Aquaterra, Plexus Launch HP/HT Riser System
Aquaterra Energy and Plexus Holdings have developed a light weight, dual barrier HP/HT riser system capable of being deployed by a jackup.
The companies said the technology, which is suitable for depths of up to 150 m (492 ft), is a viable and cost-efficient alternative to semisubmersible installation for HP/ HT well operations. The system merges Aquaterra’s HP/ HT riser system and Plexus’ POS-GRIP wellhead engineering technology.
“An inner riser string is installed inside a conventional high pressure riser (HPR) to span the gap between a dry surface BOP and a wet subsea tree. It provides full 20,000- psi capability and utilizes all metal-to-metal gas tight seals on both the external and internal riser string,” ,” Aquaterra said in a news release. “The system also eliminates the issues associated with surface wellhead developments that contain elastomeric seals, particularly those located between the mudline and surface.”
Subsea UK Gears Up To Discuss ROV Technology
ROV engineering and advances, autonomous inspection technology, enhanced data collection and the challenges posed by lower oil prices will be among the topics featured at Subsea UK’s 2016 Underwater Vehicles Conference.
“The global underwater vehicle market is expected to grow significantly over the next five years as operators delve into deeper, harder to reach seas and the demand for enhanced ocean data increases,” said Subsea UK CEO Neil Gordon. “Since the sharp drop in oil prices, underwater robotics have been seen as a key area of development for subsea interventions, as the industry has been forced to consider smarter ways of working, by adopting new techniques and technologies.”
Infield Systems Ltd., Shell, Seatronics, Subsea 7, See- Byte, IMCA, and Ecosse SubseaSystems are among the presenting companies. The conference is set for Sept. 27 at the Aberdeen Exhibition and Conference Center. For more information, visit www.subseauk.com/events.asp.
