Adriana Botto, Principal Engineer Subsea Integrity, Wood Group
Adriana has 15 years of experience working with integrity management of subsea systems. She is a principal engineer working for Wood Group since 2006 and Adriana played different roles over the years working in Rio de Janeiro, Houston and Perth.
