Rules for High Speed, Light Craft and Naval Surface Craft, January 2011 Pt.0 Ch.6 Sec.1 –

SECTION 1 PRINCIPLES OF APPLICATION OF THE HSC CODE

A. General

A 100 HSLC rules101 The HSLC rules are applicable to a variety of craft, some under international conventions, some underdomestic legislation only and others under no regulations other than voluntary classification rules. This sectionstates the principles of application of the HSLC rules and relation to the HSC Code.102 The basic requirements of the rules given by the class notation 1A1 as specified by Part 2, 3 and 4 arevalid for all craft regardless of the safety certificate to be issued.103 The type and service notations Passenger, Cargo, Patrol etc. specify the general requirements to thecraft in addition to the 1A1 requirements.104 The additional equipment requirements E0, NAUT etc. specify extra voluntary requirements to anyHSLC.

A 200 DSC Code

201 The Code of Safety for Dynamically Supported Craft (DSC Code) has been the basis for the HSLC rulesin the period from the 1985 edition to the 1996 edition of the rules.

202 This DSC Code does not apply to any craft the keel of which is laid or which is subject to repairs,alterations or modifications of a major character, on or after 96.01.01.

203 For craft constructed and in service under the DSC Code, this Code is still valid standard althoughguidance in the interpretation of the DSC Code may be obtained from the HSC Code.

A 300 HSC Code301 The International Code of Safety for High Speed Craft (HSC Code) replaces the DSC Code as basis forHSLC under international legislation.302 The HSC Code applies from 1 July 1996 to the notations Passenger, Car Ferry and Cargo ininternational trade for the distance from safe harbour in accordance with the Code.303 The HSC Code does not apply to the full extent to the notations Crew, Yacht and Patrol although manyof the requirements are equivalent.304 The present HSLC rules reflect the basic philosophy of the HSC Code and the requirements are appliedin the various Parts and Chapters of the rules to the extent found applicable by the Society.

305 Text quoted from the International Code of Safety for High Speed Craft is printed in italics.

B. Application

B 100 Non-convention craft101 Craft with the type and service notations Patrol, Yacht and Crew may be given a letter of complianceon those parts of the HSC Code which may have been applied for the actual craft.

B 200 Domestic trade

201 HSLC with the notations Passenger, Car Ferry or Cargo in domestic trade and service restrictionR3, R4 or R5 may be classed based on compliance with domestic legislation as far as this is found equivalentto the standard of the HSC Code by the flag state.202 Such equivalent requirements shall be referred to in the appendix of the class certificate and thecorresponding requirements of the rules which they replace and it is to be specified that the craft is built fordomestic trade.

B 300 International trade301 For international trade compliance with the HSC Code shall be provided. Full compliance with thetechnical part of the HSC Code covered by the class is provided for craft with service restrictions R0, R1 andR2.

C. IMO RegulationsC 100 Chapter X of SOLAS101 The HSC Code becomes a mandatory part of SOLAS by chapter X, of which the relevant part is quotedbelow:SAFETY MEASURES FOR HIGH SPEED CRAFTRegulation 1 - DefinitionsFor the purpose of this chapter:1 'High Speed Craft Code (HSC Code)' means the International Code of Safety for High Speed Craft adoptedby the Maritime Safety Committee of the Organization by resolution MSC.36(63), as may be amended by theOrganization, provided that such amendments are adopted, brought into force and take effect in accordancewith the provisions of article VIII of the present Convention concerning the amendment procedures applicableto the Annex other than chapter I.2 'High speed craft' is a craft capable of maximum speed equal to 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 of which is laid or which is at a similar stage ofconstruction.4 The term 'similar stage of construction' means a stage at which:

.1 construction identifiable with a specific craft begins; and

.2 assembly of that craft has commenced comprising at least 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 after 1 January 1996 which are engaged ininternational voyages.

