Cause & Consequence
- Moving, flying or falling object
- Change management
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).
