Geotechnical Survey Completed in SMS Site

Unicorn-1

Fukada Salvage and Marine Works (Fukada) completed a short coring program in 1,400m of seawater and wave heights of up to 2.5m off the coast in Japan. The program focused on recovering Seafloor Massive Sulphides (SMS) samples to help better understand the geology of the region.

Cores were taken at 6 locations to sample depths ranging from 9m to 63m. The geology of the region is highly varied ranging from silts and clay to soft volcanic ash to quartz and rock. This variation has resulted in poor core recovery on previous drilling programs. The Unicorn-1 system was able to recover excellent core recovery particularly in the SMS segment with core averaging over 70% recovery.

The Unicorn-1 system is a highly capable seafloor drilling platform suitable for operation to 3,000m of seawater and the ability to operate safely in highly variable weather conditions due to its purpose-built A-frame and heave compensated winch.
