Abstract

See full text

A drilling marine riser section comprises a main riser pipe with radially extending flanges and multiple auxiliary pipes at least comprising a choke line and a kill line. One or more clamps retain the auxiliary pipes. Further the riser section has buoyancy members. The choke line and the kill line are connected to each of the flanges in a tensile load sharing arrangement, so that—in vertical use orientation of the riser section in a riser string—weight stress is distributed in the main riser pipe and the choke line and the kill line. The buoyancy members form an exterior of the riser section including diametrically opposed and parallel flat bottom and top stacking faces relative to the axis of the main riser pipe, allowing stacking of riser sections in horizontal orientation. The choke line and the kill line are arranged diametrically opposite from one another and between the flat bottom and top stacking faces.
