In May 2006, Songa Offshore signed a nine-month contract with Chevron to use the rig in Australia. A contract was later signed with Santos Ltd., which was originally nine months and was extended to a year and then a year and a half. In 2013, the rig was contracted by Idemitsu Oil and Gas for drilling off Vietnam.
In 2014, Songa Offshore sold the rig to Opus Offshore as a part of the deal creating Songa-Opus joint venture.
