ABSTRACT:
A protective sleeve protects a riser that extends between a subsea wellhead and a floating vessel. The protective sleeve has less resistance to bending than the riser so as to allow the riser to bend normally due to normal movement of the vessel. The stiffness of the protective sleeve augments the stiffness of the riser only if the acceptable level of bending is exceeded. The protective sleeve is made up of at least three segments that are articulated together to facilitate bending.
