DrillASSURE- Gulf of Mexico- Semisub- Conductor fatigue damage

Pre-drilling analysis of a campaign in the GoM gave a conductor fatigue life of just 8 days.

An operator was embarking on a drilling campaign in the GoM using a semi-submersible vessel in 6000ft
water depth. Analysis carried out before the project had given the conductor a fatigue life of just eight days, identifying the conductor top weld as the fatigue critical location. This led the client to install a standalone monitoring system to measure BOP and conductor movements as well as the overall global response of the riser.
