HVDC module for Johan Sverdrup Phase two
As part of the major offshore oil field development on the Norwegian Shelf, Johan Sverdrup Phase 2, BigLift was awarded the transport of a 4,200 mt High Voltage Direct Current module (HVDC) from Cadiz, Spain to Haugesund, Norway. The module measures 44*62*40 m (lbw) and was loaded over portside using SPMTs.
Due to the quay layout, the module had to be loaded over BigLift Barentsz’ portside far aft side of the deck. Once on board, the module was shifted forward to its final stowage position. With the extensive ballast and structural capacity of BigLift Barentsz, this was no problem at all for the vessel. Even if the project was scheduled to take place in the Biscay Autumn, meticulous voyage planning and good coordination between clients, the vessel and the BigLift office support team made sure the voyage was completed safely and on schedule. In the preparation stage, BigLift supported the clients’ engineering team by performing detailed motion studies, structural verifications and ballast plans. For BigLift, this shipment is the second of three in the Johan Sverdrup Phase 2 development, awarded by our client Aibel AS. Earlier this year mv Poolgracht transported steel UPM sections from Laem Chabang, TH, to Haugesund, NO, and during the first half of 2021 BigLift will be moving a 100 m flare tower between the same countries on another BigLift heavy-lift vessel.
Johan Sverdrup field
The Johan Sverdrup field lies approximately 150 km west of Stavanger, Norway, in the Norwegian North Sea. It is one of the biggest oil fields in the Norwegian continental shelf. The field is jointly owned by Equinor (42.6%, operator), Lundin Norway (20%), Petoro (17.36%), Aker BP (11.57%) and Total (8.44%). The field is being developed in two phases. Construction on the second phase began in May 2019 and commissioning is expected in the fourth quarter of 2022. Johan Sverdrup is expected to contribute to more than half of Norway’s oil production by 2040. The production life of the project is estimated to be 50 years.
