| 摘要 |
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.
