flowlines

Anadarko Petroleum announced on its website on 16 May that it is permanently disconnecting 1-in.-diameter return lines from all vertical wells in Colorado—the same type of pipe that carried odorless gas that fueled a house explosion in Firestone, Colorado.

A methodology is proposed for design of subsea flowlines and risers coupled with a subsea high-integrity pressure protection system (HIPPS) for fields with high shut-in tubing pressure (SITP).

Systematic experimental and modeling approaches to designing a safe operating strategy for a 5-km deepwater-subsea-flowline case study are presented to address unplanned shutdown and restart events for waxy-crude production.
