Scuttling The Tobruk

Scuttling The ex-HMAS Tobruk

After 34 years of service, the ex-HMAS Tobruk was brought to Bundaberg to prepare for her scuttling to her final resting place in the Wide Bay waters between Bundaberg and Hervey Bay.

Ex-HMAS Tobruk is was moored at the Port of Bundaberg for the scuttling process in which she was fully prepared, sunk and opened as a dive site for experienced divers visiting the Southern Great Barrier Reef.

The process included:
* Removing all fuels, oils and greases
* Identifying and removing all hazardous materials, including polychlorinated Biphenyls (PCB's), asbestos, heavy metals, batteries, chemicals, plastics etc.
* Removing items that could break loose during the scuttling process or be a hazard to divers
* Preparing a safe and interesting dive site to suit different levels of expertise, including cutting diver access holes, removing items that could be a safety hazard (including cabling, non-structural partitions, hatches/doors) and sealing some areas to prevent access for safety reasons
* Designing the scuttling process to ensure the vessel would settle to the seabed with its structural integrity maintained, in an upright position in the correct location, depth and orientation
* Towing to the scuttling site, undertaking final on-site preparations, and scuttling the ship
* Post-scuttling activities, including retrieving debris, clearance dive, and repairing any damage from the scuttling process.

This process was estimated to cost between $6-7 million and expected to take 2 years to complete.
