SECTION 1 PRINCIPLES OF APPLICATION OF THE HSC CODE

A. GeneralA 100 HSLC rules101 The HSLC rules are applicable to a variety of craft, someunder international conventions, some under domestic legisla-tion only and others under no regulations other than voluntaryclassification rules. This section states the principles of appli-cation of the HSLC rules and relation to the HSC Code.102 The basic requirements of the rules given by the classnotation 1A1 as specified by Part 2, 3 and 4 are valid for allcraft regardless of the safety certificate to be issued.103 The type and service notations Passenger, Cargo,Patrol etc. specify the general requirements to the craft in ad-dition to the 1A1 requirements.104 The additional equipment requirements E0, NAUT etc.specify extra voluntary requirements to any HSLC.

A 200 DSC Code201 The Code of Safety for Dynamically Supported Craft(DSC Code) has been the basis for the HSLC rules in the peri-od from the 1985 edition to the 1996 edition of the rules.202 This DSC Code does not apply to any craft the keel ofwhich is laid or which is subject to repairs, alterations or mod-ifications of a major character, on or after 96.01.01.203 For craft constructed and in service under the DSCCode, this Code is still valid standard although guidance in theinterpretation of the DSC Code may be obtained from the HSCCode.

A 300 HSC Code301 The International Code of Safety for High Speed Craft(HSC Code) replaces the DSC Code as basis for HSLC underinternational legislation.302 The HSC Code applies from 1 July 1996 to the notationsPassenger, Car Ferry and Cargo in international trade forthe distance from safe harbour in accordance with the Code.303 The HSC Code does not apply to the full extent to thenotations Crew, Yacht and Patrol although many of the re-quirements are equivalent.304 The present HSLC rules reflect the basic philosophy ofthe HSC Code and the requirements are applied in the variousParts and Chapters of the rules to the extent found applicableby the Society.305 Text quoted from the International Code of Safety forHigh Speed Craft is printed in italics.

B. ApplicationB 100 Non-convention craft101 Craft with the type and service notations Patrol, Yachtand Crew may be given a letter of compliance on those partsof the HSC Code which may have been applied for the actualcraft.

B 200 Domestic trade201 HSLC with the notations Passenger, Car Ferry orCargo in domestic trade and service restriction R3, R4 or R5may be classed based on compliance with domestic legislationas far as this is found equivalent to the standard of the HSCCode by the flag state.

202 Such equivalent requirements shall be referred to in theappendix of the class certificate and the corresponding require-ments of the rules which they replace and it is to be specifiedthat the craft is built for domestic trade.

B 300 International trade301 For international trade compliance with the HSC Codeshall be provided. Full compliance with the technical part ofthe HSC Code covered by the class is provided for craft withservice restrictions R0, R1 and R2.

Guidance note:Additional requirements given by other Codes and Conventionsthan SOLAS such as ILLC and MARPOL may be applicable tothe craft as decided by the flag state.

C. IMO RegulationsC 100 Chapter X of SOLAS101 The HSC Code becomes a mandatory part of SOLAS bychapter X, of which the relevant part is quoted below:SAFETY MEASURES FOR HIGH SPEED CRAFTRegulation 1 - DefinitionsFor the purpose of this chapter:1 'High Speed Craft Code (HSC Code)' means the InternationalCode of Safety for High Speed Craft adopted by the MaritimeSafety Committee of the Organization by resolutionMSC.36(63), as may be amended by the Organization, provid-ed that such amendments are adopted, brought into force andtake effect in accordance with the provisions of article VIII of thepresent Convention concerning the amendment proceduresapplicable to the Annex other than chapter I.2 'High speed craft' is a craft capable of maximum speed equalto or exceeding:

3.7 ∇ 0.1667 (m/s)where:

∇ = displacement corresponding to the design waterline (m3).3 The expression 'craft constructed' means a craft the keel ofwhich is laid or which is at a similar stage of construction.4 The term 'similar stage of construction' means a stage atwhich:

.1 construction identifiable with a specific craft begins;and

.2 assembly of that craft has commenced comprising atleast 50 tonnes or 1% of the estimated mass of a//structural material, whichever is less.

Regulation 2 - Application1 This chapter applies to high speed craft constructed on or af-ter 1 January 1996 which are engaged in international voyages.

