M3 Wave DMP/APEX WEC Survival Test Report

Abstract

This survival test report for the Delos-Reyes Morrow Pressure Device (DMP), commercialized by M3 Wave LLC as "APEX," summarizes the key tank test data, numerical model results, input test conditions (both numerical and tank testing), and crosses these items with three designs of the APEX wave energy converter. The baseline design of APEX is included, in addition to a minimalistic caisson design (aka 'the skeleton'), and variations of the APEX design where elevation off of the seabed is achieved. In general, sediment transport mitigation is a trade-off with other design factors, for example: while a minimalistic caisson helps reduce local scour for many wave conditions, it comes at a cost for bag connection failure/weakening.
