Excerpt from Siemens publication "Building Up"

The port of Los Nagels now has the capability to respond to heightened threat levels through the deployment of a floating-security barrier designed by SBT (Siemens Building Technologies)

pkr. Under the watchword of "homeland security", efforts to strenghten internal and external national security are continually being stepped up. Greater attention is being paid to the security of ports, particularly in the USA itself, with special spotlight on the major international US container ports of Los Angeles and Long Beach in Southern California. (Siemens) Building Technologies was awarded a 2.9 million dollar contract to design approximately 30000 meter of floating security barrier for these two key ports. In the event of a security alert the floating barrier can be rapidly deployed to prevent smaller unauthorized vessels from entering the inner harbor or getting close to high-risk targets. The security barriers constructed from steel cables and floating plastic modules each 7.5 meters long, are build to withstand the most adverse weather conditions. The barriers are fabricated by Wave Dispersion Technologies. In collaboration with the manufacturer, SBT has succeeded in providing a new custom-build design within the given budget constraints.
