We are also working on edge analytics and storage, building in abilities to perform analytics close to the source of the data and to store both raw data and results for an extended period of time.”

Brekke says industry-standard based integration with top- side systems is very important. This enables interoperability between systems from different vendors and enables use of automation standards on the seabed. “This saves CAPEX and

OPEX,” he says.

“This approach also enhances liberation of data for optimi- zation of production and maintenance. This is growing even more important, and our Subsea DigiGRID system is de- signed to do this very ef? ciently. The Subsea DigiGRID can interface a topside controller on a hard real-time standard au- tomation protocol and, at the same time, from the same hard- ware, stream data to a topside cloud-based digital twin using a digital twin protocol like MQTT.”

OneSubsea, an SLB joint venture, is pushing ahead with subsea electri? cation, a move that has the potential to increase the amount and quality of data returned topside. The company has been awarded the FEED of a 12-well, all-electric subsea production system with an IoT for the subsea trees at Equi- nor’s Fram Sør ? eld, offshore Norway. As part of the agree- ment, future engineering, procurement and construction will be directly awarded to SLB OneSubsea conditional on a ? nal investment decision. The IoT includes three key digitalization efforts: intelligent sensors and actuators on the equipment (rather than spring-operated on/off systems), connectivity through a secure digital platform and the ability to turn data into decisions via analytics and diagnostics. “With all these pieces now in place, we have enabled intel- ligent asset lifecycle performance management for our sub- changing conditions to enhance safety and ef? ciency and re- sea production systems, including for the trees,” says John duce the need for travel and physical interventions.
