Limitations of existing offshore DCM equipment In ASIA
1. Limitation of Ground applicability - In the ground layer with N value of 15 or higher, workability decreases due to lower drilling speed.
2. Mudball formation - Due to the entanglement between the original ground and the stirring bit in the high-adhesive clay ground Construction quality deterioration due to the occurrence of cement stirring problems Reduced construction speed due to overload of auger Due to the formation of mud balls on the stirring bit, the cleaning time for mud balls increases and construction speed decrease
1. Yoon&Plac is the World's first DCM construction from 0 to N 50 in the world at Incheon International Passenger Terminal construction, quality check Increase work efficiency, improve DCM cluster quality and reduce cost through hard ground DCM. Yoon & Plac's DCM high-speed rotation construction can be constructed at 40 to 60 RPM, which is about two times faster than typical marine companies' DCM high-speed rotation speed.

2. Yoon&Plac's Mudd ball solution - Blade and Jet water system
Blade Design - The sleek structure is advantageous in disturbing the clay. - Water jet-capable design allows excavation of hard ground 2. Special coating - Use special coating on stirring bits and blades Minimize mudball formation.

Construction speed is 20 to 50% faster on average than other companies. Can reduce cement by 30 to 40% less cement. It is possible to secure competitiveness in winning Marine and Land DCM orders. We want to proceed with the global DCM project. (Yoon & Plac processed three offshore DCM vessels for the first time in Korea)
