Heerema Fabrication Group has been awarded the Engineering, Procurement & Construction contract of the Culzean jackets for both the central processing facilities platform and the utility & living quarter platform. The client is Maersk Oil North Sea UK Limited, operator of the Culzean field in the North Sea.
This contract is the second HFG has won for the Culzean project. On 21 October 2014 the Procurement & Construction contract of the Culzean wellhead platform jacket, wellhead access deck and access ways was awarded. As part of the contract, six pile sleeve clusters will be fabricated at Heerema’s Hartlepool facility in the UK, in addition to the Wellhead Access Deck already underway at the yard.
Koos-Jan van Brouwershaven, Chief Executive Officer of HFG, states: “We are very pleased that we have been able to secure this second contract for the Culzean Field Development. It puts us in the position to continue to build on the strong and pleasant relationship with Maersk Oil North Sea UK. For the duration of the work on the jackets in the UK we expect to support 250 jobs for the local Hartlepool community including our Heerema Hartlepool yard.”
Culzean is an Ultra High Pressure High Temperature Development field. It is one of the largest gas discoveries of recent years in the UK sector of the North Sea. Both jackets will be approximately 115 metres tall and have a footprint of 38 x 38 metres. The jacket for the central processing facilities (CPF) has a top of 24 x 30 metres and a weight of almost 8,000 tonnes. The top of the utility & living quarter (ULQ) jacket will be 24 x 24 metres and this jacket will weigh 6,800 tonnes. Construction is due to start in January 2016 to be ready for sail away in June 2017.
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 4,300 metres below sea level. The overall Culzean development concept consists of a wellhead platform, a central processing facility platform and a separate utility & 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 5% of UK gas consumption 2020/21.
