Abstract: A retriever system for retrieving a marine equipment. The retriever system comprises a hollow body having a first opening, a cap adapted to close the first opening of the hollow body and adapted to be removed. A buoyancy assembly housed in the hollow body and adapted to exit the hollow body when the cap is removed. A linkage system maintains the buoyancy assembly linked to the hollow body of the retriever system. The buoyancy assembly comprises first inflatable element and a second inflatable element, and an inflating system configured to, when activated, inflate the first inflatable element, so as to enable exiting of at least the second inflatable element of the buoyancy assembly out of the hollow body. Said inflating system is configured to start or to continue inflating the second inflatable element when said second inflatable element is out of the hollow body.
