T/CPCIF 0179-2022 Electrical Equipment Design Code for Dangerous Environment in Offshore and Marine Explosion-prone Areas

Scope

Scope: This document specifies the environmental conditions and parameter levels for the installation of electrical equipment in offshore and marine explosive gas environments, the requirements for hazardous areas and explosion-proof technology, and the selection and installation of equipment. This document applies to explosion-proof electrical equipment used in offshore and marine facilities in the oil and gas industry, such as fixed offshore facilities, mobile offshore facilities, artificial islands, and onshore production, storage, transportation, and reception facilities. This document does not apply to explosion-proof electrical equipment installed in explosive gas environments on land. This document does not apply to explosion-proof electrical equipment installed in explosive dust environments offshore and at sea.
