Who designed boarding ladder after the ship was launched in the shipyard? Or which department designed the shipyard?

You are talking about the pilot boarding gangway, which has been designed in the detailed design of the ship. You ask who designed it, depending on who designed the overall design of the ship, not necessarily the shipyard, because many shipyards don't have their own design departments now, but only buy drawings; However, the general manufacturers are all designed by their own design institutes, or the ship research institute is all designed by themselves. But it mainly depends on which company designed the overall design of this ship, not necessarily the shipyard.
