CODE FOR THE SAFETY OF HIGH SPEED CRAFT (HSC CODE) Resolution
MSC.36(63) 1994 as amended by Resolution MSC.119(74) 2001)
SHIPBORNE NAVIGATIONAL SYSTEMS AND EQUIPMENT AND VOYAGE DATA RECORDER
chapter covers equipment which relates to the navigation of
the craft as distinct from the safe functioning of the craft.
The following paragraphs represent the minimum requirements
for normal safe navigation unless it is demonstrated to the
Administration that an equivalent level of safety is achieved
by other means.
The equipment and its installation should be to the satisfaction
of the Administration.
The Administration should determine to what extent the provisions
of this chapter do not apply to craft below 150 gross tonnage.
Craft should be provided with a magnetic compass which is capable
of operating without electrical supply, and which may be used
for steering purposes. This compass should be mounted in a suitable
binnacle containing the required correcting devices and should
be suitable for the speed and motion characteristics of the
The compass card or repeater should be capable of being easily
read from the position at which the craft is normally controlled.
Each magnetic compass should be properly adjusted and its table
or curve of residual deviations should be available at all times.
Care should be taken in siting a magnetic compass or magnetic
sensing element so that magnetic interference is eliminated
or minimized as far as is practicable.
Passenger craft certified to carry 100 passengers or less should,
in addition to the compass required by 13.2.1, be provided with
an instrument, suitable for the speed and motion characteristics
and area of operation of the craft, providing a heading reference
of accuracy superior to that provided by a magnetic compass.
Cargo craft and passenger craft certified to carry more than
100 passengers should, in addition to the compass required in
13.2.1, be provided with a gyro-compass which should be suitable
for the speed and motion characteristics and area of operation
of the craft.
Speed and distance measurement
should be provided with a device to measure speed and distance,
except when no device is available which will function reliably
at all speeds at which the craft may operate.
and distance-measuring devices on craft fitted with an automatic
radar plotting aid should be capable of measuring speed and
distance through the water.
craft should be fitted with an echo-sounding device which will
give an indication of depth of water to a sufficient degree
of accuracy for use when the craft is in the displacement mode.
Craft should be provided with at least one azimuth-stablized
radar operating in the X band (3 cm).
of 500 tons gross tonnage and upwards or craft certified to
carry more than 450 passengers should be provided with at least
two radar installations. A second radar may also be provided
in craft of less than 500 tons gross tonnage or certified to
carry 450 passengers or less where environmental conditions
At least one radar should be equipped with facilities for plotting
which are at least as effective as a reflector plotter.
Adequate communication facilities should be provided between
the radar observer and the person in immediate charge of the
Each radar installation provided should be suitable for the
intended craft speed, motion characteristics and commonly encountered
Each radar installation should be mounted so as to be as
free as practicable from vibration.
Where the area of operation of a high-speed craft is covered
by a reliable electronic position-fixing system, the craft should
be provided with the means to fix its position using such system.
indicator and rudder angle indicator.
A rate-of-turn indicator should be provided unless the Administration
determines otherwise. Means should be provided to warn the operator
if an operationally dictated maximum rate of turn is reached.
should be provided with an indicator showing the rudder angle.
In craft without a rudder, the indicator should show the direction
of steering thrust.
information provided by navigational systems should be so displayed
that the probability of misreading is reduced to a minimum and
should be capable of giving readings to an optimum accuracy.
Craft should be equipped with at least one adequate searchlight,
which should be controllable from the operating station.
portable signalling lamp capable of operating independently
of the crafts main electrical supply should be provided
and maintained ready for use in the operating compartment at
When operational conditions justify the provision of night vision
enhancement equipment, such equipment should be fitted.
Steering arrangement and propulsion indicators.
steering arrangement should be so designed that the craft turns
in the same direction as that of the wheel, tiller, joystick
or control lever.
Craft should be provided with indicators showing the mode of
the propulsion system(s).
Craft with emergency steering positions should be provided with
arrangements for supplying visual compass readings to the emergency
steering aid (automatic pilot equipment)
Craft should, where possible, be equipped with automatic
The alarm signalling facilities prescribed in paragraphs
3.1 and 3.2 of the Recommendation on performance standards for
automatic pilots, adopted by the Organization by resolution
A.342(IX), may be omitted.
Provision should be made to change from the automatic to manual
mode by a manual override.
data recorders (VDR)*
To assist in casualty investigation, passenger craft should
be fitted with a voyage data recorder (VDR) as follows:
ro-ro passenger craft, not later than the first survey
after 1 January 2003; and
passenger craft other than ro-ro passenger craft, not later
than 1 January 2004.
Administration may exempt passenger craft, other than ro-ro
passenger craft, from being fitted with a VDR where it can be
demonstrated that interfacing a VDR with the existing equipment
on the craft is unreasonable and impracticable.
The voyage data recorder (VDR) system, including all sensors,
should be subjected to an annual performance test. The test
should be conducted by an approved testing or servicing facility
to verify accuracy, duration and recoverability of the recorded
data. In addition, tests and inspections should be conducted
to determine the serviceability of all protective enclosure
and devices fitted to aid location. A copy of a certificate
of compliance issued by the testing facility stating the date
of compliance and the applicable performance standards should
be retained on board the craft.
* Refer to resolution A.861(20) on Recommendation on Performance
Standards for voyage data recorders (VDRs), adopted by the Organization
by resolution A.861(20)
charts and nautical publications
Craft should be provided with nautical charts and nautical publications
to plan and display the crafts route for the intended
voyage and to plot and monitor positions throughout the voyage.
An electronic chart display and information system (ECDIS) may
be accepted as meeting the chart carriage requirements of this
arrangements should be provided to meet the functional requirements
of 13.14.1, if this function is partly or fully fulfilled by
appropriate folio of paper charts may be used as a back-up arrangement
for ECDIS. Other back-up arrangements for ECDIS are acceptable
(See appendix 6 to Resolution A.817(19), as amended.)
identification system (AIS)
Craft should be provided with automatic identification system
(AIS) as follows:
in the case of passenger craft, not later than 1 July 2003;
in the case of cargo craft of 3,000 gross tonnage and upwards,
not later than 1 July 2006; and
in the case of cargo craft of less than 3,000 gross tonnage,
not later than 1 July 2007.
provide automatically to appropriately equipped shore stations,
other vessels and aircraft information, including the crafts
identity, type, position, course, speed, navigational status
and other safety-related information;
receive automatically such information from similarly
fitted vessels and craft;
monitor and track vessels; and
exchange data with shore based facilities.
The requirements of 13.15.2 should not be applied to cases where
international agreements, rules or standards provide for the
protection of navigational information.
AIS should be operated taking into account the guidelines developed
by the Organization.***
Refer to the guidelines on the operation of AIS on ships (IMO
equipment to which this chapter applies should be a type approved
by the Administration. Subject to 13.16.2, such equipment should
conform to performance standards not inferior to those adopted
by the Organization.
installed before the adoption of performance standards by the
Organization may be exempted from full compliance with the performance
standards having due regards to the criteria which the Organization
may adopt in connection with such standards.
