摘要: Methods and systems for accurately measuring monitoring accumulated volume of hydraulic fluid in a blowout preventer (BOP) system, specifically function interest, are disclosed. One method includes initializing state machine algorithm, the algorithm responsive to BOP interest being activated; an initial flow rate baseline pressure create impedance variable use algorithm; aggregate system over time; applying negate flows not related interest; determine when has been completed total fluid.
