Statoil has teamed-up with a consortium involved in developing a joint industry project (JIP) expected to deliver cheap, light, and strong subsea boosting pumps.
Other participants in the consortium include Aker BP, Lundin, and National Oilwell Varco.
Fuglesangs Subsea operates as the project manager for the DEMO2000 JIP.
The Fuglesangs Subsea Omnirise single-phase booster is expected to hit markets by early 2019.
Fuglesangs Subsea CEO Alexander Fuglesang said: “This project has the potential to deliver improvements in all three areas: cost, weight, and reliability.”
The JIP eliminated the mechanical shaft seal, which is claimed to be the source of 70% of subsea pump failures.
In a statement, Fuglesangs Subsea said: “Dynamic shaft seals not only fail all too frequently, they also require a constant flow of so-called barrier fluid, supplied by topside hydraulic equipment and delivered through umbilical lines that can stretch over many kilometres.
“Traditional variable speed drives also add considerable weight and volume topside, with projected subsea versions looking equally as bulky.”
Through the Omnirise system, the JIP intends to use a Hydromag Drive Unit, which comprises a combination of a fixed low-speed subsea electric motor, a variable-speed torque converter, and high magnetic coupling.
Fuglesang added: “The improvements deliver benefits throughout the system, from eliminating the weakest link and reducing topside and subsea equipment, to enabling cost-effective, standardised, and highly modular boosting units.”
Based on estimates, Omnirise is expected to offer savings of Nkr150m ($18.6m) on a single-well boosting installation instead of conventional boosting systems.
According to Fuglesangs Subsea, Omnirise can be installed as a fully subsea solution when it is combined with a Seabox water filtration system.
