  • In situ oil cleanup and recovery using smart polymer integrated surface vessels
    Patent number: 11407657
    Abstract: Smart membranes (14) are integrated into a small, unmanned surface vessel (20) to enable the efficient, automated cleanup of oil spills. Such a vessel (20) has the potential to provide a low-cost, modular solution for day-to-day oil-spill cleanup operations, especially in confined aquatic areas, such as under piers and in the small spaces between marine vessels and piers. The smart membranes (14) are provided on the surface of a conveyor belt (34) that circulates the membranes (14) through the surrounding body of water (10) for oil collection, as well as through an internal reduction chamber (22) of the vessel (20) for oil release. The smart membranes (14) are adapted to attract and repel oil (12) in response to low-voltage commands applied across the conveyor belt (34), using a process that is repeatable for a number of cycles, offering high efficiency and long durability (FIG. 5).
