CHANGES

General

The Executive Committee approved this chapter in November 2011.The rule changes come into force as described below.Text affected by the main rule changes in this edition is highlighted in red colour. However, where the changesinvolve a whole chapter, section or sub-section, only the title may be in red colour.

Main changes coming into force 1 July 2012

• GeneralThe tentative rules for Service Craft published in January 2011 are extensively updated with this revision andissued as revised tentative rules from January 2012.A key feature of the tentative rules within Pt.5 Ch.9 were the safety principles of the HSC Code and how thesewere interpreted and applied to service craft having size and operational restrictions as defined in Pt.5 Ch.9Sec.1. Whilst the safety principles are still reflected through the technical requirements of this Chapter, thereferences to the HSC Code including the tables previously listed in Pt.5 Ch.9 Sec.1 B100 are consideredsuperfluous to this set of rules and have therefore been removed. The principle applied as a basis in developing the new requirements for traditionally statutory disciplines is thatthese craft fall outside conventional IMO and statutory regimes. The requirements are therefore tailored to thesize and type of craft to achieve the same safety level as a conventional vessel.

• Sec.1 General— The title of the Chapter has been changed from “Tentative Rules for Domestic Service Craft” to “Tentative

Rules for Service Craft Carrying up to 12 Passengers”. Operational areas will be dependent on flag andport state acceptance

— Introduced limitation to total no. of persons onboard (12 passengers plus the number of crew required bythe flag Administration for safe manning)

— The definition of “12 workers” is modified to “12 workers or passengers”— Added a reference to Pt.1 Ch.1 Sec.2 B800 that represents an option for craft subject to national regulations— Service restriction for R1, winter zone, is increased from 125 to 150 nautical miles.

• Sec.2 Stability, Water- and Weathertight Integrity— Damage stability requirements are updated with the following changes:

— Limited damages to only one hull at the time for multihull crafts, except for the most forwardcompartments

— In case of damage to more than one compartment, relaxations in stability criteria for survival andfloatability are introduced

— Introduce a guidance note with an explanation on what is considered to be a reasonable definition ofpositive stability.

• Sec.3 Structure and Equipment— Special requirements to windows are removed implying that unmodified main class requirements apply

Clarification of acceleration factor fg is made by referencing Passenger notation— Design load for bow strength in way of docking is increased

• Sec.4 Arrangement— Requirement for Type Approved (TA) passenger seats on high speed craft is introduced.— Requirement for arrangement of galley and toilet is introduced.

• Sec.5 Control and Monitoring Systems— Reference to main class Pt.4 is now removed and the section now includes all relevant control and

monitoring system requirements.

• Sec.6 Anchoring and Mooring Equipment— Clarified certification requirements for anchoring equipment

requirements— Added requirement for no deep-fat frying equipment or open flame appliances to be installed onboard— Clarified certification requirements for the fixed fire-fighting system— Added requirement for main fire pump to be installed in a space fitted with fixed fire fighting system


Rules for High Speed, Light Craft and Naval Surface Craft, January 2012Pt.5 Ch.9 Changes –

— Added requirement for sprinkler system to be fitted in accommodation spaces for craft constructed of fibrecomposite materials

— Added requirement for a fireman's axe to be provided.

• Sec.8 Life Saving Appliances— Reference to main class Pt.3 Ch.8 is removed and the section now includes all relevant life saving appliance

requirements— Added requirements for rescue arrangements to recover a helpless person from the water— Removed requirement for the craft to carry personal protective equipment for all persons onboard; for the

workers/passengers this is assumed part of the work equipment— Added requirements for certification of life saving appliances

• Sec.9 Machinery— Removed requirement for 2 separate engine rooms with watertight subdivision— Requirements for engine control systems are now covered in Sec.5— Removed requirement for planned maintenance system— Requirements to certification of components and systems required in the main rules are removed except for

drivers, which are required to be Type Approved.

• Sec.10 Piping Systems (new section)— Requirements for bilge systems introduced

• Sec.11 (previously 10) Electrical System— Corrected references and clarified requirements.

• Sec.12 (previously 11) Safety of Navigation— Previous Sec.11 is split into 2 sections, one for safety of navigation and one for communication equipment— Reference to main class Pt.4 Ch.11-12 is removed and Section now includes all relevant safety of

navigation requirements— Added requirement for segregation of bridge from the space where the other persons are located along with

adjustable lighting on the bridge— Added requirement for craft to comply with COLREG 1972— Added minimum carriage requirements for navigation equipment including certification requirements for

such— Introduced specific requirements for visibility from bridge, including ability to observe berthing and

embarkation operations.

• Sec.13 Communication Equipment (new section)— Reference to main class Pt.4 Ch.11-12 is removed and Section now includes all relevant communication

equipment requirements— Added minimum carriage requirements for radio equipment including certification requirements for such.

SECTION 16 NOISE AND VIBRATION

A. General

A 100 Introduction

101 This section provides requirements to noise and vibration for service craft, aiming to limit exposurelevels to those acceptable for health and safety as specified in national and international standards.

A 200 References

201 Vibration is defined as structural motion in the frequency range 1 to 100 Hz.

202 Noise is defined as audible air pressure fluctuations generated by ship machinery, systems or structure,i.e. in the frequency range 20 to 20 000 Hz. Basic noise quantity and units are defined in ISO 31/VII.

203 Reference is made to national and international standards on noise criteria related to hearing damage andspeech intelligibility for safety reasons.

204 The standards shown below contain provisions which are referred to in this text or have been used by theSociety as basis when developing the rules:

— IMO Resolution A. 468 (XII), “Code of Noise Levels on Board Ships”— EU Directive 2003/10/EF.

B. Vibration

B 100 Local Vibrations

101 Vibrations in the hull structural elements are not considered in relation to the requirements for scantlingsgiven in the rules. It is however assumed that special investigations are made to avoid harmful vibrations,causing structural failures, malfunction of machinery and instruments or annoyance to crew and passengers/workers.

C. Noise

C 100 General

101 Compliance with the rules shall be verified through measurements. The measurements and reportingshall be carried out according to the procedures described in ISO 2923. The instrumentation to be used for themeasurements shall comply with the requirements given in ISO 2923.

102 A test program shall be approved prior to the measurements. The test program is at least to include thefollowing information:

— specification of measuring locations— required operating conditions for machinery— instrumentation to be used.

103 During the tests, generally the power output on the propulsion machinery shall correspond to at least 85%of maximum continuous power available. All other machinery shall be run under normal operating conditionsduring the tests. Air-conditioning supply and ventilation shall be run at normal full capacity during the tests.

C 200 Noise Criteria

201 The following upper acceptable noise limits apply:

Guidance note:1) IMO Resolution A.468 (XII) defines protection against risk of noise-induced hearing loss by specifying an upperlimit of 90 dB(A) for continuously manned working spaces, including machinery spaces. Besides, it is specified thatpersonnel entering spaces with noise levels greater than 85 dB(A) are required to wear ear protection. The 85 dB(A)limit is in accordance with the EU Directive 2003/10/EF on noise, Article 3, specified as daily noise exposure limitcalled “upper exposure action value” for 8-hours exposure.

— Machinery spaces, continuously manned1 90 dB(A)— Machinery spaces, not continuously manned2 110 dB(A)— Wheelhouse/navigation position 75 dB(A)



2) For machinery spaces with noise levels of above 110 dB(A), as well as requirements for acceptable ear protectorsand marking with warning signs, reference is made to IMO Resolution A.468(XII).
