This site-wide search returns results for all documents, events, metadata, and stories in Tethys, prioritizing the best matches. Partial word matches are returned (e.g. "environment" finds "environmental"), 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 now features an integrated search with other marine renewable energy databases in PRIMRE - click the buttons below "Showing Results for" to search other integrated databases.

As tidal turbine deployments continue at test sites and in commercial areas, the potential risk for injury or death of marine mammals from colliding with rotating turbine blades continues to confound efficient consenting (permitting) of devices. Direct observation of collisions is technically very challenging and costly. Estimates of collision risk to date have been derived from complex…

This research examined the feasibility of developing small-scale OTEC (3-10 MW) in U.S. waters through case studies in four locations (i.e., Hawaii, Puerto Rico, St. Croix, and Guam). In addition to talking to local leaders and experts in OTEC development and processes, we examined the likely environmental effects that will drive permitting (consenting) and licensing processes in the U.S. and…

Hutchison and Copping
This report outlines a coordinated action plan aimed at reducing the scientific uncertainty associated with collision risk of marine animals and tidal turbines. This plan includes steps to take toward resolving the challenging issue of decreasing scientific uncertainty, but is unlikely to completely solve the problem. The content of this report was derived from the involvement of experts…

Floating offshore wind farms have been proposed in the deep waters off the U.S. west coast and Hawaii to provide renewable energy to coastal populations.Anchoring floating wind platforms to the seabed requires multiple mooring lines that pass through the water column from platforms at the surface to the sea floor. Electrical cables also will be draped in the water column between wind platforms…

Carlson et al.
The deployment of tidal turbines in coastal waters raises questions about the potential risk to marine animals from strike by rotating blades. Of particular concern are marine mammals that are already facing threats from other human activities as well as climate change. Regulators in the US who are charged with permitting the installation of tidal turbines have sought additional information to…

Copping et al.
Surface-placed wave energy converters, floating tidal turbines, and floating offshore wind platforms all require anchoring to the seabed with multiple mooring lines and electrical cables passing through the water column, from near the sea surface to the sea floor. Concerns have been raised that large whales may collide with and/or become entangled in lines and cables from renewable energy…

Anderson et al.
Possible environmental effects of marine and hydrokinetic (MHK) energy development are not well understood, and yet regulatory agencies are required to make decisions in spite of substantial uncertainty about environmental impacts and their long-term effects. An understanding of risk associated with likely interactions between MHK installations and aquatic receptors, including animals,…

Commercial interest in developing floating wind energy in the deep waters of the Pacific Outer Continental Shelf has raised questions about whales and other large cetaceans potentially encountering the mooring lines and electrical cables from a floating offshore wind farm. The BOEM Pacific Region asked the Pacific Northwest National Laboratory to create an animated simulation of a humpback…

The deployment and operation of a floating tidal technology in the United States require assessing environmental conditions and satisfying all environmental permitting requirements. Two locations in the United States are chosen to evaluate the potential for deployment of the Orbital Marine Power Ltd. floating technology: San Juan Islands (Washington) and Western Passage (Maine). This report…

Copping et al.
Marine renewable energy (MRE) is under development in many coastal nations, adding to the portfolio of low carbon energy sources that power national electricity grids as well as off-grid uses in isolated areas and at sea. Progress in establishing the MRE industry, largely wave and tidal energy, has been slowed in part due to uncertainty about environmental risks of these devices, including…

Grays Harbor Wind LLC (GHW) is proposing to develop a floating offshore wind farm offshore of west Grays Harbor County, Washington (Grays Harbor). The proposed GHW Offshore Wind Project (Project) would entail construction, installation and operation of a 1,000-megawatt (MW) offshore wind farm consisting of approximately 75 floating units, each containing a floating foundation and wind turbine…

Copping et al.
The potential risk to marine mammals colliding with turbines is one of the primary environmental concerns slowing tidal energy development in the US and Europe. Few field observations of interactions between marine animals and tidal turbines have been reported [1], necessitating supplemental risk analyses and modeling to help fill the gap. This study provides a surrogate measure of the…

Hemery et al.
MARINE renewable energy (MRE) developments, such as those harvesting wave or tidal energy, will need to grow towards large-scale arrays for the sector to successfully contribute toward the portfolio of sustainable energy alternatives and fight global climate change. However, this growth must be accompanied by the investigation of potential environmental effects at larger scales, and will…

Copping et al.
Commercial development of tidal stream energy is hampered by technical and financial challenges, and impeded by uncertainty about potential environmental effects that drive environmental risk assessments and permitting (consenting) processes. The effect of greatest concern for operational tidal stream energy devices is the potential for marine animals to collide with turbine blades, resulting…

Many marine mammal populations worldwide are in decline due to stresses from climate change and interactions with anthropogenic activities such as fishing, coastal construction petroleum extraction, and commercial shipping. The advent of the marine renewable energy industry has raised questions, particularly for tidal turbines. However, it is technically very difficult to observe close…

The Marine Animal Alert System (MAAS) was developed by the Pacific Northwest National Laboratory as an element of compliance monitoring to support deployment of marine hydrokinetic energy devices. An initial focus is prototype tidal turbines to be deployed in Puget Sound in Washington State. The MAAS will help manage the risk of injury or mortality to marine animals from blade strike or…

In late 2011, representatives of the U.S. offshore wind industry approached the U.S. Department of Energy Wind and Waterpower Program staff to express concern that regulatory requirements to protect North Atlantic right whales (NARWs) are likely to impose stringent limitations on the process of offshore wind installation off the Atlantic Coast. This project was designed to evaluate the…

Power generated from marine energy devices, including those that harvest power from the waves and tides, has the potential to help meet the low-carbon energy needs of many coastal nations. However, these devices, and their related mooring lines, anchoring and buoyancy systems, and power export cables are still under development, resulting in a lack of understanding of potential environmental…
