Jackets in background are for the British gas Rough storage project, which were installed over a depleted gas field off the Norfolk coast. Jacket in foreground is for British gas Morcambe bay project off Blackpool, cant remember but I think we built 2 or 3 of them. A 60 inch gas pipe was buried under the ground from Blackpool to the Rough field off Norfolk to store surplus gas produced during the summer from Morcambe bay and was used during winter when demand was higher than which was available. Still in use to this day I believe.
