A buoyantly moveable, self-elevating (jack-up) artificial work island or platform self-assembled while floating upon a work body of water by reversibly coupling together a plurality of independently buoyant modular hull components ( ), each of which is relatively narrow beam and capable of navigation through relatively narrow waterways. After self-assembly, the work platform is self-elevating upon a plurality of legs ( ) to a desired distance above the work body of water. The work platform may be buoyantly moved to subsequent work locations as a unit, or separated into modular hull components each of which may be buoyantly moved separately to the subsequent locations. The work platform may further have a drilling derrick, a hoist, drilling fluid pumps, a rotary table and other equipment associated with earthboring for oil and gas installed thereon. The work platform may be elevated above the water surface a sufficient distance to accomodate operational conditions. In one embodiment, additional internal pilings are driven through the legs into the water bottom to provide additional support.

A buoyantly moveable, self-elevating (jack-up) artificial work island economically and quickly self-assembled while floating upon work body of water by reversibly coupling together a plurality of independently buoyant modular hull components each of which is of relatively narrow beam and therefore capable of navigation though relatively narrow water-ways. After self-assembly said artificial work island is self-elevating upon a plurality of legs a desired distance above said work body of water. The island may be buoyantly moved to subsequent work locations as a unit or separated into modular hull components each of which may be buoyantly moved separately to the subsequent locations. The island may have a drilling derrick, a hoist, drilling fluid pumps, a rotary table and other equipment associated with earthboring for oil and gas installed thereon.

An apparatus for reducing the draft and increasing the load bearing area and stability of a Marine drilling barge may be temporarily or permanently mounted to the barge. The apparatus includes twin parallel hulls separated by and connected to a tension resistant truss, a support frame mounted to the twin parallel hulls, compression resistant members connected to the support frame that span between the parallel hulls, and pumps to remove water ballast from the hulls so that the apparatus can be raised and lowered in the water. The apparatus is submerged, the barge to be modified is then situated between the submerged apparatus hulls, the ballast is then removed from the submerged hulls to emerge the apparatus and lift the barge. When connected to the barge the apparatus provides a reduction in barge draft. The apparatus and barge may then be moved in combination and submerged together as a single unit.
