ABSTRACT:
A marine riser coupling assembly includes bolted flanges (26, 28) with a raised face (30) around the inner edge and a raised face (32) around the outer edge. In the area of the bolt holes (38), there is a recess (34) between the two raised faces around the entire circumference. Bending strain of bolts (42) is thereby reduced.
