The design approach minimises the riser steel weight and In recent years new riser arrangements have been conceived to buoyancy requirements and achieves an optimum dynamic meet the challenge of deep water, offering significant commerresponse through an efficient structural design and buoyancy cial and technical advantages over conventional riser systems. distribution. This maximises riser flexibility and minimises These new riser systems utilize steel pipe which has a relatively hydrodynamic wave loading.
