Ocean energy is a relevant source of clean renewable energy, and as it is still facing challenges related to its above grid-parity costs, tariffs intended to support in a structured and coherent way are of great relevance and potential impact. The logistics and marine operations required for installing and maintaining these systems are major cost drivers of marine renewable energy projects.…

This paper presents a techno-economic assessment of hydrokinetic energy of Cozumel Island, where ocean currents have been detected, but tourist activities are paramount. The main objective of this research is to identify devices that have been used to harvest hydrokinetic power elsewhere and perform an economic analysis as to their implementation in the Mexican Caribbean. First, the energy…

This paper outlines the learning process undertaken during development of the Oyster® technology by Aquamarine Power, a leader in the wave energy industry. The first generation prototype of the Oyster Wave Energy Converter has operated for more than 6000 hours offshore, enabling significant improvements in the forecast power capture and efficiency of the second-generation device. The…

Following a sequential development path with growing model size Wavebob has in recent years gained valuable experience during large scale sea trials. For the important advancement from sea going models to full scale demonstration of pre-commercial prototypes a transition in the development process is required.
The implemented systems engineering approach enables Wavebob to effectively…

This paper provides an overview of the UKERC technology roadmap and its proposed internationalization. It describes a route for mobilizing the wave and tidal energy community down a deployment pathway towards targets in 2020.
The roadmap is aimed at providing a focused and coherent approach to technology development in the ocean energy sector, whilst taking into account the needs of…

Authors have been developing a pure mechanical wave power generation system. The principle of the system is the application of the gyroscopic moment produced by the rotation of large flywheels and the swing of a float excited by wave motion. This paper presents the principle of the system, the developing process of prototype systems and their test results. It was confirmed that the system has…

The Energy Systems Research Unit within the Department of Mechanical Engineering at the University of Strathclyde has developed a novel contra-rotating tidal turbine (CoRMaT). A series of tank and sea tests have led to the development and deployment of a small stand-alone next generation tidal turbine. Novel aspects of this turbine include its single point compliant mooring system, direct…

Marine renewable energy is still in its infancy and poses serious challenges due to the harsh marine conditions encountered for wave or tidal installations and the survivability of devices. Geophysical and hydrodynamic initial site surveys need to be able to provide repeatable, reliable, and economical solutions. An oscillating water column wave energy converter is to be installed on the west…

A number of tidal projects with different design, sizes and conceptual approaches, have been developed in recent years. While the technology has proven to be effective in converting tidal streams into electric energy, the economic viability is still far from being achieved due to unforeseen complications following the installation of the devices.
In this paper, the authors provide an…

After nearly two decades of development and over 20,000 hours of real-sea 1:4.5 scale testing, Wave Dragon have encountered and solved a considerable number of issues and learned to optimise the control of our device in a vast range of situations and conditions.
The next stage of realisation is to deploy a full scale (7MW) unit in UK Waters; the application for formal consents were made…

While there have been numerous pilot projects with different wave energy devices, the commercial application of wave energy will see the technology installed in more diverse locations. Their deployment has the potential to conflict with other, perhaps already established, use of both the space in which wave energy devices are likely to be best situated and the surrounding areas which might…

This paper describes a development and evaluation protocol that has been specifically adapted for the advancement of wave energy devices. The basis of the schedule is similar to that established by NASA and widely used by many engineering research establishments in other fields. It is geared towards the actual converter evolution and improvement rather than any of the equally important generic…

This paper presents the hydraulic circuit of a new wave energy converter (WEC) design, the MGR. The MGR, due to its working principle, is a hydraulic circuit indeed. The MGR is a near shore submerged converter that takes advantage of the oscillating water column created by the wave when it passes on the converter's platform. The wave column pushes the platform, transmitting the force to a…

The project covers a demonstration of the Wavepiston wave energy concept. Numerical tools for estimation of structural design loads and absorbed power for the concept were developed, together with a tool to model the motion of the complete string structure. A 1:2 scale installation was designed, built and installed in the North Sea. With several iterations made on the detailed design during…

As preparation for deployment of the 1:3 scale WEC, a 1:9 scale system has been developed designed and build.
As test site for the 1:9 model the test site at Nissum Bredning was chosen. The waters at Nissum Bredning are not as energetic as waves in the North Sea. Thus, Nissum Bredning is almost an ideal location for a scaled down test to validate the future 1:3 model.
The 1:9…

Wave Star A/S has produced and installed a test and demonstration Wave Energy Converter (WEC) by Roshage pier near Hanstholm at the west coast of Denmark. The test unit is a prototype/test section of a complete commercial WEC. Only a few days after the installation, which took place in September 2009, the first storm with wind speeds above 30 m/s passed. During the winter more storms have…

Whilst a number of methods exist for the analysis of site availability and weather downtime via metocean exceedance, there is little available for the detailed analysis of holistic marine energy installation projects. Given the magnitude of expenditure relating to the installation phase of marine energy extraction it is essential that significant cost reduction is achieved in this area. This…
