1. A method comprising:
- drilling and completing at least one well in an offshore field with a lead drilling and production vessel;
initiating production from the at least one well before formulating an initial plan for the development of the offshore field that identifies a number of wells to be drilled in the offshore field and a location of each of the wells to be drilled in the offshore field;
evaluating production from the at least one well after said step of initiating production;
selecting a secondary production vessel based upon the evaluated production from the at least one well; and
deploying the secondary production vessel to the offshore field so as to replace the lead drilling and production vessel and support production of the at least one well.

Abstract
Methods for developing an offshore field comprising deploying a lead drilling and production vessel to a offshore field to drill and complete at least one well. Production from the at least one well is initiated and evaluated. A secondary production vessel is selected based upon the evaluated production and is deployed to the offshore field to replace the lead drilling and production vessel and support production of the at least one well.

15. A method comprising:
-
drilling and completing a first well in an offshore field, wherein the first well is drilled and completed from a lead drilling and production vessel; producing the first well using the lead drilling and production vessel; evaluating production from the first well after said step of producing; using the evaluation of production from the first well to formulate an initial plan for the development of the offshore field, wherein the initial plan includes an identification of a number of wells to be drilled in the offshore field and a location of each of the wells to be drilled in the offshore field; and developing the offshore field utilizing a secondary production vessel selected in accordance with the initial plan for development of the offshore field. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A method comprising:
-
initiating production from a first well in an offshore field; formulating an initial plan for the development of the offshore field by evaluating the production from the first well after said step of initiating production, wherein the initial plan includes a selection of an export means to be employed at the offshore field; and developing the offshore field utilizing a modular production vessel having a configuration selected in accordance with the initial plan, wherein the configuration of the modular production vessel can change during the development of the offshore field. - View Dependent Claims (30, 31, 32, 33)
