This project represents the largest maritime structure in Australia to undergo environmentally controlled disposal.
Demolition of the 10,000 tonne Ex-HMAS Sirius was a complex, multi-faceted project involving a large scale heavy lift in addition to all other aspects of disposal and demolition with significant additional complexities.
The Ex-HMAS Sirius was built as a double hulled commercial product tanker, MV Delos, and purchased by the Commonwealth Government on 3 June 2004. During its life, the ship underwent modifications for underway replenishment. In addition, a flight deck was fitted for helicopter operations.
This vessel had the capacity to carry over 34, 806cbm of fuel including 5, 486cbm of aviation fuel for use by Royal Australian Navy helicopters. It had transfer fuel points for fuel, water and stores all with associated equipment and connections.
Ex-HMAS Sirius was docked at the WA Government owned Australian Marine Complex in Henderson, Western Australia. Decomissioned in December 2021, after more than 15 years of dedicated service providing fuel and stores to ships at sea.
