A structural reinforcement system for a tubular member, comprising: a carbon fiber shell attached to the tubular member with adhesive, wherein the carbon fiber shell comprises a carbon fiber fabric sandwiched between non-carbon bidirectional fabric, wherein the carbon fiber fabric is largely unidirectional along the y-axis along the tubular member; a unidirectional or biaxial fiber reinforced polymer hoop or helical wrap connected to the carbon fiber shell, wherein the fibers of the hoop wrap are largely unidirectionally oriented in the hoop direction; and optionally a protective wrap or coating around the system is provided.
