Abstract: A turbomachine has a casing where liquid may accumulate; at least one liquid level detector is located inside the casing for automatically detecting liquid accumulated inside the casing during operation of the turbomachine; the liquid level detector may be arranged for detecting one or two or three or four liquid levels inside the casing; the liquid level detector is typically connected to an electronic unit at least for automatically signaling the liquid level. The electronic unit controls at least one valve for automatically discharging the accumulated liquid from the casing; in this way, the status of the turbomachine is not only monitored but also managed.

Abstract: The present invention concerns a motor-compressor unit, particularly a subsea motor-compressor unit comprising, housed in a single casing, a compressor and a motor, further comprising, inside said casing, a washing apparatus connectable to an external source of a washing agent for selectively washing specific target areas of said motor-compressor unit.

Abstract: A method for drain liquid collection and evacuation in a subsea compression system using a compressor, wherein an external drainage tank is arranged in direct flow communication with the compressor sump via a sump evacuation valve, the tank is set under compressor discharge pressure via a tank pressurizing line arranged to connect the tank to a compressor discharge flow upstream of a throttle valve, a tank evacuation line is arranged to connect the tank to the compressor discharge downstream of the throttle valve, drain liquid evacuation is accomplished through generation, by adjusting the throttle valve, of a flow restriction in the compressor discharge. The tank is set under compressor discharge pressure by opening of the pressure valve and the drain liquid flow is permitted into a reduced compressor discharge pressure downstream the throttle valve by opening an evacuation valve in the evacuation line.
