  • Offshore Windfarm
  • Subsea Jacket Installation


  • Grouting of Offshore Jacket Installation using NaX® Q140-E UHPC grout.
  • Supply of all grouting materials and equipment.


  • Supply of materials and offshore grouting.


  • Due to challenging climatic conditions the project required grout compressive strength of 90 MPa prior to installation of topside module onto jacket structure.


  • Despite very low sea temperature at 5 degrees Celsius during project execution, the average compressive strength under identical on-site curing condition exceeded the strength requirement within the first week.
