It was first discovered in 1971, but wasn’t developed until 2011 due to its geological complexity and challenging economics. Produced via a self-installing platform (SIP), production ceased in 2018 and the SSCV Thialf was contracted to remove the installation. The 5,000-tonne topside and its four 1,200-tonne legs were removed in a complex lifting operation in August 2019, with F3-FA marking Spirit Energy’s first decommissioning project on a manned platform.
