Abstract
A method and an apparatus (280) for determining an estimate of a position of a hydraulic subsea actuator (200), wherein the hydraulic subsea actuator (200) has a fluid port (220) fluidly connected to a fluid source (260). The apparatus (280) comprises a hydraulic cylinder (310) connected in series between the fluid source (260) and the fluid port (220) of the hydraulic subsea actuator, and a movable piston (320) arranged in the second hydraulic cylinder (310), a position determining device, arranged to determine a position of the movable piston (320), and a signal processing device (350), arranged to calculate the estimate of the position of the hydraulic subsea actuator based on the position of the movable piston.
