Abstract
Managing hydrates in a subsea includes a host production facility, a production cluster comprising one or more producers, a water injection cluster comprising one or more water injectors, a water injection line, and a single production line for directing production fluid from the one or more producers to the host production facility. The methods comprise 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 the hydrate inhibitor and any remaining production fluids in the production flowline and to further move the pig through the production flowline. The method may also include further injecting displacement fluid into the subsea production system in order to displace the hydrate inhibitor and pig through the single production line and to the host production facility.
