Heerema Fabrication Group has awarded a contract to DGI Doedijns to design and deliver the flooding system upend control system for the Peregrino II Jacket.
The flooding system upend control center consists of 56 actuated valves, a control centre, interconnecting hoses. DGI Doedijns provides also the yard installation of the equipment.
The Peregrino II Jacket will be about 135 meters tall, have a footprint of 66 x 53 meters, and will weigh 9,300 metric tons (excluding the 12 piles).
Jackets, like the Peregrino II are designed to float and the legs act as floating chambers. The upend control centre, a self-contained unit, supplies hydraulic power to operate a series of spring return actuated valves. These valves will control the flooding of the floating chambers of the jacket. By flooding the legs with water, the jacket will upend and can be installed safely.
The eight-legged jacket is part of a wellhead platform with a drilling unit (WHP-C) tied-back to the existing floating production storage and offloading (FPSO) and will be operating in the Peregrino Phase II field development. The construction of the Peregrino II Jacket will be at the Heerema yard in Vlissingen, the Netherlands, in order to be ready for sail away in October 2019.
