Abstract: With the implementation of CNOOC’s “peak carbon dioxide emissions and carbon neutrality” action plan and the shore power connection of Bohai oilfield groups,the energy-saving control transformation of high-energy-consuming systems on offshore platforms is particularly crucial. Taking the electric heat tracing system on offshore oil platforms as an example,this paper provides an overview of the current status of energy-saving development of electric heat tracing systems on offshore platforms. The structure,operation mode,and control strategy of the current heat tracing system on offshore platforms are elaborated. An energy-saving design scheme of heat tracing system power controlled by thyristor is proposed. The energy-saving effect and economy of this scheme during its trial on offshore platforms are analyzed,affirming its considerable social and economic benefits.

Key words: offshore oil platform, electric heat tracing, energy saving, economy
