No automation
the full-time performance by the human
boatmaster of all aspects of the dynamic
navigation tasks, even when enhanced by
warning or intervention systems
Example: navigation with the support of the
radar installation
Steering assistance
the context-specific performance by a steering
automation system using certain information
about the navigational environment and with the
expectation that the human boatmaster performs
all remaining aspects of the dynamic navigation
tasks
Examples : rate-of-turn regulator ; track pilot
(track-keeping system for inland vessels along
pre-defined guiding lines)
Partial automation
the context-specific performance by a
navigation automation system of both steering
and propulsion using certain information about
the navigational environment and with the
expectation that the human boatmaster
performs all remaining aspects of the dynamic
navigation tasks

8.1 OBJECTIVE
The objective of this Chapter is to provide a process to ensure that the design, manufacture, through
life survey, maintenance and disposal requirements of MASS are appropriately considered. This
Chapter is written as a goal based requirement to permit the maximum scope to introduce innovative
ideas into the design.
8.2 SCOPE
8.2.1 The scope of this Chapter is to cover the design, manufacture and through life survey, maintenance and disposal
requirements of MASS. The MASS in this context is taken as the vessel, equipment and systems (including
software), afloat and ashore, which constitute all the key elements of the MASS.
8.2.2 The MASS should be designed, constructed and maintained with reasonable care and, in particular, in compliance
with the requirements of a classification society which is recognised by the Flag State Administration; or in
accordance with applicable national standards of the Flag Administration which provide an equivalent level of
safety, for example UK MCA Workboat Code.
System performs the entire dynamic navigation tasks
(when engaged)

Conditional automation
the sustained context-specific performance by
a navigation automation system of all dynamic
navigation tasks, including collision avoidance,
with the expectation that the human boatmaster
will be receptive to requests to intervene and to
system failures and will respond appropriately
High automation
the sustained context-specific performance by
a navigation automation system of all dynamic
navigation tasks and fall-back operation, without
expecting a human boatmaster responding to a
request to intervene 1
Example : Vessel operating on a canal section
between two successive locks (environment
well known), but the automation system is not
able to manage alone the passage through the
lock (requiring human intervention)
Subject to

execution,
remote
control is

(vessel

monitoring
of and
response to
the environment
or
fall-back
performance).
It may have
an influence
on the number
or qualification
of crews
8.2.3 For the defined operational life of the MASS it should be designed and constructed to:
n Enable the MASS to operate in all Reasonably Foreseeable Operating Conditions (RFOC);
n Carry and respond to all foreseen loads in a predictable manner, with a level of integrity commensurate with
operational and safety requirements;
n Ensure the watertight and weathertight integrity, to meet buoyancy and stability requirements;
n Minimise the risk of initiating fire and explosion;
n Minimise the spread of fire;
n Enable the maintenance and repair in accordance with the maintenance philosophy.
8.2.4 Operators should be provided with adequate access, information and instructions for the safe operation and
maintenance of the MASS.
8.3 SELECTION OF DESIGN BUILD AND SURVEY REQUIREMENTS
5
Autonomous = Full automation
the sustained and unconditional performance by
a navigation automation system of all dynamic
navigation tasks and fall-back operation, without
expecting a human boatmaster will respond to
a request to intervene
8.3.1 MASS shall be certified to demonstrate compliance with the requirements of the Code. Certification requirements
are covered in Chapter 13.
8.3.2 The MASS supplier is to provide evidence and justification to the RO (or MCA approved Certifying Authority for
Workboats) to demonstrate that the MASS is fit for the intended role and meets the goals of this Chapter. This
evidence is to include the following information:

This level introduces two different functionalities: the ability of “normal” operation without expecting human intervention and the
exhaustive fall-back. Two sub-levels could be envisaged.
