Specialized Structures and Floating Foundations

“SF Marina Systems USA constructed the Eco Doc system located in the beautiful, yet rough, waters of New York Harbor. The heavy duty dock allows the residents of Bay Ridge, Brooklyn too long cut off from the water that surrounds them, to once again get from the bay to the ridge, and the ridge to the bay, thanks to the robust SF system.”

- Rowland Lewis, President | Metropolitan Waterfront Alliance - Bay Ridge, Brooklyn, New York

Eco Dock Project

Metropolitan Waterfront Alliance

  • Bay Ridge, Brooklyn, NY
  • 2014
  • 40' x 34' multi-freeboard

The system combines a 1240 with a 10” freeboard for kayaks and two type 2430 custom sections with a freeboard of 54” for the large vessels.Utilizing a stainless steel post tensioning system, all the units join to form one solid structure.

The Metropolitan Waterfront Alliance had a great idea; Create a multi-use dock which would welcome the community of Bay Ridge in Brooklyn to water, and provide access to all sizes of vessels. The Community “Eco Dock” did just that. School children have access to educational boat trips, learning science and new experiences. The project location was a challenge due to fast currents, large wind driven waves and regular ferry wakes; never ending movement of the dock system. The system will stand on its own for many years of uninterrupted service.

1500 Post Tensioned Foundation Project

Salt and Still Hotel

  • Tjorn, Sweden
  • 2008
  • 40' x 160’ floating foundation

Eight SF type 1550s were post tensioned together to form the large foundation on which the hotel was built.

Salt & Sill is an island inn that opened in 1999 to accompany and international cuisine restaurant based on local raw materials and strong influences from the coast. Lacking the land to build the Inn, SF Marina Systems offered a solution. In the autumn of 2008, Sweden’s first floating hotel opened alongside the restaurant. The hotel is a meeting and conference venue with 46 beds, and open all year round.

Salt & Sill has been awarded the status ""Worth a Journey"" and ""White’s Heart"" by White Guide, the Swedish Restaurant Guide. It was also awarded a quality accreditation ‘Västsvensk Mersmak’ by the Tourist Board for the West of Sweden.

1200 Floating Bridge Project

Colonna's Shipyard Floating Bridge

  • Norfolk, Virginia
  • 2014
  • 16' X 291' floating bridge

16’ wide x 291’ Type 1250- 26.5m (16x87’ single cast sections) 1250 -10m, with cable connectors, and custom hinged swing bridge section.

Colonna's Shipyard in Norfolk, VA is an industry leading shipyard and repair facility. The company has an expansive shipyard campus with large canal docking areas. The employees of the shipyard had to walk long distances around the canal areas to get from one side of the yard to the other. A permanent fixed bridge was not practical, and would block the canal from vessel movement. The solution was a solid cast concrete floating bridge, with a “swing section” to allow vessels to pass thru. The wide floating bridge was fitted multiple ramps for two way traffic, lights and railings to accommodate foot traffic , and small vehicle traffic. To accommodate vessels the systems also has HD D-Fender and bollards.
