Abstract
The area north of Mokapu Peninsula, adjacent to Kaneohe Marine Corps Base Hawaii (MCBH), has been utilized by the U.S. Navy and Ocean Power Technologies, Inc. (OPT) for wave energy research since 2002. After a 2 year deployment, a prototype OPT PowerBuoy was recently retrieved from the 30 meter water depth offshore of North Beach at the MCBH. The Hawaii National Marine Renewable Energy Center (HNMREC) at the University of Hawaii, under contract with Department of Energy, desires to expand the present test site to water depths of 100 meters to allow for the testing of other wave energy devices.
Sea Engineering has been contracted by the HNMREC to conduct site investigations in support of the development of the expanded test site. The surveys included multibeam bathymetry, side scan sonar, sub-bottom profiling and remotely operated vehicle (ROV) video. Results of these surveys have been previously submitted as individual survey reports following completion of each survey. This report compiles and describes all of the survey findings, and presents a summary description of the seafloor characteristics of the project site.
