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.
