Elsub

The ELSUB electrically powered WROV system delivers outstanding reliability and versatility in a powerful and compact package. The electric thrusters are individually powered and controlled from topside, offering a significantly reduced environmental impact by reduction of hydraulic oil volumes while maintaining high power efficiency.

Key Information

  • User friendly computerized power, control and communications systems located topside provide maximum flexibility in configuration and application. Additional auxiliary electric power and communications channels are built into the system.
  • Simple, rugged design together with low component count on the ROV and redundancy in the propulsion system contribute to excellen t continuity of operational service under demanding conditions.
  • High power with precise control and instant response.
  • Stable, versatile platform for a wide range of tooling and accessories.
  • High thruster performance with quiet acoustic signature ideal for survey.
