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.

Peraza and Horne
Knowledge gaps exist in the collective effort to quantify risks and impacts of fish-turbine interactions. Empirical data and modeling studies have characterized stages of fish approach and pass through hydrokinetic turbines, but there has not been a comprehensive model that quantifies conditional occurrence probabilities of fish approaching and then interacting with a turbine in sequential…

Sound generated by marine energy (ME) installations in the ocean environment remains a particular concern for environmental permitting despite the limited evidence showing low levels of ME sounds relative to other anthropogenic sounds. In an effort to increase understanding of potential environmental effects of marine energy projects and help reduce barriers to marine energy deployments, a new…

Public acceptance of offshore wind development projects is critical to successfully advancing and accelerating the US energy transition. A newly developed geo-data engagement platform has been designed to help operators and regulators manage the rapidly growing volumes of complex geo-data needed to plan, design, and construct offshore wind farms; this same platform can also be used to build…

Atlantic Shores Offshore Wind is developing one of the largest offshore wind energy projects along the U.S. East Coast. Given the large lease area covering 741 km2 and with minimal pre-existing geophysical, geotechnical, environmental, and marine archaeological data availability when the lease was awarded, significant front-end efforts were required to complete project design and…

Peralta et al.
The cyclic soil behavior of North Sea clays and silica sands have been well-documented (Andersen 2004, 2009, etc), and have been used globally to develop soil models and design foundations for structures subjected to cyclic wave loading. The recent development of offshore wind farms within the Atlantic Offshore Continental Shelf (OCS) in the U.S. have prompted the large-scale design of fixed-…

This study presents site-specific CPT-based correlation relationships for preconsolidation pressure, undrained shear strength, relative density and effective friction angle, developed for geotechnical characterization of foundation zone sediments at the Atlantic Shores offshore wind farm development. Results of laboratory geotechnical tests on samples from 49 soil borings performed at the…

This study illustrates a ground model approach used to characterize the complex site conditions within the Atlantic Shores Offshore Wind Farm Lease Area. The ground model is the result of the integration of geophysical, geological, geotechnical, and benthic (environmental) data to evaluate marine geohazards and summarize seafloor and sub-seafloor conditions. The ground model is provided in a…

At present, China's marine energy industry is still in its infancy, but there is no doubt that the development of this industry will help China to achieve sustainable development. Therefore, effective policies are needed to promote the industrialization of the industry as soon as possible. This paper systematically consulted the relevant information on the research and development of marine…

Marine renewable energy has the characteristics of green and clean, wide distribution, nearby consumption, accurate prediction, and customization on demand. It can provide green energy solutions according to the needs of islands, ocean economic development, and energy consumption of offshore equipment. China has an excellent marine renewable energy resource. Facing great pressure on climate…

In this paper, we report on a newly developed 34 GHz radar system and its field application in the wind energy testing site WINSENT on the Swabian Alb (Germany). The envisaged sensor system addresses the early detection of birds for a bird-friendly wind turbine operation. In this way, wind turbines could be adaptively controlled to reduce the collision risk of endangered species. Besides the…

Knowledge of the movement and behaviour of birds and bats around turbines in the offshore marine environment is critical for assessing the environmental impacts of offshore wind developments in the eastern USA. To address the problem of gathering high-quality, long-term data on these species in this remote environment, we designed a multi-sensor system that was recently deployed for 6 months…

In 2020-2022 a select group of Irish educators, marine renewable energy proponents and sustainability stakeholders entered into dialogue with a view to enhancing post-primary educational resources. The paucity of educational resources in this field was highlighted, most notably Irish language resources. This dialogue led to the development and piloting of a bilingual (Irish and English) cross-…

As interest in renewable energy grows, marine energy (ME) technologies will continue to play a growing role in reaching our nation's clean energy objectives. As it is still a nascent industry, developing a ME workforce will require a wide range of expertise and tight competition with other energy sectors. The industry needs to attract and train talent to help develop the workforce pipeline.…

This chapter examines underwater noise measurements recorded within and outside operating offshore wind farms consisting of 6.3 MW and 8.3 MW turbines, respectively. Each wind farm had multiple hydrophones recording simultaneously with the nearest being located 70–100 m from a turbine, while the furthest was positioned 5 km outside the wind farm. Data were collected over 5 weeks to facilitate…

Collision risks between marine mammals and tidal energy devices are poorly understood and this perceived risk of collision remains a major issue for the in-stream tidal energy industry, regulators, and stakeholders. Without additional information on the level of risk there is a potential constraint on the scale of future tidal energy development. This paper presents the development of a new…

Marine hydrokinetic (MHK) energy is a renewable resource that helps meet growing energy demands, but potential environmental impacts due to site development and device operation have not been fully investigated [1]. Environmental monitoring is used to detect impacts caused by anthropogenic disturbances and is a mandatory requirement of operating licenses in the United States [2]. Because the…

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…

Ocean Renewable Power Company, LLC (ORPC) has successfully completed the OCGen® Module Mooring Project (Project).The Project made a significant step in the development of designs, methodologies and practices related to floating and mooring of marine hydrokinetic (MHK) devices. Importantly for ORPC, the Project provided a sound basis for advancing a technically and commercially viable OCGen®…

The primary goal of the Department of Energy’s Water Power Program is to efficiently develop and utilize the country’s marine hydrokinetic (MHK) and conventional hydropower (CH) resources. The program has recently identified the need to better understand the potential for hydrokinetic energy development within existing canal systems that may already have integrated CH plants. Hydrokinetic (HK…

The marine renewable energy (MRE) industry is no longer brand new, but is not yet established commercially. Researchers have been examining potential environmental risks of MRE development for about a decade now, but there are still limited data from monitoring around wave and in-stream tidal devices to definitively determine what interactions between devices and marine animals/habitats can be…
