This deliverable describes the results of the assessment of the preliminary configuration designs of the LiftWEC concept. It details the ‘Scenario Test Cases’ that were run on certain preliminary configuration designs. Due to delays in development of the operations and maintenance software, as well as the large number of preliminary configurations: the assessment approach was to take the broad category of configurations using standard towing vessels and configurations that would require larger vessels. Details are provided on the representative site, met-ocean resource data, vessel parameter data, technician requirements and cost details. A discussion on the results is included and any operational risk areas identified are consolidated into a series of recommendations for consideration for the baseline configuration designs.
