Patent ID: 8783630

Claim:
A riser clamp to carry fluid pipes in parallel with and spaced apart from an external surface coated steel riser providing communication between a well head at a seabed and a surface vessel, the riser clamp comprising: a pair of halves for frictional, non-rotatable fixation to the external surface coated steel riser; the pair of halves having an external facing surface and an internal abutment surface made of a fiber reinforced composite material to circumferentially bear against the external surface coated steel riser; the pair of halves having radially outward projecting first and second flanges; a pipe saddle located between the first and second flanges and extending radially outward from the external facing surface to a first saddle recess to carry a first fluid pipe spaced radially apart from the external surface coated steel riser; a first clamp connected with the pipe saddle to secure the first fluid pipe in the first saddle recess; and an orbital strap to be positioned circumferentially about the pair of halves and located on the external facing surface between the pipe saddle and one of the first flange and the second flange, the orbital strap to circumferentially act on the pair of halves and thereby non-rotatably fix the pair of havles to the extenral surface coated steel riser in response to tensioning the orbital strap.
