The Planet Ocean Underwater Hotel is engineered with a zero-discharge policy. No sewage, greywater, food waste, chemicals, or fuel byproducts are released into the ocean.

Contained Systems

• Sewage stored within barge containment
• Greywater fully captured and treated onshore
• Solid waste removed and processed ashore

No Anchors, No Reef Damage

The vessel never anchors to the seabed. Positioning is maintained using electric azimuth propulsion and ballast systems, preventing coral scarring.

Marine-Safe Lighting

Interior and exterior viewing uses proven deep-red, non-disruptive lighting that does not interfere with coral spawning or nocturnal marine behavior.

Designed for regulators, marine scientists, and coastal authorities
