HAC for Jetty

[Namdam]

Hi, I'm an electrical engineering student working on a project to prepare the hazardous area classification for a jetty over the ocean which is approximately 80 feet from well-maintained pipelines carrying fuel oil. I am required to specify the classification for the electrical equipment (lights, electrical panels, cables, conduit, receptacles, etc.) that will be installed on the jetty.

Can you refer me to a standard which can be used in preparing a HAC drawing for this application? The API RP 500 does not seem to cover jetties.

Thank you.

Since this appears to be a class assignment, I’d first refer your research to NEC Section 500.4(B).

I will tell you that API RP 500 and NFPA 497 are both quite sufficient to classify a location “…which is approximately 80 feet from well-maintained pipelines carrying fuel oil.” (A specific reference to a “jetty” is a red herring to a more general solution)

You may find some additional conceptual help in Article 515, specifically Figure 515.3 and NFPA 30.

BTW Welcome and it's encouraging to see Electrical Area Classification taught in a school.
