Hi Paul,
The quick repair time of the Olympic and coincidence that it was completed the day before the keel of Britannic was laid was hardly good publicity for White Star.
The celebrated inquiry into the incident lasted well into two months, and after hearing testimony from all involved, decided in Hawke's favor finding Olympic at fault. White Star's appeal of the decision encouraged a firestorm of negative publicity and controversy.
Even considering that the Olympic was under the command of a Trinity House pilot and not White Star officers at the time of the collision, White Star was still held liable and ordered to pay exorbitant legal fees in addition to the cost of repairing the Olympic.
So to answer your question, I think it was in the best interest of both WSL and H&W to get the O back in service as quick as possible to recoup the millions of dollars in lost operational income as quickly as possible.
Best Regards,
Brian
