Under the new alliance between the two companies, Hayward Tyler is designing and fabricating the cooler for the prototype in addition to providing the 2.5-MW subsea motor.
Fuglesangs Subsea, a winner of this year’s OTC Spotlight on New Technology Award, recently signed an agreement with Aker BP, Lundin, and NOV to develop and test a full-scale prototype of what is said to be the world’s most autonomous boosting system.
The prototype will be trialled offshore following extensive factory acceptance testing with the qualified Hayward Tyler penetrator technology adopted to support the subsea deployment of the system.
Both companies claim the development could enable single and multi-phase boosting solutions for a far wider number of subsea wells than can currently be economically accessed using existing technology.
Their goal is for the resultant fully modular Omnirise boosting system to target both “lean” subsea field developments and unmanned platforms.
Its main features are that it is barrier-fluid less and with integrated variable-speed functionality. This is said to reduce the need for topsides equipment on platforms and rigs by 200-500 tons compared to conventional seabed boosting systems.
The system will be qualified as part ofThe Research Council of Norway’s Demo2000 program and is said to be suited to applications such as water treatment and water injection and other single-phase liquid pumping applications.
A future version will also be developed for boosting of multi-phase hydrocarbons, with the functionality is enabled by the Hydromag drive unit, undergoing a separate development program with NOV, Hayward Tyler, Voith Turbo and Innovation Norway.
The Hydromag drive unit combines a magnetic coupling, hydrodynamic torque converter, a fixed-speed induction motor and an embedded cooling and control system.
