Modular topsides system and method having dual installation capabilities for offshore structures
First Claim
1. A modular topsides for an offshore structure, comprising:
- a module support frame constructed separately from the offshore structure, comprising;
a plurality of frame members extending laterally and adapted to receive a plurality of production modules that can be loaded thereon;
a plurality of frame members extending uprightly and configured to form an upright framework to laterally restrain one or more of the production modules loaded therein;
at least one angular brace coupled between the frame members extending laterally and the frame members extending uprightly; and
a plurality of support interfaces coupled to the frame members and adapted to be coupled to the offshore structure after the offshore structure is installed at an installation site;
at least one production module coupled with the module support frame, the at least one production module being adapted to extract or process hydrocarbons from a hydrocarbon well in an offshore location; and
wherein the at least one production module includes a pocket formed in the module and is configured to be coupled to the module support frame with the at least one angular brace at least partially disposed within the pocket.

Abstract
The present disclosure provides an improved method and system for loading a topsides onto an offshore structure by functional modules. A module support frame forms a supporting structure to which production modules can be assembled. The production modules are adapted to extract or process hydrocarbons from a hydrocarbon well in an offshore location. One production module is a well bay production module to which other production modules can be coupled, including a drilling support production module, separation production module, export module, and utility module. The module support frame can be loaded onto floating barges and other modules assembled thereto to allow the barges to provide incremental and controlled support during the loading process and for the floatover installation. The barges can be floated out to the offshore structure and loaded onto the offshore structure by methods including a floatover method or with a heavy-lift crane vessel.

9. A method of installing a topsides to an offshore structure, comprising:
-
constructing a module support frame of a plurality of frame members extending laterally to receive a plurality of production modules loaded thereon and extending uprightly and configured to form an upright framework to laterally restrain one or more of the production modules loaded therein; bracing at least one of the frame members extending laterally with at least one of the frame members extending uprightly with an angular brace; loading the module support frame onto a transportation barge; coupling a first production module adapted to extract or process hydrocarbons from a hydrocarbon well in an offshore location to the module support frame to form a topsides, thereby installing a module with a pocket formed in the module and configured to be coupled to the module support frame with the angular brace at least partially disposed within the pocket; transporting the module support frame and the first production module to the offshore structure; installing the module support frame onto the offshore structure; and installing a second production module to the module support frame. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
