Abstract: A hoisting arrangement for hoisting an offshore wind turbine blade, comprising a gripper attachment 150 arranged to be connected to the wind turbine blade, comprising a set of cable attachment points 191, 192,193 arranged as a first polygon, a vessel attachment module 194 arranged to be connected to a vessel, comprising a plurality of cable guide elements 190 arranged as a second polygon, a plurality of cables 141, 142, 143, 144 spanned between the cable attachment points and the cable guide elements, and a control system for controlling a position and/or orientation of the gripper attachment within a work space by controlling a spanned length of at least two cables of the plurality of cables between the cable attachment points and the cable guide elements.

Abstract: For powering a vehicle, a high energy density fuel is preferred. However, for example when the high energy fuel is highly concentrated hydrogen peroxide, this fuel may be dangerous to handle; especially when the person handling the fuel is a normal consumer filling a fuel reservoir of his vehicle at a gas station. The present invention therefore provides a vehicle arranged to receive a diluted—and thus safer—fuel, and to density this fuel to a concentrated fuel in low quantities on board for direct use. To this end a fuel densifier is provided in the vehicle arranged for receiving liquid diluted fuel and arranged to provide a concentrated fuel based on the diluted fuel, the concentrated fuel having a higher energy density than the diluted fuel. A power conversion module of the vehicle is arranged to convert the concentrated fuel to kinetic energy for powering the vehicle.
