Abstract
Method of managing hydrates in a subsea production system that includes a host production facility, one or more producers, one or more water injectors, a water injection line, and a single production line for directing production fluids from the producers to the host production facility. The method comprises placing a pig in the subsea production system, shutting in production from the producers, and injecting a displacement fluid into the subsea production system in order to displace production fluids in the production line. The method also includes applying electrically resistive heat along a selected portion of the single production line to maintain production fluids within the production line at a temperature above a hydrate formation temperature after production has been shut in.
