SPOTLIGHT:
VetcoGray SemStar5
™
Our fifth-generation subsea electronics module draws on
field-proven technologies and over 30 years of subsea
experience. Ruggedized to exceed ISO 13628-6 2006
requirements, the radical new design optimizes flexibility,
durability, reliability and obsolescence mitigation. It’s
been critically acclaimed by industry leaders and media
alike, including receipt of an OTC Spotlight on New
Technology Award.
With ambitious expansion plans for the Tordis and Vigdis
fields in the North Sea, Statoil became the first company
in the world to use SemStar5. Although the fields have
produced over 629 million barrels of oil – roughly 300
million more than expected – this upgrade will enable
nearly 400 million more barrels in the next 15 years.
A total of 27 wells were upgraded including subsea control
module retrofits, installation of a new electrical distribution
system, and replacement of topside control systems.
The field was greatly simplified by eliminating many of
the original multiple-vendor control modules and using
SemStar5 instead. The module enables complete
operation from shore, including real-time monitoring
and diagnostics of all seabed equipment. It also
enhances safety and productivity with advanced
sand-monitoring and leak-detection capabilities,
and has the flexibility to integrate more features
in the future.
Aside from being the first SemStar5 installation,
it was also the first major brownfield subsea
controls upgrade in the world.
