Gjøa is a large development project in the North Sea. The production at the field began in 2010 via a semi-submersible platform located off the Norwegian coast. The floating production facility is owned and operated by ENGIE E&P.
Oil and gas platforms typically use gas turbines to generate the electric power needed for their operations. Gas turbines consume large volumes of gas that could otherwise be sold and produce large quantities of CO2 (carbon dioxide) emissions. They have significant and costly space and weight requirements and require regular maintenance.
ENGIE E&P has therefore decided to prioritize the use of emission-free hydropower from the Norwegian grid to power offshore production facilities. It is a smart way of reducing the cost and the environmental footprint of its operations.
At the time of this project, the powering of a floating platform with electricity from the onshore grid had never been attempted as there was not yet any AC cable sufficiently robust to withstand the mechanical stress of floating applications.
ENGIE E&P turned to us for an innovative power cable system solution for Gjøa, based on prior successful partnership projects within power-fromshore solutions in the North Sea.
