This thesis demonstrates the importance of understanding a production system, to increase its productivity through preparation and planning. First categorizing the system, second understanding its failure modes. As planning was a major contributor to the offshore failure modes this guided the further research within the field. Investigating what processes planning methods that would be applicable. Four field studies were conducted to collect empirical data throughout 2017, studying the relation between products, processes, layouts, resources and failure modes. Two longitudinal field studies were performed in 2018, investigating the applicability of Takt planning and Last Planner System within the environment of offshore wind construction. The results showed that the offshore wind construction industry could be perceived a hybrid between
standard products as within production and operational similarities to construction. Further, it was possible to standardize the failure modes within this production system through logical network analysis. Planning and controlling these dynamics required investigations of application. The artefact development and evaluation of the planning methods Takt planning, Last Planner System, and location-based scheduling, adapted for offshore wind projects. Results showed that project construction durations can be reduced with 20% through changing the planning methods from current critical path
method practices. The expansion of knowledge challenged the perception of offshore wind construction as a novel hybrid production system. As its similarities with another novel domain in the literature; modular construction became evident. The contributions from this thesis within the offshore wind project context is the categorization and standardization of the failure modes. The contributions to construction community within the overall operations management domain includes the usefulness of Takt planning, Last Planner System, and location-based scheduling in the offshore wind environment
and applicability for modular construction.
