Due to delays in fitting out, repairs to Olympic and bad weather, Titanic began her sea trials on 2 April 1912. The trials began at 0600 (6 am). There were stokers, greasers and fireman along with crew members aboard. Thomas Andrews and Edward Wilding were aboard representing Harland & Wolff. Harold Sanderson represented IMM. Both Bruce Ismay and Lord Pirrie were ill and could not attend. Francis Carruthers from the Board of Trade was also present to see that the ship was fit to carry passengers. Marconi wireless operators Jack Phillips and Harold Bride were also aboard.
The sea trials took 12 hours and tested the ship’s ability to travel at different speeds, turning ability, and ability to stop quickly. Titanic was tested both in the Irish Sea and in Belfast Lough. About 80 miles were covered during the trials. The ship would return to Belfast around 1900 (7 pm.). The surveyor from the Board of Trade signed papers that the ship was seaworthy for the next 12 months.
Titanic would depart an hour later to head to Southampton to take on additional crew, passengers, and supplies.
