An apparatus and method for securing subsea devices to a seabed are provided. The apparatus generally includes a mud can housing that defines a internal space that can be evacuated to drive the housing into the seabed and secured it thereto. At least one receiver is connected to the housing. Each receiver is configured to receive a subsea device so that each subsea device in each receiver is secured to the seabed in a vertical orientation when the mud can housing is secured to the seabed.

1. An apparatus associated with a subsea hydrocarbon production well, the apparatus being configured for positioning into a seabed, the apparatus comprising: (a) a mud can housing having a circumferential side and an upper side defining a space, the housing having an open bottom;(b) a port in the mud can housing, the port being adapted for passage of water from the space of the mud can housing to facilitate insertion of the mud can housing into the seabed;(c) a plurality of receivers connected to the mud can housing, at least one of the plurality of the receivers defining a substantially vertical cavity therein;(d) a subsea device positioned at least partially within the vertical cavity of one of the receivers, the subsea device being capable of assisting in hydrocarbon production or hydrocarbon transport operations from an associated subsea hydrocarbon well;(e) wherein the subsea device is selected from the group of devices consisting of: pump, sensor, separator, pig launcher, pig receiver, tubing, hanger, and packer; and(f) wherein the subsea device is configured for facilitating addition or removal of the subsea device from one of the plurality of receivers upon the mud can housing while the mud can housing is secured to the seabed. 2. An apparatus according to claim 1 wherein at least two of the plurality of receivers connected to the mud can housing are configured to receive respective subsea devices. 3. An apparatus according to claim 1 wherein the plurality of receivers are spaced about a perimeter of the circumferential side of the mud can housing and are connected to the circumferential side of the mud can housing. 4. An apparatus according to claim 1 wherein at least one of the plurality of receivers is configured to receive subsea device through an opening defined in the top of the apparatus such that subsea devices can be installed in the apparatus and removed from the apparatus while the housing is secured to the seabed. 5. An apparatus according to claim 1 wherein at least one receiver of the plurality of receivers comprises an orientation feature configured to rotate the subsea device that is lowered into the receiver such that the subsea device is rotatable to a predetermined orientation when installed in the one receiver. 6. An apparatus according to claim 5 wherein the orientation feature of the one receiver comprises a connector configured to mate with a corresponding connector of a subsea device installed in the receiver, the respective connectors being configured to provide electrical conductivity or fluid connection. 7. An apparatus according to claim 6, further comprising a manifold configured to fluidly connect at least one subsea device to the port on the mud can housing. 8. An apparatus according to claim 1 wherein the mud can housing is secured to the seabed and further comprising a plurality of subsea devices, each subsea device disposed in a respective one of the plurality of receivers, and each of said respective subsea devices extending both above and below the upper side of the mud can housing. 9. An apparatus according to claim 8 wherein the plurality of subsea devices comprises at least one separator and a plurality of subsea pumps, the apparatus being configured to: i) receive a flow of fluid from a well in a subsea hydrocarbon production well;ii) separate different phase components of the fluid; andiii) deliver at least some of the components of the fluid at an increased pressure. 10. A method for securing subsea devices to a seabed, the method comprising: (a) positioning a mud can housing on the seabed, the mud can housing having a circumferential side and an upper side that defines a space therein, a plurality of receivers being connected to the mud can housing, at least one of the plurality of the receivers defining a substantially vertical cavity therein, the mud can housing having an open bottom, the mud can housing further providing a port, the port being adapted for passage of seawater out of the mud can housing;(b) evacuating seawater from the space within the mud can housing through the port;(c) driving the mud can housing into the seabed to secure the mud can housing to the seabed; and(d) positioning a subsea device at least partially within the cavity of one of the plurality of receivers, the subsea device being capable of assisting in hydrocarbon production or hydrocarbon transport operations from an adjacent subsea hydrocarbon production well, wherein the subsea device is selected from the group of devices consisting of: pump, sensor, separator, pig launcher, pig receiver, tubing, hanger, and packer.
