1、 ABS GUIDE FOR BUILDING AND CLASSING HIGH SPEED CRAFT . 2001 1 GUIDE FOR BUILDING AND CLASSING HIGH SPEED CRAFT OCTOBER 2001 NOTICE NO. 3 July 2007 The following Rule Changes were approved by the ABS Rules Committee on 7 June 2007 and become EFFECTIVE AS OF 1 JULY 2007. (See http:/www.eagle.org/rule
2、s/downloads.html for the consolidated version of the Guide for Building and Classing High Speed Craft, October 2001, with all Notices and Corrigenda incorporated.)

PART 3 HULL CONSTRUCTION AND EQUIPMENT SECTION 3 SUBDIVISION AND STABILITY (Delete last sentence and Note in Subsection 3/3.7, to read as follows.) 3/3.7 Onboard Computers for Stability Calculations (1 July 2007) The use of onboard computers for s
4、tability calculations is not a requirement of class. However, if stability software is installed onboard craft contracted on or after 1 July 2005, it should cover all stability requirements applicable to the vessel and is to be approved by the Bureau for compliance with the requirements of Appendix

6、UIDE FOR BUILDING AND CLASSING HIGH SPEED CRAFT . 2001 PART 3 HULL CONSTRUCTION AND EQUIPMENT APPENDIX D ONBOARD COMPUTERS FOR STABILITY CALCULATIONS (1 July 2007) (Revise Appendix 3/D, specifically Table 3/D.1 and 3D/11.1, as follows.) 3/D.1 General 3/D.1.1 Scope The scope of stability calculation
7、software is to be in accordance with the stability information as approved by the flag Administration or the Bureau on behalf of the flag Administration. The software is at least to include all information and perform all calculations or checks as necessary to ensure compliance with the applicable s
8、tability requirements. Approved stability software is not a substitute for the approved stability information, and is used as a supplement to the approved stability information to facilitate stability calculations. 3/D.1.3 Design The input/output information is to be easily comparable with approved
9、stability information so as to avoid confusion and possible misinterpretation by the operator relative to the approved stability information. An operation manual is to be provided for the onboard computer stability software. The language in which the stability information is displayed and printed ou
10、t as well as the operation manual is written is to be the same as used in the crafts approved stability information. The primary language is to be English. The onboard computer for stability calculations is craft specific equipment and the results of the calculations are only applicable to the craft
11、 for which it has been approved. In case of modifications implying changes in the main data or internal arrangement of the craft, the specific approval of any original stability calculation software is no longer valid. The software is to be modified accordingly and reapproved. 3/D.3 Calculation Syst
12、ems This Appendix covers either system, a passive system that requires manual data entry or an active system, which replaces the manual with the automatic entry with sensors reading and entering the contents of tanks, etc., provided the active system is in the off-line operation mode. However, an in
13、tegrated system, which controls or initiates actions based on the sensor-supplied inputs is not within the scope of this Appendix. 3/D.5 Types of Stability Systems Three types of calculations performed by stability software are acceptable depending upon a crafts stability requirements: Type 1 Softwa
14、re calculating intact stability only (for craft not required to meet a damage stability criterion) Type 2 Software calculating intact stability and checking damage stability on basis of a limit curve or previously approved loading conditions Type 3 Software calculating intact stability and damage st

17、s loaded within the approval limits. The following parameters are to be presented for a given loading condition: Deadweight data Lightship data Trim Draft at the draft marks and perpendiculars Summary of loading condition displacement, VCG, LCG and, if applicable, TCG Downflooding angle and correspo
18、nding downflooding opening Compliance with stability criteria: Listing of all calculated stability criteria, the limit values, the obtained values and the conclusions (criteria fulfilled or not fulfilled) 3/D.7.3 Direct Damage Stability Calculations If direct damage stability calculations are perfor
19、med, the relevant damage cases according to the applicable rules are to be pre-defined for automatic check of a given loading condition. 3/D.7.5 Warning A clear warning is to be given on screen and in hard copy printout if any of the loading limitations are not complied with. 3/D.7.7 Data Printout T
20、he data are to be presented on screen and in hard copy printout in a clear unambiguous manner. 3/D.7.9 Date and Time The date and time of a saved calculation are to be part of the screen display and hard copy printout. 3/D.7.11 Information of Program Each hard copy printout is to include identificat
21、ion of the calculation program with version number. 3/D.7.13 Units Units of measurement are to be clearly identified and used consistently within a loading calculation. 3/D.9 Acceptable Toleranaces Depending on the type and scope of programs, the acceptable tolerances are to be determined differentl
22、y, according to 3/D.9.1 or 3/D.9.3. In general, deviation from these tolerances is not to be accepted unless a satisfactory explanation for the difference is submitted for review and the same is satisfactorily confirmed by the Bureau that there would be no adverse effect on the safety of the craft.
23、Examples of pre-programmed input data include the following: Hydrostatic data: Displacement, LCB, LCF, VCB, KMt and MCT vs. draft Stability data: KN or MS values at appropriate heel/trim angles vs. displacement, stability limits. Compartment data: Volume, LCG, VCG, TCG and FSM heeling moments vs. le
