Nuclear sludge retrieval trial
A pioneering new technique to remove sludge from nuclear fuel ponds has been successfully trialled at one of the UK’s largest wet test facilities. The Decommissioning
Alliance (TDA) is tasked with installing equipment to allow operators to safely retrieve debris laying at the bottom
Heavy-duty fl ow meter launched Waste-to-energy sites can now deploy
the new ST51A Biogas Flow Meter from Fluid Components International (FCI), which combines superior
measurement accuracy with high reliability and
dependability in corrosive gases. Organic waste creates a
potent mixture of combustible methane (CH4
), carbon dioxide (CO2 ), water and trace levels of
corrosive hydrogen sulphide (H2S), gas is problematic for many fl ow measuring technologies. The combustible properties of CH4
of fuel ponds at a site operated by the Nuclear Decommissioning Authority (NDA) to safely remove and transport the recovered material for safe, long-term storage. TDA representatives
completed the task by attaching a Bulk
Sludge Retrieval Tool (BSRT), which ultimately acts like an industrial hoover, to a 40m umbilical. The tool retrieved the sludge and then stored it in a safe manner. To test the new way of working, which includes the use of remotely operated vehicles to lock a hinged double boom arm in position, the team trialled the methods at engineering specialists Forth’s Deep Recovery Facility (DRF) in the company’s headquarters at Flimby, in Cumbria.
gas require HazEx safety approvals. In addition the corrosive, sticky nature of the H2
S particles aff ects the
performance and can clog many fl ow sensors, leading
to frequent, labour-intensive cleanings. With its rugged, no-moving
parts thermal dispersion gas mass fl ow sensor, the ST51A Biogas Flow Meter is designed specifi cally for dirty, potentially hazardous biogas processes. It provides system operators with highly accurate and repeatable mass fl ow measurement data.
US OFFSHORE WIND’S FIRST MINI-CTV
US off shore vessel operator, builder, and owner Edison Chouest Off shore (ECO) has launched construction of the US off shore wind industry’s fi rst ever mini-crew transfer vessel (CTV), designed by Chartwell Marine. Set to
begin operating in summer 2024 for Ørsted and its US-based joint venture (JV) partner, Eversource Energy, the CTV will simultaneously accompany the launch of ECO Edison, the fi rst American-built service operation vessel (SOV) announced in April this year. This so-called “daughter craft” onboard the SOV can be deployed to effi ciently manoeuvre crew across the Revolution Wind, South Fork Wind, and Sunrise Wind off shore wind farms under development by the JV.
LARGEST WIND TURBINE IN CENTRAL ASIA
Inverness-based AWS Ocean Energy has commenced sea trials at the European Marine Energy Centre (EMEC) as part of its scientifi c testing programme for its Waveswing wave energy converter. The initial shakedown testing
at EMEC’s Scapa Flow test site in Orkney involved 10 signifi cant lifting, marine or diving operations demonstrating the practical deployment, operation and recovery of the device. This milestone follows successful
testing and preparation at Copland’s Dock in Stromness since January. Since then several weather windows enabled deployment of the anchor and anchor block, umbilical cable and EMEC’s test support buoy, as well as two trial deployments of the Waveswing.
