7、tems since 2015. Requirements for ambient pressure submersibles have been added. Sections 1 through 10 provide the general requirements that are applicable to all categories of underwater vehicles, systems and hyperbaric facilities. Section 11 provides the specific requirements that are applicable t

8、o manned submersibles. Section 12 provides the specific requirements that are applicable to lock-out submersibles. Section 13 provides the specific requirements that are applicable to ambient pressure submersibles. Section 14 provides the specific requirements that are applicable to diving systems.

9、Section 15 provides the specific requirements that are applicable to atmospheric diving suits. Section 16 provides the specific requirements that are applicable to remotely operated vehicles. Section 17 provides the specific requirements that are applicable to autonomous underwater vehicles. Section

10、 18 provides the specific requirements that are applicable to handling systems. Section 19 provides the specific requirements that are applicable to dive control stations. Section 20 provides the requirements for surveys after construction. Appendix 1 provides relevant excerpts from IMO Res. A.831 (

12、s 1 January of the year shown. Note Regarding the Changes to Section 1 (1 January 2008) In 2008, Section 1, “Conditions of Classification” was consolidated into a generic booklet, entitled Rules for Conditions of Classification (Part 1) for all vessels other than those in offshore service. The purpo

13、se of this consolidation was to emphasize the common applicability of the classification requirements in “Section 1” to ABS-classed vessels, other marine structures and their associated machinery, and thereby make “Conditions of Classification” more readily a common Rule of the various ABS Rules and

14、 Guides, as appropriate. Thus, Section 1 of these Rules specifies only the unique requirements applicable to underwater vehicles, systems and hyperbaric facilities. These supplemental requirements are always to be used with the aforementioned Rules for Conditions of Classification (Part 1). ABSRULES
