 Advice:  Dredging and Beach Nourishment Works - Chelydra Beach North Coogee

Mariners are advised that dredging works at Chelydra Beach (north of the Port Coogee marina) will commence in early June 2022 and will proceed until approximately mid July 2022.

Dredging will mainly occur Monday to Saturday between the hours of 0700 and 1800hrs.

The works are being carried out by the 18m cutter suction dredge Mudlark I, equipped with a floating pipeline that runs directly behind the dredge and which will be marked by yellow buoys with flashing yellow lights. The floating pipeline transitions to a submerged pipeline which will run along the seabed and cross the Port Coogee entrance channel.

The dredge has no self-propulsion and uses anchors and spuds to move. The dredge and connected pipeline will remain in the area of operation after normal operating hours for the duration of the works.

The dredged sand will be used for renourishment. There are two sites that will be utilised.

For the first half of the dredging works:

Material will be discharged at the southern disposal site at South Coogee Beach
The submerged pipeline extends from the dredge area to the breakwater on the southern side of the Port Coogee marina entrance channel
From this point, permanent land-based pipeline will be utilised

For the second half of the dredging works:

Material will be discharged to the northern disposal site, just south of the Catherine Point groyne
The submerged pipeline extends from the dredge area to the northern end of Chelydra Beach
From this point, temporary land-based pipeline will be utilised

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

Before navigating past Mudlark I during operating hours, mariners are requested to contact the operators who will be monitoring the following radio frequencies:
VHF Channel 16
27MHz Channel 91

Mariners are advised to use caution when navigating in the area and keep well clear of the above operations.

LIDAR buoy location 2: 31° 52.594'S, 115° 43.121'E

LIDAR buoys are circular buoys with side mounted solar panels and wind generators extended on top. They are yellow and black in colour, approximately 4.5m in diameter and 4m in height, and equipped with flashing yellow light.

Flash rate: Q(5) Y 20s

LIDAR buoys will be deployed periodically at the above locations until around 23 December 2022.

A wave rider buoy has been deployed at the following location:

Wave rider buoy: 31° 52.532'S, 115° 43.318E

 Advice:  Breakwater construction works, Ocean Reef Marina

Mariners are advised that works to construct two new breakwater groynes at Ocean Reef Marina are due to commence in mid April 2021 and are expected to be completed around February 2023.

Works will take place Monday to Saturday, between 7am to 6pm as required, using land based heavy machinery, including long reach excavators (approximately 30m reach) positioned on the breakwaters.

The two areas at the end of each new breakwater will be marked by a Green lit Starboard Buoy at the end of the southern breakwater and a Red lit Port Buoy at the end of the northern breakwater.

Access to the marinas boat ramp and jetties will be maintained at all times.

Land based operators will monitor Marine Radio VHF Channel 16 during operating hours.

Acting pursuant to the powers conferred by Section 66 of the Western Australian Marine Act 1982, I hereby close the following area of water to all vessels during the above works period:

 Advice:  High level bridge repairs, The Navy Causeway Mangles Bay Rockingham

Mariners are advised that maintenance works are scheduled to commence on the High-Level Bridge at the Navy Causeway, off Point Peron Road, Mangles Bay Rockingham, in late September 2021.

These works will take place Monday to Saturday during daylight hours and are expected to be completed around 31 March 2023.

A floating work platform (6m x 12m) and scaffolding will be used in stages for all works and will be lit by yellow flashing lights. The floating platform will be lifted to perform works to the underside of the bridge. Where the platform is lifted this will reduce clearance to the bridge deck by approximately 3.5m and will also reduce the width of the span by approximately 6m in the location of the work platform. Scaffolding will also be installed on the piers and this will reduce the width of the span by approximately 2m near the bridge deck level to provide access to the scaffold.

The floating platform will be erected in the navigation span from Monday 4 July 2022 to Monday 5 September 2022

Access to the navigation channel will be maintained at all times during these works.

Operators will monitor Marine VHF Channel 16 during operating hours.

Mariners are advised to navigate with caution when transiting the area and stay well clear of the above works at all times.
