Abstract

See full text

A riser clamp (1) made up of several parts and designed to carry a plurality of fluid pipes (11) in parallel with and spaced apart from a surface coated steel riser (10) is shown. The riser (10) itself is designed to be deployed into the sea for communication between a well head at the seabed and a surface vessel. Each riser clamp (1) is designed for frictional, non rotatable fixation to the surface coated riser (10) and is provided with a plurality of pipe saddles (V) to carry the respective fluid pipes (11). The riser clamp (1) has an internal abutment surface (2) made of fiber reinforced composite material which is configured substantially complementary to and designed to bear against the external, surface coated surface of the riser (10). The riser clamp (1) is tightened by means of circumferentially acting tightening means.
