Swedish marina now protected from waves & wakes

After many years of deliberation, Gothenburg, Sweden-based marina owner-operator Grefab decided it would replace the wooden palisade surrounding Hinsholmen Marina. When the municipality-owned company had a geotechnical survey completed and learned that traditional bottom-founded construction wasn’t feasible, it turned to SF Marina. The leader in commercial and recreational dock solutions installed a state-of-the-art floating concrete breakwater that will last for generations to come.

While not directly on Øresund Sound, Hinsholmen Marina is still exposed to wind-driven waves and heavy wakes from passing high-speed ferries. Without protection, its fixed 1,550-slip wooden dock array would suffer damage and require constant repair.

SF Marina floating concrete breakwaters are engineered to overcome extreme weather events. Steel-reinforced with an exceptional buoyancy rating that makes them virtually unsinkable, the wave-attenuating pontoons are extremely stable.

The L-shaped 230m x 5m breakwater is comprised of 12 pontoons, each secured with two internal 61cm steel piles. Designed to adapt to future expansion at Hinsholmen Marina, they include integrated utility ducts for power and water.
