1. A method comprising:
- deploying a lead drilling and production vessel to a offshore field;
drilling and completing at least one well in the offshore field;
initiating production from the at least one well;
evaluating production from the at least one well;
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.
