Working government and municipal docks see heavy use with the more- than-occasional hard hit from vessels. When the police department of Gdańsk, Poland, needed to rebuild its 144m section of Marina Sienna Grobla, it chose the proven durability and reliability of SF Marina.
The RFP demanded quality parameters of the highest level. SF Marina responded with twelve 12m L x 2.4m W SF1024 floating concrete pontoons. Basalt reinforcement was chosen because it’s stronger than steel and has a higher tensile strength. Their sheer weight and low center of gravity make them extremely stable, even with the frequent heavy wake action along the Motława River. Unsinkable, the pontoons deliver the exceptional durability needed for years of heavy use. SF Marina was so confident in their product’s ability to withstand natural and human-generated abuse, it provided the project with a seven-year warranty.
Available in widths from 2.4m to 8m and lengths from 10m to 25m, SF1000-Series floating concrete pontoons from SF Marina feature stainless steel fittings, extra-strong coupling wells and finger-jointed fenders. The versatility of the design provides the ability to construct virtually unlimited configurations making it the ideal solution for working docks.
SF1024 floating concrete pontoons have integrated electrical conduits and water pipes for low maintenance and tamper resistance. The Gdansk project included IP67-rated power pedestals from Seijsener techniek with a heightened current security class.
Because of the semi-modular design of an SF Marina floating structure, the entire Gdańsk dock was transported by truck, although it could have also been shipped via barge. It was built 900km away in the company’s Wallhamn, Sweden, manufacturing plant. This range of logistical solutions enables even the most remote locations to benefit from the established quality of SF Marina products.
