The Power of Safety
Our energy-industry experts supported Woodside Energy in the safe removal of a riser turret mooring (RTM) offshore of Western Australia. The 2,500-metric-ton RTM previously connected the Nganhurra floating production storage and off-loading facility (FPSO) to risers carrying oil for processing. After decommissioning the FPSO, Woodside began plans to remove the RTM.
Removal activities required a regulator-approved safety case to be in place. For nine months, Vice President Joanne Tarleton spent part of each week in Woodside’s offices, working side-by-side with their team to examine the planned removal activities, evaluate potential risk to workers, implement appropriate controls as necessary and ensure proper documentation of safety related decisions.
We brought together all the information and all the people and got input from the workforce, project team and operators, and all of this was incorporated into the final safety case.
Joanne also conducted workshops with project team members, including Heerema Marine Contractors, the operators of the heavy-lift vessel that would be used for the work. The goal was to learn about their operating procedures – especially those relating to transferring workers between the vessel and the RTM – and identify all potential hazards.
