RIVIERA BEACH, FLORIDA, USA
The City of Riviera Beach in Palm Beach County, Florida, contracted Marinetek North America (NA) to supplyhigh specification floating pontoons and breakwaters as part of a major redesign and upgrade of the City Marina.The project is the result of many years of studies, proposals and plans, and is aimed at revitalising the marina district and city waterfront.
Situated in a prime deep-water location on the Palm Beach Inlet of the Intracoastal Waterway, the marina had oldfixed docks and utilities that were in need of replacement.
Plans were extensive and demands high, as City Marina manager Ed Legue points out: “The 110-slip marina has been completely redesigned and will incorporate new 14ft wide floating concrete breakwaters and floating concrete docks to incorporate community day docks, water taxi docks and 21 boat lifts.”
“Utilities will include 30A, 50A and 100A power, in-slip pump-out, Wi-Fi, underwater lighting and high-speed fuelling. Transient dockage will be available for vessels up to 300 feet,” he continues.
A total of $25-40 million will also be spent on upland development that includes a boardwalk, car parking, retail stores, restaurant, housing, industrial/office space and redevelopment of the main feeder road US Hwy-1. “The project will completely change the look and feel of the entire city,” Legue asserts.
Meeting strict specifications
The new Marinetek floating dock system must withstand a Category 3 hurricane (sustained winds of 110 mph) with associated storm surge, wind and waves while fully loaded (100% occupied) and must survive the forces of a Category 4 hurricane (sustained winds of 155 mph) while unoccupied. The system not only meets but actually exceeds these specifications and Marinetek has issued a 10-year warranty for the performance of the dock systems in these conditions.
In addition to superior strength and ability to withstand rough water, Marinetek’s pontoon connection design also met precise criteria. City engineers would not accept an arrangement that incorporated an external waler or similar and demanded that connection components be flexible and designed for ‘minimum to no maintenance’ over the life expectancy of the docks.Marinetek’s system includes 14ft wide x 65ft long concrete modules of Super Yacht type, which are connected using a simple flexible bolt/rubber block design. This is a proven method that requires virtually no maintenance and provides an extremely stable dock that can flex as required. The breakwater modules, of type BRK with keels, meet strict wave attenuation and performance specifications.
All pontoons and breakwaters for City Marina are being built in the USA by Marinetek’s Mobile Production Team, an expert taskforce that can fabricate docks anywhere in the world. Due to the large size of the floats, the mobile team is manufacturing all units at a yard adjacent to the marina. “This completely eliminates shipping of the floats, which greatly reduces costs and delivery time. It also allows City engineers to easily monitor construction quality,” says Marinetek NA managing director, Kent Johansson. “Once adequately cured, the docks can be launched via travel lift and towed to the site.”
The grand opening of phase 1 will be held in late January and phase 2 is scheduled to complete in May this year.
