2、Northchase Drive Houston, TX 77060 USA Foreword Foreword This Guide for Building and Classing Subchapter M Towing Vessels has been developed to clarify the requirements for classing existing and new towing vessels in service on major rivers and connecting intracoastal waterways, which are required t
3、o comply with 46 CFR Subchapter M, Inspection of Towing Vessels, Final Rule (Sub M), which was published in the U.S. Federal Register on June 20, 2016. The Guide provides supplemental and alternative requirements to the ABS Rules for Building and Classing Steel Vessels for Service on Rivers and Intr
4、acoastal Waterways (ABS River Rules) based on a comparison to Sub M. Requirements for equipment and arrangements regarding lifesaving, fire protection, machinery, piping, electrical, structure and stability are addressed. A vessel complying with the requirements contained in the River Rules and this
5、 Guide will comply with the design, construction, and outfitting requirements of Sub M and be eligible for Classification with ABS. This Guide becomes effective on the first day of the month of publication. Users are advised to check periodically on the ABS website www.eagle.org to verify that this

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.
