Abstract: A jack up work platform is recited. The work platform comprises a hovercraft vessel outfitted with several jack up legs. The hovercraft can traverse environmentally sensitive terrain such a brackish and freshwater marshes without the need to dig canals that may cause or exacerbate salt water intrusion. Once the drilling or exploration site is reached, the jack up legs may be lowered, lifting the work platform above the surface. Once the vessel is secured on the legs, it may be used like a conventional oil field work platform for drilling, exploration, or construction jobs for which other work platforms or vessels are typically used. The deck of the hovercraft may serve as the work platform or the deck may be provided with a cantilevered work platform extension. The hovercraft will preferably be provided with typical oil field heavy machinery such as a crane for assembly of the legs, and drill stem as well as for work on other structures.
