Requirements for ambient pressure sub

12、mersibles 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 to manned submersibles. Section 12 provides the specifi

13、c 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. Section 15 provides the specific requirements that are

14、 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 18 provides the specific requirements that are applic

15、able 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 (19) Code of Safety for Diving Systems regarding diving

17、ges 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 purpose of this consolidation was to emphasize the common a

18、pplicability 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 Guides, as appropriate. Thus, Section 1 of these Rule

19、s 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 FOR BUILDING AND CLASSING UNDERWATER VEHICLES, SYSTEM
