SF Marina has installed its largest floating concrete breakwater using its
massive SFBW1000 pontoons. The milestone structure protects Kajen, a
new condominium complex in Skärhamn, Sweden.
Each SFBW1000 pontoon is 20m L x 8m W x 3m D with a 0.8m freeboard.
The Kajen project uses six in an L-shape that extends 80m, linked
together by four W5000 connectors. Electrical and water supply services
are easily accessible through integrated conduits.
In combination with SF Marina’s patented coupling and advanced mooring
system, the SFBW1000 floating Concrete Breakwater is an excellent
wave attenuator with superb stability. While somewhat protected from
the Skagerrak strait by a series of offshore islands, Skärhamn still sees
heavy storms, especially in winter. Engineered to absorb extreme storm
loads, the breakwater at Kajen has a breaking load of 260mt per joint.
Remarkable buoyancy of the SFBW1000 pontoons is due to the unique
reinforced concrete and Styrofoam construction—they’re virtually unsinkable.
Manufactured in accordance with Eurocode SS-EN1992-1-1, the
structures are easily shipped from the factory to anywhere in the world.
Located 66km northwest of Gothenburg, all Kajen condominiums boast
stunning views of mountains, harbor or open sea. The structures use materials
and colors that pay homage to the rich heritage of Sweden’s west
coast traditional buildings. Scheduled to open this spring, its website is
