Abstract

Pipe loop (1) for continuous transport of hydrocarbons from a subsea installation, without flow disturbances while undertaking pigging or fluid control operations, which pipe loop is comprising a first pipe section (2) that is connecting an onshore plant, a surface platform or another installation to at least one T-coupling (3) that is connected to receive said hydrocarbons from the subsea installation, and a second pipe section (4) that is providing connection from said T-coupling back to the onshore plant, surface platform or another installation. The pipe loop is distinguished in that the first pipe section (2) has inner diameter d and is arranged for transport from the onshore plant, surface platform or another installation of glycol, chemicals, additional mediums for fluid control, pigs and optional hydrocarbon liquid, to said T-coupling; and the second pipe section (4) has inner diameter D and is arranged for transport of fluid from both the subsea installation and the first pipe section, and pigs, from said T-coupling back to the onshore plant, surface platform or another installation; wherein d ≤D, with the additional proviso that the difference between said diameters is sufficiently small for a pig to be passed out through the first pipe section, through said T-coupling and back through the second pipe section. Method with use of pipe loop, for quenching a hydrocarbon stream.
