Abstract: A bending restrictor assembly has a pipeline section, a first pipe section affixed to the pipeline section overlying the outer diameter of the pipeline section, a second pipe section affixed to the pipeline in spaced relation to the first pipe section and overlying the outer diameter of the pipeline section, a first collar element having at least a portion positioned between the first and second pipe sections in which the portion overlies the outer diameter of the pipeline section, a second collar element having at least a portion positioned between the first and second pipe sections in which the portion overlies the outer diameter of the pipeline section, and at least one stop member cooperative at the first and second collar elements so as to limit the relative movement of the first and second collar elements so as to limit the bending of the pipeline section.

Abstract: A bending restrictor assembly has a pipeline section, a first overlying pipe section having a wall overlying a portion of the pipeline section at one end thereof, a second overlying pipe section having a wall overlying another portion of the pipeline section at an opposite end thereof, and a plurality of cylindrical members overlying the pipeline section between the first and second overlying pipe sections. The first and second overlying pipe sections extend outwardly beyond the respective ends of the pipeline section. The bending restrictor assembly achieves a permanent bend and restricts ovality of a subsea pipe.

Abstract: A bending restrictor assembly for use with a pipeline section has a sleeve affixed to the pipeline section, an outer collar slidably positioned relative to and over the sleeve, and an inner collar slidably positioned relative to an interior of the outer collar. The inner collar in spaced longitudinal relation to an end of the sleeve. The inner and outer collars are slidable relative to a bending of the pipeline section. A series of holes and keyways are formed in the inner and outer collars. Pins are inserted into corresponding holes and keyways so as to correspond to a limit of the bending radius of the pipeline section.