C 200 Preamble of the HSC Code1 The international conventions ratified in respect of conven-tional ships and the regulations applied as a consequence ofsuch conventions have largely been developed having in mindthe manner in which conventional ships are constructed andoperated. Traditionally, ships have been built of steel and withthe minimum of operational controls. The requirements for

DET NORSKE VERITAS

ships engaged on long international voyages are thereforeframed in such a way that, providing the ship is presented forsurvey and a ship safety certificate is issued, the ship may goanywhere in the world without any operational restrictions beingimposed. Providing the ship is not involved in a casualty, all thatis needed is that it is made available to the Administration forthe purpose of a satisfactory resurvey before the ship safetycertificate expires and the certificate will be reissued.2 The traditional method of regulating ships should not be ac-cepted as being the only possible way of providing an appropri-ate level of safety. Nor should it be assumed that anotherapproach, using different criteria, could not be applied. Over along period of years, numerous new designs of marine vehicleshave been developed and have been in service. While these donot fully comply with the provisions of the international conven-tions relating to conventional ships built of steel, they havedemonstrated an ability to operate at an equivalent level ofsafety when engaged on restricted voyages under restrictedoperational weather conditions and with approved maintenanceand supervision schedules.3 This Code has been derived from the previous Code of Safetyfor Dynamically Supported Craft (DSC) adopted by IMO in1977. The Code recognized that safety levels can be signifi-cantly enhanced by the infrastructure associated with regularservice on a particular route, whereas the conventional shipsafety philosophy relies on the ship being self-sustaining withall necessary emergency equipment being carried on board.This revised Code has been prepared in recognition of thegrowth in size and types of high speed craft now existing and isintended to facilitate future research and development of fastsea transportation in order that they may be accepted interna-tionally.4 The safety philosophy of this Code is based on the manage-ment and reduction of risk as well as the traditional philosophyof passive protection in the event of an accident. Managementof risk through accommodation arrangement, active safety sys-tems, restricted operation, quality management and human fac-tors engineering should be considered in evaluating safetyequivalent to current conventions. Application of mathematicalanalysis should be encouraged to assess risk and determinethe validity of safety measures.5 The Code takes into account that a high speed craft is of afight displacement compared with a conventional ship. This dis-placement aspect is the essential parameter to obtain fast andcompetitive sea transportation and consequently this Code al-lows for use of non-conventional shipbuilding materials, provid-ed that a safety standard at least equivalent to conventionalships is achieved.6 To clearly distinguish such craft, criteria based on speed andvolumetric Froude number have been used to delineate thosecraft to which this Code applies from other, more conventional,craft.7 The Code requirements also reflect the additional hazardswhich may be caused by the high speed compared with con-ventional ship transportation. Thus, in addition to the normal re-quirements including life-saving appliances, evacuationfacilities, etc., provided in case of an accident occurring, furtheremphasis is placed on reducing the risk of hazardous situationsarising. Some advantages result from the high speed craft con-cept, i.e. the light displacement provides a large reserve buoy-ancy in relation to displacement, reducing the hazardsaddressed by the International Load Line Convention. The con-sequences of other hazards such as of collision at high speedare balanced by more stringent navigational and operational re-quirements and specially developed accommodation provi-sions.8 The above-mentioned safety concepts were originally reflect-ed in the Code of Safety for Dynamically Supported Craft. Thedevelopment of novel types and sizes of craft has led to the de-velopment of pressures within the maritime industry for craft

