A 100 Application

101 The requirements in this Chapter apply to all high speedcraft for the assignment of main class. Text quoted from the1994 International Code of Safety for High-Speed Craft (HSCCode) is printed in italics.

102 This Code applies to high speed craft which are engagedin international voyages.

(HSC Code 1.3.1)

103 This Code applies to:

.1 passenger craft which do not proceed in the course of theirvoyage more than 4 h at operational speed from a place ofrefuge when fully laden; and

.2 cargo craft of 500 gross tonnage and upwards which donot proceed in the course of their voyage more than 8 h atoperational speed from a place of refuge when fully laden.

(HSC Code 1.3.2)

104 This chapter does not apply to craft to which this Codewould otherwise apply while such craft are being navigatedwithin the Great Lakes of North America and their connectingand tributary waters as far east as the lower exit of the St. Lam-bert Lock at Montreal in the Province of Quebec, Canada.

(HSC Code 14.1.2)

Guidance note:

Such craft are subject to special requirements relative to radio for

safety purposes, as contained in the relevant agreement betweenCanada and the United States.

---e-n-d---of---G-u-i-d-a-n-c-e---n-o-t-e---

105 No provision in this chapter should prevent the use byany craft, survival craft or person in distress, of any means attheir disposal to attract attention, make known their positionand obtain help.

(HSC Code 14.1.3)

106 For the application of these rules, wherever the termAd-ministrationis quoted, except in 300 to 500, this is to be read asthe Society.

A 400 Alterations and additions

401 When an alteration or addition to the type approvedcomponent or sub-system, or the certified GMDSS system, is

proposed, plans covering alterations and additions are to besubmitted for approval. A survey is to verify that compliancewith these rules is maintained.

402 When mandatory or optional alterations are prescribedby the network organisation (INMARSAT, COSPAS-SAR-SAT), the quality assurance system recommended by the net-work organisation may be accepted to cover the approval andsurvey requirements of 401 for type approved components. Adetailed description of the technical modifications are to be

submitted.403 When mandatory alterations are prescribed by the net-work organisation (INMARSAT, COSPAS-SARSAT) theseare to be considered as requirements from the Society to main-tain type approval.

A 500 Exemptions

501 It is considered highly desirable not to deviate from therequirements of this chapter; nevertheless the Administration,in conjunction with the base port State, may grant partial or con-ditional exemptions to individual craft from the requirements of14.6(Sec.2 C100) to 14.10(Sec.2 C500)provided:

.1 such craft comply with the functional requirements of 14.4

(Sec.2 A100); and.2 the Administration has taken into account the effect such

exemptions may have upon the general efficiency of theservice for the safety of all ships and craft.

(HSC Code 14.3.1)

502 An exemption may be granted under 14.3.1(501) only:

.1 if the conditions affecting safety are such as to render thefull application of 14.6(Sec.2 C100) to 14.10(Sec.2 C500)unreasonable or unnecessary;

.2 in exceptional circumstances, for a single voyage outsidethe sea area or sea areas for which the craft is equipped;or

.3 prior to 1 February 1999, when the craft will be taken per-manently out of service within two years of a date pre-scribed by 14.1(100) for the application of requirementsfor this chapter.

C 600 Watches

601 Every craft, while at sea, should maintain a continuouswatch:

.1 on VHF DSC channel 70, if the craft, in accordance withthe requirements of 14.6.1.2(101.2) is fitted with a VHF ra-dio installation;

.2 on the distress and safety DSC frequency 2,187.5 kHz, ifthe craft, in accordance with the requirements of 14.8.1.2

(301.2) or 14.9.1.3(401.3) is fitted with an MF radio instal-lation:

.3 on the distress and safety DSC frequencies 2,187.5 kHzand 8,414.5 kHz and also on at least one of the distressand safety DSC frequencies 4,207.5 kHz, 6,312 kHz,

12,577 kHz or 16,804.5 kHz, appropriate to the time of dayand the geographical position of the craft, if the craft, in ac-cordance with the requirements of 14.9.2.2 (402.2) or14.10.1 (501) is fitted with an MF/HF radio installation.This watch may be kept by means of a scanning receiver;

.4 for satellite shore-to-ship distress alerts, if the craft, in ac-

cordance with the requirements of 14.9.1.1(401.1) is fittedwith an INMARSAT ship earth station.

(HSC Code 14.11.1)

602 Every craft, while at sea, should maintain a radio watchfor broadcasts of maritime safety information on the appropriatefrequency or frequencies on which such information is broad-

cast for the area in which the craft is navigating.

(HSC Code 14.11.2)

603 Until 1 February 1999 or until such other date as may bedetermined by the Maritime Safety Committee, every craft whileat sea should maintain, when practicable, a continuous listen-ing watch on VHF channel 16. This watch should be kept at the

position from which the craft is normally navigated.(HSC Code 14.11.3)

604 Until 1 February 1999 or until such other date as may bedetermined by the Maritime Safety Committee, every craft re-quired to carry a radiotelephone watch receiver should main-tain, while at sea, a continuous watch on the radiotelephone

distress frequency 2,182 kHz. This watch should be kept at theposition from which the craft is normally navigated.

