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 enviro mental impact by reduction of hydraulic oil volumes while maintaining high power efficiency.

  • Electric-propulsion
  • Work-class ROV
  • Multi-Purpose
  • Electrically Powered ROV
  • System for Drill Support,
  • IMR, Survey and Medium
  • Duty Construction.


  • 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 excellent
    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.
