Foreword
The 2014 edition of the Rules for Building and Classing Underwater Vehicles, Systems and Hyperbaric
Facilities incorporates all Rule Changes and Corrigenda items since 2012. Requirements for atmospheric
diving suits and autonomous underwater vehicles are added. The requirements for remotely operated vehicleshave been updated Also, some requirements have been revised for clarity and others to more accurately
reflect actual practice.
• Sections 1 through 10 provide the general requirements that are applicable to all categories of underwatervehicles, systems and hyperbaric facilities.
• Section 11 provides the specific requirements that are applicable to 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 diving systems.
• Section 14 provides the specific requirements that are applicable to atmospheric diving suits.
• Section 15 provides the specific requirements that are applicable to remotely operated vehicles.• Section 16 provides the specific requirements that are applicable to autonomous underwater vehicles.
• Section 17 provides the specific requirements that are applicable to handling systems.
• Section 18 provides the specific requirements that are applicable to dive control stations.
• Section 19 provides the requirements for surveys after construction.
• Appendix 1 provides relevant excerpts from IMO Res. A.831 (19) Code of Safety for Diving Systemsregarding diving bell emergency locating devices
The effective date of each technical change is shown in parentheses at the end of the subsection/paragraph
titles within the text of each Section. Unless a particular date and month are shown, the effective date is
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 purpose 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 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 theaforementioned Rules for Conditions of Classification (Part 1).

S e c t i o n 1 : S c o p e a n d C o n d i t i o n s o f C l a s s i f i c a t i o n
S E C T I O N 1 Scope and Conditions of Classification
1 Classification (1 January 2008)
The requirements for conditions of classification are contained in the separate, generic ABS Rules forConditions of Classification (Part 1).
Additional requirements specific to underwater vehicles, systems, and hyperbaric facilities are contained inthe following portions of this Section.
3 Classification Symbols and Notations (1 January 2008)
A listing of Classification Symbols and Notations available to the Owners of vessels, offshore drilling and production units and other marine structures and systems, “List of ABS Notations and Symbols” is availablefrom the ABS website “http://www.eagle.org”.
The following notations are specific to underwater vehicles, systems and hyperbaric facilities.
3.1 Classed Units (2012)
Manned or occasionally manned underwater vehicles, underwater facilities, hyperbaric facilities, anddiving simulators which have been built to the satisfaction of the ABS Surveyors to the full requirements
of these Rules, or their equivalent, where approved by the Committee for the service will be classed and
distinguished in the Record by the symbols A1 followed by the appropriate notation, such as Submersible,Passenger Submersible, Lock-Out Submersible, Remotely Operated Vehicle, Habitat, etc.
3.3 Classed Systems (2012)
In addition to the Classification of the individual underwater vehicles, underwater facilities, and hyperbaric
facilities mentioned in 1/3.1, a system may be classed and distinguished in the Record by the symbols A1 followed by the appropriate notation, such as Air Div ing System (P) or (F), Mixed Gas Diving System(P) or (F), Saturation Diving System (P) or (F) (See Subsection 13/3), Underwater Complex, etc., provided the system has been built to the satisfaction of the ABS Surveyors to the full requirements of
these Rules, or their equivalent.
3.4 Support Components for Classed Systems (2012)
Support components for classed systems include pressure vessels for human occupancy (surface compression
chambers, diving bells, hyperbaric evacuation units, etc.), handling systems and dive control stations.
Support components that have been built under the supervision of the ABS Surveyors to the full requirementsof these Rules, or their equivalent, may be certified by ABS and issued Underwater System Support
Component Certificates (ABS-USC-1) with the symbol followed by the appropriate notation, such asDiving Bell, Handling System, Dive Control Station , etc.
Support components certified under the provisions of these Rules, whose surveys are maintained current,
are eligible for use in a classed system.
3.5 New and Existing Underwater Units, Systems or Support Components Not Built UnderSurvey (2012)
Units, systems or support components not built under ABS survey but for which classification or certification
(as applicable) is requested at a later date, will require submittal of available drawings and/or documentation
as listed in Subsections 1/7 and 1/9 in conjunction with the following:

22/200
Section 1 Scope and Conditions of Classification
2 ABS RULES FOR BUILDING AND CLASSING UNDERWATER VEHICLES, SYSTEMS AND HYPERBARIC FACILITIES . 2014
i) Welding procedures (WPS) and performance qualifications records (PQR)
ii) NDT records
iii) Material mill test reports
iv) All other certificates of past surveys and tests results conducted by the original certifying agency,
insofar as such documentation is available and valid
v) Written test procedures for the tests and trials required to be performed for classification orcertification
New and existing pressure hulls and pressure vessels for human occupancy and acrylic windows will only
be accepted if proof of fabrication under survey by an IACS member Classification Society or recognizedFlag Administration is provided.
Additionally, the units, systems or support components will be subject to special periodical surveys, hydrostatic
and functional tests.
Where found satisfactory and thereafter approved by the Committee, the underwater unit or system will be
classed and distinguished in the Record by the appropriate symbols and notations as described in 1/3.1 and
1/3.3, but the mark signifying the survey during construction will be omitted.
Where found satisfactory, the support component will be issued an Underwater System Support Component
Certificate (ABS-USC-1) with the appropriate notations, but the symbol as described in 1/3.4 signifyingsurvey during construction will be omitted.
3.7 Other Conditions
