The Transocean Leader rig is operated by Transocean. The rig was issued with an Acknowledgement of Compliance (AoC) by the PSA in December 2004.  An Acknowledgement of Compliance is a statement from the PSA indicating that an offshore drilling rig is considered to be in compliance with relevant requirements in the petroleum activities regulations.
