The ARCMASTER™ has been designed by HMT to significantly reduce the likelihood of a rim fire caused by a lightning strike. This Submerged Grounding System provides multiple conduction paths for lightning induced electrical charges to be transmitted from the external floating roof to the tank shell and subsequently to the ground. The ARCMASTER™ was designed by HMT under the guidance of the recommendations of the API RP 545.
If you would like to significantly reduce the likelihood of such a lightning induced rim fire, choose the HMT ARCMASTER™ Submerged Grounding System.
