Abstract: A support system (12; 12′) for providing horizontal support to a riser (32) extending downward from a cantilever (18) along a well centre and into a body of water comprising a riser interface (48; 48′) and a tether arrangement (50; 50′). The support system (12; 12′) is configured to permit asymmetric placement of the riser interface (48; 48′) relative to the cantilever (18).
