SUPERYACHT FACILITIES Mooring superyachts in Bermuda Further to hosting events during the America’s Cup races in Bermuda in April this year, Caroline Bay Marina has now moved into its second phase of life as a much-needed permanent mooring facility. The upscale marina, on the Morgan’s Point Peninsula, was built by Marinetek North America as the hub of a luxury community that will be anchored by a Ritz-Carlton Reserve Resort. Caroline Bay Marina offers 2,340ft (713m) of dockage, making it not only the largest marina in Bermuda but also a centre for superyacht berths. Working to fulfil a contract awarded in June 2016, Marinetek provided and installed a multi-element dock system at a difficult location to meet appropriate hurricane loading regulations and adequately protect the marina basin from south-easterly waves. Marinetek liaised with project engineer Edgewater Resources of Michigan, USA and Bermuda-based marine construction sub-contractor Correia Construction. Marina Electrical Equipment supplied the electrical system, which includes three-phase power for megayachts, and EMP provided an in-slip pump-out arrangement. Mooring is available at heavy-duty concrete breakwater piers and at a protected aluminium dock arrangement. The 17ft (5m) wide dual-keeled floating concrete breakwater system was built using BRK5300 modules, each The newly completed Caroline Bay Marina (above) is now filling up with boats (right) after the excitement of the America’s Cup. weighing 52.4 tons and measuring 17ft (5m) wide x 65ft (20m) long x 6ft (2m) high. These are anchored by 80ft (24m) long steel pipe piles of 30in (76cm) diameter and have internal stainless steel pile guides with rollers. Marinetek used its 220 Series aluminium framed system to create 12ft (3.6m) wide main docks and tee-end docks with ipe decking and concrete floats. Tapered finger piers with varying lengths of 35, 40 and 45ft (11, 12 and 14m), have polyethylene floats and ipe decking and can be adjusted in position – along with corresponding cleats – using a track-mounting system that runs along the main dock. The aluminium docks are anchored using 60ft long steel pipe piles of 14in (35cm) diameter and have internal aluminium pile guides with rollers. The combined arrangement gives 88 slips for boats up to 80ft (24m), 33 slips for megayachts and additional Med style mooring for megayachts. Dockage on the lee side of the breakwater provides space for vessels up to 300ft (91m) long. Working in Bermuda was a challenge in itself. “The environment is very corrosive with heavy salt content in the water and the air, and the location is remote,” explained Marinetek North America general manager Bob Berry. “All docks and equipment were shipped to the island as local supplies and tools are scarce and very expensive.” To help combat the corrosion, Marinetek galvanised the upper half of the steel piles and used stainless steel for the pile guide frames. Pile installation was, however, difficult. “Below an upper layer of sand we encountered very dense rock,” Berry continued. “We couldn’t drive the piles through the rock and special equipment had to be brought in to do this.” With the finishing touches completed to schedule, Caroline Bay Marina took pride of place as an America’s Cup Destination. It continues as a valuable marina asset for the island of Bermuda and its idyllic setting will take further shape when the first phase of the Ritz- Carlton Reserve Resort completes in early 2019. - November/December 2017 37
