Swiss security engineering developer Geobrugg AG has introduced fixed and floating waterside barriers to protect oil and LNG terminals, ships, nuclear facilities, dams, bridge piers and other sensitive waterside infrastructure from intruders and terrorist attacks.
The barriers come in two types: Fixed Security Barriers (FSB) and Floating Port Security Barriers (PSB). The systems are designed to protect against high-speed, low-tonnage vessels and low-speed, high-tonnage vessels loaded with explosives, according to the manufacturer.
Fixed Security Barrier
The Fixed Security Barrier (FSB) can be attached to existing structures or driven piles. High-tensile SATURN nets from Geobrugg are fixed to the piles without the need for floating construction. The manufacturer says the system can span widths of up to 60m, sustain large tidal differences, and resist wind, currents and corrosion from seawater. Geobrugg says the barriers have been used in the Persian Gulf since 2005.
Floating Port Security Barrier
The new Geobrugg FOXX Floating Port Security Barrier (PSB) consists of independent floating modules, 50m in length, equipped with high-tensile MAXX nets with a height of 2.5m. The barrier can be assembled on shore and moved into the water.
The floating modules are connected to protect a defined area from waterside boat attacks; they are designed to allow the barrier to absorb large tidal differences, heavy winds and waves. The high-tensile stainless steel wire is corrosion and UV resistant, the company says.
Under the supervision of the Polish Naval Academy, the barrier passed 1:1 live crash tests with multiple hits, according to the manufacturer.
Geobrugg AG, a division of the Brugg Group, develops and produces netting, mesh and ropes made from high-tensile steel wire for protection systems.
