The Able Marine Energy Park Development Consent Order 2014

Construction of the quay

4.—(1) The licence holder is permitted to construct the quay (Work No. 1) and carry out associated land reclamation within the quay limits and according to the following specification:—

(a) no more than 650 tubular and 1300 sheet steel perimeter piles may be driven into the bed of the estuary to form the external face of the quay, where such piles are to be installed from named vessels moored in the estuary;

(b) 2 return walls may be constructed between the ends of the quay and the existing flood defence wall, comprising no more than 500 tubular and 1000 sheet piles driven into the bed of the estuary from named vessels and also earthwork revetments with no more than 100,000 tonnes of rock armour protection, such revetments and rock armour to be constructed using land-based plant;

(c) no more than 750 flap anchor piles may be fixed to the landward face of the perimeter piles and seated in a trench on the bed of the estuary, to be installed from named vessels moored in the estuary;

(d) no more than 100 steel anchor piles may be driven into the bed of the estuary and fixed to perimeter piles, to be installed from named vessels moored in the estuary;

(e) the area of estuary approximately 50 metres landward of the quay perimeter piles may be reclaimed by depositing marine dredged sands and gravels from named vessels using rainbowing techniques;

(f) the remaining area of estuary enclosed by the quay perimeter piles and the two return walls may be reclaimed using marine dredged sands and gravels by constructing two granular dams that extend from the existing flood defence wall to the area reclaimed under paragraph (e), so that the dams divide the remaining reclaim area into three approximately equal cells, after which named vessels are to pump fluidised granular material into each cell in sequence, allowing estuarine water that is retained within each cell to overflow the dams as the fluidised material is deposited and settles within the cell, such activity to continue until all cells attain their design levels; and

(g) steel plates may be attached to the perimeter piles by welding and bolting, and then a fender may be attached to each steel plate by bolts, all such works being undertaken from a man basket suspended from a crane located on land.

(2) Drainage and disposal outfalls and cooling water outfalls may be incorporated into the quay but for the avoidance of doubt the use of these outfalls is not licensed by this Schedule.

(3) Monitoring equipment fixed to buoys must be deployed at locations in the estuary before, during and after the piling works permitted by sub-paragraph (1) in accordance with the marine environmental management and monitoring plan.
