Abstract: Moulding a composite pipe of fibre reinforcement material and a thermosetting resin that shrinks upon curing includes wrapping fibre reinforcement material about the tubular resilient sleeve of a mandrel in a non-expanded state of the sleeve. The mandrel includes an internal support structure for the sleeve which is reversibly expandable in diameter between the non-expanded state. The sleeve is internally supported by the internal support structure and an expanded state by application of an internal pressure to the sleeve. The mandrel with the fibre reinforcement material wrapped about the sleeve is accommodated in a bore of a mould. Seal members provide a closed annulus that can be evacuated. A thermosetting resin that shrinks upon curing is introduced into the closed annulus. A pressurizing fluid is supplied to the mandrel to internally pressurize the sleeve to cause diametrical expansion into the expanded state thereof whilst curing of the thermosetting resin.

Abstract: In the installation of a rotor blade in horizontal orientation to the hub of a horizontal axis offshore wind turbine, use is made of a blade motion synchronization and positioning device, which comprises a wind turbine coupler, a blade coupler, a motion arm between the wind turbine coupler and the blade coupler, and a controllable motion arm actuator assembly. The method includes bringing and maintaining the blade coupler in a motion compensated receiving position, wherein the arm is operated to compensate for sea state and/or wind induced tower top motion. In receiving position, the coupler is coupled to the blade that is suspended from a crane. The actuator assembly is then operated to gradually bring, and then maintain, the coupled blade in a horizontal motion that is synchronized with tower top motion, and to displace the coupled blade root into a pre-mounting position.
