CIS Finalizes Conductor Installation Ops in North Sea
Conductor Installation Services (CIS), an Acteon company, has 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 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.
Following completion of a drive study, CIS crew worked with rig contractor Ensco and the operator to start 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.
“We have worked on behalf of this operator in the North Sea many times,” said Andy Penman, Group Managing Director of CIS. “Once again, the driving operation went to plan. The investment in planning, detailed drive study, technology employed and experience of our installation team contributed a great deal. The positive relationships that we share with Ensco and the operator mean that we come with a winning attitude and commitment to achieving success on every job we undertake, and this operation was no exception.”
