It also is being made ready for electrification at Drydocks World in Dubai. The vessel is undergoing life-extension work, field-specific modifications, and enhanced energy efficiency. The vessel has space for electrical equipment in its mooring turret and deck. It had been operating for Shell in the Knarr field in the northern part of the North Sea from 2015 until May 2022.Īccording to Altera, the FPSO is a relatively new and modern asset, and it was constructed to allow for electrification, which would reduce operational CO 2 emissions, and additional features such as a vapor recovery system and a closed flare on the FPSO. Petrojarl Knarr FPSO was built by Samsung Heavy Industries in South Korea and delivered in 2014. The vessel will be deployed on the Rosebank field on a 9-year firm contract, with options for up to 25 years. Offshore services provider Altera Infrastructure was awarded by Equinor a bareboat charter and an operations and maintenance contract related to the Petrojarl Knarr FPSO. With electrification, the Rosebank lifetime upstream carbon dioxide (CO 2) intensity is estimated to decrease from 12 kg to about 3 kg CO 2/BOE, according to Equinor. Reuters reported that Equinor said the earliest the field would be electrified is 2030. The company acknowledges that “while there is a continued, though over time reducing the need for oil and gas, the remaining demand for oil and gas must be met with the lowest emissions possible.”Ĭompared to other oil fields, Rosebank will be optimized to reduce carbon emissions from its production through FPSO electrification. The field, said Equinor, is being developed in compliance with the North Sea Transition Deal, an agreement between the UK government and the offshore industry. Gas will be exported via a new gas export pipeline to the existing West of Shetland Pipeline Systems. New flowlines will connect the wells to the Petrojarl Knarr FPSO for hydrocarbon processing. Phase 2 will involve drilling up to three production and two water-injection wells. At its peak, the field is expected to produce 70,000 BOE/D after startup in 2026 or 2027 using the Petrojarl Knarr floating production, storage, and offloading (FPSO) vessel.Īccording to the environment statement filed with the UK government, Phase 1 comprises drilling four production and three water-injection wells, subject to learnings from initial wells. The field’s total recoverable resources of about 300 million bbl will be developed in two phases, with Phase 1 targeting an estimated 245 million bbl. Rosebank provides an opportunity to develop a field within the UK Continental Shelf, which will bring significant benefits to Scotland and the wider UK,” said Geir Tungesvik, executive vice president of projects, drilling, and procurement at Equinor. “Developing the Rosebank field will allow us to grow our position as a broad energy partner to the UK while optimizing our oil and gas portfolio and increasing energy supply in Europe. The UK government and the North Sea Transition Authority gave permission to the Norwegian energy provider and the UK-headquartered Ithaca-which hold 80% and 20% stakes in the field, respectively-to begin developing the large untapped oil field located 130 km northwest of the Shetland Islands. Equinor and Ithaca Energy are moving forward with their $3.8-billion offshore Rosebank field development project after reaching a final investment decision and securing government approvals.
