After field production data indicated that a recently installed insulated deepwater pipe-in-pipe (PIP) flowline with pressurized nitrogen gas in the annulus did not perform as designed, tests were conducted to investigate the thermal performance of the PIP. Pre-cast, half C-shell, rigid, open-cell polyurethane foam insulation was used in the PIP with the annulus filled with pressurized nitrogen gas. The thermal test results showed that extensive heat losses were due to the gaps in the insulation system, which exist because of the method of insulation application. This paper presents the numerical simulation results of the PIP heat transfer and the effects of gap sizes. Comparisons with test data are also presented.
