Safety Features and Innovations
All systems and designs will be certified to DNV-GL Rules for Classification and Construction of Manned Submersibles. This means that every detail of its design and manufacture will be certified according to very stringent requirements. Meeting this standard alone will dictate that each Hyper-Sub built will be incredibly safe. The Hyper-Sub MSV, however, goes well beyond standard safety requirements through the use of characteristics that have been captured in its design.
Safety features include:
Three independent methods of surfacing: Normal operating system surfacing, Emergency drop tray surfacing (3,000 lbs/1361 kg) and Controlled Dead Systems Submerged Recoverability (boat can surface with all primary air, electrical and hydraulic systems shut down in a controlled fashion)
Passive safety characteristics such as Hyper-ballast compartmentalization (8 separate compartments) retaining over 30,000 lbs (1,361 kg) of total reserve submerged lift for rapid accents in the event of the most severe emergencies
Sufficient reserve air to blow MBT’s 2 times @ 500’ (152 m) depth using standard air loads
Submerged EPIRB and VHF antennae deployment location and communications capability
Atmospheric monitoring system Various (H2, O2 & CO2), Life support (CO2) Maintained at less than 0.5 %, Life support (O2) Maintained between 19-22 %
Emergency life-support: 48 hours per passenger
Emergency re-breathers: (1) per crew-member
Life jackets: (1) per passenger
Emergency drinking water, lifeboat rations, waste & CO2 removal equipment
Dual frequency underwater telephone
Robustness of cabin (with integral integrity to withstand pressures at depth) protect crew from wave action during surface operations in rough seas
Very low center of gravity for surface craft stability in rough seas
Fire extinguishing systems: Engine compartment / Halon auto dump
Surface navigation lights (x 6) 12 Volts/25 Watts each
Dead System recovery: Having access to 30,000 lbs. of lift, separated in 8 different compartments means that a Hyper-Sub can still be return to the surface, in a controlled way, even in the even of total systems failure, including electronics, hydraulics and other functionality. This feature is in a addition to the emergency drop weight required by class societies.
Rapid accent: When submerged, having access to 30,000 lbs. of lift insures a very rapid accent capability if needed in an emergency.
Cabin flooding: Having access to 30,000 lbs. of lift means that the Hyper-Sub can return to the surface even if the cabin were completely flooded.
Emergency event negation: Having access to 30,000 lbs. of lift means that the Hyper-Sub can return its cabin to a position ABOVE the waterline, ending any crisis due to through-hull penetration failure.
Surface craft functionality: Having access to 30,000 lbs. of lift means that the Hyper-Sub can resume access to its surface craft functionality and therefore does not need to be recovered (lifted onto a larger vessel) in order for its occupants to be safe.
Hyper-Buoyancy (or Hyper-Ballasting) also means that:
The Hyper-Sub can place its hatch four feet above the waterline, meaning that once surfaced, the crew can ingress and egress the compartment without swamping the vessel.
The Hyper-Sub can carry all dangerous materials or systems outside of its cabin.
The Hyper-Sub, by having the capability of carrying a full compliment of surface vessel components (in addition to its battery powered sub-sea components) means that diesel power propulsion can be accessed once surfaced in the event of subsurface electrical / battery failure.
As a surface vessel:
The Hyper-Sub can carry an incredibly robust cabin that (being capable of withstanding pressures at 500 feet or 1,200 feet) can withstand severe wave action during surface operations for crew protection in extreme conditions.
The Hyper-Sub is technically double hulled, meaning that if the surface hull was breached for some reason, the ballast system (over 8 separate compartments) would also have to be compromised before sinking.
The Hyper-Sub can provide 48 hours of life support in the event of sinking.
The Hyper-Sub, if inverted during extreme weather conditions, can submerge and right itself.
Though there are many additional safety features found in the Hyper-Sub, when considered in combination with the proven safety of Class Society design requirements, the safety of a Hyper-Sub render the craft rugged and capable of extended use with relatively minor regular maintenance.
The Hyper-Sub truly is "Something Else Entirely"
