摘要： The present invention relates to a subsea control valve (10) for controlling the supply of hydraulic fluid to a subsea fluid-actuated device (4). The valve comprises a housing (11) with an input fluid line bore (16) connectable to a input fluid system (2), a return fluid line bore (17) connectable to a return fluid system (3) and an actuator fluid line bore (18) connectable to the fluid-actuated device (4). A ball valve member (20) with a through bore (21) is pivotably connected within the housing (11) between the input fluid line bore (16), the return fluid line bore (17) and the actuator fluid line bore (18), the ball valve member (20) having a first and a second position. The actuator fluid line bore (18) and the return fluid line bore (17) are connected to each other via the through bore (21) when the ball valve member (20) is in its first position, thereby allowing fluid to be returned from the fluid-actuated device (4) to the return fluid system (3). The input fluid line bore (16) and the actuator fluid line bore (18) are connected to each other via the through bore (21) when the ball valve member (20) is in its second position, thereby allowing fluid to flow from the input fluid system (2) to the fluid-actuated device (4).

摘要： A method of protecting a hydrocarbon pump (6) from excessive flow rates in a system for pumping a hydrocarbon fluid, which system comprises said pump and an electrical motor (10) for driving the pump. The method comprises the steps of: for each of a plurality of gas volume fraction values of the hydrocarbon fluid, establishing a maximum torque limit for the pump by mapping the maximum allowable torque of the pump as a function of the differential pressure across the pump, thereby creating a plurality of maximum torque curves (4), each representing the maximum torque limit for a unique gas volume fraction value; from the plurality of maximum torque curves (4), establishing a master maximum torque curve (5) which represents the maximum torque limit for all gas volume fraction values; monitoring the torque of the pump and the differential pressure across the pump; based on the monitored differential pressure (DP′) and using the master maximum torque curve, establishing a maximum allowable torque (T′) for the pump; and taking a predetermined action if the monitored torque exceeds the established maximum allowable torque (T′), e.g. raising an alarm and/or shutting down the system.

摘要： A subsea AC power supply device comprises a subsea transformer, having a primary winding arranged to be connected to a topside AC power supply via a subsea power supply cable, and a subsea shunt reactor, connected in parallel with the primary winding of the subsea transformer. The subsea transformer and the subsea shunt reactor are arranged within a common subsea watertight housing. A subsea AC power supply system comprises a topside AC power supply, a subsea power supply cable connected to the topside AC power supply, and a subsea AC power supply device connected to the subsea power supply cable.
