Abstract:  Nowadays, normal electric heating tracing in offshore oil engineering cannot provide high power and adapt to extreme hostile working conditions. Mineral insulated (MI) electric heat tracing shows its good performance confronting -40℃ extremely low temperature and high corrosive working condition in Nexen Oil Project. It provides a new idea for electrical heating tracing in offshore oil engineering which requires providing high power and resisting extreme hostile working condition. We study the feasibility of application of MI electric heat tracing in offshore oil engineering and introduce the typical characteristics including main products, working principle, application areas, selection of design, and installation and application.
