Shallow/intermediate water multipurpose floating platform for arctic environments
First Claim
1. A floating unit for conducting simultaneous drilling and production, comprising:
- a vessel having a bow end and a stern end, wherein the vessel includes at least two drilling derricks, at least two drilling modules, and at least one production module, all disposed on an upper surface thereof, such that the floating unit can simultaneously drill through use of the at least two drilling derricks and the at least two drilling modules, complete at least two wells while producing from a third well, and store the produced hydrocarbons, and wherein the bow end includes a hull which is strengthened for breaking ice;
at least two marine risers, wherein each marine riser depends from any one or more of the drilling or production modules and extends toward a water bottom;
a hydrocarbon production storage facility;
at least one production turret located on a lower surface of the vessel; and
at least one production riser depending from the production turret, toward a hydrocarbon bearing zone.

Abstract
A method and apparatus for conducting simultaneous drilling and production are provided. The apparatus can include a ship shape floating vessel, wherein the ship shape floating vessel includes at least two drilling derricks, at least two drilling modules, and at least one production module, all situated on the upper surface of the ship shape floating vessel. The drilling modules are adapted for conducting drilling operations; the production module is adapted for conducting production operations. The apparatus can include at least two marine risers, wherein each marine riser depends from a drilling or production module toward a hydrocarbon bearing zone or sea floor and is adapted for conducting drilling and/or production operations; at least one production turret located on the lower surface of the ship shape floating vessel; and at least one production riser, wherein the production riser depends from the production turret, extends toward the sea floor, and is adapted for conducting production operations.

10. A floating unit for use in extended operations as a drilling, production, storage and offloading platform, comprising:
-
a ship shape floating vessel having a stern end and a bow end, wherein the bow end includes a hull which is strengthened for breaking ice; two drilling derricks, two drilling modules, and a production module all situated on the upper surface of the ship shape floating vessel such that the floating unit can simultaneously drill through use of the at least two drilling derricks and the at least two drilling modules, complete at least two wells while producing from a third well, and store the produced hydrocarbons, wherein the drilling modules are for conducting drilling operations, wherein the production module is for conducting production operations; two marine risers each depending from a single drilling or production module and extending from a single drilling derrick, wherein the marine risers are for conducting drilling and production operations; a first thruster located at the stern end and a second thruster located at the bow end of the ship shape floating vessel; a main thruster located at the stern end of the ship shape floating vessel; a production turret, including a production riser, located on the bottom surface of the ship shape floating vessel; a vent stack and a crane each located on the upper surface of the ship shape floating vessel; and a hydrocarbon production storage facility located within the ship shape floating vessel. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
