The Arctic is the frontier area to securing energy supplies for the future. Finding oil and gas in the Arctic and subarctic regions is in itself challenging. Extracting the hydrocarbons in a safe and economical way, is considered possibly even more challenging due to extreme low temperatures, ice conditions, remoteness and a sensitive natural environment. The paper is based on ongoing development of a subsea separation and storage system for application in deepwater arctic. The paper describes solutions on how deepwater subsea separation of hydrocarbons and storage of oil can be achieved in hostile environments enabling close to continuous production also when surface production facilities has to abandon location. Overall arctic field development suggestions are presented based on the solutions.
