1 Real Time Monitoring (RTM) Workshop Production Panel Representative Marathon Oil Company Apr Houston

2 Bio Chris Hall Instrument & Control Technical Authority With Marathon Oil for 10 plus years Responsibility for Marathon Oil s facilities and third party operated assets globally, both onshore and offshore, from the field instrument, control system and machinery integration perspectives. BEng (Hons) Instrumentation & Control, CEng, and FInstMC 2

3 Introduction Single offshore production platform Ewing Bank (Lobster) 20 year old technology/facility Two subsea tie-backs more recent technology ; Green Canyon 244 (Droshky) tied back to Green Canyon 64 (Bullwinkle) Droshky has an offshore full-time operator Garden Banks 515 (Ozona) tied back to Garden Banks 426 (Auger) Ozona is now past end of life and is currently undergoing decommissioning 3

4 Marathon Oil s Production RTM Capabilities Ewing Bank s control system is based around GE Fanuc Plc s and Wonderware SCADA package Remote Operations capability exists, but last used 10+ years ago for operating facility during hurricane evacuation (only used once). Currently not active. RTM capability exists, but not 24/7. More often used to provide remote process diagnostic support Viewing capability provides onshore with extended functionality to replicate exactly what offshore operators can view 4

11 Marathon Oil s answers to BSEE s specific questions Does your company use real-time monitoring for its offshore operations? For production operations, no 24/7 monitoring through RTM Center. Not cost effective due to: Aged technology employed on installation Available bandwidth for installation No recognizable gain for operator If yes, what are the critical operations and specific parameters that your company monitors? None for production operations. (RTM data stream used to monitor emergency generator conditions during hurricane evacuation) Are there specific criteria or risk thresholds that your company uses to prompt real-time monitoring requirements No Does your company rely on any automation and predictive software in real-time monitoring? Not in our GOM Production operations. Elsewhere in our global portfolio we have capability to utilize, such as machinery monitoring What role could automation and predictive software tools play in real-time monitoring? Earlier detection and notification of process envelope excursions, or machinery failure 11

12 Marathon Oil s answers to BSEE s specific questions Condition-based monitoring is viewed by BSEE as monitoring the operating condition of critical equipment and using any generated data to predict and proactively intervene when needed. As such, what role could condition-based monitoring play in real-time monitoring? CBM, used in conjunction with predictive software models may enhance an organization s response to possible problems prior to occurrence, e.g. equipment bearing failure. This can provide the operator with capability to schedule support/maintenance on a just in time basis, preceding actual equipment failure, and re-schedule production capabilities accordingly Describe how operating equipment using condition-based monitoring could be tailored and/or used for real-time monitoring. Using RTM data streaming, organizations could publish specific data on a html page/basis, providing BSEE capability of viewing/archiving specific data as they see fit. Marathon Oil considers that there is the possibility that available/provided data would not be able to be digested in real time to make the efforts of the operator to provide data, useful. 12

13 Marathon Oil s perspective on BSEE s RTM use Positive Considerations Removing BSEE inspectors (observers) from hazardous installations and associated helicopter flights. Marathon Oil believes RTM should not preclude on-site inspections. Capability of BSEE SMEs monitoring many companies and installations activities from a single location. Will there be sufficient BSEE SMEs available to review multiple company RTM operations? Possible earlier prediction of incidents arising? Operators currently have external website that PSS data is entered in for regulatory tracking. BSEE Inspectors have viewing capability to review this data before coming on facility for annual inspections (E-Inspection). Is this capability being used as effectively as it could be? 13

14 Marathon Oil s perspective on BSEE s RTM use Constraints Cyber security issues for companies sharing the data Companies only wanting to provide BSEE with a subset of data and not everything that is available Intellectual property rights - how these are impinged by sharing of information Bandwidth and weather limitations Perceived safety gain Marathon Oil would encourage BSEE to ensure RTM efforts address the spectrum of installations in the Offshore Continental Shelf and the true value added, particularly for production operations. Many facilities are not equipped to facilitate RTM What unintended consequences could evolve 14
