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 craft.
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
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 a t 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 so require.
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 craft.
Each radar installation provided should be suitable for the intended
craft speed, motion characteristics and commonly encountered environmental
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
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 all times.
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
Craft with emergency steering positions should be provided with arrangements
for supplying visual compass readings to the emergency steering position.
steering aid (automatic pilot equipment)
Craft should, where possible, be equipped with automatic pilot equipment.
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
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
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
Refer to resolution A.861(20) on Recommendation on Performance Standards
for voyage data recorders (VDRs), adopted by the Organization by resolution
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 paragraph.
arrangements should be provided to meet the functional requirements
of 13.14.1, if this function is partly or fully fulfilled by electronic
identification system (AIS)
Craft should be provided with automatic identification system (AIS)
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
receive automatically such information from similarly fitted vessels
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
AIS should be operated taking into account the guidelines developed
by the Organization.**
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.
