Abstract:
A movable self-elevating work platform, comprising:(a) a pair of buoyant hull components each of which: i) is capable of independent buoyant navigation over water; ii) has an elongated rectangular shape when viewed from above; and iii) has at least one leg slidably attached thereto, at least one of said hull components has at least 2 legs slidably attached thereto, said 2 legs disposed in a spaced apart relationship and substantially at either end of said hull, wherein until said pair of hulls are joined together, each of said hulls retains said elongated rectangular shape, each of said pair of buoyant hull components adapted so that one may be overlapped the other, and at least one coupling disposed between said pair of buoyant hull components when said pair of buoyant hull components are in a desired proximate and overlapping relationship, for coupling said buoyant hull components together to form a buoyant unitary work platform; and (b) a plurality of jacks attached to said unitary work platform and to each of said legs for raising and lowering said legs to the bed of a body of water upon which the unitary work platform is buoyantly disposed and for elevating and lowering said unitary work platform a desired distance above the surface of said body of water.
