Salvaging a sunken ship in the high winds and rough waves of the open sea is by no means an easy task.
First you have to locate where the wreck lies; once you find it, you must use underwater detection equipment to clarify the conditions on the seabed, and may even have to send divers down to survey it, then work out a salvage plan. No matter how advanced the equipment, if you want to haul a ship up from the seabed, the quickest it can be done is still about a month and a half.
Hai Xun 49 drifted and cruised in the wreck area for two days, during which they only saw one anti‑submarine aircraft of the Japan Maritime Self-Defense Force fly over twice.
Han Yu did not continue to stay in the wreck area; in accordance with his superior's orders he formally launched the "ice‑breaking journey" of Binjiang Maritime Bureau and even Jiangnan Maritime!
