摘要： A marine riser assembly for use in offshore drilling operations includes a riser pipe, a ball joint in the riser pipe near its lower end, and steel kill and choke lines extending down the riser pipe to points below the ball joint, the kill and choke lines being attached to the riser pipe at points above the ball joint and including helical sections which extend around the ball joint and adjacent portions of the riser pipe through an angle of at least about 360* and at a radial distance from the ball joint and riser pipe sufficient to permit lateral flexing of the ball joint without exceeding the maximum allowable stresses for the helical sections.

摘要： An improvement is disclosed in apparatus of the type including a base anchored to a submerged bottom, an elongated tower provided with a buoyancy chamber near its upper end, and a pivot assembly that connects the tower to the base and permits the tower to sway in response to environmental forces. The improvement resides in a fluid tight, open bottom housing connected to said tower and adapted to enclose the pivot assembly in a bath of a lubricant, regardless of the angle of tower sway.

摘要： Offshore apparatus is disclosed which includes a base, a tower pivotally connected to the base, at least one support member attached to the tower and adapted to slidably support a conductor pipe, and at least one conductor pipe adjacent and substantially parallel to the longitudinal axis of the tower and laterally supported by at least one support member. An articulatable means connects the apparatus to a span of the conductor pipe situated in close proximity to the pivotal connection. This means provides sufficient lateral support to the pipe span to prevent buckling and at the same time controls the configuration of the pipe span as the tower sways to prevent bending stress within the pipe span from attaining a level that will cause the pipe to fail.
