OSLO, Norway – Aker Solutions has contracted GE’s Sensing business for over 130 PTX400 subsea wellhead sensors for installation in the Goliat field in the Norwegian Barents Sea. The sensors will be delivered over the next two years.
The equipment will be installed on subsea trees and manifolds that Aker is supplying to operator Eni Norge, for use in water depths of up to 1,800 m (5,905 ft). The sensors will provide long-term measurement for flow assurance and integrity purposes.
GE says the PTX400 series is designed to meet stricter requirements for subsea operation and to provide high reliability in water depths of up to 4,500 m (14,764 ft). The sensors, which feature the company’s Druck proprietary piezo-resistive technology, are claimed to measure pressure to an accuracy of better than 0.025%FS and temperature better than 0.2%FS.
Digital characterization is another feature, and the versions to be supplied to Goliat project will also incorporate dual-redundancy outputs for enhanced reliability.
