On 11 May 2019 hydrocarbons were introduced into the Aoka Mizu FPSO’s process system. Introduction of hydrocarbons is the final stage of the FPSO’s commissioning and marks the commencement of the Lancaster EPS start-up phase. During this phase,each of the two production wells will be individually tested and shut-in for data gathering purposes. Cleaning and testing(pigging) of the flowlines for flow assurance purposes will also take place during these shut-ins.The start-up phase will conclude with simultaneous flow from both wells for 72 consecutive hours, after which a further announcement of ‘First Oil’ will be made.
