A mobile HEB and TEP mitigation device includes a mobile body capable of movement within or upon a body of water. Located within the mobile body is a hydrodynamic separation system which includes a water inlet, a hydrodynamic separation unit and a collection tank. The hydrodynamic separation unit includes two outputs, one for a clean stream output line containing clean water and arranged to re-circulate the clean water, and another for a concentrate stream output line, the concentrate stream output line configured to place concentrated water containing potentially harmful bio-organic materials into the collection tank. Also included on the mobile body is a power source and an engine/steering unit, wherein the steering portion of the engine/steering unit provides a capacity to move the mobile body in an intended direction. The mitigation device may also be used as an embedded part of an on-shore arrangement.

A marine emergency rescue transfer system includes a water navigation robot. An attracting device configured to attach and fix with an accident ship is installed on one side of the water navigation robot. An automatic lifting device is installed on the water navigation robot. A fixing sealing device is installed on the automatic lifting device. The automatic lifting device is installed on the automatic lifting device. The fixing sealing device includes a box body and a vacuum pump. The box body defines a cavity. The vacuum pump is configured to pump air or water in the cavity, so the box body is fixed on the accident ship through atmospheric pressure or water pressure. The rescue devices are placed in the fixing sealing device. The remote control grippers are installed on the automatic lifting device. The remote control grippers are configured to grip the rescue devices for transfer operation.
