A subsea grab system (100) comprises a grab device (110); a first hoisting arrangement (120) for the grab device; a driver device (130) comprising a propeller system (132) for positioning the driver device in a first horizontal plane, the grab system being configured such that the grab device (110) is positioned below the driver device (130), and the driver device being configured for positioning the grab device (110) in a second horizontal plane by guiding of the first hoisting arrangement; and a second hoisting arrangement (140) for the driver device. The first and second hoisting arrangements (120, 140) are configured and arranged such that the grab device (110) and the driver device (130), during operation, are independently suspended from the marine vessel (10), and may comprise cables, chains (121) or wires (141) for suspending and hoisting the grab device (110). |