which are not dynamically supported cargo craft, passengercraft carrying larger numbers of passengers or operating furtherafield than permitted by that Code to be certified according tothose concepts. Additionally, improvements of maritime safetystandards since 1977 were required to be reflected in the revi-sions of the Code to maintain safety equivalence with conven-tional ships.9 Accordingly, two differing principles of protect/on and rescuewere developed.10 The first of these recognizes the craft which were originallyforeseen at the time of development of the DSC Code. Whererescue assistance is readily available and the total number ofpassengers is limited, a reduction in passive and active protec-tion may be permitted. Such craft are called "assisted craft" andform the basis for "category A passenger craft" of this Code.11 The second concept recognizes the further development ofhigh speed craft into larger craft. Where rescue assistance isnot readily available or the number of passengers is unlimited,additional passive and active safety precautions are required.These additional requirements provide for an area of safe ref-uge on board, redundancy of vital systems, increased water-tight and structural integrity and full fire-extinguishing capability.Such craft are called "unassisted craft" and form the basis for"cargo craft" and "category B passenger craft" of this Code.12 These two concepts of the Code have been developed as aunified document on the basis that an equivalent level of safetyto that normally expected on ships complying with the Interna-tional Convention for the Safety of Life at Sea is achieved.Where the application of new technology or design indicates anequivalent safety level to the strict application of the Code, theAdministration is permitted to formally recognize such equiva-lence.13 It is important that an Administration, in considering the suit-ability of a high speed craft under this Code, should apply allsections of the Code because non-compliance with any part ofthe Code could result in an imbalance which would adverselyaffect the safety of the craft, passengers and crew. For a similarreason, modifications to existing craft, which may have an ef-fect on safety, should be approved by the Administration.14 In developing the Code, it has been considered desirable toensure that high speed craft do not impose unreasonable de-mands on existing users of the environment or conversely suf-fer unnecessarily through lack of reasonable accommodationby existing users. Whatever burden of compatibility there is, itshould not necessarily be laid wholly on the high speed craft.

C 300 Chapter 1 of the HSC Code: "General comments and requirements"301 The following text is quoted from Chapter 1 of the HSCCode:1.1 General commentsThis Code should be applied as a complete set of comprehen-sive requirements. It contains requirements for the design andconstruction of high speed craft engaged on international voy-ages, the equipment which should be provided and the condi-tions for their operation and maintenance. The basic aim of theCode is to set levels of safety which are equivalent to those ofconventional ships required by the International Convention forthe Safety of Life at Sea, 1974, as amended, (SOLAS Conven-tion) and International Convention on Load Lines, 1966 (LoadLine Convention) by the application of constructional andequipment standards in conjunction with strict operational con-trols.These rules contain additional requirements compared to theHSC Code to fulfil the expressed aim of the HSC Code to be acomplete alternative to both the SOLAS Convention and theLoad Line Convention. The additional requirements are relat-ed to the main watertight bulkheads including collision bulk-head, watertight and weathertight closing appliances such as

DET NORSKE VERITAS


doors and hatches, window glass thicknesses and the amountof reserve buoyancy provided by the freeboard as required bythe previous Code of Safety for Dynamically Supported Craft(the DSC Code), adopted as IMO res. A.373(X).The HSC Code does not aim to cover requirements related topollution prevention, and the MARPOL Convention has to bedealt with separately.1.2 General requirementsThe application of the provisions of this Code is subject to thefollowing general requirements that:

.1 the Code will be applied in its entirety:

.2 the management of the company operating the craft ex-ercises strict control over its operation and mainte-nance by a quality management system *;

.3 the management ensures that only persons qualified tooperate the specific type of craft used on the intendedroute are employed;

.4 the distances covered and the worst intended condi-tions in which operations are permitted will be restrictedby the imposition of operational limits;

.5 the craft will at all times be in reasonable proximity to aplace of refuge;

.6 adequate communications facilities, weather forecastsand maintenance facilities are available within the areaof operation;

.7 in the intended area of operation there will be suitablerescue facilities readily available;

.8 areas of high fire risk such as machinery spaces andspecial category spaces are protected with fire-resist-ant materials and fire-extinguishing systems to ensure,as far as is practicable, containment and rapid extin-guishing of fire;

.9 efficient facilities are provided for the rapid and safeevacuation of all persons into survival craft;

.10 that all passengers and crew are provided with seats;

.11 that no enclosed sleeping berths for passengers areprovided;

.12 where the Administration has made a comprehensivereview of the adequacy of the fire safety measures andevacuation procedures for the crew accommodation,sleeping berths for crew may be permitted.

Thesurvey should be such as to ensure that the necessaryrepairs or renewals have been effectively made, that thematerial and workmanship of such repairs or renewalsare in all respects satisfactory, and that the craft com-plies in all respects with the requirements of the Code.

