An apparatus is disclosed which provides fluid communication between the inner bore and the annular space in a pipe-in-pipe system. Other embodiments disclose an apparatus which provides fluid communication between adjacent segments of the annular space, between the inner bore or the annular space and an external source in a pipe-in-pipe type system. Methods and systems are disclosed utilizing the various apparatus embodiments to transport well fluids in an offshore or onshore hydrocarbon production operation.

Pipe-in-pipe apparatus, and methods and systems

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.

Lateral buckling mitigation apparatus, methods and systems for use with subsea conduits

Systems and methods are described for controlling axial, lateral and/or vertical movements of subsea pipelines which reduce the need for expensive pipeline anchoring or other mitigation solutions. The pipeline is connected to a stabilizing structure generally adjacent to the pipeline using a plurality of load-bearing members attached to the pipeline and the stabilizing structure at a plurality of predetermined locations. Also described are systems and methods for monitoring operating parameters of the pipeline over time.
