2、eagle.org for the consolidated version of the Guide for Compliance with the ILO Maritime Labour Convention, 2006 Title 3 Requirements, 2009, with all Notices and Corrigenda incorporated.) Notes - The date in the parentheses means the date that the Rule becomes effective for new construction based on
3、 the contract date for construction. (See 1-1-4/3.3 of the ABS Rules for Conditions of Classification (Part 1).) SECTION 1 GENERAL (Revise Subsection 1/3, as follows.) 3 Scope (15 October 2010) This Guide focuses on five (5) aspects of vessel design and layout that can be controlled, measured, and a
4、ssessed. These five (5) aspects are broken into two (2) major types in this Guide: accommodations design and characteristics of the ambient environment. Accommodations criteria pertain to dimensional or physical aspects of spaces/areas where seafarers work, eat, sleep, recreate, and conduct routine
5、activities. The criteria associated with the MLC-ACCOM notation is applicable only to accommodation spaces where seafarers sleep, rest, dine, and recreate. This Guide, particularly in Section 3, “Whole-body Vibration” and Section 4, “Noise”, provides additional guidance related to seafarer work spac
6、es. This guidance can be used if any voluntary ambient environmental testing is to be done in seafarer work spaces. This testing is recommended, but not required.

7、OLE-BODY VIBRATION 3 Terminology (15 October 2010) (Add new terms “Stationkeeping”, “Thruster Conditions”, and “Transit Conditions”, as follows.) Reference Calibration: Calibration of a measuring instrument conducted by an accredited Testing and Calibration Laboratory with traceability to a national
8、 or international standard. Stationkeeping: Maintaining a vessel in a position relative to other vessels or a fixed point. This may include the use of main engines and/or thrusters. Thruster Conditions: Those conditions when thrusters are used to maintain the vessels position and heading during stat
9、ionkeeping. Transit Conditions: Those conditions where the vessels primary form of propulsion is via main engine and propeller. This does not include occurrences such as vessel entry or departure from port or dock. Vibration: The variation with time of the magnitude of a quantity which is descriptiv
10、e of the motion or position of a mechanical system, when the magnitude is alternately greater and smaller than some average value. (Revise Section 3, Table 1, as follows.)

12、r each whole-body vibration measurement position during transit and, if applicable, stationkeeping/thruster conditions. Each whole-body vibration measurement sample shall be at least sixty (60) seconds in duration. Where significant frequency components exist in the range below two (2) Hz, measureme
13、nt duration of at least 120 seconds is required. In the case of high speed craft, each whole-body vibration measurement sample shall be at least 227 seconds in duration. The above measurement samples shall all be taken using the appropriate Type 1 or 2 instrumentation (ISO 8041: 2007), then frequenc
14、y weighted and analyzed in accordance with ISO 6954: 2000. It is desirable to employ equipment that records and stores acceleration time histories.

15、 Subparagraph 3/7.3.1, as follows:) 7.3.1 Power Output (15 October 2010) i) Transit: The propulsion machinery shall run at normal service speed and at no less than eighty (80) percent of the maximum continuous rating (MCR). ii) Stationkeeping: Stationkeeping devices (azimuth or tunnel thrusters auto
16、matic or manual) shall be in operation and run at a service speed sufficient to maintain position in sea conditions equal to or less than Sea State three. (Revise Subparagraph 3/7.3.2, as follows:) 7.3.2 Equipment Operation (15 October 2010) As appropriate for the mode of operation (transit or stati
17、onkeeping), all machinery essential for vessel operation shall operate under normal conditions throughout the measurement period. Heating, Ventilation, and Air Conditioning (HVAC) systems are to be running as for normal seagoing conditions during the whole-body vibration measurements. (Revise Subpar
18、agraph 3/7.3.4, as follows:) 7.3.4 Rudder Conditions (15 October 2010) The rudder angle shall be restricted to a range of 0 2. Minimal rudder action is desirable. During stationkeeping, measurements shall be taken while the vessel is maintaining a position relative to another vessel or fixed point (
19、e.g., offshore installation). (Revise Subparagraph 3/7.3.6, as follows:) 7.3.6 Loading Conditions (15 October 2010) The loading condition of a vessel shall be as close as possible to normal operating conditions. SECTION 4 NOISE 7 Test Requirements (Revise Paragraph 4/7.2, as follows:) 7.2 Data Acqui
20、sition and Instruments (15 October 2010) The integrating-averaging sound level meter shall meet the requirements for a Type 1 or 2 instrument specified in IEC 61672-1 (2002). For the MLC-ACCOM notation, a single sample of data shall be recorded for each noise measurement position during transit and,
21、 if applicable, stationkeeping/thruster conditions.
