"Titanic Liverpool"
Liverpool was to be the registered home port of the Titanic. The home port is marked on the ship.
for hull saftey, because of the titanic
By far, the largest part of Titanic was her hull.
The upper decks which make up the superstructure of Titanic are made with 1/4" steel. The hull itself is an inch thick.
The steel plates of Titanic's hull measured six feet high by thirty feet long.
It meant to strengthen the ship. Titanic's steel hull, the main body of the ship, had been reinforced with a second hull fitted inside. That is why people used to say the Titanic was unsinkable, so this belief lulled everyone on board into a false sense of security, which was to have tragic consequences.
