Epoxy Grouting Four New IHI BOG Compressors

Download Success Case

During Summer 2017, Alphatec Engineering collaborated with Premonor S.A at Fluxys facilities in Zeebrugge, Belgium, to install epoxy grout for four new BOG IHI compressors.

These compressors, each with a capacity of 12,600 kg/h, required precise alignment and meticulous surface preparation to ensure the secure installation of their frames and motors.

4 x BOG IHI Compressors: Model 32HF-4N-CM

01 Project Details

The installation involved grouting the compressor skids using Alphatec®800 epoxy grout. The process required isolating each anchor bolt with PE foam and sealing the formwork with epoxy putty to prevent any leakage during pouring.

Key steps included:
• Thoroughly cleaning the surfaces using a blower and vacuum to remove debris and dust.
• Accurately aligning the compressors and their frames in accordance with the manufacturer’s specifications.

02 The Grouting Process

Once the compressors were installed, the formwork was set up, and anchor bolts were isolated to avoid direct contact with the grout. The grout was then poured from a single point to avoid creating cavities or air pockets that could compromise the structural integrity of the installation.

The epoxy grout was allowed to cure for 24 hours under controlled temperature and humidity conditions, achieving a compressive strength of 100 MPa.

03 Conclusion

The success of the project was achieved by combining thorough surface cleaning, precise alignment, and careful epoxy grout application.

By eliminating air pockets and properly isolating anchor bolts, the team established a stable and high-strength foundation for these critical LNG compressors, ensuring long-term performance and safety.
