Conductor Installation Services Ltd (CIS), an Acteon company that provides hammer services to install conductors and drive piles, has successfully completed its second conductor installation operation during the last 12 months for a North Sea oil and gas operator.

Work was carried out on a major gas development project in the Southern North Sea. CIS installed six 30-inch conductors on the project to form the foundations of six development wells. In addition, CIS supplied all conductor-running services, handling equipment, together with drive shoes that improve driveability by 40%.

Following completion of a comprehensive drive study, CIS crew worked with rig contractor Ensco and the operator to commence the driving operation. CIS worked from the jack-up rig Ensco 80, and used a 90 kJ hydraulic hammer to drive all six conductors to their target depth on the wellhead platform. Conductors were driven as deep as 401 feet from the rig floor to the conductor toe, reaching a depth of 158 feet below the mudline.
