The JV will build a concrete gravity structure (CGS) for a fixed drilling platform. The CGS, with an overall height of 145m and base diameter of 122m, will require 76,000 cu m of concrete in its construction, which will take place in a purpose built dry dock from 2017 to 2021. Once completed and installed in the White Rose field, the CGS will support a topside module to enable drilling and oil extraction 350km away from the coast of Newfoundland in the Atlantic Ocean. 

The structure will be built in Argentia, an industrial area on the southwest coast of the island of Newfoundland, before being moved offshore. Work on the project is expected to begin shortly and construction is expected to finish in 2021. 

SNC-Lavalin and Dragados Canada each hold 40% of the shares in the partnership, while local company Pennecon is holds 20%.

The original White Rose field was developed using subsea technology, consisting of three drill centers tied back to a floating, production, storage and offloading (FPSO) vessel. Production is provided by subsea wells in the Southern and Central drill centers while surplus gas is re-injected into the Northern Drill Center for future extraction. The North Amethyst and South White Rose extensions all produce back to the SeaRose FPSO.  

The West White Rose Project will access further resources to the west of the field, using a fixed drilling rig tied back to the existing SeaRose FPSO. First oil is expected in 2022.
