Kvaerner to install Husky’s West White Rose CGS

Canada’s Husky Energy has awarded engineering and construction services company Kvaerner a contract to tow and install the concrete gravity structure (CGS) for the West White Rose Project offshore Canada.

Husky said that the West White Rose CGS installation is scheduled for the second quarter of 2021.

The Canadian company is the operator of the White Rose oilfield offshore Newfoundland and Labrador. The West White Rose Project is being developed utilizing a fixed drilling platform consisting of a concrete gravity structure supporting integrated topsides.

Under the new contract with Husky, Kvaerner will perform engineering, analysis, planning, and execution of marine operations related to tow and installation of the CGS. At its final location offshore on the Grand Banks, Kvaerner will be responsible for installing the concrete gravity structure on the seabed.

Jan Arve Haugan, Kvaerner’s president and CEO, said: “Kvaerner was one of the main contractors for delivery of the floating production and offloading storage vessel SeaRose FPSO to Husky’s White Rose field. We are very proud that Husky has again selected Kvaerner for a key project.”

To remind, Husky awarded a contract for the construction of the CGS to a general partnership between SNC-Lavalin, Dragados Canada, and Pennecon in August.

As part of this general partnership, SNC-Lavalin and Dragados Canada each hold 40% of the shares, while local company Pennecon Ltd is a 20% partner.

The CGS will have an overall height of 145m, a base diameter of 122m and will require 76,000 m3 of concrete in its construction which will take place in a purpose built dry dock from 2017 to 2021.

The project development was approved by the company back in May and decided to use a fixed wellhead platform tied back to the SeaRose FPSO. First oil is expected in 2022 and the project is anticipated to achieve a gross peak production rate of approximately 75,000 barrels perday in 2025, as development wells are drilled and brought online.

The engineering work for the topsides of the White Rose wellhead platform was awarded in June to Wood Group.
