Dutch contractor Heerema Fabrication Group has been awarded a procurement and construction contract for the Peregrino II jacket by South Atlantic Holding B.V. on behalf of the Statoil Peregrino II project off Brazil.
The Peregrino field – discovered in 1994 – is a heavy oil field, situated in the South and South West section of the Campos Basin, approximately 85 kilometers of the coast of Rio de Janeiro, Brazil.
Statoil is the operator of the Peregrino field, which is presently developed with two wellhead platforms and a floating production, storage and offloading unit (FPSO). A system of pipelines, risers and cables connects this FPSO and the two wellhead platforms.
The Peregrino Phase II Field Development will add a third wellhead platform, as this area is not accessible by the existing two platforms. It contains an 8-legged jacket and a wellhead platform with a drilling unit (WHP-C) tied-back to the existing FPSO.
Koos-Jan van Brouwershaven, CEO of Heerema Fabrication Group, stated: “With the Valemon jacket, the Gina Krog jacket and the Oseberg Vestflanken 2 Unmanned Wellhead Platform – which we will deliver next month – we have a good track record with Statoil. We are pleased that Statoil still has confidence in the expertise and skills of our company despite the announced reorganization.”
According to Heerema, the Peregrino jacket will be approximately 135 meters tall, have a footprint of 66 x 53 meters and will weigh 9,300 tonnes (excluding the 12 piles). Construction is due to start in November 2017 at the Heerema yard in Vlissingen, the Netherlands, in order to be ready for sail away in October 2019.
Primary function of the jacket is the foundation for the topside including the drilling and process facilities, utilities, power generation, living quarters and a helideck with a design operational weight of 25,000 tonnes. The jacket is also designed for storage of fresh drill water with caissons for submerged pumps connected to such storage tanks.
Phase II will enhance production from the Peregrino field by increasing the number of production wells with a total of 21 – 15 oil producers and 6 water injectors – to be drilled from WHP-C. The water depth is approximately 120 meters. The start of the production of Phase II is expected by the end of 2020 and the estimated recoverable resources from this development until the end of 2040, when the concession period will end, are 250 million barrels.
