Sonardyne System to Monitor North Sea CO2 Leaks

Sonardyne International is taking part in a new Energy Technologies Institute (ETI) project within the Carbon Capture Storage (CCS) program to develop a Carbon Dioxide (CO2) marine and shallow subsurface monitoring system for underground CCS sites in the North Sea. The system will monitor for any CO2 leakage from saline aquifers and offshore storage sites such as oil and gas fields, both active and depleted. The development of a U.K.-based North Sea CCS industry is an important element in the government’s initiative to significantly cut greenhouse gas emissions by 2050, mitigating against

Fugro Leads UK Carbon Capture Project

Fugro GEOS, in partnership with Sonardyne, is leading a three-year, all-British project for the Energy Technologies Institute (ETI) to develop a carbon dioxide (CO2) monitoring system using marine robotics. Valued at £1 million in the first year, the project aims to provide assurance that CO2 stored deep below the seabed in Carbon Capture and Storage (CCS) sites is secure. The safety of such a method is of paramount importance, with feasibility studies currently underway in the U.K. and overseas on a number of CCS projects. A consortium of British multidiscipline partners will examine the

The project, commissioned and funded by the ETI, will develop a monitoring system using marine robotics and Sonardyne’s ALDS to provide assurance that carbon dioxide stored in CCS sites is secure. (Photo: Sonardyne)

(200m resolution) along the coastline or into estuaries. This means the model can simulate storm surges at a very localized level informing risk assessments for coastal planning or insurance.” Developed by HR Wallingford, SMARTtide was originally commissioned and funded by the Energy Technologies Institute (ETI) to identify the most efficient sites for tidal energy converters, tidal arrays or tidal barrage schemes around the U.K. and French coastlines. The model continues to be used for this purpose and can now also be used for storm surge simulation. hrwallingford.com

Offshore Wind Floating TLP Model Tests Complete

Glosten Associates (Glosten) announce that the 3-week scale-model testing of the PelaStar tension-leg platform (TLP) has been completed. The three-week test program was conducted in support of the Offshore Wind Floating Platform Demonstration Project FEED Study awarded to Glosten by Energy Technologies Institute (ETI). The test results are being used to further demonstrate PelaStar’s technical feasibility and to calibrate state-of-the-art software used to design, analyze, and optimize the floating wind turbine system. The 1:50-scale floating wind turbine model was tested in the world

Tidal Energy Modelling Tool Launched

The Energy Technologies Institute (ETI) and HR Wallingford launched a tidal energy modeling tool for use by tidal energy developers to identify the most efficient sites for tidal energy converters, tidal arrays or tidal barrage schemes around the U.K. and French coastlines. The computer program, SMARTtide (Simulated Marine Array Resource Testing), incorporates a 2D hydrodynamic model of the U.K.’s continental shelf and the north-west European coastline. The software will be available to the public from May 21 as a fee-for-service via a portal on HR Wallingford’s website. The data

This follows the successful testing of TGL’s 500kW device, which was also certified by GL RC. The ReDAPT project, commissioned and cofunded by the Energy Technologies Institute, will test the performance of the tidal generator in different operational conditions. Its aim is to increase public and industry confidence in tidal turbine technologies by providing a wide range of environmental impact and performance information, as well as demonstrating a new, reliable

Glosten to Design Floating Offshore Wind Platform

The Glosten Associates, Inc. announced it has been awarded a contract from the U.K.–based Energy Technologies Institute (ETI) for the engineering phase of the floating offshore wind turbine demonstrator using the PelaStar tension leg platform (TLP) foundation system. The $6 million (U.S.), 12-month contract will complete the Front End Engineering Design (FEED) in advance of construction and deployment of a 6 MW demonstration unit off the south coast of the U.K. as early as 2015. Upon completion of the FEED, the ETI is prepared to commit up to $31 million (U.S) to the demonstration project

World's Longest Wind Turbine Blades Development Project

UK's Energy Technologies Institute (ETI) appoints Blade Dynamics to develop technologies for constructing ultra long-length wind turbine blades. Blade Dynamics will construct blades for the ETI of between 80 to 100 metres in length, incorporating carbon fibre rather than conventional fibre glass. This compares with blades now deployed offshore of between 60 to 75 metres in length. The intended end use for the blade technology is on the next generation of large offshore wind turbines currently under development with a capacity of 8 to10MW. This compares with the 5-6MW capacity turbines currently
