Abstract

A novel insulation scheme has been developed by VerdErg Connectors Ltd to enshroud the pipeline and the flanges between subsea pipe sections to slow down the heat flow from the multiphase material to the surrounding water. The end-user of this insulation scheme required impartial validation of its thermal performance, so NPL embarked on a project to evaluate the system using a representative section of pipe by performing heating and cooling experiments while submerged in a deep loch in the Scottish Highlands. We describe the challenges of these measurements and present the thermal performance of the novel insulation.