(HSC Code 14.11.4)

C 700 Sources of energy

701 There should be available at all times, while the craft is at

sea, a supply of electrical energy sufficient to operate the radioinstallations and to charge any batteries used as part of a re-serve source of energy for the radio installations.

(HSC Code 14.12.1)

702 Reserve and emergency sources of energy should beprovided on every craft to supply radio installations, for the pur-pose of conducting distress and safety radio communications,

in the event of failure of the crafts main source of electricalpower. The reserve source of energy should be capable of si-

multaneously operating the VHF radio installation required by14.6.1.1 (101.1) and, as appropriate for the sea area or sea ar-eas for which the craft is equipped, either the MF radio installa-tion required by 14.8.1.1(301.1), the MF/HF radio installation

required by 14.9.2.1(402.1) or 14.10.1(501) or the INMARSATship earth station required by 14.9.1.1(401.1) and any of theadditional loads mentioned in 14.12.5(705) and 14.12.8(708)for a period of at least 1 h.

(HSC Code 14.12.2)

703 The reserve source of energy should be independent ofthe propelling power of the craft and the crafts electrical sys-

tem.

(HSC Code 14.12.3)

704 Where, in addition to the VHF radio installation, two ormore of the other radio installations, referred to in 14.12.2

(702), can be connected to the reserve source of energy, theyshould be capable of simultaneously supplying, for the periodspecified in 14.12.2(702), the VHF radio installation and:

.1 all other radio installations which can be connected to the

reserve source of energy at the same time; or

.2 whichever of the radio installations will consume the most

power, if only one of the other radio installations can be

connected to the reserve source of energy at the same

time as the VHF radio installation.

(HSC Code 14.12.4)

If the maintenance requirement is ensured by duplication ofequipment as described in 907, both the basic and duplicated

equipment is to be included in the determination of electricalload for the reserve source of energy unless simultaneouslysupply of both basic and duplicated equipment from reservesource of energy is inhibited. An arrangement provided for the

purpose of inhibiting simultaneous supply of both basic andduplicated equipment is to be in compliance with IMO Reso-lution A702(17).

705 The reserve source of energy may be used to supply theelectrical lighting required by 14.5.2.4(B102.4).

(HSC Code 14.12.5)

706 Where a reserve source of energy consists of a re-chargeable accumulator battery or batteries:

.1 a means of automatically charging such batteries should

be provided which should be capable of recharging them

to minimum capacity requirements within 10 h; and

.2 the capacity of the battery or batteries should be checked,

using an appropriate method, at intervals not exceeding 12

months, when the craft is not at sea.

(HSC Code 14.12.6)

.3 a low voltage alarm should be provided.

Guidance note:

One method of checking the capacity of an accumulator batteryis to fully discharge and recharge the battery, using normal oper-

ating current and period (e.g. 10 h). Assessment of the chargecondition can be made at any time, but it should be done withoutsignificant discharge of the battery when the craft is at sea.


707 The siting and installation of accumulator batteries whichprovide a reserve source of energy should be such as to en-

sure:

.1 the highest degree of service;

.2 a reasonable lifetime;

.3 reasonable safety;

.4 that the battery temperatures remain within the manufac-

turers specifications whether under charge or idle; and

.5 that when fully charged, the batteries will provide at least

the minimum required hours of operation under all weather

conditions.

C 900 Maintenance requirements

901 Equipment should be so designed that the main units canbe replaced readily without elaborate recalibration or readjust-ment.

(HSC Code 14.14.1)

902 Where applicable, equipment should be so constructedand installed that it is readily accessible for inspection and on-board maintenance purposes.

(HSC Code 14.14.2)

903 Adequate information should be provided to enable theequipment to be properly operated and maintained, taking intoaccount the recommendations of the Organisation.

(HSC Code 14.14.3)

Guidance note:

See the Recommendation on general requirements for shipborneradio equipment forming part of the Global Maritime Distressand Safety System and for electronic navigational aids, adoptedby the Organisation (IMO) by resolution A.694(17).


904 Adequate tools and spares should be provided to enableequipment to be maintained.

(HSC Code 14.14.4)

905 The Administration should ensure that radio equipmentrequired by this chapter is maintained to provide the availabilityof the functional requirements specified in 14.4(A100) and tomeet the recommended performance standards of such equip-ment.

(HSC Code 14.14.5)

906 On craft engaged on voyages in sea areas A1 and A2,the availability should be ensured by using such methods asduplication of equipment, shore-based maintenance or at-seaelectronic maintenance capability, or a combination of these, asmay be approved by the Administration.

(HSC Code 14.14.6)

907 On craft engaged on voyages in sea areas A3 and A4,the availability should be ensured by using a combination of atleast two methods such as duplication of equipment, shore-based maintenance or at-sea electronic maintenance capabili-ty, as may be approved by the Administration, taking into ac-count the recommendations of the Organisation.

(HSC Code 14.14.7)

Guidance note:

Administrations should take account of the Recommendations onradio maintenance guidelines for the Global Maritime Distressand Safety System (GMDSS) related to sea areas A3 and A4,adopted by the Organisation (IMO) by resolution A.702(17).


908 However, craft operating solely between ports where ad-equate facilities for shore-based maintenance of the radio in-stallations are available and provided no journey between twosuch ports exceeds six hours, then the Administration may ex-empt such craft from the requirement to use at least two main-
