Conditions slightly improved, challenges remain

09 Mar 2022 / Brisbane River, Australia

Maritime Safety Queensland (MSQ) has reviewed operational limitations on the Brisbane River based on slightly improved conditions and available information about navigation hazards such debris, shoaling, etc.

Brisbane River currents have remained fairly consistent as dam releases continue. Ongoing assessment of port channels, aids to navigation and critical infrastructure continue as conditions allow.

Wivenhoe Dam will continue releases through today (9 March) with affects expected to be seen downstream at the port tomorrow. Debris is present as navigation hazards but floating debris has reduced. Overall, conditions continue to be challenging but improving. This will allow the transition from response to recovery in the coming days.

Arrivals and departures continue on a case-by-case basis, with further movements scheduled. A part of these movements includes selecting certain vessel/manoeuvre types to gain further knowledge in the changing river conditions.

Based on the current conditions, information gained from these trial manoeuvres and the significant ongoing hydrographic survey effort, the following update to Fisherman Island operational limitations for Wednesday 9 March have been developed:
- 24/7 operations
- Channel depth of 12.4m with UKC managed utilising SUKC values for all drafts 11.0m and above
- 1 tug escort from/to Coffee Pots – Only for vessels that have been alongside before 2 March
- 2 tugs for all movements, no bow/stern thruster replacement
- Additional tugs as per ongoing pilotage assessment
- Quay line separation to be 50m and remain in place at all times
- General draft restriction of 11.5m when berthing head-up or head-down
- LOA less than 300m

A trial departure above Pelican Banks scheduled yesterday did not go ahead as conditions were not suitable. It is expected to take place today. Pending results of these trials and based on survey information operations in the river will commence however there is likely to be operational limitations associated with current direction, daylight, LOA and draft limitations. These will be advised to all parties once developed.

VTS will coordinate with agents on vessel scheduling for those that meet the above criteria for further potential limited movements. No bookings to be made without VTS coordination.
