A system for conveying a fluid produced from at least one producing subsea well to an existing host facility via a flowline includes a support structure having at least a deck, a mooring system, and a plurality of topsides modules. The mooring system anchors the support structure to a seabed and passively positions the support structure proximate to the at least one producing subsea well. The support structure elevates the deck above a water's surface and is normally unmanned. The plurality of topsides modules are disposed on the deck. The topsides modules include at least: a power generation module; a switchgear module a flowline heating module; a chemical injection module; a water injection module; a subsea control module; and a control module that communicates with a remote command center.