1.5.3 The periodical surveys referred to in 1.5.1.3 should be en-dorsed on the High Speed Craft Safety Certificate.1.5.4 The inspection and survey of the craft, so far as regardsthe enforcement of the provisions of the Code, should be car-ried out by officers of the Administration. The Administrationmay, however, entrust the inspections and surveys either tosurveyors nominated for the purpose or to organizations recog-nized by it.1.5.5 An Administration nominating surveyors or recognizingorganizations to conduct inspections and surveys as set forth in1.5.4 should, as a minimum, empower any nominated surveyoror recognized organization to:

.1 require repairs to a craft; and

.2 carry out inspections and surveys if requested by theappropriate authorities of a port State.

The Administration should notify the Organization of thespecific responsibilities and conditions of the authority delegat-ed to nominated surveyors or recognized organizations.1.5.6 When a nominated surveyor or recognized organizationdetermines that the condition of the craft or its equipment doesnot correspond substantially with the particulars of the certifi-cate or is such that the craft is not fit to operate without dangerto the craft or persons on board, such surveyor or organizationshould immediately ensure that corrective action is taken andshould, in due course, notify the Administration. If such correc-tive action is not taken the certificate should be withdrawn andthe Administration should be notified immediately; and, if thecraft is in an area under the jurisdiction of another Government,the appropriate authorities of the port State should be notifiedimmediately. When an officer of the Administration, a nominat-ed surveyor or recognized organization has notified the appro-priate authorities of the port State, the Government of the portState concerned should give such officer, surveyor or organiza-tion any necessary assistance to carry out their obligations un-der this section. When applicable, the Government of the portState concerned should ensure that the craft should not contin-ue to operate until it can do so without danger to the craft or thepersons on board.1.5.7 In every case, the Administration should fully guaranteethe completeness and efficiency of the inspection and survey,and should undertake to ensure the necessary arrangements tosatisfy this obligation.1.6 ApprovalsThe owner of a craft should accept the obligation to supply suf-ficient information to enable the Administration to fully assessthe features of the design. It is strongly recommended that theowner and Administration and, where appropriate, the portState or States, commence discussions at the earliest possiblestage so that the Administration may fully evaluate the designin determining what additional or alternative requirementsshould be applied to the craft to achieve the required level ofsafety.1.7 Maintenance of conditions after survey1.7.1 The condition of the craft and its equipment should bemaintained to conform with the provisions of this Code to en-sure that the craft in all respects will remain fit to operate with-out danger to the craft or the persons on board.1.7.2 After any survey of the craft under 1.5 has been complet-ed, no change should be made to structure, equipment, fittings,arrangements and materials covered by the survey, without thesanction of the Administration.1.7.3 Whenever an accident occurs to a craft or a defect is dis-covered, either of which affects the safety of the craft or the ef-ficiency or completeness of structure, equipment, fittings,arrangements and materials, the person in charge or owner ofthe craft should report at the earliest opportunity to the Admin-istration, the nominated surveyor or recognized organization re-

DET NORSKE VERITAS


sponsible, who should cause investigations to be initiated todetermine whether a survey, as required by 1.5, is necessary.If the craft is in an area under the jurisdiction of another Gov-ernment, the person in charge or the owner should also reportimmediately to the appropriate authorities of the port State andthe nominated surveyor or recognized organization should as-certain that such a report has been made.1.8 High Speed Craft Safety Certificate1.8.1 A certificate called a High Speed Craft Safety Certificateis issued after completion of an initial or renewal survey to acraft which complies with the requirements of the Code. Thecertificate should be issued or endorsed either by the Adminis-tration or by any person or organization recognized by it. In eve-ry case, that Administration assumes full responsibility for thecertificate.1.8.2 A Contracting Government to the Convention may, at therequest of the Administration, cause a craft to be surveyed and,if satisfied that the requirements of the Code are complied with,should issue or authorize the issue of a certificate to the craftand, where appropriate, endorse or authorize the endorsementof a certificate on the craft in accordance with the Code. Anycertificate so issued should contain a statement to the effectthat it has been issued at the request of the Government of theState the flag of which the craft is entitled to fly, and it shouldhave the same force and receive the same recognition as a cer-tificate issued under 1.8.1.1.8.3 The certificate should be that of the model given in annex1 to the Code. If the language used is neither English norFrench, the text should include a translation into one of theselanguages.

Guidance note:Annex 1 of the HSC Code is not included in the HSLC Rules.


