CIS installs two conductors offshore Australia

Offshore staff

GREAT YARMOUTH, UK – Acteon’s Conductor Installation Services (CIS) has installed directional conductors for two wells offshore Australia.

CIS engineers assessed the angles required so that the conductors would be appropriately offset. The company also customized deviated drive shoes for the conductors: two for the wells and one as a back-up. The directional drive shoes were welded to the conductor pup joints at the CIS Asia Pacific Region base in Singapore.

Working from the Seadrill West Telesto jackup rig, CIS used a 150-kJ hydraulic hammer to install the conductors safely, driving them approximately 126 m (413 ft) subsea and a further 117 m (384 ft) below the mudline to their respective target depths. The total length of each conductor was 243 m (797 ft). The company completed the entire offshore operation in three days.

The platform was live during installation so CIS used a cold cutter system to cut the conductors to the correct height and the required bevel in order to prepare them for receiving the respective wellheads.

Neither the operator nor the location were named.
