General Classification In accordance with 1-1-3/3 of the ABS Rules for Conditions of Classification (Part 1)@ the classification notationA1 Asphalt Carrier with Independent Tanks (temp??is to be assigned to vessels designed for carriage of asphalt solutions with maximum design cargo temperature of temp??in independent tanks (during loading@ steady state@ etc.)@ and built to the requirements of this Guide and other relevant sections of the ABS Rules for Building and Classing Steel Vessels (Steel Vessel Rules). In addition@ the classification notation SH@ SHCM is to be assigned to vessels having lengths of 150 m (492 ft) and above. As used in the Guide@ the term ??asphalt solutions?? refers to asphalt solutions listed in Appendix I to Annex I of MARPOL 1973 as modified by the 1978 and 1997 Protocols@ and having flash points above 60??(140??@ closed cup test. Optional Class Notation for Design Fatigue Life Vessels designed and built to the requirements in this Guide are intended to have a structural fatigue life of not less than 20 years. Where a vessel??s design calls for a fatigue life in excess of the minimum design fatigue life of 20 years@ the optional class notation FL (year) will be assigned at the request of the applicant. This optional notation is eligible provided the excess design fatigue life is verified to be in compliance with the criteria in Appendix 3 of the ABS Guide for Building and Classing Liquefied Gas Carriers with Independent Tanks (LGC Guide). The (year) refers to the fatigue life equal to 25 years or more (in 5-year increments) as specified by the applicant. The fatigue life will be identified in the Record by the notation FL (year) (e.g.@ FL(30) if the minimum design fatigue life assessed is 30 years). Only one design fatigue life value is published for the entire structural system. Where differing design fatigue life values are intended for different structural elements within the vessel@ the (year) refers to the least of the varying target lives. The ??design fatigue life?? refers to the target value set by the applicant@ not the value calculated in the analysis.