1.8.4 The High Speed Craft Safety Certificate should be issuedfor a period specified by the Administration which should not ex-ceed five years.1.8.5 Notwithstanding the requirements of 1.8.4, when the re-newal survey is completed within three months before the expi-ry date of the existing certificate, the new certificate should bevalid from the date of completion of the renewal survey to a datenot exceeding five years from the date of expiry of the existingcertificate.1.8.6 When the renewal survey is completed after the expirydate of the existing certificate, the new certificate should be val-id from the date of completion of the renewal survey to a datenot exceeding five years from the date of expiry of the existingcertificate.1.8.7 When the renewal survey is completed more than threemonths before the expiry date of the existing certificate, the newcertificate should be valid from the date of completion of the re-newal survey to a date not exceeding five years from the dateof completion of the renewal survey.1.8.8 If a certificate is issued for a period of less than five years,the Administration may extend the validity of the certificate be-yond the expiry date to the maximum period specified in 1.8.4,provided that the surveys when a certificate is issued for a pe-riod of five years are carried out.1.8.9 If a renewal survey has been completed and a new certificatecannot be issued or placed on board the craft before the expirydate of the existing certificate, the person or organization author-ized by the Administration may endorse the existing certificate andsuch a certificate should be accepted as valid for a further periodwhich should not exceed 5 months from the expiry date.1.8.10 If a craft at the time when a certificate expires is not inthe place in which it is to be surveyed, the Administration mayextend the period of validity of the certificate but this extensionshould be granted only for the purpose of allowing the craft to

proceed to the place in which it is to be surveyed, and then onlyin cases where it appears proper and reasonable to do so. Nocertificate should be extended for a period longer than onemonth, and a craft to which an extension is granted should not,on its arrival in the place in which it is to be surveyed, be entitledby virtue of such extension to leave that place without having anew certificate. When the renewal survey is completed, the newcertificate should be valid to a date not exceeding five yearsfrom the date of expiry of the existing certificate before the ex-tension was granted.1.8.11 In special circumstances, as determined by the Admin-istration, a new certificate need not be dated from the date ofexpiry of the existing certificate as required by 1.8.6 or 1.8.10.In these circumstances, the new certificate should be valid to adate not exceeding five years from the date of completion of therenewal survey.1.8.12 If a periodical survey is completed before the periodspecified in 1.5, then:

.1 the anniversary date shown on the relevant certificateshould be amended by endorsement to a date whichshould not be more than three months later than thedate on which the survey was completed;

.2 the subsequent periodical survey required by 1.5should be completed at the intervals prescribed by 1.5using the new anniversary date; and

.3 the expiry date may remain unchanged provided one ormore periodical surveys are carried out so that the max-imum intervals between the surveys prescribed by1.5.1.3 are not exceeded.

1.8.13 A certificate issued under 1.8.1 or 1.8.2 should cease tobe valid in any of the following cases:

.1 if the relevant surveys are not completed within the pe-riods specified in 7.5.1;

.2 if the certificate is not endorsed in accordance with1.5.3; or

.3 upon transfer of the craft to the flag of another State. Anew certificate should only be issued when the Govern-ment issuing the new certificate is fully satisfied that thecraft is in compliance with the requirements of 1.7.1 and1.7.2. In the case of a transfer between Governmentsthat are Contracting Governments to the Convention, ifrequested within three months after the transfer hastaken place, the Government of the State whose flagthe craft was formerly entitled to fly should, as soon aspossible, transmit to the Administration a copy of thecertificate carried by the craft before the transfer and, ifavailable, copies of the relevant survey reports.

1.8.14 The privileges of the Code may not be claimed in favourof any craft unless it holds a valid certificate.1.9 Permit to Operate High Speed Craft1.9.1 The craft should not operate commercially unless a Per-mit to Operate High Speed Craft is issued and valid in additionto the High Speed Craft Safety Certificate. Transit voyage with-out passengers or cargo may be undertaken without the Permitto Operate High Speed Craft.1.9.2 The Permit to Operate High Speed Craft should be issuedby the Administration to certify compliance with 1.2.2 to 1.2.7and stipulate conditions of the operation of the craft and drawnup on the basis of the information contained in the route opera-tional manual specified in chapter 18 of this Code.

Guidance note:Chapter 18 covers operational requirements, which is currentlynot included in the HSLC rules.


