GE to supply wellhead sensors for Goliat project


GEs Sensing Business was awarded a contract to supply around 130 subsea wellhead sensors for installation in the Goliat field, which is located within the Norwegian sector of the Barents Sea.

Aker Solutions placed the order for the sensors which will be delivered over the next two years and production from the field is set to start in 2013. Aker won the contract for the Engineering, Procurement and Construction (EPC) in 2009 by the field operator Eni Norge.

The scope of the Aker contract includes subsea templates and manifolds, riser bases, subsea trees and control systems as well as umbilicals and workover systems. The PTX400 sensors will be installed on the trees and manifolds at depths of up to 1,800m and will provide long-term precise measurement for flow assurance and integrity purposes.

The PTX400 series has been designed to meet the increasingly stringent requirements for subsea operation and offer extremely high reliability at seawater depths of up to 4,500m.

"Featuring GE's (Druck) propriety piezo-resistive measuring technology continuously developed over the last 40 years, the PTX400 series can measure pressure to an accuracy of better than 0.025 per cent FS and temperature better than 0.2 per cent FS. They feature digital characterisation for high accuracy and the versions to be supplied to the Goliat project will also feature dual redundancy outputs for greater reliability," Fabian Dawson, Global Commercial Manager, Upstream, at GE's Sensing Business, said.
