Abstract
The present invention relates to a subsea hydraulic control device () for hydraulically controlling a subsea module (). The control device () comprises a hydraulic distribution unit () with a valve unit () and a manifold unit (), where hydraulic fluid lines are provided in the valve unit () and in the manifold unit (). The hydraulic distribution unit () comprises a low pressure hydraulic input port () connectable to a low pressure fluid source (LP) and connected to a low pressure fluid line () within the hydraulic distribution unit (), a high pressure hydraulic input port () connectable to a high pressure fluid source (HP) and connected to a high pressure fluid line () within the hydraulic distribution unit (), a return port () connectable to a return fluid reservoir (R) and connected to a return fluid line () within the hydraulic distribution unit () and a number of hydraulic output ports () connectable to subsea actuators (A) of the subsea module (). A section of the low pressure fluid line () is provided as a first fluid bore (B) in the manifold unit () and a section of the high pressure fluid line () is provided as a second fluid bore (B) in the manifold unit (). The configuration of the respective bores (B, B) in the manifold unit () is determining which of the output ports () being a low pressure output port () connected to the low pressure fluid line () and which of the output ports () being a high pressure output port () connected to the high pressure fluid line ().