C 200 Preamble of the HSC Code1 The international conventions ratified in respect of conventional ships and the regulations applied as aconsequence of such conventions have largely been developed having in mind the manner in whichconventional ships are constructed and operated. Traditionally, ships have been built of steel and with theminimum of operational controls. The requirements for ships engaged on long international voyages aretherefore framed in such a way that, providing the ship is presented for survey and a ship safety certificate isissued, the ship may go anywhere in the world without any operational restrictions being imposed. Providingthe ship is not involved in a casualty, all that is needed is that it is made available to the Administration for thepurpose of a satisfactory resurvey before the ship safety certificate expires and the certificate will be reissued.2 The traditional method of regulating ships should not be accepted as being the only possible way of providingan appropriate level of safety. Nor should it be assumed that another approach, using different criteria, couldnot be applied. Over a long period of years, numerous new designs of marine vehicles have been developedand have been in service. While these do not fully comply with the provisions of the international conventionsrelating to conventional ships built of steel, they have demonstrated an ability to operate at an equivalent levelof safety when engaged on restricted voyages under restricted operational weather conditions and withapproved maintenance and supervision schedules.3 This Code has been derived from the previous Code of Safety for Dynamically Supported Craft (DSC)adopted by IMO in 1977. The Code recognized that safety levels can be significantly enhanced by theinfrastructure associated with regular service on a particular route, whereas the conventional ship safetyphilosophy relies on the ship being self-sustaining with all necessary emergency equipment being carried onboard. This revised Code has been prepared in recognition of the growth in size and types of high speed craftnow existing and is intended to facilitate future research and development of fast sea transportation in orderthat they may be accepted internationally.4 The safety philosophy of this Code is based on the management and reduction of risk as well as the traditional

DET NORSKE VERITAS


philosophy of passive protection in the event of an accident. Management of risk through accommodationarrangement, active safety systems, restricted operation, quality management and human factors engineeringshould be considered in evaluating safety equivalent to current conventions. Application of mathematicalanalysis should be encouraged to assess risk and determine the validity of safety measures.5 The Code takes into account that a high speed craft is of a fight displacement compared with a conventionalship. This displacement aspect is the essential parameter to obtain fast and competitive sea transportation andconsequently this Code allows for use of non-conventional shipbuilding materials, provided that a safetystandard at least equivalent to conventional ships is achieved.6 To clearly distinguish such craft, criteria based on speed and volumetric Froude number have been used todelineate those craft to which this Code applies from other, more conventional, craft.7 The Code requirements also reflect the additional hazards which may be caused by the high speed comparedwith conventional ship transportation. Thus, in addition to the normal requirements including life-savingappliances, evacuation facilities, etc., provided in case of an accident occurring, further emphasis is placed onreducing the risk of hazardous situations arising. Some advantages result from the high speed craft concept,i.e. the light displacement provides a large reserve buoyancy in relation to displacement, reducing the hazardsaddressed by the International Load Line Convention. The consequences of other hazards such as of collisionat high speed are balanced by more stringent navigational and operational requirements and speciallydeveloped accommodation provisions.8 The above-mentioned safety concepts were originally reflected in the Code of Safety for DynamicallySupported Craft. The development of novel types and sizes of craft has led to the development of pressureswithin the maritime industry for craft which are not dynamically supported cargo craft, passenger craft carryinglarger numbers of passengers or operating further afield than permitted by that Code to be certified accordingto those concepts. Additionally, improvements of maritime safety standards since 1977 were required to bereflected in the revisions of the Code to maintain safety equivalence with conventional ships.9 Accordingly, two differing principles of protect/on and rescue were developed.10 The first of these recognizes the craft which were originally foreseen at the time of development of the DSCCode. Where rescue assistance is readily available and the total number of passengers is limited, a reductionin passive and active protection may be permitted. Such craft are called "assisted craft" and form the basis for"category A passenger craft" of this Code.11 The second concept recognizes the further development of high speed craft into larger craft. Where rescueassistance is not readily available or the number of passengers is unlimited, additional passive and activesafety precautions are required. These additional requirements provide for an area of safe refuge on board,redundancy of vital systems, increased watertight 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" ofthis Code.12 These two concepts of the Code have been developed as a unified document on the basis that an equivalentlevel of safety to that normally expected on ships complying with the International Convention for the Safety ofLife at Sea is achieved. Where the application of new technology or design indicates an equivalent safety levelto the strict application of the Code, the Administration is permitted to formally recognize such equivalence.13 It is important that an Administration, in considering the suitability of a high speed craft under this Code,should apply all sections of the Code because non-compliance with any part of the Code could result in animbalance which would adversely affect the safety of the craft, passengers and crew. For a similar reason,modifications to existing craft, which may have an effect on safety, should be approved by the Administration.14 In developing the Code, it has been considered desirable to ensure that high speed craft do not imposeunreasonable demands on existing users of the environment or conversely suffer unnecessarily through lackof reasonable accommodation by existing users. Whatever burden of compatibility there is, it should notnecessarily 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 HSC Code:1.1 General commentsThis Code should be applied as a complete set of comprehensive requirements. It contains requirements forthe design and construction of high speed craft engaged on international voyages, the equipment which shouldbe provided and the conditions for their operation and maintenance. The basic aim of the Code is to set levelsof safety which are equivalent to those of conventional ships required by the International Convention for theSafety of Life at Sea, 1974, as amended, (SOLAS Convention) and International Convention on Load Lines,1966 (Load Line Convention) by the application of constructional and equipment standards in conjunction withstrict operational controls.These rules contain additional requirements compared to the HSC Code to fulfil the expressed aim of the HSCCode to be a complete alternative to both the SOLAS Convention and the Load Line Convention. Theadditional requirements are related to the main watertight bulkheads including collision bulkhead, watertight

