GE scoops Goliat field contract

31 August 2010

Aker Solutions will install more than 130 GE Sensing wellhead sensors throughout the Goliat field, located within the Norwegian sector of the Barents Sea. Aker was awarded the engineering, procurement and construction (EPC) contract in 2009 by field licensee and operator, Eni Norge.

The sensors will be delivered over the next two years and production from the field is expected in 2013.

Fabian Dawson, global commercial manager, Upstream, at GE’s Sensing business, said he was excited to working with Aker Solutions.

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 1800 metres 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 4500m. 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%FS and temperature better than 0.2%FS. They feature digital characterisation for high accuracy and the versions to be supplied to the Goliat project will also feature dual redundancy outputs.
