  • Lateral buckling mitigation apparatus, methods and systems for use with subsea conduits
    Patent number: 8721222
    Abstract: Disclosed are systems and methods for controlling lateral deformation and reducing axial displacement, also referred to as walking, of a subsea conduit such as a pipeline for conveying produced hydrocarbon fluids. The systems and methods include the installation of rolling assemblies on the conduit at predetermined locations. The rolling assemblies include elements for forming rolling modules rotatable with respect to the conduit. Also disclosed is a system for monitoring displacement of the conduit over time.
    Type: Grant
