Abstract: An offshore wind turbine apparatus may include a platform and an equalizer with sealed internal volumes, a turbine mast connected to the platform, a turbine which is connected to the turbine mast, and turbine blades connected to the turbine. The apparatus may be rotatably mounted on a barge via a trunnion. The apparatus may rotate from a substantially horizontal position to a substantially upright position when sufficient ballast material is inserted into the equalizer. The equalizer may rest on a sea floor. The platform may provide a restorative buoyant force that tends to cause the apparatus to return to the upright position when perturbed from the upright position.

Abstract: An integrated system for tracking assets (tools and materials) and personnel associated with a work site. Personnel are equipped with tracking devices having at least geolocation capability. Assets are tagged with RFID tags, which are interrogated at portals, by mobile scanners, or by personnel tracking devices having RFID reading capability. The tag readers and tracking devices are all in communication with a common “information backbone” and all data is delivered to, and processed by, a common command and control subsystem.
