1、 ABS RULES FOR BUILDING AND CLASSING STEEL VESSELS UNDER 90 METERS (295 FEET) IN LENGTH . 2006 1 RULES FOR BUILDING AND CLASSING STEEL VESSELS UNDER 90 METERS (295 FEET) IN LENGTH 2006 NOTICE NO. 4 July 2007 The following Rule Changes were approved by the ABS Rules Committee on 7 June 2007 and becom
2、e EFFECTIVE AS OF 1 JULY 2007*. (See http:/www.eagle.org/rules/downloads.html for the consolidated version of the Rules for Building and Classing Steel Vessels Under 90 meters (295 feet) in Length 2006, with all Notices and Corrigenda incorporated.) Notes * Except the change to 3-6-1/1.1.1, which is
3、 effective as of 1 July 2006 (based on the “keel laying” date or similar stage of construction) in line with the 2003 Amendments to SOLAS 1974, Chapter V, Reg. 2.4 Resolution MSC 142(77). - The date in the parentheses means the date that the Rule becomes effective for new construction based on the c

However, if stability software is installed onboar
6、d vessels 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 3-3-A2, “Onboard Computers for Stability Calculations”.

8、LL CONSTRUCTION AND EQUIPMENT CHAPTER 3 SUBDIVISION AND STABILITY APPENDIX 2 ONBOARD COMPUTERS FOR STABILITY CALCULATIONS (1 July 2007) (Revise Appendix 3-3-A2, specifically 3-3-A2/Table 1 and 3-3-A2/11.1, as follows.) 1 General 1.1 Scope The scope of stability calculation software is to be in accor
9、dance 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 stability requirements. App
10、roved 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. 1.3 Design The input/output information is to be easily comparable with approved stability information so as to
11、 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 out as well as the operation man
12、ual is written is to be the same as used in the vessels approved stability information. The primary language is to be English. The onboard computer for stability calculations is vessel specific equipment and the results of the calculations are only applicable to the vessel for which it has been appr
13、oved. In case of modifications implying changes in the main data or internal arrangement of the vessel, the specific approval of any original stability calculation software is no longer valid. The software is to be modified accordingly and reapproved. 3 Calculation Systems This Appendix covers eithe
14、r 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 integrated system, which control
15、s or initiates actions based on the sensor-supplied inputs is not within the scope of this Appendix.

18、pproved loading conditions Type 3 Software calculating intact stability and damage stability by direct application of preprogrammed damage cases for each loading condition (for some tankers etc.) 7 Functional Requirements 7.1 Calculation Program The calculation program is to present relevant paramet
19、ers of each loading condition in order to assist the Master in his judgment on whether the vessel is 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

21、ed) 7.3 Direct Damage Stability Calculations If direct damage stability calculations are performed, the relevant damage cases according to the applicable rules are to be pre-defined for automatic check of a given loading condition. 7.5 Warning A clear warning is to be given on screen and in hard cop
22、y printout if any of the loading limitations are not complied with. 7.7 Data Printout The data are to be presented on screen and in hard copy printout in a clear unambiguous manner. 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
