CIS Group installs conductor offshore Malaysia

Offshore staff

GREAT YARMOUTH, England CIS Group (CIS), an Acteon company, has completed a conductor installation campaign offshore Malaysia, which was finished nearly two days ahead of schedule. 

CIS carried out the operation to create a subsea template to form the foundation of a new wellhead platform. The conductors were driven 275 ft (84 m) below the mudline, which required penetrating a mix of dense sand and stiff clay formations.

To ensure a successful outcome, the company supplied the following services and equipment for the operation: 

  • To enhance the driving process, CIS fabricated four 30-in. x 1.5-in. custom-designed standard drive shoes, which were then welded by a reliable third-party supplier to the bottom of the conductor pipe. 
  • Carried out a pre-operation drivability study based on use of the 90 KJ hydraulic hammer. It provided further assurance that the correct equipment had been delivered, and that the drive shoe selected was appropriate for the job.
  • A primary and back-up set of 30-in. handling equipment to assist in running and driving the conductor pipe.

 The program was completed in five months. The company completed the offshore conductor-driving operation in 12 hours.
