The Planet Ocean Underwater Hotel operates at one atmosphere, the same internal pressure as sea level. This eliminates decompression sickness, nitrogen loading, and complex saturation risks associated with deep-sea habitats.

Why One Atmosphere Matters

• No decompression chambers required
• No saturation diving exposure
• Safe for scientists, guests, regulators, and media

30-Foot Operational Depth

All standard operations occur at approximately 30 feet, enabling extended underwater occupancy while maintaining simple emergency ascent capability.

Ballast and Elevation Safety

The vessel can raise the underwater module to 26 feet or higher during swell or weather events, reducing kinetic energy exposure.

Regulatory Alignment

This protocol aligns with maritime safety doctrine, insurance underwriting requirements, and Florida Department of Environmental Protection approvals issued in 2018.
