Intro
The Gina Krog FSO (“Randgrid”) is a floating storage and offloading vessel assigned to the Gina Krog field in the central North Sea. It serves primarily as an oil storage and offloading unit; it worked alongside the Gina Krog platform until oil export ceased via pipeline in 2024 and the FSO was removed following pipeline installation to Sleipner A.
Field
The Gina Krog field on the Utsira High in the central North Sea produces both oil and gas from Middle Jurassic sandstone of the Hugin Formation at depths of 3,300–3,900-m. Discovered in 1978 and produced from 2017, it is developed around a fixed platform; gas is exported via pipeline to Sleipner and oil previously offloaded via the FSO before pipeline infrastructure was installed.
Facilities
The Gina Krog FSO acted as a stationary storage and offloading vessel for crude from the Gina Krog platform. Oil produced on the fixed platform was routed to the FSO for intermediate storage; from there, shuttle tankers carried it to market. Gas was processed at the platform or routed via pipeline infrastructure to the Sleipner A facility and onward via the Gassled system. The FSO’s systems included storage tanks sized for field output and mooring arrangements suited to North Sea conditions. After oil pipeline commissioning in 2024, the vessel was demobilised from the field.
