Argentia Wellhead Platform for White Rose Extension

Proponent: Husky Energy

Summary of Environmental Assessment Process

Project Description:

The proponent proposes to construct a wellhead platform (WHP) that will consist of a concrete gravity structure (CGS) to be built at Argentia, on the former US Navy Base site. The CGS will be constructed in a purpose-built graving dock. The proposed graving dock will be excavated behind the natural coastal shoreline to a depth of approximately 20 metres below sea level. The graving dock will be a less than 5 hectares flooded area when the bund/retaining wall is removed. Upon completion, the CGS will be floated to one of two deep-water sites in Placentia Bay, where it will be mated with the topsides structure. The WHP will then be towed to the White Rose oil field and tied back to the SeaRose FPSO. The overall construction site area will be approximately 15 hectares. Support facilities will include a concrete batching plant, offices, a mess hall, a medical clinic, temporary sheds, lay down areas and storage areas. Site work for construction of the graving dock is scheduled to begin in April 2013 to achieve first oil by fourth quarter of 2016.
