No one could have known that in less than two weeks she would be 12500 feet down at the bottom of the Atlantic Ocean broken in two pieces. 2022 April GMDSS Services – Lecture 1 12/93 2022 April GMDSS Services – Lecture 1 13/93 2022 April GMDSS Services – Lecture 1 14/93 2022 April GMDSS Services – Lecture 1 15/93 2022 April GMDSS Services – Lecture 1 16/93 On Thursday April 11th the Titanic arrived in Queenstown in Ireland around lunchtime. That afternoon she sailed from Ireland for America. From Sunday morning, her wireless operators were receiving many warnings of icebergs ahead. 2022 April GMDSS Services – Lecture 1 17/93 At 10:00pm that evening the bridge watch changed and the new crew was headed by First Officer Murdoch. At 11:40pm a call came from the crow39。s nest Iceberg right ahead. Murdoch ordered full stop, then full astern. At the same time he ordered a hard turn to port. Keep in mind that this order actually made the collision more certain. A short time later Captain Smith arrived on the bridge and asked Murdoch what had she hit. Captain Smith ordered various officers to check for damage assessment. 2022 April GMDSS Services – Lecture 1 18/93 A few minutes later damage reports started ing in, disastrous news for Captain Smith, at least five, possibly six of the watertight partments were flooding. Thomas Andrews, the ship designer had also made his way to the bridge and did not take long to confirm that she could not survive and would inevitably sink within a few hours. 2022 April GMDSS Services – Lecture 1 19/93 2022 April GMDS
