System for control of a subsea located compressor fluidly connected to receive an inlet flow of gas through an inlet line, said flow may include liquid in an amount that may vary. The control system comprises a sensor means for measuring and determining the liquid droplet size distribution and liquid volume fraction, operatively arranged to the inlet line, and a control means operatively connected to the sensor means for operation of the control means based on input from the sensor means. Method for control of a subsea located compressor.

Control of subsea compressors

The invention relates to a monitoring system and method for accumulator banks including at least two pressure accumulators, the accumulator bank is coupled to a device and being adapted to provide a pressurized fluid into the device at pressure reductions in said device. The monitoring system comprises at least one sensor for detecting a chosen parameter in the accumulator bank at chosen intervals of time, and a recording unit for recording the sampled measured parameters, a storage device for storing predetermined characteristic information related to the pressure development in the accumulator bank during pressure reductions at the device and representing different numbers of active accumulators in the accumulator bank, and calculation means for comparing the recorded measured parameters with the stored characteristic information, and determining from this comparison the number of active accumulators in the accumulator bank.

An actuator system including a shaft, elements arranged to power the shaft and at least one actuated member actuated by the elements arranged to power the shaft. The elements arranged to power the shaft include a plurality of transverse flux motors.

Actuator system

A device for electrical coupling between a first and a second pipe section mechanically coupled to each other and forming a pipe adapted for transportation of a fluid. The first pipe section includes a first electric winding and the second pipe section includes a second electric winding. The first and second windings are adapted for inductive coupling between the first and the second pipe section.

Device and a method for electrical coupling

Apparatus for use in monitoring particles in a fluid flow comprises: a duct () for receiving the fluid flow; light generating means () adjacent the duct for transmitting light into the fluid flow via a first at least partially light-transmissive part () of the duct; light-responsive detection means () adjacent a second at least partially light-transmissive part () of the duct for receiving light from the light generating means which has passed through the fluid flow; processing means () for location remotely from said duct; and means () for coupling the processing means with the detection means, the processing means being adapted for processing signals therefrom to provide data relating to particles in the fluid flow.
