11. A method, comprising:
providing a lower platform block adjacent to a sea floor including a first frame, a plurality of docking assemblies connected to the first frame, and a plurality of first conductor tubes connected to the first frame;
releasably coupling at least a first jacket connector block including a second frame and a plurality of second conductor tubes connected to the second frame to the lower platform block,
wherein releasably coupling the at least a first jacket connector block to the lower platform block comprises aligning the second conductor tubes with the first conductor tubes via a first plurality of removable guides removably coupled within a first interior of the plurality of second conductor tubes, wherein aligning the second conductor tubes with the first conductor tubes further comprises mating one removable guide of the first plurality of removable guides that is longer than the remaining removable guides of the first plurality of removable guides first with the first conductor tubes to provide an initial alignment and allow subsequent mating with the remaining removable guides of the first plurality of removable guides;
connecting a first accessory line connected to and extending axially a length of one conductor tube of the plurality of first conductor tubes to a second accessory line connected to and extending axially a length of one conductor tube of the plurality of second conductor tubes;
releasably coupling a platform deck block above a sea level including a third frame defining a deck and a plurality of third conductor tubes connected to the third frame to the first jacket connector,
wherein releasably coupling the platform deck block to the first jacket connector comprises aligning the third conductor tubes with the second conductor tubes via a second plurality of removable guides removably coupled within a second interior of the plurality of third conductor tubes, wherein aligning the third conductor tubes with the second conductor tubes further comprises mating one removable guide of the second plurality of removable guides that is longer than the remaining removable guides of the second plurality of removable guides first with the second conductor tubes to provide an initial alignment and allow subsequent mating with the remaining removable guides of the second plurality of removable guides; and
connecting the second accessory line to a third accessory line connected to and extending axially a length of one conductor tube of the plurality of third conductor tubes;
wherein the first, second, and third conductor tubes define conductor tubes from the lower platform block to the platform deck block.
