SANDNES, Norway – Aker Solutions has contracted GE for more than 130 subsea wellhead sensors to install in the Goliat field in the Norwegian Barents Sea. Operator Eni Norge awarded Aker the EPC contract for the subsea equipment last year.

GE’s Sensing division will deliver the PTX400 sensors over the next two years. Goliat is expected to produce first gas and condensate in 2013.

Aker’s contract includes subsea templates and manifolds, riser bases, subsea trees and control systems, and umbilicals and workover systems. The PTX400 sensors will be installed on the trees and manifolds in 1,800 m (5,905 ft) water depth, providing long-term measurement for flow assurance and integrity purposes.

GE says the PTX400 series meets increasingly strict requirements for subsea operation, and offers high reliability in depths to 4,500 m (14,764 ft). The sensors featuring the company’s (Druck) propriety piezo-resistive measuring technology, which it has developed over the past 40 years,

They are designed to measure pressure to an accuracy of better than 0.025% FS and temperature better than 0.2% FS. Digital characterization provides a high degree of accuracy, GE claims. The versions for Goliat also feature dual redundancy outputs.
