Based on the technology developed for the flexible casing joint, Vasshella Subsea Technologies has designed and built a flexible solution for subsea guide posts.
Vasshella Flexible Casing Joint
Vasshella Flexible Casing Joint (VFCJ) is securing the integrity of a Subsea Wellhead System.The flexible HNBR / stainless steel element are compressed by the weight of the 20” casing string and acts as a spring during thermal expansionof the casing during drilling.The VFCJ will also reduce the stress variations on the welds below the Well Head. This secures a massive increase in fatigue lifetime.Introduction of VFCJ with standard Well Heads in 36” conductor will eliminate the need for expensive and complex Ridgid Lock Down systems
