The Olympic was the Sister ship to Titanic. After the incident with HMS Hawk she was no longer viable as an ocean going vessel. Because the accident was determined tobe the fault of White Star lines, Insurance money was not paid out. White Star was in dire straits with the loss of their investment. She was gantried next to Titanic and adjusted to look exactly like her. Their names and registration were swapped. The Titanic became the the Olympic and vice versa. It was the plan of the White Star Lines to pass off Olympic as Titanic and cause her to have an 'accident' thereby collecting the insurance they would otherwise not have gotten. The re-named Titanic was left to masquerade as the Olympic.
