Kiewit-Kvaerner JV Work on Exxon’s Hebron GBS in Canada

Kiewit-Kvaerner Contractors joint venture, has been authorised by ExxonMobil Canada Properties (EMCP) to proceed with work on the Hebron Project gravity based structure (GBS) project offshore Newfoundland and Labrador, Canada.

The authorisation comes after the substantial completion of front end engineering and design services and awards the next phase, which includes detailed engineering, procurement and construction (EPC) related services. Kvaerner estimates its share of this work to be approximately USD 125-150 million.

Hebron is a heavy oil field estimated to have 400 – 700 million barrels of recoverable resources. The field was first discovered in 1981, and is located offshore Newfoundland and Labrador in the Jeanne d’Arc Basin 350 kilometres southeast of St. John’s, the capital of Newfoundland and Labrador. It is approximately 9 kilometres north of the Terra Nova project, 32 kilometres southeast of the Hibernia project, and 46 kilometres from the White Rose project. The water depth at Hebron is approximately 92 metres.

The Hebron field will be developed using a stand-alone concrete GBS. The GBS will consist of a reinforced concrete structure designed to withstand sea ice, icebergs, and meteorological and oceanographic conditions at the offshore Hebron Project Area. The preliminary GBS concept has a single main shaft supporting the topsides, encompassing all wells.

The Hebron co-venturers are: ExxonMobil Canada Properties (36%), Chevron Canada Resources (26.7%), Suncor Energy Inc. (22.7%), Statoil Canada (9.7%) and Nalcor Energy (4.9%).
