Added Value
|
The functionality and information, which
are provided by the INS, in addition to the requirements of the performance
standard for the individual equipment.
|
Alarm
|
An alarm is the highest priority of an
alert. Condition requiring immediate attention and action by the bridge team,
to maintain the safe navigation of the ship.
|
Alert
|
Alerts are announcing abnormal situations
and conditions requiring attention. Alerts are divided in three priorities:
alarms, warnings and cautions.
|
Alert announcements
|
Visual and acoustical presentation of
alerts.
|
Alert history list
|
Accessible list of past alerts.
|
Alert management
|
Concept for the harmonized regulation of
the monitoring, handling, distribution and presentation of alerts on the
bridge.
|
Automatic control functions
|
Functions that include automatic
heading, and/or track and/or speed control or other navigation related
automatic control functions.
|
Category A alerts
|
Alerts where graphical information at the
task station directly assigned to the function generating the alert is
necessary, as decision support for the evaluation the alert related condition.
|
Category B alerts
|
Alerts where no additional information
for decision support is necessary besides the information which can be
presented at the central alert management HMI.
|
Caution
|
Lowest priority of an alert. Awareness
of a condition which does not warrant a alarm or warning condition, but still
requires attention out of the ordinary consideration of the situation or of
given information.
|
Collision avoidance
|
The navigational task of detecting and
plotting other ships and objects to avoid collisions.
|
Consistent common reference system
(CCRS)
|
A sub-system or function of an INS for
acquisition, processing, storage, surveillance and distribution of data and
information providing identical and obligatory reference to sub-systems and
subsequent functions within an INS and to other connected equipment, if
available.
|
Consistent common reference point
(CCRP)
|
The Consistent Common Reference Point
(CCRP) is a location on own ship, to which all horizontal measurements such as
target range, bearing, relative course, relative speed, closest point of
approach (CPA) or time to closest point of approach (TCPA) are referenced,
typically the conning position of the bridge.
|
Degraded condition
|
Reduction in system functionality
resulting from failure.
|
Essential functions
|
Indispensable functions to be available
as required for the relevant operational use.
|
Essential information
|
Indispensable information to be
available as required for the relevant functions.
|
External safety related messages
|
Data received from outside of the ship
concerning the safety of navigation, through equipment listed in SOLAS chapter V and/or Maritime Safety Information messages.
|
Failure analysis
|
The logical, systematic examination of
an item, including its diagrams or formulas, to identify and analyse the
probability, causes and consequences of potential and real failures.
|
Human factor
|
Workload, capabilities and limits of a
user trained according to the regulations of the Organization.
|
Human machine interface (HMI)
|
The part of a system an operator
interacts with. The interface is the aggregate of means by which the users
interact with a machine, device, and system (the system). The interface
provides means for input, allowing the users to control the system and output,
allowing the system to inform the users.
|
Indication
|
Display of regular information and
conditions, not part of alert management.
|
Integrated navigation system
|
An INS is a composite navigation system
which performs at least the following tasks: collision avoidance, route
monitoring thus providing added value for the operator to plan, monitor and
safely navigate the progress of the ship. The INS allows meeting the respective
parts of SOLAS regulation V/19 and supports the proper application of
SOLAS regulation V/15.
|
Integrity
|
Ability of the INS to provide the user
with information within the specified accuracy in a timely, complete and
unambiguous manner, and alerts within a specified time when the system should
be used with caution or not at all.
|
Partial integrations
|
Smaller integrations which are not
covering the tasks “route monitoring” and “collision avoidance”.
|
Man-over-board mode (MOB)
|
Display mode for operations and actions
of a ship after a Man-over-board accident happened (release of safety
equipment, e.g., life buoy and life belt, performance of a return manoeuvre
etc.).
|
Multifunction display
|
A single visual display unit that can
present, either simultaneously or through a series of selectable pages,
information from more than a single function of an INS.
|
Mode awareness
|
The perception of the mariner regarding
the currently active Modes of Control, Operation and Display of the INS
including its subsystems, as supported by the presentations and indications at
an INS display or workstation.
|
Navigation control data
|
Task that provides information for the
manual and automatic control of the ship's movement on a task station.
|
One equipment concept
|
The equipment which is recognized as one
type of equipment by integrating the function of mandatory equipment of SOLAS
of a plural number.
|
Operational modes
|
Modes of operation depending on the sea
area.
|
Operational/functional
modules
|
Modules comprising the
operational/functional requirements for navigational systems.
|
Plausibility of data
|
The quality representing,
if data values are within the normal range for the respective type of data.
|
Route monitoring
|
The navigational task of
continuous surveillance of own ships position in relation to the pre-planned
route and the waters.
|
Safety related automatic
functions
|
Automatic functions that
directly impinge on hazards to ship or personnel, e.g., target tracking.
|
Search and rescue mode
|
Display mode for operations
of a ship involved in search and rescue actions.

more than one hard-key or soft-key action, excluding any necessary cursor
movements, or voice actuation using programmed codes.
|
Situation awareness
|
Situation awareness is the
mariners perception of the navigational and technical information provided, the
comprehension of their meaning and the projection of their status in the near
future, as required for timely reaction to the situation. Situation awareness
includes mode awareness.
|
