Vigilant is a similar work vessel to Invictus, with a slightly smaller length of 7.96m. Her deck capacity is also smaller at one tonne, with a one tonne hiab. With a remote ramp door, Vigilant works on many of the Brisbane River civil projects. Her smaller profile means she is even better equipped at accessing tight spaces, especially under ferry terminals, wharfs and jetties.
Vigilant has been moved by road to work on other key interstate marine civil projects such as the Eden Breakwater Upgrade Project in Eden, NSW and the Mayfield Berth Upgrade in Newcastle, NSW.
