The mining vessel YA TOIVO (length overall 149.50 metres) is equipped with a 4 point-mooring-system integrated anchor-assist and a dynamic positioning (DP2) system which combine to safeguard the vessel remaining in station in all weather conditions. The vessel is further equipped with a Remotely Operated Subsea Tractor (ROST), launch and recovery system for subsea tool handling consisting of a large, fixed A-frame over the stern of the vessel and a hoist winch and heave compensator. The mined material is slurry pumped from the sea bed through a special riser system into the fully integrated diamond 150 ton/hour dense media separation (DMS) processing plant.

The mining operations on the vessel are managed 24/7 in an environmentally friendly manner: the material mined from the seabed, once pumped on board, is sorted and processed without the use of any chemical product. Once separated, the oversize and undersize material (i.e. tailings) are re-deposited in the very same locality that the ROST covered during mining. This process has been shown to leave the least evidence of seabed disturbance and favour preservation of the biophysical environment after mining is completed.
