Project Description
When operating at full capacity, Jeonnam is projected to provide renewable energy to around 60,000 households.
Project name: Jeonnam Offshore Wind Farm Phase 1
Location: 15 km offshore of Jaeun-do, Jeonnam, South Korea
Year: 2024
Application: Monopile foundations
Project Requirements
Hyundai Engineering Steel Industries (HESI), in partnership with the developer JOWP, engaged Sika to supply grouting materials and services for the project. Out of the ten monopile/transition piece (MP/TP) wind turbine foundations, three required grouting. Each foundation consists of a monopile and an insert pile, with the monopiles driven into position before drilling and installing the insert piles. Once the insert piles were in place, grouting was necessary to fill the annular space between the rock, insert pile, and monopile.
Sika Solutions
Sika supplied grout material in 8.2 MT uFIBCs, two (2) ComPact45 offshore grout spreads, on-site QC Mobile Laboratory and a skilled offshore grouting team.
- 1st pile - FOU06 completed with a grout volume of 688.8 MT applied.
- 2nd pile - FOU03 completed with a grout volume of 885.6 MT applied.
- 3rd pile - FOU04 completed with a grout volume of 656 MT applied.
- Total material quantity applied: 2,230 MT
Customer Benefits
- This was the largest grout volume for an offshore wind monopile foundation in a single operation, setting a new industry benchmark.
- The two cutting-edge CPT45 offshore grouting spreads delivered an impressive output of over 30 m³ per hour.
- Both grouting systems operated in tandem, resulting in a seamless execution and reducing downtime.
- The application of SikaGrout®-9550 significantly reduced tower base installation waiting time by exceeding the required 60 MPa grout strength within 24 hours.
- Sika’s advanced materials and expert offshore grouting team ensured optimal foundation stability and long-term performance and a smooth project execution.
