1. A well system, comprising:
- an assembly providing a bore in communication with a wellbore;
a device operable to shear a tubular disposed in the bore; and
a shutter device located below the device comprising adjacent rams located circumferentially about the bore, each of the adjacent rams having a plate with a front face, the shutter device operable between an open position with the plates withdrawn from the bore to a closed position with the front faces of the plates contacting the tubular in the bore and the plates of the adjacent rams overlapping one another, wherein the plates do not seal against the tubular, wherein the plate of each of the adjacent rams comprises two or more plates that are stacked and spaced vertically apart whereby in the closed position the two or more plates of the adjacent rams interleave one another.

- 11. A device, comprising a bore and adjacent rams located circumferentially about the bore, each of the adjacent rams comprising a plate having a front face, the adjacent rams in use operable between an open position with the plates withdrawn from the bore to a closed position to contact a tubular that is disposed in the bore with the front faces of the plates, wherein in the closed position the plates of the adjacent rams overlap one another and the plates do not seal the bore, wherein the plate of each of the adjacent rams comprises two or more plates that are stacked and spaced vertically apart whereby in the closed position the two or more plates of the adjacent rams interleave one another.
- 15. A method comprising actuating a shutter device comprising a bore in communication with a wellbore from an open position to a closed position, wherein the shutter device comprises adjacent rams located circumferentially about the bore, each of the adjacent rams having a plate with a front face, wherein in the open position the plates are withdrawn from the bore, and in the closed position the front faces of the plates are contacting a tubular that is disposed in the bore without sealing the bore and the plates of the adjacent rams overlap one another, and wherein the plate of each of the adjacent rams comprises two or more plates that are stacked and spaced vertically apart whereby in the closed position the two or more plates of the adjacent rams interleave one another.
