South Hook LNG terminal is an LNG regasification terminal near Milford Haven and is the largest LNG terminal in Europe. Together with the smaller Dragon LNG terminal it can handle up to 25% of the UK's gas requirement. The first tanker docked on 20 March 2009.
The project was announced in April 2003. The terminal was located at the former Esso refinery at South Hook.
The terminal is built to store and re-gasify liquefied natural gas imported from the Qatargas 2 LNG plant in Qatar. in the five storage tanks located onsite. The large tanks are each 94 metres in diameter and 31 metres high, rising another 12 metres to the top. This makes a tank's volume roughly equivalent to that of Albert Hall. The regasified natural gas is to be fed through the South Wales Gas Pipeline to the national gas network at Tirley, Gloucestershire.
The terminal is owned and operated by the South Hook LNG Terminal Company Ltd, a joint venture between Qatar Petroleum LNG Services (QG II) Ltd. (67.5%), ExxonMobil Qatargas (II) Terminal Company Ltd. (24.15%) and ELF Petroleum UK Limited (8.35%).