1.9.3 Before issuing the Permit to Operate, the Administrationshould consult with each port State to obtain details of any op-

DET NORSKE VERITAS


erational conditions associated with operation of the craft in thatState. Any such conditions imposed should be shown by theAdministration on the Permit to Operate and included in theroute operational manual.1.9.4 A port State may inspect the craft and audit its documen-tation for the sole purpose of verifying its compliance with thematters certified by and conditions associated with the Permitto Operate. Where deficiencies are shown by such an audit, thePermit to Operate ceases to be valid until such deficiencies arecorrected or otherwise resolved.1.9.5 The provisions of 1.8 should apply to the issue and the pe-riod of validity of the Permit to Operate High Speed Craft.1.9.6 The Permit to Operate High Speed Craft should be that ofthe model given in annex 2 to this Code. If the language usedis neither English nor French, the text should include a transla-tion into one of these languages.

Guidance note:Annex 2 of the HSC Code is not included in the HSLC rules.


1.10 ControlThe provisions of regulation I/19 of the Convention should beapplied to include the Permit to Operate High Speed Craft in ad-dition to the certificate issued under 1.8.1.11 Equivalents1.11.1 Where this Code requires that a particular fitting, mate-rial, appliance or apparatus, or type thereof, should be fitted orcarried in a craft, or that any particular provision should bemade, the Administration may allow any other fitting, material,appliance or apparatus, or type thereof, to be fitted or carried,or any other provision to be made in that craft, if it is satisfied bytrial thereof or otherwise that such fitting, material, appliance orapparatus, or type thereof, or provision, is at least as effectiveas that required by this Code.1.11.2 Where compliance with any of the requirements of thisCode would be impractical for the particular designs of the craft,the Administration may substitute those with alternative re-quirements provided that equivalent safety is achieved. TheAdministration which allows any such substitution should com-municate to the Organization particulars of these substitutionsand the reasons therefor, which the Organization should circu-late to its Member Governments for their information.1.12 Information to be made available1.12.1 The Administration should ensure that the managementof the company operating the craft has provided the craft withadequate information and guidance in the form of manuals toenable the craft to be operated and maintained safely. Thesemanuals should include a route operational manual, craft oper-

ating manual, maintenance manual and servicing schedule.Such information should be updated as necessary.1.12.2 The manuals should contain at least the informationspecified in chapter 18 and should be in a language understoodby the crew. Where this language is not English, a translationinto English should be provided of at least the route operationalmanual and the craft operating manual.

Guidance note:Chapter 18 covers operational requirements, which is currentlynot included in the HSLC rules.


1.13 Further developments1.13.1 It is recognized that there is much ongoing research anddevelopment in the design of high speed craft and that newtypes may emerge which have different geometry to that envis-aged during the formulation of this Code. It is important that thisCode does not restrict this progress and the development ofnew designs.1.13.2 A design may be produced which cannot comply with theprovisions of this Code. In such a case the Administrationshould determine the extent to which the provisions of the Codeare applicable to the design and, if necessary, develop addi-tional or alternative requirements to provide an equivalent levelof safety for the craft.1.13.3 The foregoing should be considered by the Administra-tion when assessing the granting of equivalents under theCode.1.14 Circulation of safety information1.14.1 In the event that an Administration has cause to investi-gate an accident involving a craft to which this Code applies,that Administration should provide a copy of the official reportto the Organization, which will invite Member States to note theexistence of the report and to obtain a copy.1.14.2 In the event that operational experience reveals structur-al or equipment failures affecting the safety of a design, craftowners should inform the Administration.1.15 Review of the Code1.15.1 The Code should be reviewed by the Organization at in-tervals preferably not exceeding four years to consider revisionof existing requirements to take account of new developmentsin design and technology.1.15.2 Where a new development in design and technology hasbeen found acceptable to an Administration, that Administrationmay submit particulars of such development to the Organiza-tion for consideration for incorporation into the Code during pe-riodical review.

