Statoil, the operator for Heidrun, is in the process of developing a new solution for oil exports from the Heidrun field. The Heidrun Oil Export Solution (HOES) includes a new loading buoy and risers at one of the existing buoy locations and a new permanently anchored floating storage unit (FSU) tied into the new system. This vessel will act as a combined storage vessel and unit for offloading stabilised crude oil to shuttle tankers.
Pursuant to the Regulations relating to management and the duty to provide information in the petroleum activities and at certain onshore facilities (the management regulations) Section 25 third para item a, the PSA has granted Statoil consent to use a loading buoy for Heidrun oil export on the Heidrun field.
The Heidrun field is at Haltenbanken in the Norwegian Sea in blocks 6507/7 and 6507/8. The field has been developed using a concrete floating tension leg platform over a subsea template with 56 well slots. The northern part of the field is produced using subsea facilities.
Water depth in the area is around 350 metres.
Production on the field began in 1995. The gas from Heidrun transits a dedicated pipeline to Tjeldbergodden and then Åsgard Transport to the gas-processing facility at Kårstø. Export of stabilised crude currently takes place through two loading buoys to shuttle tankers.
