Mid West notices

Mariners are advised that works to install a new Pen set C in the Batavia Coast Marina are scheduled to take place from Monday 04 November to early May 2025. The Marina will be installed in two parts. At the beginning of the construction period several steel piles will be driven and left unattended. Toward the end of the time frame the floating marina pontoons will be installed and the services installation completed.

The works, including piling operations, will be conducted Monday to Friday between 7am and 5pm. Other activities than piling may be conducted on Saturday between 7am and 5pm.

The works are conducted using piling jack up barge ‘SMC3’ (16.2m x 6.97m), a pipe handling barge (12m x 2.4m), a workboat and land based equipment as required.

The works area will be delineated by yellow exclusion buoys, approximately one metre in height and equipped with flashing yellow lights. All piles will be marked with reflective tape and located within the confines of the works area.

Flash rate: Fl Y 2.5s

There may be an impact for vessels leaving the southern berths at Pen set B or the vessels moored along the boardwalk. However, fairways and access to all existing jetties and the boat ramp within the marina will be maintained at all times.

The work barge will be moving within the marina every 2-3 days, mariners are advised to keep a safe distance from the barge and stay clear of all exclusion markers.

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 Channel16 during operating hours.

For further information regarding these works please contact SMC Marine Superintendent Jeff Offer on 0423 117 023.
