<strong>Review</strong> <strong>of</strong> <strong>Cabling</strong> <strong>Techniques</strong> <strong>and</strong> <strong>Environmental</strong> <strong>Effects</strong> <strong>Applicable</strong> to the Offshore Wind<br />

Farm Industry – Technical Report<br />

Another generation <strong>of</strong> dredging only units have occasionally been used for<br />

cable burial work at inshore locations. These dredging units are large suction<br />

machines which are generally used to excavate large holes in the seabed <strong>and</strong><br />

are more commonly used for seabed levelling <strong>and</strong> dredging activities. Owing<br />

to the imprecise nature <strong>of</strong> their mode <strong>of</strong> operation, scarcity <strong>of</strong> use, <strong>and</strong> because<br />

they have a significant environmental impact, they are considered unlikely to be<br />

used for the burial <strong>of</strong> <strong>of</strong>fshore wind farm cables. They have not, therefore, been<br />

included in the scope <strong>of</strong> review <strong>of</strong> this study.<br />
