... Abstract Yggdrasil is the largest ongoing project development on the Norwegian Continental Shelf. It includes three production platforms, nine subsea manifolds, and 38 subsea trees. This paper highlights three innovative approaches implemented in the project: the use of optimized subsea...

... Abstract This paper examines the techno-economic feasibility of using a hybrid renewable floating hinged raft—combining wave energy, solar energy, and battery storage—to provide local, uninterrupted power to a brownfield development of four all-electric subsea trees located in the North Sea...

... subsea electric actuator technology enables a sustainable energy transition combining the ability to move high forces while being cost effective. For CO 2 storage, it enables an all-electric subsea tree, comparable in price to a traditional hydraulic tree, but without demanding expensive umbilicals...

... of Shetland, BP North Sea discovered they had a problem with subsea tree mounted pressure and temperature sensors that whilst dual redundant, still completely failed over time. The measurements are required by the local regulatory body to comply with monitoring of asset integrity and as such once failed...

... pumps driven by variable-speed motors for accurate positioning. This paper presents the results of the development of an electro-mechanical actuator with hydrostatic drive to operate gate valves of subsea trees and manifolds. The main achievements, demonstrated by simulation and testing using a 2...
