MUMBAI, India, Jan. 2 -- Intellectual Property India has published a patent application (202541124184 A) filed by Sri Krishna College Of Engineering And Technology, Coimbatore, Tamil Nadu, on Dec. 9, 2025, for 'floating and gas-filled expandable bladder system with self-adjusting buoyancy regulator and one-way valve for autonomous oil spill recovery.'
Inventor(s) include Dr R Ganesh; Dr S Sundararaj; Lokeesh B; Deelipraj D; Anbuselvan G; and Srihari S.
The application for the patent was published on Jan. 2, under issue no. 01/2026.
According to the abstract released by the Intellectual Property India: "The invention provides a floating, autonomous oil spill recovery vessel consisting of a buoyant gas-filled chamber (5.2), a flexible expandable oil bladder (5.3), and a passive one-way valve (5.1) incorporating a spring (2.1), ball (2.2), and perforated holes (4.3) for unidirectional oil intake. The system collects surface oil without pumps or power, with the bladder expanding according to the incoming volume. The surrounding gas chamber maintains buoyancy through a gas inlet (5.5), while rope guides (5.4) enable towing and anchoring. Oil enters through the oil path (3.1), guided by the floating ring (3.2) and valve seat (3.3). A novel Self-Adjusting Buoyancy Regulator (SABR) inside the gas chamber redistributes internal gas to maintain stability during load variation. The vessel operates in harsh marine conditions, is reusable, scalable, and capable of storing at least 500 kg of oil, providing an efficient and eco-friendly spill recovery solution."
