New marina for Swedish archipelago

Sweden’s Värmdö Municipality is building a new marina at Stavsnäs Vinterhamn to accommodate the growing demand for berths in the Swedish archipelago.

Phase One of construction has already started, with an SF Marina floating concrete breakwater and walkway transforming the setting into a hub of yachting activity.

A 70-metre (229-foot) breakwater has been installed using SF Marina SFBW 400 floating pontoons. These wave attenuators are made from double-reinforced concrete, making them virtually unsinkable. Each section is connected with an energy-absorbing coupling system that distributes stress during heavy wave action.

SF Marina’s SF 1030 concrete pontoons were chosen for the 120-metre (393-foot) dock walkway. Extremely stable due to their low centre of gravity, the sections feature a modest 0.5-metre (1.6-foot) freeboard.

WM-Bommen fingers from 6 to 10 metres (19 to 32 feet) long accommodate a wide range of boats at the 70-slip facility. The main walkway has integrated ducts that feed the El-Björn power pedestals; slips also feature freshwater hook-ups and free Wi-Fi.

The breakwater and walkway were built at SF Marina’s Wallhamn, Sweden facility and transported to the site by barge. Because of their modular design, installation is said to be faster than traditional wooden or poured concrete structures.

Stavsnäs Vinterhamn is an important public and freight transportation hub between the Swedish mainland and the archipelago islands. The new recreational marina features a pump-out, harbour office, store, repair centre, shower facilities and increased parking area with residential housing planned.

Phase Two of the marina project will begin in spring 2022.
