Abstract: A system comprising: a mooring bridle, wherein the mooring bridle is installed below the wave zone of the sea and wherein the bridle is attached to a first vessel; and vessel lines which attach a second vessel to the mooring bridle. A line comprising: an anchor which is attached to the sea floor; an anchor line comprising an upper end and a lower end wherein the lower end is connected to the anchor; an anchor line buoy which is attached to the upper end of the anchor line; and a vessel line comprising an upper end and a lower end wherein the lower end attaches to the buoy and the upper end attaches to the vessel.

Abstract: A method for monitoring production mineral reservoirs, the method comprising: permanently installing a geophone in a borehole; generating a first set of seismic waves; receiving a first set of seismic data with the geophone; recording the first set of data of said receiving a first set of seismic data; generating a second set of seismic waves after sufficient time has passed for conditions in the reservoir to have changed from the generating a first set of seismic waves; receiving a second set of seismic data with the geophone; and recording the second set of seismic data of said receiving a second set of seismic data. A method for installing instruments below the surface of the earth, the method comprising: drilling a borehole with a drill apparatus; inserting an instrument in the borehole; and permanently fixing the instrument in the borehole.
