Conductor Installation Services Ltd (CIS), an Acteon company that provides hammer services to install conductors and drive piles, announced that it successfully completed its second conductor installation operation during the last 12 months for a leading 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.
The installation campaign was completed on time, without delay or downtime. Once again, this operator saved time and money as a result of CIS’s efforts on their behalf.
Building on success
Earlier this year, CIS carried out a pile-driving campaign on the same development that was completed 17 hours ahead of schedule. As a result, the operator realized significant cost-savings in terms of reduced equipment rental fees, rig time and labor.
“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.”
The range of services provided by CIS supports the Acteon Group’s commitment to defining subsea services across a range of interconnected disciplines.
