Utilizing a wide range of applicable ground and improvement purposes to form the foundations of various offshore structures!
We would like to introduce the offshore version of our backfilling sand compaction pile method, "Composer." By utilizing a positioning system that employs VRS-GPS (network-type RTK-GPS positioning), we can measure the position of the work vessel in real-time using GPS, allowing for precise movement and stabilization of the work vessel at the designated placement location. This method involves driving a vibrating casing pipe to a specified depth, then extracting and backfilling it repeatedly to create well-compacted sand piles with a large diameter within soft ground, thereby stabilizing the ground. 【Features】 ■ Wide range of applicable ground and improvement purposes ■ Economical construction method ■ Capable of construction at great water depths and depths ■ Reliable creation of composer piles ■ High reliability in construction management and quality control ■ Utilization of work vessel position and navigation information systems *For more details, please refer to the PDF materials or feel free to contact us.
