Engineering and quality scrutiny required unique features including ⌀500mm cast stainless steel rope drums, ⌀28mm 7 x 37 G316 stainless steel cables and a worm gear box with winch design output torque of 90,000Nm of torque and 461 kN lifting capacity (46tn.)

• 3340mm wide x 4402mm high marine grade aluminium segmented roller stoplogs (in three 1500mm segments) including embedded stainless steel frames, certified stoplog lifting frame and stoplog storage rack. • Stainless steel sidewinder gates with electric actuators. 300mm wide, up to 4m high.

• 1580mm wide x 2020mm high marine grade aluminium stopboard in a stainless steel frame.

• 2000mm wide x 2209mm high undershot gates.
