CIS have successfully completed a number of conductor installations in the Southern North Sea from their operating base in Great Yarmouth. These have included the installation of 36inch x 2inch jacket docking piles through slots in a drilling template and the batch setting of three 30inch x 1inch conductors utilising CIS designed and supplied Deep Penetration Drive Shoes.
Breakout Services for Large Diameter Pipe
Manufacturer ABB Vetco Gray had accumulated nine conductor landing strings in its yard in Great Yarmouth. Using its large-diameter breakout system, CIS broke out nine 30-in., 1-in. wall thickness RL-4 connections in one day. This was a highly cost-effective solution for the customer.
One of the major advantages of using the CIS Breakout Service is the HSE aspect: The heavy duty equipment operated by CIS is controlled at a safe distance from the breakout rig ensuring that no personnel are exposed to risk in the event of a tool failure.
