    Abstract: A method for thermal conditioning of a wind turbine nacelle is disclosed. The method comprises the steps of: Obtaining historical, statistical and/or forecast data relating to ambient conditions of the wind turbine, e.g. in the form of wind data, weather forecasts and/or thermal data of the wind turbine. Calculating a setting for at least one conditioning unit, e.g. a cooling unit or a heating unit, arranged in an interior part of the nacelle, based on the obtained historical, statistical and/or forecast data, and operating the conditioning unit(s) in accordance with the calculated setting. Measuring at least one parameter reflecting a temperature in the interior part of the nacelle. Adjusting the setting(s) for the conditioning unit(s) based on the measured parameter(s), and operating the conditioning unit(s) in accordance with the adjusted setting(s). The setting(s) is/are initially calculated based on the historical, statistical and/or forecast data, thereby providing a qualified starting point. The setting(s) is/are then adjusted or fine tuned on the basis of actual temperatures of the nacelle, thereby taking these into account and reaching optimal setting(s) quickly. An artificial intelligence (AI) system may be used. The method may include control of temperature and/or humidity inside the nacelle and/or temperature of components arranged in the nacelle.

    Abstract: A fluid tank (12) for a wind turbine (2), the tank (12) comprising: a housing (14) enclosing 5 an interior volume (16) for holding liquid, the housing (14) comprising a vent (36) positioned above a maximum liquid surface level in the interior volume (16), to permit air flow between the interior volume (16) and the surrounding environment, in use; a barrier (38, 138, 238) extending across the interior volume (16) to divide the interior volume (16) into an upper volume (40) and a lower volume (42), wherein the barrier (38, 138, 238) is disposed 10 beneath a minimum liquid surface level in the interior volume (16). At least one passage (62, 68) is provided in the barrier (38, 138, 238) to allow fluids to flow between the upper and lower volumes (40, 42); and at least one opening (28, 32) through which liquid can be communicated into or out of the lower volume.

    Abstract: A pipe coupling comprising a pipe branch (2), a hose (3), and a retainer (4). The pipe branch forms a proximal branch section (5) terminating the pipe branch, a distal branch section (6) in extension to the proximal branch section, and an expanded section (7) with an increased diameter between the proximal branch section and the distal branch section. The hose terminating axially in an opening configured to receive the proximal branch section (5) in an axial direction and comprising a proximal fold (9), a distal fold (10), and an internal gasket (11) between the proximal fold and the distal fold, the gasket being arranged to seal between an inner surface of the hose and an outer surface of the proximal branch section. The retainer being configured to enclose the pipe branch and the hose and forming a proximal flange (12) and a distal flange (13), the proximal flange and the distal flange both extending inwardly and defining a passage for the pipe branch (2), the passage having an internal diameter which is smaller than the increased diameter, the proximal flange being configured for engaging the proximal fold and the distal flange being configured for engaging the distal branch section. The pipe coupling provides an easy and reliable connection e.g. between vibrating machine components or components which move relative to each other.
