Start-up Year: 2001
Elgin-Franklin is the world\'s largest High-Pressure / High-Temperature (HP / HT) development. In 1995, project partners decided to jointly develop the fields as a hub, due to their close proximity and shared HP/HT status. Approved by the UK authorities in 1997, field development includes an unmanned wellhead platform on both Elgin and Franklin tied-back to a shared processing and export platform. Estimated costs for the project reached US$2.86 billion. Comprised of a steel jacket and four legs, the Franklin wellhead platform accommodates nine platform slots. Also consisting of a steel jacket and four legs, the Elgin wellhead platform can accommodate 12 platform slots. linked to the Elgin platform via a bridge, the Processing, Utilities and Quarters (PUQ) platform separates recovered condensates from natural gas, processing the former into commercial quality. The PUW platform is located on the Elgin field and is linked to Franklin by an interfield pipeline bundle.
Built by a consortium of Technip, McDermott and Barmac, the platform is based on the TPG 500 jackup concept of a self-elevating and self-piling jackup facility with a triangular hull atop the pilings. With a 70-person operational crew, the Elgin PUQ can accommodate up to 97 personnel. Production started from Elgin in March 2001, and Franklin began producing in August 2001. Peak production for hub facility is 280,000 boepd, or 175,000 bpd of condensate and 547.4 MMcf/d (15.5 MMcm/d) of gas.
