Description of Process: 

Integrity management of barricaded areas to identify structural deterioration.

Description of Incident: 

A section of guardrail weighing 55kgs fell 20m from a long-term disused and hard barriered crane pedestal perimeter walkway to a deck walkway directly below.

Good Practice Guidance: 

Consider the following in areas that have been hard barriered off and have limited or no access:

  • Are uninspected areas on your facility recorded on work orders to ensure that risks can be quantified or assessed?
  • Are all structural elements on your facility identified on engineering and/or structural drawings so that they remain visible for assessment and planning as part of topside structural inspection requirements and priorities.
  • Do your DROP Surveys cross-check actual platform layout against controlled drawings, so gaps / omissions are recorded and drawings are updated?

The following reflective questions could be used as part of any discussion during the planning process for integrity management and inspection programs:

  • Who is responsible for planning “hard barriered” area inspections where access is restricted or prohibited?
  • How often are they undertaken?
  • How do you monitor the number of areas that are subject to long term “hard barrier” restrictions?
  • How are you assuring that your platform layout drawings are up to date and that nothing is missing from them? (NOTE:  These are the controlled drawings that Topsides Structural Inspection use to plan and prioritise their inspection programs; if they are wrong or have items missing, those items will be not be inspected).
