The superyacht industry is growing fast and Australia is seen as a potential; destination for vessels traditionally associated with the Caribbean or the Mediterranean, and superyacht hub in its own right. However, these supersized recreational vessels have unique infrastructure requirements that are not typically provided or even considered in Australian ports and marinas. This paper focuses on the design and construction challenges, and showcases achievements, of what is currently the largest superyacht berth in Australia, considered a game changer for the local industry. The berth consisting of a 163m long and 4.6m wide floating pontoon arrangement retrofitted into the Southport Yacht Club on the Gold Coast, has been engineered, designed and built to welcome and accommodate some of the world's largest recreational vessels. With significant existing site constraints to consider, the design and construct team of Royal HaskoningDHV (RHDHV), MGN Civil and Superior Jetties delivered an optimised alternative design to the proposed tender phase concept that met the Project requirements but improved the overall outcome significantly through: • improved marine biodiversity (by eliminating the need for vertical sheet piling); • working with nature (reducing environmental impacts and improving navigational safety); • accommodating existing infrastructure and overland flood flow paths; • significantly reducing the need to remove established mature trees on site (no deadman tie backs in the adjacent park); • adaptive design for consideration of climate change and sea level rise (innovative pile and pontoon design and adaptive revetment design); • reduced ongoing maintenance (no need for cathodic protection); • allowing large fuel trucks to get access adjacent to the berth, prioritising safe bunkering; • including 4.6m wide pontoon system allowing for vehicle access for safe loading of stores or maintenance of vessels; and • future proofing the facility to handle the growth in size and demand of superyachts, designing it for vessels of up to 160m.
