Rubber Silt Curtains   Rubber Silt Curtain   The solid float type rubber silt curtain has good flexibility, high buoyancy, and good wave riding performance and stability. It can be placed at designated points and towed by tugboats to sweep oil, control, intercept, and guide oil spills at sea. It can also cooperate with oil harvesters to sweep and collect oil, prevent oil spills from spreading, reduce and eliminate oil pollution, also it can be applied for dredging project to protect the marine environment.   Specifications: Type WGJ600 WGJ800 WGJ900 WGJ1000 WGJ1100 Total Height 600 mm 800 mm 900 mm 1000mm 1100mm Free board 210mm 280mm 320mm 350 mm 390mm Draft 380mm 460mm 490mm 520 mm 610mm Unit length 20 m 20 m 20 m 20 m 20m Tensile resistance of fence tape 280 KN 320 KN 360 KN 400KN 440KN Allowable working tension 70 KN 70 KN 80 KN 100KN 100KN Working Temperature -30---+60℃ -30---+60℃ -30---+60℃ -30---+60℃ -30---+60℃ Storage Temperature -30---+70℃ -30---+70℃ -30---+70℃ -30---+70℃ -30---+70℃ Max Wave Height 1.5m 1.5m 1.5 m 2 m 2.0 m Max Wind Speed ≥10m/s ≥15m/s ≥15m/s ≥20m/s ≥25m/s Maximum flow rate ≥1.0 m/s ≥1.5 m/s ≥2.0m/s ≥2.5m/s ≥2.5 m/s Maximum linear drag speed 8 Kn 8 Kn 8 Kn 8 Kn 10 Kn Maximum arc-shaped drag speed 3 Kn 3 Kn 3 Kn 3 Kn 4 Kn Floating weight ratio 8：1 8：1 8：1 8：1 8：1 Installation and laying time of 200 meters ≤20min ≤20min ≤20min ≤20min ≤20min
