A mobile offshore drilling unit (MODU) jacking system includes a plurality of hydraulic continuous linear motion motors, preferably comprising a plurality of phased hydraulic piston/cylinder units, that are engaged with a plurality of MODU supporting legs to provide continuous relative motion between the MODU platform and its supporting legs, and to also maintain the MODU platform and MODU supporting legs locked in a stationary relationship. In the preferred jack-up system, the number of hydraulic piston/cylinder units and the number and design of the teeth that are engaged in providing relative motion may be combined to substantially reduce material stresses on the system.

A method as in claim 7 including the steps of: j. attaching an anvil having a pre-determined diameter from engagement of said pipe casing section to be driven and said hammer including a anvil diameter sections that can be adjusted to accommodate pipes of different diameters during driving. 9. A system for laying a trenchless tunnel that can use large pipe casings exceeding 72 inches in diameter for distance exceeding 100 feet to in the ground comprising: a. a high energy pile driving hammer that can deliver at least 40,000 foot pounds of driving force; b. means for providing a constant tension on said hammer and said an anvil to adjust to the recoil of said hammer when a pipe casing section is driven; c. a helmet sized in diameter to engage one end of a pipe section to be driven in conjunction with a plate and the other end of said helmet attached to said hammer; d. a tubular conduit that includes a knife-like forward edge for cutting through the earth sized in diameter to be attached to the first section of pipe casing to be driven for efficiently cutting through the earth; e. whereby said high energy hammer is used to drive successive sections of pipe casing attached together in conjunction with the cutting edge through the earth horizontally for distances exceeding 100 feet using pipe casings that exceed 72 inches in diameter. 10. A system for laying trenchless tunnels as in claim 9 including: f. means attached to said cutting head for distributing a lubricant on the outside of said pipe casing and on the inside of said pipe casing in accordance with a pre-determined arc lubrication distribution pattern on the outside of said pipe casing and on the inside of said pipe casing for reducing friction on the pipe casing during the hammer operation. 11. A system for laying trenchless tunnels as in claim 9 including: f. said helmet including a flanged conical end that includes a means for adjustably sizing the diameter of the helmet to accommodate different diameter pipes without requiring a separate individual helmet for each different size pipe casing diameter and including an internal channel for receiving said pile driving hammer portion to reduce the length of initial pit required to accommodate the pile driving hammer. -4468157, 19840800, Horton; US-4823719, 19890400, Sarwe; US-4907912, 19900300, Smith, 405/208; US-5609442, 19970300, Horton; US-5722797, 19980300, Horton, III; US-6024040, 20000200, Thomas; US-6092483, 20000700, Allen et al.; US-6196767, 20010300, Thomas, 405/203 tainer is disposed substantially within the thickness of the container holder; and rotating each of the plurality of containers such that each container rotates with respect to the container holder at a rotational velocity sufficient to create a mixture that comprises the first components, the second components, or the first and second components. 19. The method of claim 18, wherein the plurality of containers is simultaneously rotated. 20. The method of claim 18, wherein the rotating step comprises rotating the plurality of containers about an axis of rotation, wherein the axes of rotation of the containers are substantially parallel to one another.
