DrillASSURE- Faroe Islands- Semisub- Conductor response to high current

A client was concerned by conductor fatigue life for a drilling campaign using a semisub off the Faroe Islands

A VIV fatigue assessment of exploration drilling using a sixth generation semi-sub off the Faroe Islands showed base case fatigue life for the conductor system was low. The client was especially concerned about fatigue damage to the conductor as a result of severe sea currents in the area, combined with the effect of using the large sixth generation BOP in relatively shallow water. A riser monitoring system was requested to allow actual motion response of the system to be recorded in real time.
