Case Study: Subsea Conductor Running in Strong Currents

Subsea conductor running in strong currents

AS Mosley was recently commissioned to determine safe operating sea state limits for a complex drilling operation, using a 30”conductor, deep (1200m) in the Norwegian Sea.

Undertaking a VIV assessment, strength assessment, and an irregular wave fatigue assessment, allowed us to advise the client to limit the sea state to 4m, which would ensure neither the HWDP nor conductor would exceed their allowable bending stress. This gave them the confidence they needed to proceed, knowing their boundaries and ensuring a safe operation.
