2011 SPE - Electronic logging to improve safety

  1. 1. 1 Using Electronic Shift Logging to Improve Safety Andy Brazier Tel: +44 1492 879813 Brian Pacitti Tel: +44 1224 355260 Martin Sedgwick Tel: Martin.Sedgwick@
  2. 2. Two part presentation 2 1. Companies need to improve critical communication processes, including shift handover 2. Case study from – role of shift logging in preventing process safety incidents Underlying theme – technology is available to assist improvement (e.g. Opralog from Infotechnics)
  3. 3. 3 Is there a link between safety and communication? Is communication hazardous? Did it ever kill anyone?
  4. 4. 4 Deep water drilling in the Gulf of Mexico is: Complex Hazardous At the edge of our technical capabilities The people involved have to know what is going on Day by day Hour by hour Minute by minute
  5. 5. 5 They need to communicate. But… The work for different companies They report to different people They are restricted in what they can say The result is No one has the full picture of what is going on Bad decisions are made
  6. 6. 6 Transferring oil products between sites is: Relatively simple Nothing new Hazardous The people involved have to know what is going on otherwise: They may not know a tank is being filled They won’t know it needs to be monitored It may overflow
  7. 7. 7 And don’t forget: BP Texas City Piper Alpha Bourbon Dolphin Etc…………..
  8. 8. 8 What is the problem? 1. Knowing what to communicate There are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns – the ones we don't know we don't know. 2. Inadequate systems 3. Inappropriate behaviour
  9. 9. 9 What can you do? 1. Tell people they have to communicate 2. Train people to communicate better 3. Specify/guide what has to be communicated 4. Make sure they are communicating 5. Make sure communication is effective 6. Identify problems 7. Drive (continual) improvement I.T. Solutions Making it easy to log information that is then readily accessible to anyone who may need it
  10. 10. What is the problem? Incorrect information given Information misinterpreted No communication 10 All of the above
  11. 11. What can you do? Tell people they have to communicate Train people to communicate better Specify/guide what has to be communicated Make sure they are communicating Make sure communication is effective Identify problems Drive (continual) improvement 11
  12. 12. 12 The problem Shift handover is a complex, error prone activity, performed frequently High risk It can’t be ‘engineered out’ Partly driven by systems and procedures Highly dependent on behaviours of people involved Rarely cited as a root cause of accidents. But is anyone looking for it?
  13. 13. 13 We know there is room for improvement but…. People underestimate its complexity and hence overestimate their ability at shift handover Who has the incentive to put in additional effort? Person finishing their shift – want to go home Person starting their shift – don’t know what they don’t know Managers – rarely present Seems to have fallen into the “too hard” category for many
  14. 14. 14 Looking for another angle Tackling behaviours head on is not easy Log books used at handover contain a wealth of information Could this be used more widely?
  15. 15. 15 Offshore study Copies of a week’s logs 3 ½ kg of paper All hand written Multiple formats Contents reviewed
  16. 16. 16 Information being recorded Human errors Valve ‘inadvertently’ closed, missing parts and information, tasks not complete Minor incidents Small releases, equipment failures Routine tasks 120 operational tasks recorded Solutions to problems Release pressure, manually manipulate valve, use sealing compound
  17. 17. 17 Other studies using data from log books Component reliability1 Hours of operation, failure and repair time Economic operation2 Model of plant breakdown and identification of items critical to system reliability Reliability3 Development of a fault tree used to identify plant modifications References 1 – Moss 1987 2 – Campbell 1987 3 – Galyean et al 1989
  18. 18. 18 Findings from these studies Date from log books could be very useful It is relevant to safety and reliability studies Allows models to be developed Supports expert judgement Difficult to achieve Handwritten Not structured with data collection in mind Concerns about consistency.
  19. 19. 19 Putting these ideas into practice
  20. 20. 20 Maximising the value of data Improving the quality of data To get the full picture, it is usually necessary to have input from more than one area of the business It is useful to be able to consider logged information alongside the relevant ‘hard’ process data Information may be required in different formats for different purposes Supporting the operator in collecting the data Making it as easy as possible Making it very clear what is required Using the data
