Patent ID: 8784004

Claim:
A system for supplying a chemical dispersant to a subsea hydrocarbon discharge site, comprising: a dispersant source and a dispersant pump configured to pump dispersant from the dispersant source; a first flow line coupled to the pump; a subsea dispersant distribution system coupled to the first flow line; a dispersant injection device coupled to the distribution system and configured to inject dispersant from the dispersant source into a subsea hydrocarbon stream; wherein the dispersant source comprises a dispersant storage tank disposed on a surface vessel; wherein the first flow line extends subsea from the vessel to the dispersant distribution system; and wherein the subsea dispersant distribution system comprises: a subsea distribution panel hung from a lower end of the first flow line, wherein the distribution panel includes an inlet and a plurality of outlets; a subsea manifold positioned at the sea floor, wherein the manifold includes a plurality of inlets and a plurality of outlets; at least one flow line extending from the distribution panel to the manifold; and a flow line extending from the manifold to the injection device.
