36、equirements In general, vessels are to comply with the requirements contained in the ABS River Rules and this Guide to receive the notations listed in Subsection 1/1. Various requirements from Sub M are considered to be outside the scope of, and therefore supplemental to, the ABS River Rules. These

37、supplemental requirements are summarized in Section 2, Table 1 through Section 2, Table 4 for Lifesaving, Fire Protection, Machinery and Electrical Systems and Equipment, and Construction and Arrangement, respectively. The “Existing Vessel” and “New Vessel” columns indicate whether such vessels, as

38、defined by 1/7.3 and 1/7.5, respectively, are to comply with specific provisions. The provisions listed in the “Supplemental Requirements” column are not exhaustive; each original rule and regulation is applicable as written in its original form, with conditions, summaries and clarifications listed

39、herein for guidance. Certain sections of Sub M that are considered administrative, operational, or less stringent than corresponding ABS River Rules have not been listed.
