A method of cleaning deposited solid material from a fouled portion of a gas compressor () whilst the gas compressor () is in situ in a natural gas processing system () is provided. The method comprises the steps of supplying a liquid cleaning agent to a gas inlet of the gas compressor (), the liquid cleaning agent being capable of removing the deposited solid material; passing the liquid cleaning agent through the gas compressor () to a gas outlet of the gas compressor (), wherein at least a portion of the cleaning agent remains in a liquid state as it passes through the fouled portion of the gas compressor (); and recovering a fluid containing removed material that is output from the gas compressor () so as to prevent the removed material reaching one or more gas processing stages of the gas processing system () downstream of the gas compressor ().

A method of identifying the phase composition and/or changes in the phase composition of a fluid flowing through a turbomachine includes monitoring changes in at least one electrical parameter associated with operation of the turbomachine, and employing a known correlation between phase composition and or phase composition changes, and changes in the electrical parameter(s) to associate the monitored changes with changes in the actual phase composition of the fluid.

Determining the phase composition of a fluid flow

A method of dynamically controlling a wind turbine having a rotor supporting a plurality of blades and a main bearing supporting the rotor, the method comprising detecting a load profile around the circumference of the main bearing, generating a control signal based on the detected load profile and dynamically adjusting the load profile of the main bearing using the control signal.

Wind turbine control

A method of operating and cleaning a compressor comprising the following steps: passing a first fluid through the compressor, the first fluid comprising gas from a separator wherein the compressor is operating to compress the first fluid passed therethrough, mixing well fluid bypassed from upstream of the separator with the gas from the separator to produce a second fluid comprising gas and liquid wherein the gas and liquid are from at least one well; and passing the second fluid through the compressor, wherein the second fluid is passed through the compressor for a limited time period to clean a surface inside the compressor, the compressor operating to compress the second fluid passed therethrough.

Subsea compressor cleaning method wherein the cleaning liquid is retrieved from the multiphase process fluid

There are described methods and apparatus for operating and/or cleaning a compressor. In an embodiment, a first fluid comprising gas may be passed through the compressor, while the compressor operates to compress the first fluid. A second fluid may be passed through the compressor, the second fluid comprising gas and liquid from at least one well. The second fluid may be passed through the compressor for a limited time period to clean a surface inside the compressor, while the compressor operates to compress the second fluid.
