Sullivan Flotation Systems said it completed a marina project for the New York State Park System at Big Six Mile Creek, which is on an inlet of the upper Niagara River.
In recent years Sullivan also has completed marina projects on the Buffalo River, at the First Buffalo Marine Harbor for the New York Power Authority and at Mills Norrie State Park on the Hudson River.
“This was a rather unique project because the new dock systems were designed to withstand ice pressure and ice movement so they could remain in the water year-round,” John Bordner, of Allen Marine Services, a division of Hohl Industrial Services that oversaw the construction of the Big Six Mile Creek project, said in a statement.
Sullivan’s design team worked with the state’s designer and the general contractor to create a special mooring system that included SeaFlex mooring cables on a pulley system that allowed the new docks to flex with any ice pressure.
The marina’s anchoring system also required custom anchor brackets and a series of helical bottom anchors and elastic rodes to facilitate the fluctuating water depths and winter ice common to this area.
