Control Spheres

Cyclops class submersible control spheres house all motor control parts, power conversion systems, multiple sensors and Optical-to-Ethernet switches...all controlled via a fiber optic connection to a computer inside the submersible.

Future Cyclops class submersibles will also have our sonar computer, camera controls, communications and batteries outside the carbon fiber pressure vessel.

Thick carbon fiber hulls that OceanGate will use on Cyclops 2 are sensitive to hull penetrations. For example, below the dome on Cyclops 1 are a number of thick cables that exit the hull. These create stress risers and require reinforcement of the steel pressure vessel to be safe.

Carbon Fiber Hulls

Carbon fiber hulls are more sensitive to these localized stresses so it is best to reduce the number, and to make them as small as possible.

This is why our deeper diving Cyclops class submersibles will use fiber optic connections and do all of the heavy switching outside the pressure vessel. This means that a number of parts must remain outside the main hull and many will be need to be kept at surface pressure. These include:

  • Motor controllers
  • Data analysis and collection components
  • Current sensors, and
  • General switching parts
Sphere Material

Titanium or other metal housings that might do this are very expensive and heavy. However, glass housings are only a few thousand dollars each and can take pressures of up to 11,000 meters depth (around 16,000psi).

Oil Filled

For our deep Cyclops class submersibles we will also fill these spheres with non-conductive oil that will help with heat dissipation and reduce risk if the sphere does fail.

Our Subs Are Used For:

Site Survey and Inspection 

Conduct continuous and extensive site surveys to inspect underwater infrastructure, wrecks or sensitive environmental habitats without resurfacing.

Research and Data Collection 

Collect research data in real-time with first-hand views, onboard collaboration and the flexibility to modify your mission profile while still on site.

Film and Media Production 

The ultimate stage to film the treasures of the deep in a highly adaptive vessel designed to illuminate the depths, capture vibrant images and document natural habitat.

Deep Sea Testing 

A unique underwater testing platform to conduct a wide array of experiments to test equipment or expedite sensitive research in deep ocean environments.
