Abstract: This paper explores the latest development in above-ground waterflood pipe anchors currently being used on the SOHIO operated portion of the Prudhoe Bay Oil Field. The objective of the new design was to develop an alternate anchor for waterflood pipelines which has the same insulating properties as a piece of straight insulated pipe. This anchor, designated Tension Member Insulated (TMI) anchor by SOHIO, carries all axial loads by metal to metal connections while maintaining high thermal properties. The TMI anchor replaces the foam anchors used previously. Cracking of the foam in the existing foam anchors was a contributing factor in the development of the new anchor.
