10 Moray OWF Jackets Arrive at Port of Nigg on OHT’s Hawk
Moray Offshore Windfarm (East) Ltd (known as ‘Moray East’) welcomed the arrival of OHT’s heavy transport vessel, “Hawk” at Global Energy’s facility at the Port of Nigg on Monday. The vessel arrived with nine wind turbine and one offshore substation platform substructures or ‘jackets’, each standing 75m – 80m high.
The jackets will be offloaded at Nigg, where they will undergo the final preparations before they are loaded onto the jack-up vessel “Seajacks Scylla” which will undertake their installation at sea, more than 25km from shore in the Moray Firth. UK- based Seajacks Ltd has been subcontracted for installation vessel provision.
Moray East has appointed a consortium of DEME and Smulders for designing, manufacturing and installing the jackets; in turn Global Energy has been subcontracted to provide facilities at the Port of Nigg to support the installation works, and Offshore Heavy Transport (OHT) has been subcontracted for shipping vessel provision.
The Port of Nigg and the Port of Cromarty Firth are providing the onshore facilities from which the offshore installation work will be undertaken.
A total of 103 jackets are being installed in the Moray Firth to provide foundations for 100 offshore wind turbine generators and three offshore substation platforms.
To get the electricity to customers onshore, three subsea cables will be laid which will connect the three offshore substations with underground onshore cables at Inverboyndie, and thence to the new substation currently under construction south of New Deer, which will make the power generated available to consumers via the National Grid.
When complete the facility will be capable of meeting the needs of more than 950 000 homes.
