15.12.3
Engine Generators. Engine generators by their inherent critical
nature must be protected from the elements by installation in an enclosed
room. Exhaust pipes, mufflers and standard weatherproof housings installed
outdoors will not provide satisfactory service life in a tropical environment.
15.13
Cathodic Protection. Provide cathodic protection for underground
ferrous pipelines and storage tanks and steel (sheet) piles. Cathodic
protection systems may be of the sacrificial anode, rectifier type or a
combination of the two. Locate rectifier control boxes in enclosed rooms or
within fiberglass enclosures with ventilation provisions where separate
dedicated rooms are not available. For connections to tanks and pipelines use
the exothermic weld types to prevent contact corrosion. When performing
calculations, use in-situ resistivity test results since ground resistivity in
the tropics varies from high (dry coral) to very low (volcanic clay).
