• Human factors analysis of systems for evacuation, escape and rescue

    2007 - Gas, offshore

    Following a major incident on an offshore platform the client identified a number of human errors that had occurred during evacuation, escape and rescue.

    Andy was asked to carry out a human factors analysis of the systems in place, taking into account the events that occurred during this incident. He visited the platform in order to observe arrangements and talk to key personnel. He then completed a task and error analysis. From this Andy made a number of recommendations for improving procedures, training and equipment arrangements.

  • Human factors engineering during Front End Engineering Design (FEED) of an offshore module.

    2012 - Offshore Oil

    Andy was tasked with leading Human Factors Engineering (HFE) studies including critical task identification, task analysis and valve criticality analysis for a new offshore module. The project was relatively early in its design lifecycle and the principles of HFE were very new to the company.  This meant that Andy's role went beyond simple facilitation because he had to explain objectives and methods to participants in some detail.  However, the studies were very effective at identifying potential human factors issues that had to be considered during detailed design.  One of the main successes of this project was that it provided a constructive forum for engineers, operations and maintenance technicians, and personnel from the design contractor to come together to share knowledge and experience.  l

  • Human factors in a HAZOP


    2008 - Gas, offshore

    The client was designing a new gas production platform. Andy was asked to attend a Hazard and Operability (HAZOP) review to ensure human factors was given appropriate attention. His input ensured that human errors and risk controls were considered from a human factors perspective rather than purely engineering custom and practice.

  • Human factors review of bow ties supporting an offshore safety case

    2014 - Offshore gas

    The client had completed a number of bow tie analyses in support of their safety case.  Andy was asked to review these to identify any significant human factors issues.  He reviewed the barriers in order to determine which would be considered safety critical tasks or safety critical activities; and made recommendations about how the adequacy of these barriers could be ensured.

  • Review of control room arrangements

    2006 - Gas, offshore

    Andy was asked to return to the platform approximately one year after his initial review, to evaluate subsequent changes. He found that a number of his previous recommendations had been implemented, and had been received favourably by both operators and management. Andy to identified some further opportunities to improve, challenging some custom and practice that could potentially introduce risk. He was able to make a number of recommendations to further improve the control room that would ultimately contribute to safely reducing manning levels.

  • Review of control room arrangements


    2005 - Gas, offshore

    The original arrangement on the offshore complex included two control rooms. The client had recently changed this to have the two operators in the same room. Andy was required to evaluate the impact of this change and to determine whether it would be possible for one operator to operate the whole complex. This involved a visit offshore and a two day workshop with personnel. The HSE staffing methodology was used as the basis for the evaluation. Andy's conclusions were that the completed changes were largely satisfactory, but that further changes to alarm systems and layout of the control room were required before any down manning could be considered to ensure the lone operator was not overly distracted be events.

  • Review of human factors following detailed design

    2007 - Gas, offshore

    Three offshore gas platforms had been designed and were in the early stages of construction. Previously, during Front End Engineering Design (FEED) a preliminary human factors engineering analysis had been carried out using Shell's Design and Engineering Practices (DEP).

    Andy was asked to carry out a human factors review at the end of detailed design. This involved a three day workshop attended by representatives of the design contractors and the future operating company during which the key systems and critical tasks were identified and analysed. Andy's report confirmed adherence to the DEP and other good practice; and recommended a number of actions to improve the design.

  • Thorough review of an offshore safety case

    2014 - Offshore oil

    Andy was tasked with completing a human factors assessment as part of the company’s five yearly Safety Case Thorough Review.   He did this by comparing the content of the Safety Case and underlying systems and procedures with latest standards and guidelines.  Key topics included procedures, training and competence, supervision and management, and control room design.  He made two sets of recommendations.  The first was how the company could improve the way it manages human factors and the second how the Safety Case should be updated to improve coverage of human factors.  In this case it was found that the company had a number of significant gaps and Andy was able to help the company to prioritise actions to improve.
