摘要： The invention relates to a subsea deployable installation and workover control system (IWOCS) skid (1) for connection to a subsea component (2), the skid (1) comprising: a wireless communication unit (3) for communication with a wireless communication unit (4) at a topside installation (10); a control system (69) for data storage and/or data filtering and transferring the filtered data to the wireless communication unit (3) and receiving data from the wireless communication unit (3); a self-contained fluid system comprising a fluid supply tank (5, 8), the fluid system being configured to be connected to a fluid connection on the subsea component such as to provide fluid to the subsea component (2); an electric power source (7) for supplying electric power to the communication unit (3) and the control system (69). It is further described a method of performing installation or workover operation(s) on a subsea component using an installation workover control system (IWOCS) skid.

摘要： 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.
