The Peregrino Phase II field development will access new acreage out of reach of its current two wellhead platforms and floating production, storage, and offloading vessel. The contract was let in June 2016 (OGJ Online, June 28, 2016). According to Heerema Fabrication Group, the 8-legged jacket will include a wellhead platform with a drilling unit (WHP-C) tied back to the existing FPSO.
The 135-m tall Peregrino jacket will have a 66 x 53-m footprint, weighing 9,300 tonnes (excluding 12 piles). The company, which is constructing the jacket on behalf of South Atlantic Holding BV on behalf of Statoil ASA, will start construction in November at the Heerema yard in Vlissingen, the Netherlands. The installation is expected to sail away in October 2019.
The jacket will serve as a foundation for the topside, which will include the drilling and process facilities, utilities, power generation, living quarters, and a helideck with a design operational weight of 25,000 tonnes. The jacket also is designed for fresh water storage to assist drilling caissons for submerged pumps connected to the storage tanks.

The third wellhead platform will be installed in 120 m of water and is expected to start production by yearend 2020. Peregrino Phase II is estimated to add recoverable resources of 250 million bbl of oil by the end of 2040, when the concession period ends (OGJ Online, Feb. 27, 2015).
