Andrea Doria Survey Expedition: 2017

OceanGate has been contracted by OceanGate Expeditions to provide a manned submersible and marine operations team on an expedition to survey the iconic wreck of the Andrea Doria, an Italian flagged passenger liner that sank near Nantucket, Massachusetts after colliding with the Stockholm, a Swedish passenger vessel outbound from New York.

The primary objective of the 2017 Andrea Doria Survey Expedition was to capture additional sonar images of the shipwreck to document its current condition. The expedition goal is to establish accurate and reliable baseline data so explorers and scientists can better assess the decay of the wreck over time.

This iconic shipwreck has been explored by scuba divers and mixed-gas divers for decades – with the first dive occurring within hours of the sinking. These scuba dives have resulted in limited views of the wreck due to the short bottom time available to divers (approx. 20 minutes per dive) and limited visibility.

Because divers can only spend a few minutes at depths of 240 feet, and because water turbidity limits visibility to a few dozen feet, it is nearly impossible for divers to capture images of the full scope of this 697 foot long shipwreck. Divers just cannot spend enough time or see well enough to fully view the wreck. Plus, as the ship decays, the familiar landmarks that divers use to navigate around the vessel are changing or disappearing. As a result there are no images that fully illustrate the scope of the wreck in its current state.

The 2017 Andrea Doria Survey Expedition will attempt to change the current state of knowledge of the wreck with sonar images collected from the 5-man submersible Cyclops 1. The expedition team will image the vessel and debris field immediately around the wreck, including:

  • 3D sonar scans that may be digitally assembled into a virtual model of the wreck
  • 2D downward looking sonar video of the length ship as the submersible does a ‘fly-over’ to perform multiple imaging transects
  • 2D sonar with a range of up to 100 meters
  • Video and photographs of the wreck and artifacts (depending on water clarity)
