Melbourne records practical completion of its 63-beacon replacement programme in March 2026. Its staged renewal plan coupled pile installation to the transfer of each beacon's navigation function.

The owner records completion after a two-stage programme

Port of Melbourne's completion record states that 63 monopile beacons were replaced, beginning in September 2024 and reaching practical completion in March 2026. The July 2025 factsheet divided the work into 29 first-stage and 34 second-stage piles, with 50 m clearance and minimum wake and wash around active work. Its planned second-stage window extended into 2027-28; the later owner record reports completion [1-2].

Pile installation and navigation release need the same location reference

A beacon replacement changes a physical structure that vessels use as a navigation reference. The construction sequence therefore needs a defined status for the old beacon, any temporary marking and the replacement before the next vessel movement. Surveyed position, elevation and the installed light or daymark should be checked against the approved asset requirement. The method should also state when the work vessel and equipment can leave the area and who releases the replacement navigation aid into service. Otherwise, mechanical completion and the harbour's operational information can describe different states of the same location.

Evidence conclusion

Use the July plan as construction context

The port's May 2025 tariff statement recorded Stage 2 long-lead procurement already under way while the first stage was still being delivered [3, p.21]. Overlapping procurement and installation lets the spread move between workfronts as components become available. The next location needs its replacement pile, top structure and navigation equipment ready for that move. The July factsheet provided for notices as works moved between areas [2]. Standardise the installation and acceptance record, then retain site-specific checks for current, depth, ground and traffic.

Outstanding evidence

  • Position, light or daymark and asset acceptance records
  • Construction-to-navigation release for each beacon
  • Current Ports Victoria notices for present-day navigation
