Oxygen Systems and Safety for New-Build Raja Ampat Dive Boats
Raja Ampat’s remoteness is the design driver for every dive-safety system on a new-build. Evacuation from Misool or Wayag is measured in many hours, and the nearest recompression facility is a serious journey away.… Read the note →
Air Conditioning and Ventilation Design for Raja Ampat Liveaboards
