There is provided a wind turbine blade extending longitudinally in a spanwise direction between a root end and a tip end, and transversely in a chordwise direction between a 5 leading edge and a trailing edge. The wind turbine blade comprises an outer shell defining a substantially hollow interior, and a shear web arranged inside the outer shell and extending longitudinally in the spanwise direction. The shear web comprises an elongate web panel and a mounting flange extending along a longitudinal edge of the web panel, the mounting flange comprising an inboard end portion defining a root end of 10 the mounting flange and an outboard portion defining a tip end of the mounting flange. The outboard portion extends along a majority of the length of the elongate web panel. The inboard end portion of the mounting flange is bonded to an inner surface of the blade shell by a first adhesive, and the outboard portion of the mounting flange is bonded to the inner surface of the blade shell by a second adhesive. The first adhesive has a 15 lower elastic modulus than the second adhesive, and/or a chordwise width of the inboard end portion of the mounting flange is enlarged in comparison to a chordwise width of the outboard portion of the mounting flange adjacent to the inboard end portion.

A buoy, preferably for a wave energy converter system, comprises a central portion; and one or a plurality of buoyancy blocks connected, directly or indirectly, to the central portion. By providing the central portion with a bell mouth opening and attachment means for a wire or rope, a buoy with improved characteristics is provided.

A method of producing a wind turbine rotor blade. The wind turbine rotor blade has at least an inner blade portion and an outer blade portion, as well as a connecting element. The inner blade portion is wound on a winding form having a first and a second winding portion. The first and second winding portions are releasably fixed to each other by way of a screw connection. The second winding portion is of a conical configuration so that after winding of the inner blade portion a sleeve is produced at an end of the inner blade portion.

A wind turbine composite laminate component and method for producing it is disclosed as initially assembling a laminated structure having at least two reinforced layers and a plurality of interleaf layers positioned adjacent to one of the at least two reinforced layers. Then placing the laminated structure into a mold where resin is sequentially and independently transferred into each of the plurality of interleaf layers. Then curing the transferred resin in the laminated structure to form a composite laminate component having the at least two reinforced layers, the plurality of interleaf layers, and cured resin.

A method using machine learned, scenario based control heuristics including: providing a simulation model for predicting a system state vector of the dynamical system in time based on a current scenario parameter vector and a control vector; using a Model Predictive Control, MPC, algorithm to provide the control vector during a simulation of the dynamical system using the simulation model for different scenario parameter vectors and initial system state vectors; calculating a scenario parameter vector and initial system state vector a resulting optimal control value by the MPC algorithm; generating machine learned control heuristics approximating the relationship between the corresponding scenario parameter vector and the initial system state vector for the resulting optimal control value using a machine learning algorithm; and using the generated machine learned control heuristics to control the complex dynamical system modelled by the simulation model.
