Offshore recovery differs from land recovery in that offshore recovery requires the pod to float on the surface of the sea with the payload, while land recovery does not. After the pod falls on the sea surface, the pod needs to keep a long-time floating state for search and rescue personnel to find conveniently, so that the pod needs to have good sealing property and floatability; unlike land reclamation, the position of the nacelle will change as the ocean currents change, which makes positioning of the nacelle after it has landed more difficult.
