Our expeditions are deeply researched, planned, and executed to ensure the greatest of care and concern for the safety of our crew, respect for Titanic and the wreck site, and environment. It takes between 2 and 2.5 hours to reach the bottom of the ocean where the Titanic wreck site lies, about 2.5 miles below the surface. The exact length of the expedition depends on the objectives of the mission, the weather conditions, and other factors. The primary objective is the safety of all involved in the expedition.
