  • Underwater cryogenic pipeline system
    Patent number: 4718459
    Abstract: 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.
