As part of a broader research on offshore wind logistics optimization, this paper focuses on how digitalization can be further developed to support logistics in the particular domain of offshore wind farm construction, as well as Operations and Maintenance (O&M). This paper analyzes five major digitalization potentials: the use of unmanned systems, 3D printing, motion sensors, big data techniques and LiDAR usage. The term Industrial Digitalization Technologies (IDT) summarizes these potentials. This contribution provides an initial mixed method analysis on enhanced offshore wind efficiency. Initial frameworks based on in-depth literature analysis on the one hand and on experimental break-even calculations on the other, are provided. This paper's outcome shows that unmanned systems provide the by far largest cost-saving potential.

The purpose of this study is to propose scheduling and operations improvements for logistics to support offshore wind construction. The study conducts a literature review of scientific studies on the offshore wind logistics. Based on this review, a definition of offshore wind logistics during construction phase is proposed. It can be seen that only a few studies have focused on offshore wind logistics (except installation vessel) duringwind turbine construction phase. To help closing this gap, a model is proposed to evaluate and select offshore logistics spread in order to support construction phase. Results on simulations show that logistics spread efficiency varies depending on the season, distance to shore and geographical location. Adaptation and combination of logistics concepts may be necessary to achieve best cost efficiency. The resul...

Particularly during wind turbine construction, vessels are intensively used. However, no study has been found to evaluate logistics costs during this particular turbine construction phase. Objective: In order to close this gap, this paper aims to propose an Offshore Logistics Cost (OLC) framework, evaluate OLC impact on total cost and identify recommendations to reduce this impact. Methodology: This study considers two quantitative approaches to evaluate OLC share. First quantitative approach is based on cost information found in twenty related studies from literature. Second quantitative approach was developed in two steps. A first step is a bottom up calculation model. This model performs OLC calculations for each scenario identified. In a second step, OLC results are used as input to two existing calculation models: National Renewable Energy Laboratory (NREL) simplified mo...

Based on some existing principles from optimizing production techniques, this paper proposes an ad hoc model to measure and improve efficiency for logistics during offshore wind farms construction.
