Abstract: A method of operating a wind turbine, in particular plural wind turbines of a wind park, includes: receiving, by the wind turbine or a wind park controller, safety relevant information from an external source external to the wind turbine; activating, by the wind turbine or the wind park controller, a safe operation mode depending on the received information, wherein the external source is different from a wind park controller.

Abstract: The present disclosure provides a method for analyzing an input by a user received by a client on a server; the method comprising of; sending a content to be displayed by the client from the server to the client; receiving from the client, an input information by the user to the client during the content is displayed; analyzing the input information by the user received from the client; and changing the content to be displayed by the client based on the result of the analysis; and sending the changed content to the client.

Abstract: A method of handling a wind turbine is provided including a nacelle coupled via a yawing system to a tower for protection against high wind load, the method including: supplying a control signal to a yawing actuator of the yawing system, while the nacelle is in a first orientation; exerting, by the yawing actuator, a torque to the nacelle relative to the tower, thereby turning the nacelle to a second orientation being a downwind orientation.

Abstract: The present disclosure provides a method for sending at least one 3D object from a server to a client, the method including: extracting color information, alpha information and geometry information from the 3D object on the server; simplifying the geometry information; and encoding a stream including the color information, the alpha information and the simplified geometry information and sending the encoded stream from the server to the client.

Abstract: An oil well rotating cement head includes a swivel assembly and a plug launcher assembly. The swivel assembly includes a swivel shaft and a collar-shaped, outer swivel subassembly. The swivel shaft has an internal through bore and windows extending through the swivel shaft, and extends through the outer swivel subassembly. The swivel shaft and outer swivel subassembly enclose an inner annular gap in fluid communication with the windows of the swivel shaft. A material inlet formed in the outer swivel subassembly is in fluid communication with the inner annular gap. The plug launcher assembly is affixed to the swivel shaft and releasably holds one or more oil well cementing plugs. The plug launcher assembly provides fluid communication from the internal through bore of the swivel shaft to a bottom end of the plug launcher assembly.

Abstract: A system includes a load moving machine, including a frame and a movable assembly coupled to the frame. The movable assembly includes a lift portion, a rotational portion, a first translational portion, and a second translational portion.

Abstract: Load transport and retraining devices and methods for restraining industrial machines or heavy machinery, such as, turbines, to prevent displacement during adverse environmental conditions, such as, pitching and rolling seas, are provided. The devices include support structures adapted to support loads and having wheels positioned and adapted to engage rails. The wheels include a first set of wheels adapted to ride on top of the rails and a second set of wheels adapted to engage the sides of the rails and thereby retain the support structure to the rails. The devices may also include a third set of wheels adapted to also engage the sides of the rails. The devices may include brake and drive assemblies to facilitate handling. Aspects of the disclosure are uniquely adapted to turbines, but other aspects of the disclosure may restrain any industrial machine that may be exposed to adverse environmental conditions.
