The adoption of this standard ANSI-B31.1 for pressure piping and power piping is subject to specific limitations or modifications as described in this part. Those requirements in ANSI-B31.1 which are not referred to in this part are adopted without change. Table 56.01-5(a) sets forth a general reference to various paragraphs in ANSI-B31.1 which are limited, modified, or replaced by regulations in this part. (a) This part contains requirements for the various ships' and barges' piping systems and appurtenances. (b) The respective piping systems installed on ships and barges shall have the necessary pumps, valves, regulation valves, safety valves, relief valves, flanges, fittings, pressure gages, liquid level indicators, thermometers, etc., for safe and efficient operation of the vessel. (c) Piping for industrial systems on mobile offshore drilling units need not fully comply with the requirements of [[Page 171]] this part but must meet Subpart 58.60 of this subchapter.
