Pipeline Riser Conversion 2001
Diver and tenders with guillotine saw
The project required the use of two hydraulic guillotine saws, hydraulic grinders, and impact wrenches. We "fresh headed" the pipeline using a torque connector, then had the associated spool piece measured, manufactured, and installed during a six day period. The subsea portion of the project was completed four days ahead of schedule.
