An underwater cryogenic pipeline system comprising an insulated underwater pipeline in an integral open frame is disclosed. The pipeline is anchored to the frame at a plurality of spaced apart locations. Bellows-type expansion joints between the pipe anchors compensate for contraction in the pipeline. The frame, which is anchored to the soil at at least one location, resists axial forces in the system and wave and current loadings. The system is preferably fabricated in modules and assembled on site.

An underwater cryogenic pipeline system comprising: at least one pipeline for cryogenic fluid including a high nickel content steel inner pipe for carrying the cryogenic fluid, an outer jacket around the inner pipe defining an annular space therebetween and insulation in the annular space; an elongate open frame adapted to be laid underwater for supporting the pipeline and resisting forces on the pipeline; a plurality of pipe anchors attached to the pipeline and to the frame at a plurality of locations to transfer axial forces in the inner pipe to the frame; and at least one ground anchor attached to the frame for transmitting axial forces in the frame to the soil or sea bed.
