Abstract
Disclosed are systems and methods for stabilizing a subsea pipeline such that movements of the pipeline in the axial, lateral and/or vertical directions are restrained. The pipeline is connected to a stabilizing structure generally adjacent to the pipeline using one or more load-bearing members attached to the pipeline and the stabilizing structure at one or more predetermined locations. Also disclosed are systems and methods for monitoring operating parameters of the pipeline over time.
Claims20
A method for stabilizing a subsea pipeline comprising:
- connecting a primary pipeline to a stabilizing structure generally adjacent to the primary pipeline at one or more predetermined locations along the length of the primary pipeline such that movement of the primary pipeline is restrained with respect to the stabilizing structure.
A system for conveying fluids on a seabed, the system comprising:
- a. a primary pipeline located on a seabed;
- b. a stabilizing structure located generally adjacent to the primary pipeline;
- and
- c. at least one load-bearing member having a first end adapted to attach to the primary pipeline and a second end adapted to attach to the stabilizing structure;
- such that when the at least one load-bearing member is attached to the primary pipeline and the stabilizing structure, movement of the primary pipeline is restrained with respect to the stabilizing structure.
