This report is an addendum to SAND2013-9040: Methodology for Design and
Economic Analysis of Marine Energy Conversion (MEC) Technologies. This report
describes an Oscillating Water Column Wave Energy Converter reference model
design in a complementary manner to Reference Models 1-4 contained in the above
In this report, a conceptual design for an Oscillating Water Column Wave Energy
Converter (WEC) device appropriate for the modeled reference resource site was
identified, and a detailed backward bent duct buoy (BBDB) device design was
developed using a combination of numerical modeling tools and scaled physical
models. Our team used the methodology in SAND2013-9040 for the economic
analysis that included costs for designing, manufacturing, deploying, and operating
commercial-scale MEC arrays, up to 100 devices. The methodology was applied to
identify key cost drivers and to estimate levelized cost of energy (LCOE) for this
RM6 Oscillating Water Column device in dollars per kilowatt-hour ($/kWh).
Although many costs were difficult to estimate at this time due to the lack of
operational experience, the main contribution of this work was to disseminate a
detailed set of methodologies and models that allow for an initial cost analysis of this

Efficiency & Renewable Energy (EERE). Sandia National Laboratories, the lead in
this effort, collaborated with partners from National Laboratories, industry, and
universities to design and test this reference model.
