Vikoma Cascade Skimmer

The Cascade Skimmer is an adjustable weir skimmer designed to be particularly effective in large oil spills where a high oil recovery rate is required.

The system is supplied with the Cascade head, GP60/4 power pack and control console. It is capable of handling a wide range of oil viscosities. It has a floating circular weir device with an onboard, hydraulically driven, positive displacement VikoPump. The weir lies just below the oil surface and the top layer of the oil flows over the weir lip and is pumped away to storage. A remote control console allows the operator to optimise skimmer recovery by varying the pump speed and hydraulically adjusting the depth of the weir relative to the oil thickness.

Key features and benefits:

  • The fluid recovery rate of the Vikoma Cascade is 183m3/hr
  • The VikoPump is particularly adept at handling highly viscous fluids and solids of up to 30mm diameter; it has been proven to be highly efficient in aggressive environments and capable of long maintenance-free operation and dry running for protracted periods
  • The Cascade’s arms are hinged and can be folded for transport or containerisation
  • Two Cascade skimmers meet a Tier 1 response requirement under OPA ’90
  • The unique discharge outlet and hose float assembly, which reduces hose drag and ensures stability, means that the Cascade can operate very effectively from a vessel in a towed array at speeds of up to 2 knots
  • The discharge hose has a 6 inch nominal bore which allows for the easy discharge of higher viscosity oils.
