Offshore Technology Conference 2015

Tubular Bells' subsea umbilical, riser and flowline architecture lies 4,300 ft. below surface.At the Offshore Technology Conference in Houston, representatives from Hess Corporation will discuss the HP/HT design challenges associated with deepwater fields, including Tubular Bells in the Gulf of Mexico. Some key challenges include large axial expansion, rogue buckling, axial creep, and low-cycle fatigue.


“As subsea technology continues to develop, the ability to produce flowline designs that are able to not only operate in high pressure and high temperature environments, but also provide a safe and reliable solution is imperative,” said Tor Gavem, Manager, Subsea Development at Hess.

Key discussion points for the team’s presentation on May 6 at 9:30 a.m. include how the team optimized various design components in order to accommodate small variations in the input parameters. They will also discuss the results derived from the teams’ comparison of its numerical prediction, and the data acquired from the field observations.

Authors of the presentation paper Critical HP/HT Flowline Design Challenges Associated With Deepwater are: Tor Gavem, Hess; Amitabh Kumar, INTECSEA ; Vijaykumar Panga, INTECSEA; Mike Stratton, Hess, and Jason J. Harry, Hess. 

OTC 2015 technical papers are available on CD and electronic copy to use as a reference tool after the conference. Proceedings are available for purchase on-site in the NRG Center Lobby D on level 1 and in the NRG Arena registration area. For more information about OTC 2015, go to http://2015.otcnet.org.
