flowlines

The contractor will install flexible pipe and subsea structures on the field in Block 17 offshore Angola.  

The Cypre offshore gas project announcement comes the day after the energy company renewed its supply contract with the country’s national gas company.

Contractor, operators will work to bring thermoplastic composite pipe (TCP) flowline and riser technology to market.

Two contracts awarded for flowlines and wellheads at ADNOC’s Abu Dhabi oil fields are expected to be completed in 5 years. A third contract to develop a bypass system for its Jebel Dhanna and Fujairah terminals is expected to be completed in 30 months.

As operators rely on longer subsea tiebacks, an upward trend in the number of plugs caused by paraffins and hydrates has been seen. New prevention and remediation methods are discussed to help solve these challenges.

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.
