Abstract
Abstract An anchor support for supporting a pipeline above the ground has a self-aligning support saddle that allows the pipeline to orient itself on the anchor support during construction to relieve stresses in the pipeline and to allow for variations from nominal pipeline elevation and angulation relative to the ground. The anchor support normally fixes the pipeline's position relative to the ground but also allows relative movement between the support and the pipeline upon occurrence of a seismic disturbance or other disturbance that would cause a dislocation of the pipeline and/or anchor support from its nominal position. The self-aligning support saddle, which includes a ball and socket connection for allowing the pipeline to orient itself over the saddle, is fastened to a shiftable subassembly that rests on a stationary base assembly affixed to one or more ground engaging vertical support members. After the pipeline is aligned, the ball and socket can be permanently interconnected to restrain any further movement of the pipeline relative to the shiftable subassembly.

Claim 1
Independent Claim
306 words
A method for interconnecting a continuous section of an aboveground pipeline composed of sections of pipeline rigidly affixed to one another and a series of ground support members comprising the steps of: mounting a first member having a recess in a circular opening on one of said series of ground support members, and orienting said first member in an upright direction so that the axis of revolution of said opening intersects the path of said pipeline over said one of said series of ground support members, slidably mounting a second member having a spherically shaped surface portion on said pipeline, said spherically shaped surface portion having a radius greater than the radius on said opening in said first member, raising the continuous section of pipeline, positioning said pipeline over said one of said series of ground support members and locating said second member along said pipeline so as to orient said spherically shaped surface portion for partial insertion into said recess in said first member, affixing said second member to said pipeline, interengaging said spherically shaped surface portion of said second member with said recess in said first member while allowing substantially free movement of said second member relative to said first member about said first member's transverse, longitudinal and vertical axes relative to the path of said pipeline over said one of said serie of ground support members as said pipeline rests on said first and second members and orients itself relative to said one of said series of ground support members, relieving substantially all torsional and bending stresses imposed on said pipeline by allowing said second member to substantially freely self-align itself in said first member as said pipeline is raised and positioned over subsequent ground support members, and permanently affixing said first and second members to each other after said pipeline is aligned.

Claim 3
Dependent Claim
29 words
The method of claim 1 wherein said first member is permanently affixed to said second member by welding the interengaging portions of said first member and said second member.
Claim 4
Independent Claim
317 words
A method for interconnecting a continuous section of an aboveground pipeline composed of sections of pipeline rigidly affixed to one another and a series of ground support members comprising the steps of: mounting one of a first member having a recess with a circular opening and a second member having a spherically shaped surface portion on one of said series of ground support members, said spherically shaped surface portion having a radius greater than the radius of said opening, slidably mounting the other of said first and second members on said pipeline, positioning said first member in an upright direction so that the axis of revolution of said circular opening intersects the path of said pipeline over said one of said series of ground support members, raising the continuous section of pipeline, positioning said pipeline over said one of said series of ground support members and locating the member slidably mounted on said pipeline so as to orient said spherically shaped surface portion for partial insertion into said recess in said first member, affixing said member mounted on said pipeline to said pipeline, interengaging said spherically shaped surface portion of said second member with said recess in said first member while allowing substantially free movement of said second member relative to said first member about said first member's transverse, longitudinal and vertical axes relative to the path of said pipeline over said one of said series of ground support members as said pipeline rests on said first and second members and orients itself relative to said one of said series of ground support members, relieving substantially all torsional and bending stresses imposed on said pipeline by allowing said second member to substantially freely self-align itself in said first member as said pipeline is raised and positioned over subsequent ground support members, and permanently affixing said first and second members to each other after said pipeline is aligned.

A method for interconnecting a continuous section of an aboveground pipeline composed of sections of pipeline rigidly affixed to one another and a series of ground support members comprising the steps of: mounting one of a first member having a recess with a circular opening and a second member having a spherically shaped surface portion on one of said series of ground support members, said spherically shaped surface portion having a radius greater than the radius of said opening, slidably mounting the other of said first and second members on said pipeline, positioning said first member in an upright direction so that the axis of revolution of said circular opening intersects the path of said pipeline over said one of said series of ground support members, raising the continuous section of pipeline, positioning said pipeline over said one of said series of ground support members and locating the member slidably mounted on said pipeline so as to orient said spherically shaped surface portion for partial insertion into said recess in said first member, affixing said member mounted on said pipeline to said pipeline, interengaging said spherically shaped surface portion of said second member with said recess in said first member while allowing substantially free movement of said second member relative to said first member about said first member's transverse, longitudinal and vertical axes relative to the path of said pipeline over said one of said series of ground support members as said pipeline rests on said first and second members and orients itself relative to said one of said series of ground support members, relieving substantially all torsional and bending stresses imposed on said pipeline by allowing said second member to substantially freely self-align itself in said first member as said pipeline is raised and positioned over subsequent ground support members, and permanently affixing said first and second members to each other after said pipeline is aligned.
