The equipment used to move conductors from the rig’s V-door, through the derrick, the drill-floor rotary table and the platform guides and into the seabed is crucial. When handling 20–36-in. conductors that may be 12-m long and weigh up to 13 t, safety is paramount. Moreover, this is an operation in which efficient installation can have a major bearing on the project’s economics. An experienced and highly skilled workforce is a precursor to the delivery of a safe and cost-effective operation. CIS personnel are fully qualified and have substantial experience in the field of conductor installation. The company’s projects benefit from their unrivalled knowledge of conductor running and handling equipment
