    Abstract

    Current offshore wind turbine lifting procedure: -single elements weighing up to hundreds of tonnes and lifted to heights of 100 meters; Current offshore wind turbine lifting procedure: -risks to personnel, assets, and the environment during installation and maintenance interventions. Objectives: -increase safety during offshore lifts; Objectives: -solutions for human-free lifting operations. Methodology: -ranking and selection of most promising concepts based on a multi-criteria decision analysis with 38 survey responses weighting 21 decision criteria; Methodology: -logistics: development of a MATLAB-based code for choosing pre-assembly method to optimise installation time, lifted weight, and number of lifts; Methodology: - connections: high potential of automated bolting and sea fastening solutions to increase safety during transport and speed up the process; Methodology: -guidance and control: design and small-scale test of a multidirectional mechanical guiding element in combination with visual guidance by cameras.
