Rexroth Solution:

Create complete electro-hydraulic systems using standard but customizable materials.

Key Insights & Considerations:

  • Underwater equipment is less accessible, so it should be reliable and durable to minimize the need for maintenance
  • Ensure that systems are able to withstand high water pressure and harsh ocean conditions while remaining corrosion-resistant
  • Account for sea life growth, which is common in shallow water that receives surface light
  • Consider using floating operational facilities like ships or platforms so workers can conveniently access equipment far from the shore
  • Use robotics like ROVs and AUVs to conduct subsea activities
  • Set up remote devices for operating subsea systems at a distance
  • Use pressure compensation systems to equalize the pressure inside the component to the outside pressure
  • Use a special coating on each component to avoid corrosion
  • Take safety and reliability measures by creating and utilizing fail-safe systems, redundant architecture and diagnostic features to help in the event of a failure
