Thermotite ULTRA

Superior Subsea Insulation

Thermotite® ULTRA is a styrenic alloy-based subsea insulation system designed for flow assurance.

System Description:

  • Layer 1,2,3: 3-layer anti-corrosion system - Fusion Bonded Epoxy, ULTRABond and ULTRA Solid
  • Layer 4: Thermal insulation- ULTRA foam/solid
  • Layer 5: Mechanical and UV protective layer- ULTRAShield

Superior Insulation Properties and Unmatched Mechanical Performance

  • Lower thermal conductivity of both solid and foamed systems result in lower achievable U values
  • Extended cool-down time
  • No glass microspheres:
    • Zero risk of compromised thermal performance due to glass breakage or degradation during service
    • Superior insulation performance without glass enables unlimited depth installation
  • Incompressibility of solid system allows unlimited water depth installation
  • Higher insulation density coupled with reduced thickness improves seabed stability of flowlines and assists in optimizing hydrodynamic response of risers
  • Thinner insulation and reduced pipe profile results in lower lay strains and improved hydrodynamic response

Installation

  • Can be installed using all subsea laying methods including reeling, S-lay and J-lay
  • Superior low temperature ductility enables lower temperature reeling and increased flexibility in installation schedule
  • Lower thermal conductivity translates to reduced insulation
  • Thickness and potential savings in transportation and installation costs

FJ Compatibility

  • Thermotite® ULTRA
  • Nemo 1.1
  • Nemo 2.1

Value Added Services

  • Compatibility with direct electrical heating systems (DEH)
  • Streamlined delivery schedules, product standardization and quality assurance practices due to simplified processing operations
  • Universally and readily available project management and logistics support from multiple existing plant locations
