1. An apparatus comprising: a tubular suction pile;an indenter housing that surrounds the tubular suction pile,wherein the indenter housing is configured to be sunk into a seabed in response to a negative pressure created from water being removed from the tubular suction pile, and the indenter housing is configured to create a trench in the seabed; anda water jetting device, within the indenter housing, that includes a first valve, a nozzle, anda channel that connects the first valve to the nozzle. 2. The apparatus of claim 1, wherein the indenter housing is a wedge shaped body. 3. The apparatus of claim 1, wherein the water jetting device is configured to expel water from the nozzle without using a pump device. 4. The apparatus of claim 2, wherein the wedge shaped body has a trapezoidal cross-section. 5. The apparatus of claim 4, wherein the nozzle is disposed on tapered section of the trapezoidal cross-section. 6. The apparatus of claim 1, wherein the water jetting device is disposed in a leading portion of the indenter housing. 7. The apparatus of claim 2, wherein the wedge shaped body is directly connected to the tubular suction pile. 8. The apparatus of claim 1, further comprising: a vibration device,wherein the vibration device is configured to impart a longitudinal vibration to the indenter housing that sinks the indenter housing into the seabed. 9. The apparatus of claim 1, further comprising: a second valve connected to the tubular suction pile, wherein the second valve is configured toallow water to be pumped out of the tubular suction pile. 10. An apparatus comprising: a vibration device; andan indenter housing that surrounds the vibration device,wherein the vibration device is configured to impart a longitudinal vibration to the indenter housing in a direction substantially perpendicular to a seabed, and the indenter housing is configured to be sunk into the seabed in response to the longitudinal vibration and is configured to create a trench in the seabed. 11. The apparatus of claim 10, wherein the indenter housing is a wedge shaped body. 12. The apparatus of claim 11, wherein the wedge shaped body has a trapezoidal cross-section. 13. The apparatus of claim 11, wherein the wedge shaped body is directly connected to the vibration device. 14. The apparatus of claim 10, wherein the vibration device includes a hydraulic system. 15. A method comprising: lowering or dropping an indenter into a body of water, wherein the indenter includes a tubular suction pile,a housing that surrounds the tubular suction pile, anda water jetting device, within the housing, that includes a first valve, a nozzle, anda channel that connects the first valve to the nozzle;sinking the indenter into a seabed after the indenter comes to rest at a bottom of the seabed, the sinking including creating a negative pressure by removing water from the tubular suction pile, wherein the negative pressure causes the indenter to sink to a predetermined depth in the seabed;causing water to exit from the indenter, the water loosening soil in the seabed; andcreating a trench in the seabed by pulling or pushing the indenter after the indenter is sunk into the seabed and the soil is loosened by the water. 16. The method of claim 15, further comprising: laying a pipeline in the trench. 17. The method of claim 15, further comprising: using a computer to control the negative pressure in order to cause the indenter to sink to the predetermined depth in the seabed. 18. A method comprising: lowering or dropping an indenter into a body of water, wherein the indenter includes a vibration device, anda housing that surrounds the vibration device;causing the vibration device to impart a longitudinal vibration to the housing, the longitudinal vibration induced in a direction substantially perpendicular to a seabed and causing the housing to sink to a predetermined depth in the seabed; andcreating a trench in the seabed by pulling or pushing the indenter after the indenter is sunk into the seabed. 19. The method of claim 18, further comprising causing the vibration device to impart a longitudinal vibration while the creating the trench step is performed. 20. The method of claim 18, further comprising: using a computer to control the vibration device in order to cause the indenter to sink to the predetermined depth in the seabed.
