Background: First US shale gas arrives at Ineos plant in Scotlandpublished at 12:04 British Summer Time 29 September 2016
The first shipment of US shale gas to be delivered to the UK remains anchored in the Firth of Forth, unable to dock because of strong winds.
It arrived amid a fierce debate about the future of fracking in Scotland and the rest of the UK.
The tanker, carrying 27,500m3 of ethane from US shale fields, is bound for the Grangemouth petrochemicals plant owned by Ineos.
Ineos said the gas would secure the future of the plant's workforce.
