Many companies were involved in the incident. Santos, which owned the disused oilfield, hired the Dutch company Fugro to remove the Sinbad rig and the similar Campbell rig nearby.
Fugro secured a construction vessel from Allseas and rope access technicians from AusGroup’s subsidiary MAS.
The two technicians were on the side of the large steel pole, or monopod, which had been cut to allow the platform to be lifted by a crane onto a nearby ship when the platform shifted from unexpectedly and began to sway wildly.
The Sinbad and Campbell platforms were installed in 1993 and have been idle for 15 years since production ceased in 2006.
Santos has been contacted for comment.
