McGrath et al.
Marine energy encompasses a rapidly advancing group of technologies designed to harness the renewable energy resource in the marine environment. Significant technology developments are ongoing in the general field of marine energy, but specific to this paper in the field of Tidal Energy Convertor (TEC) technology. In order to take advantage of this continuous, and at times stepped, improvement…

Tritech high frequency sonars are used for automatic target detection and tracking around several tidal turbines as part of Environmental Effects Monitoring Programmes (EEMP). Historically, attention has been focused on using this technology to monitor marine mammals but newer installations are extending requirements to include fish. The benefits of using 720 kHz sonars in permanent…

Azzellino et al.
The importance of the study design and the need for comparability of methods has been acknowledged in the context of the environmental impact assessment of the Marine Renewable Energy Sector. The standardization of the EIA process of Marina Renewable Infrastructures is still far to be sorted out and a good deal of variation exists in the considered parameters and receptors as in the methods…

Lieber et al.
Multibeam sonar has emerged as a powerful tool for environmental monitoring of marine renewable energy (MRE) devices. Moving away from manned operations, self-contained multibeam sonar systems may be costly at purchase, but are cost- effective for long-duration, autonomous deployments. However, there is no single multibeam sonar configuration that suits all environments and MRE devices…

Copping and Grear
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…

Grear and Motley
As new renewable energy devices are installed, the environmental impacts must be evaluted. The spinning blades of tidal turbines can potentially injure marine mammals through collision and this risk must be evaluated prior to installing tidal energy. One of the obstacles to fully understanding the effects of turbine impact on these animals is proper modeling of the biological materials. This…

Callaway et al.
Artificial structures such as wave and tidal energy devices provide surfaces and structures that are naturally colonised by marine flora and fauna. Properties of the building material, surface texture and structural complexity of the infrastructure will determine the suitability as a habitat for marine organisms. While it may be desirable to inhibit fouling of some parts of the energy devices…

Brown et al.
Tidal energy extraction offers a highly predictable, reliable energy resource. However, natural flow regimes will be altered by the installation and operation of large scale tidal arrays. Bed morphology, sensitive to changes in tidal flow, will therefore be impacted as a result of feedbacks between tidal arrays and coastal hydrodynamics. This research investigates the impact of large scale…

This presentation on cybersecurity for marine renewable energy systems was presented to the Marine Energy Council on February 18, 2020. It provides an overview of a Pacific Northwest National Laboratory-led project aimed at developing a guidance document that will assist developers and end users with integrating security controls into the operational and enterprise networks of the MRE systems…

The marine renewable energy (MRE) industry is an emerging source of power for marine applications, marine devices, and coastal communities. Developers of MRE systems rely on industrial control systems and information technology to support operations and maintenance activities. The advanced operational and information technology devices used in MRE systems create a pathway for a cyber-threat…

Cavagnaro et al.
Marine renewable energy (MRE) encompasses the harvest of energy from the movement of ocean waters in the form of either currents or waves, as well as temperature and salinity differentials. To date, most MRE development has focused on utility-scale electrical grid generation, but a growing body of work focuses on non-grid applications in the blue economy where MRE could provide power on-site…

Flinn et al.
This paper discusses the principles of risk management in a wide context, including definitions of risk and how diverse types of risk can be compared on a common basis. The paper also provides an overview of how the main processes have been developed in other industries, including discussions of the various methods of quantitative risk assessment, and how standards fit into this. It then…

Khan et al.
Marine energy, especially tidal current and ocean wave resources, bear immense potential for generating renewable power toward meeting global electricity needs. A number of conversion technologies have been successfully demonstrated worldwide and precommercial/commercial deployments are expected to appear in the near future. While electric power utilities foresee renewable technologies as a…

Aquamarine Power Ltd
The experiences and lessons gained on the Oyster 1 project led Aquamarine Power to make some fundamental changes to the design philosophy to improve access and maintenance for Oyster 800. This package of work highlights the lessons learnt on the Oyster 1 project, and documents how these areas were improved for Oyster 800. The report also highlights where the changes made were effective and…

Aquamarine Power Ltd
Throughout the development of the Oyster Technology, Aquamarine Power suffered from mixed experiences of the supply chain and poor component supply. Many of the components were purchased on the understanding that they were fit for purpose in subsea marine environments, and a number of these were not bespoke and may be considered by other wave developers.
Aquamarine Power often had to…

Aquamarine Power Ltd
Oxygen, biological activities, pollution, temperature, salinity, suspended sediments and velocity are the known major factors which affect the corrosion behaviour of materials submerged in sea water.
In this report Aquamarine Power documented the lessons learnt in design through the use of standard off-the-shelf components and materials, and the effect of material grades and…
