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.

… The high number of design options and prototyping activity within the wave energy sector indicates that it is in a conceptual stage of development. It therefore inappropriate to narrow the design focus and an effort should be … process, whereby the widest possible parameter space is evaluated based upon the requirements of wave energy extraction. In this preliminary study a model is used to calculate financial merit …

… environment, marine ecosystems, acoustic propagation and marine mammal behaviour. The remit of the project included wave and tidal energy and, unusually for a project of this nature, offshore wind. Wind was included to enable contrasts between levels of industry maturity and scales of deployment, thus providing a wide range of potential case …

… Installation, operations and maintenance costs represent one of the major barriers to the growth of wave and tidal-stream energy projects and a cost that can be significantly reduced in offshore … strategies can help minimise these costs. To achieve realistic and comprehensive estimates of project duration using these tools, it is essential to represent accurately the durations and …

… power assessment, uncertainties arise from model assumptions and the inexact specification of physical and numerical model parameters. Combined, such uncertainties can greatly affect power estimates for a given site. The thesis examines the effects of bed roughness and turbine drag uncertainties on turbine power estimates. An analytic model is developed for transfer of bed friction uncertainty to power extracted from turbines in a strait, representative of a …

… for Wave Energy Convertor (WEC) designers and manufacturers is the efficient conversion of differing wave types into useful motion to produce electricity. The height, period and orientation of waves vary greatly as do their respective power levels [1]. In order to efficiently and cost effectively convert the kinetic energy of wave motion into electrical energy, a Power Take Off (PTO) system must be able to withstand …

… One of the key challenges in marine energy is to achieve funding for commercial-scale project … the necessary capital investment, the expected profit margins, and the corresponding cost of capital. The paper examines this relationship for tidal current schemes and provides a method … de-risk early-stage project initiatives. The possibility to select a preferred ratio of ‘capital investment’ to ‘profit’ widens the circle of potential investors and accelerates the …

… scale model testing is an important development tool, used extensively to study the behaviour of marine devices, vessels and structures in a controlled environment prior to deployment at sea. … renewable energy devices has been published over the past decade, it has limitations in terms of advanced environmental conditions for testing. The body of existing guidance is reviewed, and initial suggestions offered for additional test conditions …

… This paper presents a detailed parametric analysis on various input parameters of two different numerical models, namely Telemac3D and Delft3D, used for the simulation of tidal current flow at potential tidal energy sites in the Pentland Firth in Scotland. The motivation behind this work is to investigate the influence of the input parameters on the above 3D models, as the majority of past research has mainly …

… government and devolved administrations. Attention has been drawn to this resource as a number of locations with high tidal current velocity have recently been leased by the Crown Estate for … velocity is too low for any power generation. However, it has been proposed that a portfolio of diverse sites located around the UK will deliver a firm aggregate output due to the relative phasing of the tidal signal around the coast. This paper analyses whether firm tidal power is feasible …

This … throughout the tank using an ADV. The goal is to provide a comprehensive characterisation of the flow in the tank, in a robust and repeatable manner. These flow parameters are then … measurements for context. The turbulence intensities are normally distributed in the range of 5–11% and integral lengthscales were log-normally distributed over a 0.18–0.41 m range across …

… Tidal turbines encounter a range of unsteady flow conditions, some of which may induce severe load fluctuations. Rotor blades can experience stall delay, load hysteresis and dynamic stall. Yet, the range of flow conditions which cause these effects for a full-scale axial-flow turbine are unclear. In …

… load. We consider a tidal turbine rotor in a shear current at a diameter-based Reynolds number of 2×107. The blades are rigid and can passively pitch. A mass–spring system acts on the spanwise axis of the blade governing the pitch kinematics. The effectiveness of this system is demonstrated with three methodologies: an analytical model based on blade …
