Q: What is a key non-metallic alternative to steel pipes in abrasive service, and what are its challenges?
A: Elastomer-lined pipes and rubber hoses are used in abrasive services like oil sands slurry transport. Challenges include limited wear monitoring capability, localized liner wear at joints, and the potential for unexpected failures without comprehensive inspection-8.
Q: What novel technology is being developed to monitor wear in non-metallic slurry pipes?
A: A novel wear monitoring technology based on Radio Frequency Identification (RFID) is being developed and deployed for these pipelines-8.
Q: What is a critical design consideration for the top connection of an HP/HT riser to a floating vessel?
A: Traditional flex-joints may not be feasible. Instead, a Stress Joint (potentially made with titanium for ultra-deep water) may be required at the top connection-6.
Q: What is the primary focus for conventional onshore pipeline design?
A: Conventional onshore pipeline design generally centers on the need for the pipe to withstand internal pressure-4.
Q: How does the design focus shift for deepwater trunklines?
A: For deepwater pipelines, the focus shifts significantly to the need to withstand external hydrostatic pressure to prevent collapse during installation and service-4.