SECTION 3 FLAG ADMINISTRATION REQUIREMENTS

A. GeneralA 100 IMO HSC Code - General101 The IMO HSC Code has a number of requirementswhich are left to the Flag State Administration to decide uponwith respect to the specific interpretation of the requirement.The Code text often uses the expression that the requirementshould be "to the satisfaction of the Administration".102 The goal for international regulations is to have as uni-form requirements as possible. Most requirements which con-tain the expression "to the satisfaction of the Administration"have been removed from IMO documents as far as practicable.103 Those requirements which are dependant on local or do-mestic conditions are still up to the Administration to decide.104 DNV aims at a uniform set of requirements both to be astransparent as possible and also to be specific in contractualand statutory matters. Consequently, a number of the "up to theAdministration" requirements of the HSC Code has been inter-preted by DNV.105 The cross references between the HSC Code and theDNV rules refer to all requirements in the HSC Code where theFlag or Port State is mentioned in connection with a require-ment.106 The HSC Code paragraphs left to the Administration todecide, and the corresponding DNV paragraph with commentsare given in the following. HSC Code paragraphs are given byx.x.x and DNV paragraphs by Pt.y Ch.y Sec.y.

A 200 HSC Code chapter 1201 1.2.12 concerning evacuation procedures required for crewsleeping berths, see Sec.1 C300 for information. Specific re-quirements are to be developed in each case.1.4.10.1 concerning criteria for maximum rescue time for cat-egory A craft, see Sec.1 C300 for information. This is an oper-ational condition and has to be agreed between Flag and PortState(s) of the route in question.1.4.29 concerning maximum operational weight in the intend-ed mode, see Sec.1 C300 for information. Unless otherwise de-fined, this definition should correspond to the maximumdisplacement as defined in Pt.3 Ch. 1 Sec. 1 D101.1.4.48 concerning parameters for worst intended condition, seeSec.1 C300 for information. Unless otherwise defined, thisdefinition should correspond to the restrictions given by designaccelerations in Pt.3 Ch.1 Sec.2 B200, and given in the appen-dix to the class certificate, see Pt.3 Ch.1 Sec.2 A105.1.5.1.2 concerning renewal survey intervals, see Sec.1 C300for information. Pt.7 Ch.2 Sec.1 A100 specify 5 years for mainclass notation 1A1 HSLC and 3 years for 1A2 HSLC See alsoPt.1 Ch.1 Sec.2 B302 for the notation 1A2 HSLC.1.5.4 concerning recognised organisations, see Sec.1 C300 forinformation. DNV is a recognised classification society.1.5.5 concerning recognised organisation, see 1.5.4.1.5.6 concerning recognised organisation, see 1.5.4.1.5.7 concerning Administrations' responsibility for complete-ness of inspections and surveys carried out by recognised or-ganisations, see 1.5.4 and Pt.1 Ch.1 Sec.1 B602 with respect toinformation to the Flag Administration of the craft.1.6 concerning approvals, see 1.5.4 to 1.5.7 above, and Pt.1Ch.1 Sec. 3 A500 for plan approval.

1.7.2 concerning changes after initial survey, see Sec.1 C300for information and Pt.1 Ch.1 Sec.3 B for retention of class.1.8.1 concerning issue of High Speed Craft Safety Certificate,see Sec.1 C300 for information. This certificate is issued whenDNV acts on behalf of a Flag Administration on basis of dele-gated authority.1.8.11 concerning circumstances for issue of certificate, seeSec.1 C300 for information and Pt.1 Ch.1 Sec.3 B800 for issu-ance and validity of certificates.1.11.1 concerning acceptance of equivalents, see Sec.1 C300for information and Pt.1 Ch.1 Sec.1 B306 and B307 with re-spect to equivalent alternatives.1.11.2 concerning alternative requirements, see 1.11.1. TheSociety does not have the possibility of applying alternative re-quirements which are not found to be equivalent, unless suchalternative requirements are accepted by Flag State for owndomestic service or reported by Flag State to IMO for craft in-tended for international service.1.12.1 concerning sufficient manuals, see Sec.1 C300 for in-formation. HSC Code chapter 18 is not included in the Rulesfor HSLC. This chapter covers the Permit to Operate «certifi-cate», which is not covered by the class certificate.1.13.2 concerning provisions for craft outside the Code, seeSec.1 C300 for information. This paragraph of the HSC Codeis in conflict with paragraph 1.2.1 of the same Code, and equiv-alent solutions should be established. See comment under1.11.1.1.13.3 concerning equivalents for craft outside the Code, see1.13.2.1.14.2 concerning craft owner's obligation to inform the ad-ministration, see Sec.1 C300 for information, and Pt.1 Ch.1Sec.3 B101 with respect to the owners duty to inform the class.
