Lift/Boarding Vessel

Abstract

In order to board a fixed structure, ocean conditions must be within a reasonable state that allows personnel to board in a safe manner. Due to the specific weather conditions, the boarding of fixed structures cannot be conducted. Both oil and gas and wind platforms must be boarded for maintenance and repair purposes. The invention allows boarding of fixed structures employing three buoyant vessels that can be adjusted to always be heading into the wind direction. Landing piles are pre-driven adjacent to the fixed structure and terminate at the ocean bottom. The invention has three deployable legs that extend through the buoyant vessel to the ocean bottom. The placement of the driven supports employs the same dimensions as the spacing of the vessel's extension legs. The vessel operator adjusts the heading of the three buoyant vessels to the wave heading. The legs are extended to the ocean bottom.

What is claimed is: 
     
         1 . A downhole drilling system for drilling micro-holes in earth formations comprising:
 a surface control unit which programs the action of the downhole tool and provides high-pressure fluid pressure to the downhole tool which in turn, by robotic action, parts the casing and drills a micro-hole to a general location, which is pre-programmed from the surface for the enhancement of oil and gas production.   a. A marine vessel which can provide a method to operate offshore in a harsh weather condition comprising of:   b. A vessel which provides a stable work platform without the effect of sea action.   c. A vessel which can control the vessel when in the sea action which allows only a heave action to be subjected to the vessel.   
     
     
         2 . To provide a method in which the vessel can be placed into operation without costly pre-loading. 
     
     
         3 . A vessel of  claim 1  which provides buoyant units which all fully operate to adjust the basic principles of the vessel employing the adjustment system which is controlled by the vessel captain. 
     
     
         4 . The vessel of  claim 1  to provide jacking legs which are mounted through the buoyant units and upon command, the captain can lift the vessel from the sea level. 
     
     
         5 . The vessel of  claim 1  allows the operation of the vessel when underway to operate as a standard marine vessel with respect to navigation, docking and other standard marine operation procedures. 
     
     
         6 . The vessel of  claim 1  provides a central prime mover service which provides power to the three buoyant, adjustable units. 
     
     
         7 . The invention is a marine vessel which can provide certain qualities which are used in the offshore operations in a harsh sea state allowing the vessel captain to depart a safe harbor traveling to the offshore location, adjusting the buoyant units to remain yawing of the vessel, providing only a heave action, docking the vessel onto pre-driven support units and lifting the vessel without pre-loading to the desired work height above the sea action providing a static platform to perform operations.
