Abstract
A riser for a subsea well comprises a first riser section that may be similar to conventional risers in design and material specifications. A second riser section comprises a passive fracture section that is specifically designed to shear or fracture under design conditions, such as extreme events (e.g., extreme weather or waves, loss of control of a rig or vessel, a rig or vessel moving from a desired position). The passive fracture section is designed to fracture first to prevent or minimize damage to other well equipment, such as at the seabed.
