Wheatstone LNG project, ARTES goes to Australia
This project is expected to operate for at least 50 years; once operational, Wheatstone LNG will turn Australia into the world's second largest exporter of LNG, and within a decade, could even make the country the world's largest exporter, ahead of Qatar.
Offshore facilities will include well infrastructure, subsea installations and a processing platform in 73 metres of water, 225 kilometres from the coast. The facilities will extract and partially process gas and associated condensate and deliver them onshore via subsea pipelines for further processing. It is planned to have the capacity to produce up to 25 mtpa of LNG. Works will begin onsite in early fourth quarter 2012, with the first output due for export in 2016.
The onshore installation, located at Ashburton North, 12 Km west of Onslow in Western Australia's Pilbara region, is expected to have two LNG trains with a capacity of 4.3 million tonnes per year each, and eventually it could be expanded to 25 million tonnes a year; it will also include a slug-catcher to separate the gas and liquids, LNG and condensate storage, a domestic gas processing plant and marine facilities including a shipping channel, turning basin, Materials Offloading Facility (MOF) and export jetty. It is a major engineering project of a high complexity that requires the contribution of the leading companies on different fields. In particular, the onshore section will be designed and built by Bechtel, one of the biggest Engineering and construction Companies in the world with more than 50,000 employees, revenues of ab. $30 billion and presence in 50 Countries.
Artes Ingegneria will contribute with the waste water treatment plant for the Wheatstone LNG, the second largest resource project in a Australia.
During the past years big changes on the energy market have made the major Oil&Gas companies to reconsider their business. Many of them are pointing towards the development of Natural Gas, whose demand has had an unstoppable growth due to many factors such as the lower exploitation costs and price than other energy resources, and the newly found reserves around the world. Most of the new reserves are offshore fields off the coast. This situation has prompted the construction of facilities destinated to harvest these Natural Gas deposits. An example of this, is the Wheatstone LNG project, which is one of the biggest resource projects in Australia.
Wheatstone LNG, along with other LNG projects in the country, evidences the technology advances achieved after many years in the market. It also represents the cheapest option for North Asian countries, thus they don't have to ship in the gas from the Middle East, Africa and the Caribbean.
The project is being developed by a joint venture in which Chevron owns the 72%. When constructed, the facility will be dedicated to serve the Wheatstone, Lago, Julimar and Brunello offshore gas fields, situated 250 kilometres off the coast in north-west Western Australia, an ideal location given its proximity to all the discovered gas resources in the Western Carnarvon Basin. The main market is constituted by Australia and the Asia-Pacific region, at the moment, about 80 per cent of the initial LNG produced already has been committed to Japan and South Korea.
The Wheatstone LNG project represents one of the bigger projects ever achieved by the Italian Artes Ingegneria. ARTES will provide engineering, fabrication, supply and site supervision of a vast number of waste water treatment packages. The plants will cater both the permanent and the construction facilities of the Complex handling sanitary water from nearly 7,000 people, oily water and the sludge to be dehydrated. Treated waste water, since meeting the most stringent Australian and international standards, will be mostly reused within the complex.
The Wheatstone development is one of Australia's largest resource projects and represents a tremendous growth opportunity for the companies involved, providing another platform to commercialize significant natural gas resources in Australia. This project reinforces Australia as an expanding and reliable supplier of natural gas for the 21st century.
Solutions for mining in New Caledonia
One of the World's largest Nickel mines and processing plants will soon use a waste water treatment plant supplied by BONO Artes. KONIAMBO Nickel, in New Caledonia, will start up in the second half of 2012, the exploitation of a large Nickel and Cobalt mine.
Established near Koné, the county town of New Caledonia's North Province, Koniambo Nickel SAS is presently building a world-class industrial complex which will contribute to making New Caledonia one of the world's largest nickel producers once production reaches full capacity. Thanks to its yet unexploited nickel deposit that is deemed to be one of the most important and of the best quality worldwide, the Company will maintain a long-term, low-cost operation that will comply with sustainable development principles.
Once construction work is finished, Koniambo Nickel will operate a mine, a pyrometallurgical nickel foundry, a power-generating station and other complementary infrastructures, notably a privately-owned deep-water port, an 11-
kilometre land-based conveyor and a seawater desalination plant.
The beginning of ore treatment is planned for the second quarter of 2012 with a gradual increase in power to reach an annual production of 60,000 tonnes of nickel content in 2014. A thorough feasibility study has been made in the past years, leading to a very environment- conscious design of their new ore processing plant. Great attention has been paid towards all water-related problems, to avoid the overexploitation of the existing fresh water sources and any possible pollution to the nearby sea, where a rich bio-environment is present.
Artes Ingegneria (BONO Artes) has been selected for the supply of a complete waste water treatment plant, to neutralise and re-use 150 mc/h of water used to wash the Nickel-rich ores and the effluents of the smelting plant that extracts metal from them.
The whole lot of processing equipment plus the engineering work for the locally-made piping, carpentry and ancillary equipment, have been
supplied: a complete chemical-physical process - with a sequence of coagulation, flocculation, sedimentation, filtration technologies - will guarantee the maximum purity to the obtained clean waters.
Sludge treatment, consisting of thickening and drying processes, completes the supply.
Already installed, this 7,500 msq plant will be commissioned within the 2012, when the new mine and metal processing plant will become operational.
