Gorgon is Australia’s largest resources project with an estimated cost of $43 billion. Approximately 40 trillion cubic feet of natural gas will be extracted from the Gorgon and Janz gas fields and transported to Barrow Island for processing at the LNG Plant. Thiess is the Project sponsor in the Thiess Decmil Kentz Joint Venture (TDK JV), which is responsible for the design and construction of the Gorgon Construction Village.
The project involves the engineering, procurement and construction of the Gorgon Construction Village to accommodate 3300 persons.
The project site is designated as an Area D Category 2 cyclone area with all buildings rated importance level 4. The village is designed as a safe haven such that it is not necessary to evacuate employees from Barrow Island during cyclone events.
Accommodation is provided in 10 two storey accommodation clusters situated radially around the perimeter of the village plot. The Central Facilities comprising kitchen/diners, wet messes, gymnasiums and other recreational facilities are located on the inside of the accommodation clusters. The utilities include installation of a Bridging Power Station and Bridging Waste Water Treatment Plant located at the LNG Plant site approximately 4km from the Village.
Key Features of the village design include:
- Adopted layout has reduced the necessary land take to minimise impact on flora and fauna
- Accommodation buildings orientated such that the ends of each accommodation wing face the external perimeter. This assists with shielding fauna from light and noise pollution
- The layout of the accommodation buildings protects the inner recreational facilities from wind
- By placing the recreational facilities on the inside of the accommodation buildings and providing an external perimeter road, there is no interface between pedestrian and vehicular traffic
- The layout provides for future expansion of the village for an additional 700 persons.
The accommodation modules are being fabricated in Thailand prior to being shipped to Fremantle where customs and the Australian Quarantine and Inspection Service clearance is obtained. The modules are then transported to Barrow Island by barge. The Central Facilities buildings are being fabricated in Perth.
Stringent environmental quarantine regulations apply to all buildings, materials and equipment introduced to Barrow Island. The requirements include thorough cleaning and disinfection treatment of all items prior to transportation. After treatment, small items are placed in shipping containers and larger items such as building modules and plant are shrink wrapped to prevent contamination during transport. Shipping to Barrow Island is carried out by barges departing from both Perth and Dampier.
Barrow Island is listed as an ‘A’ Class nature reserve with many unique species native to the island. The marine environment around Barrow Island is part of the Montebello – Barrow Island marine conservation reserves, which comprise a wide range of habitats and extremely high marine bio-diversity.