DET NORSKE VERITAS


and weathertight closing appliances such as doors and hatches, window glass thicknesses and the amount ofreserve buoyancy provided by the freeboard as required by the previous Code of Safety for DynamicallySupported Craft (the DSC Code), adopted as IMO res. A.373(X).The HSC Code does not aim to cover requirements related to pollution prevention, and the MARPOLConvention has to be dealt with separately.1.2 General requirementsThe application of the provisions of this Code is subject to the following general requirements that:

.1 the Code will be applied in its entirety:

.2 the management of the company operating the craft exercises strict control over its operation andmaintenance by a quality management system *;

.3 the management ensures that only persons qualified to operate the specific type of craft used on theintended route are employed;

.4 the distances covered and the worst intended conditions in which operations are permitted will berestricted by the imposition of operational limits;

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

.6 adequate communications facilities, weather forecasts and maintenance facilities are available withinthe area of operation;

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

.8 areas of high fire risk such as machinery spaces and special category spaces are protected with fire-resistant materials and fire-extinguishing systems to ensure, as far as is practicable, containment andrapid extinguishing of fire;

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

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

.11 that no enclosed sleeping berths for passengers are provided;

.12 where the Administration has made a comprehensive review of the adequacy of the fire safetymeasures and evacuation procedures for the crew accommodation, sleeping berths for crew may bepermitted.

1.5.6 When a nominated surveyor or recognized organization determines that the condition of the craft or itsequipment does not correspond substantially with the particulars of the certificate or is such that the craft is notfit to operate without danger to the craft or persons on board, such surveyor or organization should immediatelyensure that corrective action is taken and should, in due course, notify the Administration. If such correctiveaction is not taken the certificate should be withdrawn and the Administration should be notified immediately;and, if the craft is in an area under the jurisdiction of another Government, the appropriate authorities of theport State should be notified immediately. When an officer of the Administration, a nominated surveyor orrecognized organization has notified the appropriate authorities of the port State, the Government of the portState concerned should give such officer, surveyor or organization any necessary assistance to carry out theirobligations under this section. When applicable, the Government of the port State concerned should ensurethat the craft should not continue to operate until it can do so without danger to the craft or the persons onboard.1.5.7 In every case, the Administration should fully guarantee the completeness and efficiency of the inspectionand survey, and should undertake to ensure the necessary arrangements to satisfy this obligation.1.6 Approvals

The owner of a craft should accept the obligation to supply sufficient information to enable the Administrationto fully assess the features of the design. It is strongly recommended that the owner and Administration and,where appropriate, the port State or States, commence discussions at the earliest possible stage so that theAdministration may fully evaluate the design in determining what additional or alternative requirements shouldbe applied to the craft to achieve the required level of safety.1.7 Maintenance of conditions after survey

1.7.1 The condition of the craft and its equipment should be maintained to conform with the provisions of thisCode to ensure that the craft in all respects will remain fit to operate without danger to the craft or the personson board.1.7.2 After any survey of the craft under 1.5 has been completed, no change should be made to structure,equipment, fittings, arrangements and materials covered by the survey, without the sanction of theAdministration.1.7.3 Whenever an accident occurs to a craft or a defect is discovered, either of which affects the safety of thecraft or the efficiency or completeness of structure, equipment, fittings, arrangements and materials, the personin charge or owner of the craft should report at the earliest opportunity to the Administration, the nominatedsurveyor or recognized organization responsible, who should cause investigations to be initiated to determinewhether a survey, as required by 1.5, is necessary. If the craft is in an area under the jurisdiction of anotherGovernment, the person in charge or the owner should also report immediately to the appropriate authoritiesof the port State and the nominated surveyor or recognized organization should ascertain that such a reporthas been made.1.8 High Speed Craft Safety Certificate

