Cooling Water Intake Decommissioning at Methil Power Station, Fife, Scotland
Scottish Power embarked on a significant decommissioning programme, within which EDS were contracted to remove and make safe the cooling water intake system
The coal fired Methil Power Station located on the mouth of the River Leven in North Fife, had been out of service for some time. Scottish Power embarked on a significant decommissioning programme, in which EDS were contracted to remove and ensure the safety of the cooling water intake system.
This comprised of:
- Dismantling and removing the offshore inlet tower and infilling of rock armour to the offshore end of the 9’ diameter inlet culvert
- The installation of a substantial grout plug to the shore side of the inlet culvert.
- The installation of a substantial grout plug to the outfall culvert.
- The infill and reconstruction of the outfall revetment to match the existing sea wall.
The scale of the works was considerable with material quantities in the region of 1300m3 for armour stone, 300m2 of dressed stone to match the sea wall, and 170m3 high grade underwater concrete. Correspondingly the plant required was also of a substantial nature, with the marine plant alone consisting of a 32m spud leg barge, a 25m multicat and a safety boat. Shore side plant included grout pumps and a 25m long reach excavator.
