Yes, placing olivine accurately is almost the exact equivalent of vacuum dredging, but in reverse.
You could dump it with a huge Panamax class vessel, but it you'd end up with the drop too far from the shore, and probably too bunched up, too. With a smaller ship, like a dredger, you'd get the distribution you need. Added to which, the materials handling costs are going to be almost exactly right, because with dredging you're pulling material out of the sea in an arbitrary but nearshore location, and moving it to the nearest port with a rail head where you can get rid of it. It's olivine backwards.
