Zusammenfassung:	Applicants have created a method and system of deep sea mining comprising mining SMS deposits from the sea floor with a subsea miner, pumping the solids from the subsea miner through a jumper and pumping the solids from the jumper up a riser to a surface vessel. Further, applicants have created a method of deploying a deep sea mining system, comprising stacking a riser hangoff structure on top of a subsea pump module forming an assembly; picking up the assembly by a hanging mechanism, hanging the assembly on a moon pool, attaching a first riser joint; disconnecting the riser hangoff structure from the assembly; and attaching at least one second riser joint to form the riser.
