 Advice:  Dredging Works - Port Beach Sand Nourishment Project

Mariners are advised that Dredging and Rainbowing works at Port Beach are scheduled to commence on Monday 12 September 2022 and are expected to be completed in approximately one month.

Dredging will occur 24/7

The works will be carried out by the Trailing Suction Hopper Dredger ‘Modi R’ (67.05m x 12.80m).

The Dredge will be ‘Rainbowing’ the sand which is a method by which trailing suction hopper dredgers place material in shallow areas by pumping into the air through a hose with a nozzle.

‘Modi R’ will exhibit shapes and lights in accordance with the Prevention of collisions at Sea Regulations 1983.

Before navigating past ‘Modi R’, mariners are requested to contact the operators who will be monitoring the following radio frequencies:

 Advice:  Replacement of Navigational Aids Rottnest Island

Mariners are advised that works to replace eleven (11) Navigational Aids around Rottnest Island will be occurring from October 2022 to December 2022.

At times, these works may temporarily delay vessels transiting through the affected Channels, by work vessels positioned on the edge of navigable channels with minimal affect on navigability.

At times, Barges may be left moored and unmanned outside of channels overnight, remaining lit and appropriate shapes displayed. Any partially completed piles will be temporary lit if left incomplete overnight.

During non-working days, barges will be left at layby moorings in South Thompson Bay.

The works, Including Piling activities, general construction, demolition and diving, will be conducted from Monday to Saturday between 0700 and 1800 using commercial vessels, Reel Pressure, Y2K and King George. Coordinates of construction sites shown below.

All vessels taking part in these works will display shapes and lights in accordance with the Prevention of Collisions at Sea Regulations 1983 at all times.

Operators will monitor Marine VHF Channel 16 during operating hours.

Mariners are advised to exercise caution and strictly maintain a 5 Knot speed limit and no wash when transiting through Rocky, Geordie and Thomson Bays during this period.

Works on the reclamation areas will commence in September 2022 and are expected to be completed around June 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), front end loaders, dump trucks and dozers.

Construction works for the reclamation areas will be within a silt curtain located in an alignment from the northern end of the boat ramp to the head of the northern breakwater. The silt curtain will be marked by red flashing lights spaced at approximately 100m intervals.

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

Pursuant to section 66 of the Western Australian Marine Act 1982, I vary the previous notice relating to the closure of waters published on the Departments Temporary Notice to Mariners website on 26 March 2021 and close the waters to all vessels within 20m of construction works occurring on the Ocean Reef Marina Southern breakwater.

 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.
