© Kingston Systems 2014 – API Cybersecurity Conference Managing Software on Mobile Offshore Drilling Units (MODUs) Learning to Walk Before you Run

© Kingston Systems Discussion Scope Objective –Gain a perspective on where Drilling Contractors are in their ability to apply software maintenance best practices to MODU Programmable Logic Controller (PLC) Control Systems Questions –Where are they now?  Review real world examples –Practical next steps? Perspective –Kingston Systems performs control systems design review, acceptance testing and security threat analysis audits on rigs and platforms

Where are Drilling Contractors Remember “Walk before you Run”?

© Kingston Systems Case Studies Regression: After commissioning the Top Drive(TD) we found the Vendor editing the Step7 code. When asked if he was pre-testing, post testing, archiving and checking with Base regarding the changes. “Yes Yes Yes” he responded. Next day, the TD started auto-rotating and speeding up to alarming rates. With no backup, it took 1 week to return to normal; the full commissioning test was never repeated.

© Kingston Systems Case Studies Work Authorization: On a rig with a notorious history of downtime. We were invited to investigate system stability (IE: why are we having so many problems?). We and observed the Chief Electrical Superintendent and the ET editing Step7 code on the Draw works.

© Kingston Systems Case Studies Virus on New Build A brand new build drillship on its way from the yard. The Acoustic System*had a virus that resulted in a cascade of window pop-ups as it tried to find an internet connection. This cascade made the system inoperable. It shut the Dynamic Positioning capability down for 18 days *Windows PC HMI was impacted not the PLC or motor controls

© Kingston Systems Where are Drilling Contractors Other Complications –Rental nature of rigs & Mobile nature of business –Corporate to Rig disconnect –Multiple Vendors & Systems –No single list of software assets on a rig

© Kingston Systems Where are Drilling Contractors Where are Drilling Contractors in their ability to apply software maintenance best practices to MODU PLC Control Systems? –Virtually non-existent or arguably in infancy –So what are practical next steps?

© Kingston Systems Tools Available 1988 Piper Alpha A positive outcome = improved implementation of Permit to Work (PTW) But Software is not in scope – Why not?

© Kingston Systems What to do about It Implement Basic Software Management of Change 1.Corporate Support & Industry Direction 2.Change Authorization Process –Software Change Request –Include Permit to Work (PTW) 3.Software Registry to track assets 4.Post Change Testing Enhance understanding of Software scope and impact !

Easier Said than Done We have yet to see a MODU that is compliant with their own process and tools

© Kingston Systems Wrap Up MODUs are not managing their control software very well Implications for security are apparent Basic Software Management of Change practices are needed
