(With videos) Heerema Fabrication Group (HFG) has completed the project for the Culzean wellhead jacket and access deck for client Maersk Oil.

The wellhead jacket and the wellhead access deck have set out from Heerema Vlissingen (the Netherlands) and Heerema Hartlepool (the United Kingdom) respectively. Once they reach their final destination, the Ultra High Pressure High Temperature Culzean development field in the UK sector of the North Sea, Heerema Marine Contractors will perform the installation.

On 21 October 2014, Maersk Oil awarded HFG the Procurement & Construction contract. The jacket has a height of 114 metres, a footprint of 31 x 31 metres and a top of 22 x 22 metres. The wellhead jacket, the wellhead access deck and the access ways together weigh 7100 tons.

Culzean Field

The Culzean field – discovered in 2008 – is situated in the UK sector of the Central North Sea approximately 250 kilometres east of Aberdeen in license block 22/25a. The water depth is approximately 88 metres and the reservoir is located around 4300 metres below sea level.

The overall Culzean development concept consists of a wellhead platform, a central processing facility platform and a separate utilities and living quarter platform with capacity for over 100 people. The platforms will be linked via two bridges approximately 100 metres in length.

First gas is currently expected in 2019. The Culzean project has the potential to meet around five per cent of the UK gas consumption in 2020/21.
