Boyne Island aluminium smelter

The Boyne Island aluminium smelter is located on Boyne Island,
Queensland, Australia, approximately 20 km south of the port of Gladstone. The smelter has a production capacity of 545,000 tonnes of aluminium per year [cite web

History

Construction of the smelter commenced in 1979 and the plant was officially opened in 1982. The concept of an Aluminium industry in the State of Queensland Australia began in 1957 when the state government and Comalco’s predecessor signed an agreement giving the Company the right to develop a large Bauxite deposit discovered two years earlier at Weipa on the remote far North West coast of the Gulf of Carpentaria by the Company.

The agreement required Comalco to accept a number of obligations, including establishing a plant in Queensland to refine bauxite to alumina and to investigate building an aluminium smelter to smelt alumina to aluminium. The first obligation was fulfilled in 1967 when a consortium by the company commenced operation of the Queensland Alumina Ltd Gladstone refinery.

The economics of establishing a smelter improved dramatically after the discovery within Queensland of a number of new coal fields in the Bowen basin. In 1972 Comalco entered into further agreements with the State giving the Company the right to opt for blocks of power from a new PowerStation to be built at Gladstone. Partly funded by the Australian Government on the condition that a portion of the power would be used for export industry. In 1974 Comalco began detail investigations into a site for an Aluminium smelter in the Gladstone area. The power agreement defined a radius from the PowerStation for the establishment of the plant. A local office was established in Gladstone to conduct site selection, environmental studies and infrastructure requirements.

In 1975 the Company opted for the first block of power. At the time the world aluminium industry was in recession. In August 1977 Comalco had obtained Federal Government, State Government and Calliope Shire environmental approvals and began clearing and preliminary earthworks on the 50 Ha Boyne island smelter site. It was not until 1978 that conditions improved sufficiently for Comalco to commit in principle to the establishment of the Boyne island aluminium smelter. In August 1979 Comalco formed the consortium company to establish the smelter. [ Citation

Initially the consortium comprised American and Japanese participants along with Comalco an Australian company. All participants entered the project through an Australian subsidiary, and are obliged to take the whole of the production of the smelter in proportion to their shareholding. Comalco managed the construction and ongoing operation of the plant. The first aluminium was produced in Feb. 1982 on schedule and within budget. Potline 2 start-up was July 1983 and the smelter officially opened after that. [cite press release

Construction

With approval of the project by the Board the smelter development came under the Smelter Division of Comalco headed by Executive General Manager Mr Jim L Merritt, he formed a team of experienced engineers to manage the design and construction. A wholly owned company Calliope Constructions Ltd (CCL) was formed with Directors; New Projects General Manager Mr Jack M Lees, responsible for the project fruition. Mr Neil M Jacobs Design Manager responsible for technology, plant design and day to day management of design. Mr John B Gray Construction Manager responsible for site selection, environmental, infrastructure and day to day management of construction. [ Citation

In 1974 along with establishment of its local office, field studies began and extensive discussions and negotiations were held with both Local and State Governments and departments. It was therefore possible to define the public facilities needed associated with a Boyne Island smelter site. As a result a new community at Boyne Island / Tannum Sands was proposed. Comalco staff was actively involved in planning services for the new community and much of this was commenced before construction of the smelter itself began in earnest. By the time construction on the smelter site began, housing subdivisions were proceeding with new housing, (eventually nearly 500 homes) access roads, new bridges onto Boyne Island and another built to Tannum Sands, joining the two previous villages, water sewerage, power supplies and phones constructed. Caravan parks and quarters surrounding a new recreation club with sporting facilities initially for the construction workers but eventually for community use were completed. Nearly $40 million was spent by the Company on community facilities.

Reduction of the lead time activities was crucial in getting the project off to a successful start. With the foregoing arrangements Comalco were able to achieve a start on its project some 18 months ahead of competitors with similar plans.

A ‘fast track’ approach was used for the main plant with simultaneous design and construction with multiple contactors. Although carrying out the technology selection and plant criteria development the Company did not have staff to fully carry out detail design and contract supervision, so CCL decided on an arrangement where it retained project management responsibly and sought the services of a widely recognised engineer constructor. International enquiries were called and appointment of IBI made in June 1979, construction commenced on the plant in Oct. 1979. The organisational arrangement was three tiered; CCL as owner’s representative and project managers, the engineer / constructor as agent to CCL and individual contractors and suppliers, all contracts were with CCL.

Over 3700 drawings were prepared, a design staff peak of 150 engineers and draftsmen (at a time before computer aided drawing) with a field staff of 140 engineers and supervisors. 180 installation contracts were let with a peak workforce of 1400 on site in 1981.

The potline buildings were considered the longest buildings in Australia [Citation

First concrete was placed Mar. 1980, first steel June 1980, 132 kv power energised Nov. 1981. For the initial smelter there were 1,500,000 cu m of earthworks, 116,000 cu m of concrete, 20,000 tonnes of steel, 250,000 sq m of sheeting, 1,000 electric motors, 560 km of cables, 50 km of piping and 60 km of cable racking.

The CCL project team placed emphasis on local participation and opportunity for local engineers. Of the capital cost 77% was spent in Australia, 33% in Queensland and 19% in Gladstone.

To ensure a smooth transition from construction to operations Comalco appointed senior management from existing operations under Mr I W Reid and they were in place to assist with commissioning.

As a green fields site the plant was designed for ease of expansion for an ultimate four potline configuration [ cite press release
