    摘要： A method of sharing load between a plurality of parallel fluid pumps in a subsea fluid pumping system (1) comprising a first fluid pumping unit (2a) comprising a first pump (3a) and a first motor (8a) which is drivingly connected to the first pump, which first pump comprises a suction conduit (4a) which is in fluid communication with a fluid inlet conduit (5), and a discharge conduit (6a) which is in fluid communication with a fluid outlet conduit (7); a second fluid pump unit (2b) comprising a second pump (3b) and a second motor (8b) which is drivingly connected to the second pump (3b), which second pump comprises a suction conduit (4b) which is in fluid communication with the fluid inlet conduit, and a discharge conduit (6b) which is in fluid communication with the fluid outlet conduit, thus rendering the second pumping unit parallel to the first pumping unit; a return conduit (9) providing a feed-back path for the fluid from the outlet conduit to the inlet conduit; and a control valve (10) controlling the flow of the fluid through the return conduit. The method comprises the steps of establishing pump limit characteristics diagrams (15a, 15b) for the first and second pumping units by mapping a minimal allowable torque of each pumping unit as a function of a differential pressure across the corresponding pump and identifying a permissible operating region (16a, 16b) of the pumping units defined by a set of minimum allowable torque values; monitoring the torque of the pumping units and the differential pressure across the pumps acquiring a monitored torque value and a monitored differential pressure value of the pumping units, and identifying the minimum allowable torque value of the pumping units corresponding to the monitored differential pressure value; and regulating the rotational speed of the pumps such that the relation between the monitored torque values is the same as the relation between the minimum allowable torque values of the pumping units.

    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： The invention relates to a tool and associated method for making closed operation in subsea wells possible, without the use of cable or coiled tubing up to the rig or ship. The object of this solution is to move such operations to lighter and more cost efficient vessels or ships which are not necessarily required to handle hydrocarbons up to the deck of the vessel. The basis of maintaining two independent well barrier envelopes is met even if the tool and the method for operation does not require cutting functions for isolating the well from the environment. The tool comprises a hoist arrangement, a seal element and connection points. The localization and arrangement of these are essential for the invention. The invention also adapts for use of traditional workover systems as alternative, independent operation, if the new technique should not complete the operation as planned.
