  • Product Number: ITE-0027-DR-0001-00
  • Hydrates are a solid structure (similar to water-ice) that is formed when natural gas interacts with water at high ambient pressures and cold environments. i-Tech 7 utilizes hydrate remediation techniques based on a combination of pressure reduction and chemical injection technology to disassociate blockages in subsea production facilities. i-Tech 7 Hydrate Remediation Skid is designed to interface with work class and heavy work class ROVs operating on multi-service vessels or drilling rigs.


    Typical hydrate formation locations

    • Pressure caps
    • Control lines / Control modules
    • Production path 
    • Barrier valves
    • Isolation valves
    • Chemical injection lines
    • Control fluid lines

    Hydrates are dislocated by

    • Reducing pressure to less that 10 BAR
    • Applying chemicals such as methanol or glycol
    • Increasing temperature


    • Enhanced Automated Controls
    • Electrically Actuated Process Valving
    • High Precision Instrumentation
    • System Flexibility
    • Topside Control Software
