A highly tensioned, suspended pipeline (HTSP) which is especially useful in permafrost regions, rugged terrain, and active seismic fault areas. Basically, the pipeline is comprised of segments which are fluidly connected together to form the desired length of the line. Each segment is comprised of a length of tensioned pipeline which extends between two fixed anchors and which is suspended over a plurality of vertical support towers therebetween. The length of pipeline is greater than the distance between the anchors to allow the pipeline to sag significantly between adjacent vertical supports whereby there is no need for expansion loops in the line.

Method of installing a highly tensioned suspended pipeline

A vibration damper includes a suspended mass connected to a pipeline or similar structural member by a support ring and an assembly of interconnected, generally cylindrical damper members formed of an elastomer material suitable to be stressed in shear. The damper assembly is of modular construction so that the damper can be easily tuned to particular frequency and amplitude conditions of different pipes and spans, respectively.
