Maritime Structures

The proposed works include upgrades to the services to both existing wharves, strengthening of one wharf and extension of the other wharf. Dredging of the Coonawarra Basin is also required to cater for the increased draught of the new Arafura Class Patrol Vessels. Refer to Figure 10 for an artist’s impression of the maritime structures.

Office Accommodation

A new office building will be constructed within close proximity to the existing wharves. This facility will support the Arafura Class Offshore Patrol Vessel sea operations and also support the vessels and their crews when the vessels are docked at HMAS Coonawarra. Refer to Figure 11 for an artist impression of this building.

The proposed works also includes construction of new maintenance and logistics facilities and storage facilities for equipment and small boats.