1.8.1 A certificate called a High Speed Craft Safety Certificate is issued after completion of an initial or renewalsurvey to a craft which complies with the requirements of the Code. The certificate should be issued orendorsed either by the Administration or by any person or organization recognized by it. In every case, thatAdministration assumes full responsibility for the certificate.1.8.2 A Contracting Government to the Convention may, at the request of the Administration, cause a craft tobe surveyed and, if satisfied that the requirements of the Code are complied with, should issue or authorize theissue of a certificate to the craft and, where appropriate, endorse or authorize the endorsement of a certificateon the craft in accordance with the Code. Any certificate so issued should contain a statement to the effect thatit has been issued at the request of the Government of the State the flag of which the craft is entitled to fly, andit should have the same force and receive the same recognition as a certificate issued under 1.8.1.1.8.3 The certificate should be that of the model given in annex 1 to the Code. If the language used is neitherEnglish nor French, the text should include a translation into one of these languages.

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 issued for a period specified by the Administrationwhich should not exceed five years.1.8.5 Notwithstanding the requirements of 1.8.4, when the renewal survey is completed within three monthsbefore the expiry date of the existing certificate, the new certificate should be valid from the date of completionof the renewal survey to a date not exceeding five years from the date of expiry of the existing certificate.1.8.6 When the renewal survey is completed after the expiry date of the existing certificate, the new certificateshould be valid from the date of completion of the renewal survey to a date not exceeding five years from thedate of expiry of the existing certificate.

DET NORSKE VERITAS


1.8.7 When the renewal survey is completed more than three months before the expiry date of the existingcertificate, the new certificate should be valid from the date of completion of the renewal survey to a date notexceeding five years from the date of 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 ofthe certificate beyond the expiry date to the maximum period specified in 1.8.4, provided that the surveys whena certificate is issued for a period of five years are carried out.1.8.9 If a renewal survey has been completed and a new certificate cannot be issued or placed on board the craftbefore the expiry date of the existing certificate, the person or organization authorized by the Administration mayendorse the existing certificate and such a certificate should be accepted as valid for a further period which shouldnot exceed 5 months from the expiry date.1.8.10 If a craft at the time when a certificate expires is not in the place in which it is to be surveyed, theAdministration may extend the period of validity of the certificate but this extension should be granted only forthe purpose of allowing the craft to proceed to the place in which it is to be surveyed, and then only in caseswhere it appears proper and reasonable to do so. No certificate should be extended for a period longer thanone month, and a craft to which an extension is granted should not, on its arrival in the place in which it is tobe surveyed, be entitled by virtue of such extension to leave that place without having a new certificate. Whenthe renewal survey is completed, the new certificate should be valid to a date not exceeding five years from thedate of expiry of the existing certificate before the extension was granted.1.8.11 In special circumstances, as determined by the Administration, a new certificate need not be dated fromthe date of expiry of the existing certificate as required by 1.8.6 or 1.8.10. In these circumstances, the newcertificate should be valid to a date not exceeding five years from the date of completion of the renewal survey.1.8.12 If a periodical survey is completed before the period specified in 1.5, then:

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

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

.3 the expiry date may remain unchanged provided one or more periodical surveys are carried out so thatthe maximum intervals between the surveys prescribed by 1.5.1.3 are not exceeded.

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

.1 if the relevant surveys are not completed within the periods specified in 7.5.1;

.2 if the certificate is not endorsed in accordance with 1.5.3; or

.3 upon transfer of the craft to the flag of another State. A new certificate should only be issued when theGovernment issuing the new certificate is fully satisfied that the craft is in compliance with therequirements of 1.7.1 and 1.7.2. In the case of a transfer between Governments that are ContractingGovernments to the Convention, if requested within three months after the transfer has taken place, theGovernment of the State whose flag the craft was formerly entitled to fly should, as soon as possible,transmit to the Administration a copy of the certificate 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 favour of 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 Permit to Operate High Speed Craft is issued andvalid in addition to the High Speed Craft Safety Certificate. Transit voyage without passengers or cargo maybe undertaken without the Permit to Operate High Speed Craft.1.9.2 The Permit to Operate High Speed Craft should be issued by the Administration to certify compliance with1.2.2 to 1.2.7 and stipulate conditions of the operation of the craft and drawn up on the basis of the informationcontained in the route operational manual specified in chapter 18 of this Code.

Guidance note:Chapter 18 covers operational requirements, which is currently not included in the HSLC rules.


1.9.3 Before issuing the Permit to Operate, the Administration should consult with each port State to obtaindetails of any operational conditions associated with operation of the craft in that State. Any such conditionsimposed should be shown by the Administration on the Permit to Operate and included in the route operationalmanual.1.9.4 A port State may inspect the craft and audit its documentation for the sole purpose of verifying itscompliance with the matters certified by and conditions associated with the Permit to Operate. Wheredeficiencies are shown by such an audit, the Permit to Operate ceases to be valid until such deficiencies arecorrected or otherwise resolved.

