Transocean Leader Receives AoC from Norway's PSA

On December 16, 2004, the Transocean Leader received the Petroleum Safety Authority Norway's Acknowledgement of Compliance (AoC).

Transocean Leader is a semisubmersible mobile drilling rig owned and operated by Transocean.

It was delivered in 1987 from Hyundai Heavy Industries in Korea. Up until December 2003, the rig was engaged in operations on the British Shelf. Since then, the rig has been upgraded during a stay at the workshop in Olen.

The Transocean Leader is currently on assignment for A/S Norske Shell to carry out exploration drilling on Haltenbanken.

During the consideration process, we conducted audit activities within most disciplines on the rig.

The Transocean Leader was evaluated in relation to relevant regulatory requirements and relevant parts of Transocean's management system for the type of activity that may be conducted with the rig.

Including this AoC, a total of 24 Acknowledgements of Compliance have been issued so far.
