ABS GUIDE FOR BUILDING AND CLASSING INTERNATIONAL NAVAL SHIPS . 2022 ii
Notices and General Information

Introduction
1. The year 2022 edition of the Guide for Building and Classing International Naval Ships consists
of the Parts shown in Table 1. Content has been added as necessary to extend its applicability to
military vessels and other Government owned vessels in non-commercial service. The following
is provided for information regarding each Part:
a) Part 1: The purpose of the generic title ABS Rules for Conditions of Classification (Part 1)
is to reflect the expanded contents of PART 1, as a result of including consolidated
requirements for “Classification” applicable to all types of and sizes of vessels, barges and
specific shipboard arrangements/systems, etc., except for those in offshore service, as
specified in the Foreword to Part 1. Additional specific requirements are contained in
Chapter 11 of Part 1.
b) Part 2: The purpose of the generic title ABS Rules for Materials and Welding (Part 2) is to
reflect the common applicability of the requirements to all ABS-classed vessels, other
marine structures and their associated machinery, and thereby make PART 2 more readily
a common “PART” of various ABS Rules and Guides, as appropriate.
c) Part 3: The ABS Guide for Building and Classing International Naval Ships (Part 3) is
based upon other existing ABS Rules and Guides to inherently incorporate baseline standards
for hull design, construction, safety and environmental protection expected of all
commercial vessels worldwide.
d) Part 4: The ABS Guide for Building and Classing International Naval Ships (Part 4) is
based upon other existing ABS Rules and Guides to inherently incorporate baseline standards
for machinery design, construction, safety and environmental protection expected of all
commercial vessels worldwide.
e) Part 5: The ABS Rules for Building and Classing Marine Vessels (Part 5A, 5B, 5C)
contains structural requirements for specific vessel types (tankers, bulk carriers, container
carriers, liquefied gas carriers, passenger carriers, chemical carriers, and vessels intended
to carry vehicles) that are normally classed in accordance with ABS Rules for Building
and Classing Marine Vessels. The inclusion of this existing Part 5 in the ABS Guide for
Building and Classing International Naval Ships is mainly for its potential application to
certain naval ships (e.g., Oilers) and will require special consideration when applying its
requirements since they were intended for application to commercial vessels and are
therefore based heavily upon SOLAS and other IMO Convention standards; no
modifications have been made to it at this time to tailor its applicability to military vessels
or other Government-owned vessels in non-commercial service.
f) Part 6: The ABS Guide for Building and Classing International Naval Ships (Part 6)
provides requirements regarding those optional notations offered by ABS that are most
frequently requested and/or considered to be most applicable or unique to military vessels
and other Government owned vessels in non-commercial service. A complete listing of
available optional notations is on the ABS website (www.eagle.org). The requirements in
Part 6 apply in addition to the basic requirements for Classification, but only apply for
those optional notations that are requested.
g) Part 6: The ABS Guide for Building and Classing International Naval Ships (Part 6)
provides requirements regarding those optional notations offered by ABS that are most
frequently requested and/or considered to be most applicable or unique to military vessels
and other Government owned vessels in non-commercial service. A complete listing of
available optional notations is on the ABS website (www.eagle.org). The requirements in
Part 6 apply in addition to the basic requirements for Classification, but only apply for
those optional notations that are requested.

h) Part 7: The purpose of the generic title ABS Rules for Survey After Construction (Part 7)
is to reflect the common applicability of survey requirements to all ABS-classed vessels,
other marine structures and their associated machinery.
2. The numbering system applied in the Guide is shown in Table 2.
3. The primary changes from the January 2022 Guide are identified and listed in Table 3. The
effective date of the indicated Rule Changes is 1 July 2022, unless specifically indicated otherwise.
4. The effective date of each technical change since 1993 is shown in parenthesis at the end of the
subsection/paragraph titles within the text of each Part. Unless a particular date and month are
shown, the years in parentheses refer to the following effective dates:

(2000) and after 1 January 2000 (and subsequent years) (1996) 9 May 1996
(1999) 12 May 1999 (1995) 15 May 1995
(1998) 13 May 1998 (1994) 9 May 1994
(1997) 19 May 1997 (1993) 11 May 1993

For certain changes that have a major impact on shipyards, designers and vendors, ABS has
instituted a two-year Rule cycle to give the industry more time to prepare for these changes. The
text of these changes will appear in a box along with the effective date just under the existing
requirement.

Definition of Terms Used Throughout the Guide

Naval Vessel: This term is used to broadly refer to Government owned vessels in non-commercial service;
primarily vessels whose purpose is for safety, security and/or defense. As such, it applies to vessels of the
Navy, the Coast Guard, or other Government agency of a country; the main differences from commercial
vessels being: (1) such vessels are not required by law to comply with national or international codes or
standards with which commercial vessels must comply, and (2) in many cases such vessels are equipped and
outfitted for combat or related military missions which requires vessel systems, functions, and capabilities
to address operational scenarios not encountered by commercial vessels.
The criteria in this Guide was developed around the following features/characteristics/assumptions with regard
to the vessels to which this Guide applies: surface vessels, non-nuclear, welded steel construction, welded
aluminum construction, areas of composite structure (other than primary structure), mono-hull, displacement
type (however, the Guide does address dynamically supported vessels), no restrictions on length, IMO/SOLAS
not mandatory (if invoked in whole or in part it is invoked by choice/policy of the Naval Administration),
unrestricted service (but criteria is included to allow for lesser service routes), fitted with systems that
support aircraft operations, combat operations, or other military-unique missions.
Naval Administration: The department, directorate, bureau or command to whom the National Government
has delegated authority over the acquisition, acceptance, maintenance and technical requirements of naval
vessels, and who acts on the Government’s behalf in all matters relating to the procurement and support of
the vessels. In the case where these authorities are invested in separate departments within the naval
organization, the term “Naval Administration” means the ensemble of departments having those authorities,
or the command that overarches these departments.

Notices and General Information

Special Consideration: Where the term “special consideration” is used in this Guide, it is intended to indicate
that ABS will consider a particular specified arrangement, detail, or proposed alternative or equivalency, or that
application of the criteria in the Guide may require modification from what is prescribed in order to satisfy the
intent of the requirements. Arrangements, details and proposed alternatives or equivalency determinations that
require special consideration for ABS classification will be reviewed in conjunction with submitted
calculations and other supporting documentation in accordance with sound engineering practice.
Recognized Standard: A document developed and maintained by an organization whose functions include
the development and maintenance of specifications and standards, and designated as applicable for use in
marine applications or made suitable by the addition of supplemental criteria. Acceptance of a recognized
standard and any required supplemental criteria are subject to review and approval by ABS.
HM&E System: Hull, mechanical and electrical (HM&E) systems are those systems relating to the safety
of vessel and crew in the basic operation and navigation of the vessel (i.e., aspects of the platform other than
mission systems and mission-related or military-unique aspects that are the domain of other designated
authorities).
Mission System: The systems, subsystems and individual equipment directly dedicated to carrying out the
mission of the ship as opposed to those systems needed for crew and vessel safety regarding basic operation
and navigation of the vessel. Mission systems include combat systems (weapons and sensors), C4ISR
systems (including information security), and those systems and features related to military-unique aspects
that are required for operation in a military environment (aspects such as signatures, shock, survivability,
weapons effects, etc.).
