Fixed Barrier

FSB Barrier System

• Ultimate stopping energy 3.7M ft lbf/5.01 MJ
• Working stopping energy 1.25M ft lbf/1.69 MJ

Constructed System

• Piling length determined by seafloor conditions, net height requirements and water depth to maximum of 80 ft (12.38 m).
• Example: A 60 ft (18.29 m) deep system would require 102 foot-long (31.09 m) pilings as follows depending, of course, on site conditions.
  • Embed in seafloor – 30 ft (9.14 m)
  • Seafloor to surface – 60 ft (18.29 m)
  • Extension above surface – 12 ft (3.66 m)
• Pilings are generally spaced no more than 100 ft (30.48 m) apart.
• Net depth and elevation designed according to risk assessment of site conditions, water depth and above water stopping requirements generally beginning at a height of 8 ft (2.44 m).
• Galvanized or stainless steel mesh nets above water and generally in the intertidal zone.
• Subject to design, there is no practical limit to the amount of energy the system can withstand under varying wind and current conditions.
• Pilings and shore connection systems sized for maximum strength.
• Extensively tested.

Performance

• Low maintenance – Corrosion resistance proven over nearly 10 yrs. of “real-world” operations.
• Attack resistance – Best resistance to high-energy boat impacts at 3.7M ft lbf/5.01 MJ.
• Sustainability – Ten-year proven resistance to marine environment permanent stress including weather, sea swells, sea waves, chaffing, marine fouling and sea life.

Expertise and Service

• Expert installation – teams include divers and marine constructors with over 30 years of experience working with each other.
• Fosters local partnerships – local sub-contractors join the team when qualified, gaining work skills and technology training.
• Life-cycle value – team experts provide life-cycle cost estimates to be used in formulating investment and insurance calculations and in selecting the system that meets the customer’s need.
