The PNG LNG project consists of an 850-kilometre onshore and offshore pipeline that will transport gas from the Hides, Angore and Juha fields, as well as associated gas from the operating Kutubu, Agogo, Gobe and Moran oil fields in the Southern Highlands and the Western provinces.
The gas will be treated at a plant at Hides before being piped to the liquefaction plant near Port Moresby.
PNG Public Enterprises Minister Arthur Somare said the arrival of the first shipment of pipes was an important occasion in the development and progress of the 6.6 million tonne per annum project.
He added that even though the project was in the early stages of execution, the country was benefiting from the investment with 3000 PNG citizens employed in early works activity.
PNG LNG is scheduled to start producing from 2014 and is expected to deliver more than 9 trillion cubic feet of gas over its 30-year life.
Partners in the project are operator ExxonMobil (33.2%), Oil Search (29%), IPBC (16.6%), Santos (13.5%), Nippon Oil (4.7%), MRDC (2.8%) and Petromin (0.2%).
