Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or

Introduction
Ships have more and more equipment with updateable software on-board. Current requirements
for on-board use of computer-based systems require a software registry for such equipment (IACS
URE22rev2), but these registries are not defined, can be difficult to understand and use, and are often
not updated. This is partly caused by the increasing quantity of computer equipment and applicable
regulations creating additional work for crew, shipping companies and other stakeholders. This
situation makes staying current on software updates more difficult, which also introduces increased
risks of equipment problems. This document began its development based on a 2017 CIRM-BIMCO
industry standard for software maintenance procedures.
This document defines a ship software logging system (SSLS) for shipboard equipment software.
Recognizing that maintenance of shipboard software is a major undertaking, this first edition initially
sets base characteristics. The SSLS can be used by various users and log data from various types of
equipment. It is expected that this document will evolve over time together with related regulations
and as experience on the use of the introduced concept accumulates.
This document considers the following:
— cyber risk management is incorporated into the design and use of the SSLS;
— equipment messages pass from the equipment to the SSLS automatically when possible;
— the equipment sends standard version messages with software version information on appropriate
time intervals.
INTERNATIONAL STANDARD ISO 24060:2021(E)
Ships and marine technology — Ship software logging
system for operational technology
1 Scope
This document defines a ship software logging system (SSLS) for logging and retrieving software
version information and current operational status. The system facilitates software maintenance for
ship operational technology equipment and associated integrated systems, including but not limited to:
— control and alarm systems;
— fire and water mist systems;
— navigation and communication systems;
— steering control systems;
— propulsion systems;
— power generation systems;
— performance monitoring systems;
— auxiliary systems.
This document sets requirements for the design and usability of a ship software logging system (SSLS)
software that:
— records software versions for equipment with updateable software (hereinafter “equipment”);
— sets an initial log entry when equipment is first installed or detected by the SSLS;
— includes a repository of electronic service reports associated with log entries;
— automatically logs reports sent by the equipment.

4 Technology design
4.1 Updateable equipment inventory
4.1.1 General
For any given ship, an SSLS shall apply to any on board equipment that contains software which can
be updated. An inventory of equipment should have the ability to be automatically generated from
connected equipment, or manually entered. Some targeted systems for the SSLS to track include, for
example, control and alarm systems; fire and water mist systems; navigation and communication
systems; steering control systems; propulsion systems; power generation systems; performance
monitoring systems; and auxiliary systems.
4.1.2 Equipment details
Where equipment as listed in 4.1.1 has been identified, the SSLS shall enable an initial log entry
containing the following equipment details for each piece of equipment:
a) device type;
b) manufacturer;
c) unique identifier, which is any specific equipment identifier;
d) serial number;
e) manufacture date;
f) model number, which can be a model code set by a manufacturer;
g) date and time of log entry;
h) software version.
NOTE This log entry can be setup automatically from the first version message received from connected
equipment or en
