"Thermal VSM (Vertical Support Members) technology" with PCM(phase change material) and Heat Pipe proposed by Mr. Kim, Moo-Hong of PES. This technology can make the constant temperature and pressure in the ground exposed pipeline without additional electrical power supply. And I would like to provide the temperature and pressure value inside the pipeline by interfacing with the SCADA system.

VSM (vertical support members) : The principle of this system is to use the heat pipe filled with Phase Change Material (PCM) inside. In winter, this system will supply the warm temperature from the underground to the pipeline. And in summer, the temperature from the underground is used to prevent the pipeline from being heated more than necessary(Cooling by using underground temperature). This is a passive cooling geothermal system that keeps the temperature and pressure in the pipeline constant throughout the year without using any electric power. It is a kind of thermal circulation system which is useful and mandatory to the outdoor Oil/ Gas / Water pipeline. (Please see the following diagram and operation method in the figures)

By maintaining the temperature and pressure in the gas / oil pipeline constantly through this VSM equipment, gas and oil can be supplied stably without deterioration of transmission efficiency due to irregular pressure.

the pressure in pipeline is variable. (Algeria Site)
