Abstract: A flow-diverter apparatus includes two hull and foil assemblies pivotally connected by rigid members and attached to control lines. Several flow-diverter apparatus may be joined by lines, cables or rigid links to form a flow-diverter system. The apparatus may also include lines/cables to vertically distribute control line force. Attachment points or lines for booms, scientific equipment, dispersion equipment, fire suppression equipment or other devices may also be provided. Apparatus may use horizontal hydrodynamic lift forces to create a diversion flow transverse to an onset flow, to deploy and hold equipment transverse to an onset flow, and/or to provide mixing on the surface of a body of water. Apparatus may be deployed from shore, from a fixed point in the water, or by a vessel.

Abstract: A laminated ice suppression mat which prevents ice from forming adjacent to objects partially submerged in a body of water subject to natural icing conditions has a laminate of buoyant, thermal insulating material intimately joined to a larger laminate of a reinforcing material. A fringe of reinforcing material may become embedded in an ice sheet which forms around the mat and causes the mat to move upward and downward about the object as the ice sheet rises and falls with the changes in water level.
