Engineering & Construction

Saipem, in a joint venture with other partners, has been involved in numerous projects in Australia including the construction of a 1,500-kilometre gasline from Dampier to Perth, Section II of the gasline from Amadeus Basin to Darwin (from Helling to Buchannan Highway, including an offshoot from Merenee to Alice Springs) and of the 1,380-kilometre Goldfield Gas Pipeline. In 2005, Saipem completed the Bayu Undan-Darwin Gas Pipeline between the Bayu Undan field and the natural gas liquefaction plant at Darwin, while in 2006 it was awarded a contract for the 5-A phase of the project for expanding the pipeline (constructed by Saipem in the 1980s) that connects Dampier to Bunbury, in Western Australia. The contract included the engineering, installation and construction of the work to be carried out before laying a 26-inch, 570-kilometre pipeline, and it was completed in 2008.

In April 2007, Saipem was awarded a contract for the development of the Blacktip offshore oil field. The contract included the engineering, procurement, construction, installation and start-up of a production platform and an underwater pipeline system for transporting hydrocarbons to dry land over a distance of some 108 kilometres. In 2009 installation operations for the project were completed using the Castoro Otto pipe-laying vessel.  

In 2008 work was completed, on behalf of Coogee Resources, on the Montara project, which included carrying out project management activities and the engineering and installation of a pipeline using the Castoro Otto pipe-laying vessel.

In November 2009 Saipem, in a consortium with Leighton Contractors, was awarded an EPC (Engineering, Procurement, Construction) contract by Chevron for the construction of a jetty and associated offshore structures, as part of the Gorgon LNG project.

The contract was for the engineering, procurement, construction and start-up of a jetty and relative offshore structure for the new Chevron Gorgon LNG plant situated on Barrow island, approximately 70 kilometres off the coast of Pilbara in Western Australia. In 2011 work on the contract continued, with operations expected to be completed in 2013. In June 2012, Saipem negotiated a series of variations to the work covered by the contract.

The Gorgon project is a joint venture between the Australian division of Chevron (operator), ExxonMobil and Shell for the development of the Greater Gorgon gas field, situated between 130 and 200 kilometres off the north-west coast of Australia. 

In January 2011, Gladstone LNG Operations Pty Ltd awarded Saipem an EPC contract for the engineering, procurement and construction of a pipeline for transporting gas that will connect the Bowen and Surat Basins, in the area between the towns of Roma and Emerald, in Queensland, to the Gladstone State Development Area (GSDA) on the Coral Sea coast, near the town of Gladstone, Queensland, where an LNG (liquefied natural gas) liquefaction and export plant will be constructed. The pipeline will be entirely buried underground and during its construction measures will be taken to reduce to a minimum the impact of operations on the most environmentally fragile areas and to restore the local vegetation and biodiversity. The work is expected to be completed by the third quarter of 2013, while operations began in 2011.

In January 2012, Saipem signed an EPIC contract with INPEX for the gas pipeline from the Ichthys LNG project. Saipem is contracted to provide the engineering, procurement, construction and installation of an 889-kilometre underwater pipeline with a 42-inch diameter, at a depth of up to 275 metres, that will connect the offshore Central Processing Facility with the land-based treatment plant situated near Darwin. The sea-based operations will be carried out during 2014 using the recently built Castorone pipe-laying vessel, while the recently modernised Semac 1 pipe-laying barge will be used in shallow water.

The Ichthys LNG project is a joint venture between INPEX (76% and project operator) and Total (24%). The gas extracted from the Ichthys deposit, situated in the Browse Basin, approximately 200 kilometres off the coast of Western Australia, will undergo initial treatment directly at the sea-based structure to remove water and extract the condensates. The gas will then be transported to the land-based treatment plant near Darwin along an 889-kilometre underwater pipeline. The Ichthys project will produce 8.4 million tons of LNG (Liquefied Natural Gas) and 1.6 million tons of LPG (Liquefied Petroleum Gas) per year, in addition to approximately 100,000 barrels of condensates per day during the peak production phase.
