Earlier East Anglia HDD landfalls (ScottishPower's first regional wind farms)
ScottishPower Renewables' earlier East Anglia wind farms used the same horizontal directional drilling method at their landfalls, but with ducts roughly one-third the length of the 1.8km sections now installed for East Anglia TWO, according to project officials.
The earlier projects proved HDD could get export cables under the Suffolk coast without disturbing beaches.
They established the landfall template that East Anglia TWO has now scaled up threefold, yielding a world-record single continuous duct length.
The current record is an escalation of a proven local method, not a brand-new technique — which lowers the technical risk compared with a first-of-kind approach.
