HMAS Sydney Mast Refurbishment
Description:
The HMAS Sydney Mast at Bradley's Head is a heritage mast taken from HMAS Penguin which sunk off the coast of Western Australia in the early 1900s. It was restored and placed at Bradley's Head, Mosman in 1965 and is of great significance to the HMAS Sydney Association as well as the Royal Australian Navy.
Due to the extensive corrosion, deterioration and failure of the existing protective coating, it was deemed necessary that remediation works were required in order to further preserve and prolong the life of the mast.
Key Aspects:
Erection of scaffold access and encapsulation.
Blasting & painting of the entire mast structure.
Structural steel strengthening to the mast structure consisting of installation of compensating plates, steel angles / bracing.
Removal and refurbishment of the top mast offsite and provision of new yardarm prior to re-instatement onsite.
Provision of 13 new stainless steel flat and curved window frames
Provision of a new handrail and glass balustrade to the elevated viewing platform of the HMAS Sydney Mast.
Provision and installation of new rigging rope and equipment utilised for the raising of a larger Australian flag (5 breadth).
Working on a cliff edge on Sydney Harbour posed many safety and environmental challenges with winds picking up in that area and ensuring containment of all the grit during blasting of the steel mast.
Further allowances were made for the number of heritage monuments within that area, and the National Park itself.
