This site-wide search returns results for all documents and events in Tethys Engineering, prioritizing the best matches. Partial word matches are returned (e.g. "engineer" finds "engineering"), but every entered term must be found. If you don't find any results, try reducing the number of words entered or removing special characters. Filters to the right can help narrow your search. Tethys Engineering features an integrated search with other marine renewable energy databases in PRIMRE - click the buttons below "Showing Results for" to search other integrated databases.

… lack of infrastructure to support in-water testing. A small number of established permanent test sites exist, but these sites are often prohibitively expensive to build and operate. The … objective of this project was to develop a concept design for a small deployable marine energy test system. The solution described is a self-contained system with the capability to monitor the local environmental conditions, host and test one small wave energy converter (typically <1-kW power generation), and collect and store …

Ziogos et al.
This paper presents results from research which aims to establish better understanding of the shear resistance of rock-steel interfaces to develop enhanced gravity foundations for tidal energy generators. Findings from laboratory testing are presented along with issues arising from field visits at sites with high tidal energy potential in Scotland. Direct shear box tests were carried out on…

Want et al.
A novel system was developed to deploy settlement panels to monitor biofouling growth in situ and evaluate antifouling coatings at depths representative of operational conditions of full-scale marine renewable energy devices. Biofouling loading, species diversity, and succession were assessed at depths ranging from 25-40 m at four tests sites in Orkney (UK) featuring extreme wave and…

This chapter talks about marine energy capturing. It introduces the physics of ocean waves and tidal streams as a prelude to explaining the principles underlying some of today's most promising developments. Wave measurement buoys are used by marine energy organisations to provide the continuous, long‐term, data required by wave energy developers as they deploy their machines offshore. Wave…

Quadcopter drones are readily available off-the-shelf; they are easily portable, low cost and low risk. Therefore, compared to traditional methods such as vessel-based current surveys, measurement of currents using drones is attractive both financially and logistically. Drones can record video of the water surface and then currents determined using velocimetry techniques. This approach has…

ROV use in new and emerging areas including marine renewable energy and seafloor characterization in high flow environment is growing. With the downturn in the oil and gas industry, there is a reduced level of activity in the marine ROV operations related to the industry. Cost reduction and improved capabilities have become the priorities for ROV development. In this context, the current state…
