Supporting the energy transition with sustainable E-CFE^® solutions

• We have taken radical steps to reduce the CO2 footprint of our offshore operations
• Next generation thinking – looking to the future

HYDROMOLE allows intervention for multiple seabed applications and soil conditions and is operable at significant water depths without reduction in performance thanks to an all-electric system architecture. 

With a 400kW all-electric twin tool arrangement, HYDROMOLE provides a step change in performance, efficiency, and versatility in both shallow water and deep-water (1.5 to 2,500m) excavation and trenching applications.

• Major reduction in CO2 emissions
• No risk to the marine environment from high pressure hydraulic oil spills
• Negligible noise pollution when electric power unit is operational
• Significantly increased vessel back deck safety during operations
• Optimised system performance with surface and subsea diagnosis and datalogging
• Dramatic increase in project operation uptime and reliability
• One lightweight umbilical for all system power, controls & survey packages
• Full power available at the E-CFE^®, regardless of water depth

• Water depth operability – 1.5m to 2,500m
• Maximum flow volume – 6,000 L/s
• Maximum flow velocity – 12m/s at 3m from nozzle outlet
• Pressure at nozzle outlet – 7.5psi (at full flow)
• Cuts soils up to 50kPa @ 3m as standard, and 200kPa+ with high pressure jetting
• Suitable for variable seabed conditions from sand, clays, silt, gravel and rock dump
