  Notice 2018-54: South Yunderup channel dredging

South Yunderup channel

Mariners are advised that maintenance dredging works in the South Yunderup Navigational Channel are scheduled to commence around Tuesday 3 April 2018 and are expected to be completed by Wednesday 31 October 2018. Dredging will occur Monday to Friday between the hours of 0700 and 1800 hours and Saturdays between the hours of 0700 and 1400 hours.

The works are being carried out by the cutter suction dredge 'Swan V'. The dredge has no self-propulsion and uses anchors and spuds to move. A 50 metre floating pipeline is connected to the stern of the dredge. The floating pipeline is generally marked by light poles equipped with rhythmic yellow lights operating at night. For the duration of the works the dredge and pipeline will remain in the area of operation after normal operating hours unless the dredge is moved for shelter from unfavourable conditions.

A semi submerged and floating pipeline, marked at various intervals with white floats, will deliver the dredged material to the discharge sites to the south and north of the channel. The discharge sites will be marked with yellow marker buoys approximately 1 metre in height, equipped with flashing yellow lights.

The dredge will be operating from side to side whilst in the channel. The operators cannot always see approaching vessels therefore allowance for the movement of the dredge should be made by mariners. Mariners should take all due care and maintain slow speeds in the area.

When traversing the area mariners are requested to contact the dredge operators who will be monitoring the following radio frequencies.

  • VHF Channel 73 or Marine 27 MHz Channel 90.

The dredge will exhibit shapes and lights in accordance with the Prevention of Collision at Sea Regulations 1983.

Mariners are advised to use caution when transiting the area and to remain well clear of the above operations.

  Notice 2011-98: Commercial fisheries, Mandurah to Geraldton

Commercial fisheries

Mariners are advised that commercial fisheries for rock lobster and octopus are established in Western Australian coastal waters, along the coast from Bunbury to the Pilbara and from shore to the 200 metre isobath with areas of high activity between Mandurah and Geraldton, particularly in the region Cervantes to Dongara.

Fishing is done using pots or traps sitting on the seabed. Each fishery contains in excess of 30,000 pots which are marked by floats not less than 200 mm in diameter and coloured, usually fluorescent green.

The floats are located on either end of a line of pots or on each individual trap. As the floats are small and unlit, a good lookout is essential when transiting the region. The fishery is active throughout the year with operations conducted by licensed support vessels. Operators monitor Marine VHF Radio frequencies 74 and 78.

Mariners are advised to navigate with caution when navigating in WA coastal waters to keep well clear of all fishing operations at all times.
