Key Takeaways
  • • Ray Dalio, through his nonprofit OceanX, operates the OceanXplorer, an 87.1-metre (286-foot) research vessel rebuilt from a former oil-field support ship that Dalio acquired around 2016.
  • • The ship carries a maximum crew of 72, four wet and dry labs, media production facilities, a recompression chamber, a resident H125 Airbus helicopter, two crewed Triton submersibles rated to 1,000 m, and a 6,000 m-rated ROV.
  • • Dalio bought the vessel when the oil market had crashed and the ship was only about five years old, then stripped and rebuilt it at significant expense, with James Cameron advising on lighting, design and production facilities.
  • • The OceanXplorer's expeditions are tied to media output, including the six-part OceanXplorers series that premiered on National Geographic on August 18, 2024.

Summary
Ray Dalio's research vessel, the OceanXplorer, is an 87.1-metre (286-foot) ship that was rebuilt from a former oil-exploration vessel. According to supplemental coverage from Alert Diver, Dalio and his son Mark commissioned the ship to succeed the 184-foot Alucia, offering roughly four times the capacity. Publisher snippets describe the vessel as previously operating as the Volstad Surveyor and briefly as Alucia 2.

Dalio acquired the ship in 2016, when the oil market had crashed and the vessel was only about five years old. It was stripped and rebuilt at considerable expense to meet his specifications. Woods Hole Oceanographic Institution provided input on ocean research requirements, and James Cameron advised on the lighting, design and Hollywood-quality production facilities.

The ship carries a maximum crew of 72, four wet and dry laboratories for tasks such as genetic sequencing and microscopy, a recompression chamber, and a resident H125 Airbus helicopter. Its underwater assets include two crewed Triton submersibles capable of 1,000-metre dives, a large ROV rated to 6,000 metres, a mini ROV, and a sonar array able to map to 8,000 metres. Reporting also notes that a former oil-exploration ship operated by OceanX set sail from Singapore on a 24-day study of underwater features.

OceanX, the nonprofit Dalio co-founded and continues to advise, operates the vessel. According to supplemental coverage, Dalio applies a three-part test to projects: strong science, media potential, and cost justification, with philanthropic losses capped annually. The most prominent media partnership is the six-part OceanXplorers series, which premiered on National Geographic on August 18, 2024, with streaming on Disney+ and Hulu.
