Abstract: Subsea well intervention in deep water is generally being conducted from Mobile Offshore Drilling Units, using conventional drilling risers. A new idea is to replace the conventional riser by a Spoolable Compliant Guide (SCG) which could be installed on a smaller vessel, which would increase flexibility and reduce cost. After installation, this system consists of a pipe-in-pipe system in an elongated S-shape. During operation, this inner pipe is tensioned which compresses the outer pipe due to geometric interaction. The here presented tests focus specifically on how the interradial gap between the two pipes and the bending angle affects the load transfer between them. Results have shown that the magnitude of the transferred load does not change for the tested inclination angles. The outer pipe's axial compression is independent of the interradial gap, whereas its local moment could be determined as a function of load and gap.
