摘要： An improved marine riser (12a,12b) is described which has couplings (20,22) with screw-threads for securing marine riser sections together and a carousel mechanism (50) for coupling the auxiliary lines (14) to the marine riser sections (12a,12b) at various locations along the sections to permit the lines (14) to rotate freely relative to the marine riser sections as the sections are rotatably assembled. An improved buoyancy module (110,118) is also described which houses the choke and kill lines (116) in buoyancy module fairing portions (114,120,122) for reducing the effective module diameter and the effect of current and vortex shedding.
