摘要： Seismic soil probe (1) comprising a body for insertion into the soil, a seismic sensor (3) located at a first region of the body, and a seismic generator (2) located at a second region of the body for emitting seismic signals. The seismic generator (2) comprises a hammer (6), a biasing member (7) for biasing the hammer (6) into contact with a surface (21), and an actuator (5) operable to move the hammer (6) against the bias away from the surface (21) to a primed position and to release the hammer (6) from the primed position for impacting the surface (21) to generate a seismic wave signal.

摘要： Floating vertical wind profile sensor or LiDAR device (1) comprising a vertical wind profile sensor sensor (8) for sensing a vertical wind profile, a self-propulsion system (24) for propelling the device through a body of water, and a deployable special mark (10), actuatable to switch between a deployed state for identifying the device as a special marker buoy and an undeployed state for identifying the device as a vessel. A controller (22) is provided for switching the device (1) from a vessel mode to a buoy mode when the vessel is anchored. The controller (22) switches the special mark (10) to the deployed state when the device (1) is in the buoy mode. The method involves the floating LiDAR device (1) navigating to a target location and the buoy mode being activated while vertical wind profile data are collected.

摘要： Wind turbine lightning stroke diagnostic apparatus for a wind turbine having conductive blades. A lightning protection system input is provided for receiving measured current data associated with a current conducted by the lightning protection system following a lightning stroke. An air pressure sensor is mounted using a mount within an internal cavity of a conducive wind turbine blade assembly. A sensor monitor monitors the measured current data and the output of the air pressure sensor for identifying a bypass lightning stroke when a measured current increase coincides with the detection of a lightning generated shockwave within the internal cavity by the air pressure sensor.

摘要： A method for the use in offshore crew transfer when transferring a person between a crew transfer vessel and a structure or vice versa where a prediction system for predicting vessel bow motion in response to sea waves detected by said wave detection device is used. An indicator is adapted to indicate a prediction of vessel bow motion below a first bow motion threshold value within a first predetermined time period based on said prediction system. The transfer of the person only takes place when said vessel bow motion is indicated to be below the first vessel bow motion threshold value within the first predetermined time period.
