Abstract
In one embodiment, dispersants are injected directly into a plume of oil in a subsea environment. The dispersant is supplied from a vessel, through a tubular string and flows through a routing manifold into a flexible hose. The hose then transports the dispersant to a distribution manifold, which is disposed on the sea floor, and permits injection of dispersants at multiple locations at the same time around the leaking oil. Injection of dispersants from the distribution manifold may be through injection wands, or the dispersant may be transferred to a containment or collection device located above the plume of oil, wherein nozzles are disposed around the circumference of such containment or collection device. If the dispersants are injected into the leaking oil through injection wands, such wands may be held and/or manipulated by an ROV.
