Petrojarl Knarr selected vessel for the Rosebank field


We are happy to confirm that Altera Infrastructure has signed a bareboat charter contract with Equinor for the redeployment of the Petrojarl Knarr FPSO to the Rosebank field, west of Shetland.

The Petrojarl Knarr FPSO is a vessel perfectly suited for redeployment in harsh waters. It is a relatively new and modern asset, and it was constructed to allow for electrification which would reduce operational CO2 emissions as well as additional features such as vapor recovery system and closed flare on the FPSO. The vessel has available space allocated for electrical equipment in both its mooring turret and on deck.

Chris Brett, President Altera Infrastructure Production; “We thank Equinor for putting their confidence in Altera and look forward to demonstrating our deep competence in harsh environment FPSOs and the latest emission reduction solutions available. Altera has an unrivaled track record in the operation of harsh environment FPSOs and we look forward to continuing our long presence in the West of Shetlands area through this premier development for the Rosebank Partners and to getting started on the project execution phase together with our key partners in Aker Solutions and Drydocks World Dubai.”

The vessel is planned to undergo life extension work as well as modifications to enhance energy efficiency for electrification, located at Drydocks World in Dubai. Petrojarl Knarr was built by Samsung Heavy Industries in South Korea and delivered in 2014. It has been operating on the Knarr field since 2015 until May 2022. Rosebank project development plans are pending final investment decision and regulatory approvals.

“Altera’s vision is to lead the industry to a sustainable future – and this will be an important partnership with Equinor on what is to be the most sophisticated redeployment for our industry. By working together, we believe we can make a meaningful impact on the future of the industry and deliver a good solution for the next decades on the Rosebank field”

About the field
Rosebank is an oil and gas field in the UK located about 130 kilometers off the coast of the Shetland Islands in the UK, which has an estimated 300 million bbl of potentially recoverable reserves. Equinor acquired operatorship of Rosebank in 2019 and has since been working to optimize and mature a development solution for the field, originally discovered in 2004, together with partners Suncor and Ithaca Energy.