DET NORSKE VERITAS


1.9.5 The provisions of 1.8 should apply to the issue and the period of validity of the Permit to Operate HighSpeed Craft.1.9.6 The Permit to Operate High Speed Craft should be that of the model given in annex 2 to this Code. If thelanguage used is neither English nor French, the text should include a translation into one of these languages.

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


1.10 Control

The provisions of regulation I/19 of the Convention should be applied to include the Permit to Operate HighSpeed Craft in addition to the certificate issued under 1.8.1.11 Equivalents

1.11.1 Where this Code requires that a particular fitting, material, appliance or apparatus, or type thereof, shouldbe fitted or carried in a craft, or that any particular provision should be made, the Administration may allow anyother fitting, material, appliance or apparatus, or type thereof, to be fitted or carried, or any other provision tobe made in that craft, if it is satisfied by trial thereof or otherwise that such fitting, material, appliance orapparatus, or type thereof, or provision, is at least as effective as that required by this Code.1.11.2 Where compliance with any of the requirements of this Code would be impractical for the particulardesigns of the craft, the Administration may substitute those with alternative requirements provided thatequivalent safety is achieved. The Administration which allows any such substitution should communicate tothe Organization particulars of these substitutions and the reasons therefor, which the Organization shouldcirculate to its Member Governments for their information.1.12 Information to be made available

1.12.1 The Administration should ensure that the management of the company operating the craft has providedthe craft with adequate information and guidance in the form of manuals to enable the craft to be operated andmaintained safely. These manuals should include a route operational manual, craft operating manual,maintenance manual and servicing schedule. Such information should be updated as necessary.1.12.2 The manuals should contain at least the information specified in chapter 18 and should be in a languageunderstood by the crew. Where this language is not English, a translation into English should be provided of atleast the route operational manual and the craft operating manual.

Guidance note:Chapter 18 covers operational requirements, which is currently not included in the HSLC rules.


1.13 Further developments

1.13.1 It is recognized that there is much ongoing research and development in the design of high speed craftand that new types may emerge which have different geometry to that envisaged during the formulation of thisCode. It is important that this Code does not restrict this progress and the development of new designs.1.13.2 A design may be produced which cannot comply with the provisions of this Code. In such a case theAdministration should determine the extent to which the provisions of the Code are applicable to the designand, if necessary, develop additional or alternative requirements to provide an equivalent level of safety for thecraft.1.13.3 The foregoing should be considered by the Administration when assessing the granting of equivalentsunder the Code.1.14 Circulation of safety information

1.14.1 In the event that an Administration has cause to investigate an accident involving a craft to which thisCode applies, that Administration should provide a copy of the official report to the Organization, which willinvite Member States to note the existence of the report and to obtain a copy.1.14.2 In the event that operational experience reveals structural or equipment failures affecting the safety of adesign, craft owners should inform the Administration.1.15 Review of the Code

1.15.1 The Code should be reviewed by the Organization at intervals preferably not exceeding four years toconsider revision of existing requirements to take account of new developments in design and technology.1.15.2 Where a new development in design and technology has been found acceptable to an Administration,that Administration may submit particulars of such development to the Organization for consideration forincorporation into the Code during periodical review.

SECTION 3 FLAG ADMINISTRATION REQUIREMENTS

A. GeneralA 100 IMO HSC Code - General101 The IMO HSC Code has a number of requirements which are left to the Flag State Administration todecide upon with respect to the specific interpretation of the requirement. The Code text often uses theexpression that the requirement should be "to the satisfaction of the Administration".102 The goal for international regulations is to have as uniform requirements as possible. Most requirementswhich contain the expression "to the satisfaction of the Administration" have been removed from IMOdocuments as far as practicable.103 Those requirements which are dependant on local or domestic conditions are still up to theAdministration to decide.104 DNV aims at a uniform set of requirements both to be as transparent as possible and also to be specificin contractual and statutory matters. Consequently, a number of the "up to the Administration" requirements ofthe HSC Code has been interpreted by DNV.105 The cross references between the HSC Code and the DNV rules refer to all requirements in the HSCCode where the Flag or Port State is mentioned in connection with a requirement.106 The HSC Code paragraphs left to the Administration to decide, and the corresponding DNV paragraphwith comments are given in the following. HSC Code paragraphs are given by x.x.x and DNV paragraphs byPt.y Ch.y Sec.y.
