36、ordance with 1-1-3/3 and 1-1-3/25, the classification notation null A1 Oil Carrier, SH, SHCM is to be assigned to vessels designed for the carriage of oil cargoes in bulk, and built to the requirements of this Chapter and other relevant sections of the Rules. As used in the Rules, the term oil refer

37、s to petroleum products having flash points at or below 60C (140F), closed cup test, and specific gravity of not over 1.05. Vessels intended to carry fuel oil having a flash point above 60C (140F), closed cup test, and to receive classification null A1 Fuel Oil Carrier, SH, SHCM are to comply with t

38、he requirements of this Chapter and other relevant sections of the Rules, with the exception that the requirements for cofferdams, gastight bulkheads and aluminum paint may be modified. 1.2 Optional Class Notation for Design Fatigue Life (2003) Vessels designed and built to the requirements in this

39、Chapter are intended to have a structural fatigue life of not less than 20 years. Where a vessels 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 i

40、s eligible, provided the excess design fatigue life is verified to be in compliance with the criteria in Appendix 1 of this Chapter, “Fatigue Strength Assessment of Tankers”. Only one design fatigue life value is published for the entire structural system. Where differing design fatigue life values

41、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. The notation FL (year) denotes that the design fatigue life

42、 assessed according to Appendix 1 of this Chapter is greater than the minimum design fatigue life of 20 years. 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 (y

43、ear); e.g., FL(30) if the minimum design fatigue life assessed is 30 years. 1.3 Application 1.3.1 Size and Proportion (1997) The requirements contained in this Chapter are applicable to double hull tankers intended for unrestricted service, having lengths of 150 meters (492 feet) or more, and having

44、 parameters within the range as specified in 3-2-1/1. 1.3.2 Vessel Types The equations and formulae for determining design load and strength requirements, as specified in Section 5C-1-3 and Section 5C-1-4, are applicable to double hull tankers. For mid-deck or single hull tankers, the parameters use

45、d in the equations are to be adjusted according to the structural configurations and loading patterns outlined in Appendix 5C-1-A3 or Appendix 5C-1-A4. The strength assessment procedures and the failure criteria, as specified in Section 5C-1-5, are applicable to all types of tankers. 14 ABSRULES FOR

46、 BUILDING AND CLASSING STEEL VESSELS .2017 Part 5C Specific Vessel Types Chapter 1 Vessels Intended to Carry Oil in Bulk (150 m (492 ft) or more in Length) Section 1 Introduction 5C-1-1 Double hull tanker is a tank vessel having full depth wing water ballast tanks or other non-cargo spaces, and full

47、 breadth double bottom water ballast tanks or other non-cargo spaces throughout the cargo area, intended to prevent or at least reduce the liquid cargo outflow in an accidental stranding or collision. The size and capacity of these wing/double bottom tanks or spaces are to comply with MARPOL 73/78 a

48、nd national Regulations, as applicable. Mid-deck tanker: Refer to 5C-1-A4/1.1, “Design Concepts”. Single hull tanker is a tank vessel that does not fit the above definitions of Double hull tanker or Mid-deck tanker. 1.3.3 Direct Calculations Direct calculations with respect to the determination of d

49、esign loads and the establishment of alternative strength criteria based on first principles will be accepted for consideration, provided that all the supporting data, analysis procedures and calculated results are fully documented and submitted for review. In this regard, due consideration is to be given to the environmental conditions, probability of occurrence, uncertainties in load and response predictions and reliability of the structure in service.
