Project Profile
Location: Block F/2 , Dutch North Sea, Nederland
Reserves: 34 million barrels of oil, as well as 40bcf of associated gas
Water Depth: 1,340 and 1,478m
Area: 4.5km²
Start-up Year: 2000
Hanze was Veba Oil\'s (now Petro-Canada) first operatorship and the largest field to be developed in the Dutch North Sea. The development is based on a steel-gravity based production and storage platform. It is connected by a 1.5km long pipeline, running to a tanker-mooring and offloading facility for oil export. This facility will be the first single-point mooring system in the Dutch sector of the North Sea. Associated gas will be used to fuel the platform and excess gas will be transported to Den Helder, via pipelines. Hanze lies in block F/2 in the Dutch sector of the North Sea, about 200km northwest of Den Helder. The field has reserves exceeding 34 million barrels of oil, as well as 40bcf of associated gas. The field covers 4.5km² at a depth interval between 1,340 and 1,478m below sea level. The field was developed using nine wells under a four-well contract, plus two optional wells. Drilling is being carried out by the Jack-up Ensco 100, following the rig\'s conversion back to a drilling mode in December 2000.
DEVELOPMENT
The field was developed by a production platform on a steel gravity base. Veba placed the US$150 million turnkey contract with Hyundai Heavy Industries. The company, in turn, subcontracted Doris Engineering to draw up detailed designs regarding many aspects of the project. The gravity base structure (GBS) comprises a 14m high steel tank with skirts underneath and a framed tubular structure above. It was designed with a semi-fixing function, so as to allow it to move to other oil fields at the end of the Hanze production life.
