Cyclone plan for wharves and moorings
How to secure vessels in Frances Bay Mooring Basin
During the cyclone warning stage, the Wharf Supervisor will inspect each vessel's moorings in the Frances Bay Mooring Basin.
Masters must remain aboard their vessels until the moorings have been inspected and the Wharf Supervisor or his representative is satisfied the vessel can be left unmanned.
The following mooring patterns should be used for vessels in the mooring basin, depending on expected wind speed, berth size and proximity of other vessels.
In normal conditions
Normals conditions means a maximum wind speed of 36m/sec or 70 knots.
For this wind condition a three line mooring pattern as shown below may be adopted.
In storm/cyclonic conditions
When the wind speed exceeds 36m/sec or 70 knots, the mooring arrangement of the vessels must be changed to not less than a four line mooring system as shown below. The arrangement varies depending on how many neighbouring vessels or empty berths there are.
|When the mooring basin is full||When there is one empty neighbouring berth|
|When there are two empty berths||When there are three or more empty berths|
