3 Pt Vol 1 II Seagoing Ships Rules for Hull - August 2018 Section 2 Material B. Hull Structural Steel for Plates and Sections 3.4 Material selection for structural members which are exposed to low temperatures The material selection for structural members, which are continuously exposed to temperatures below 0 C, e.g. in or adjacent to refrigerated cargo holds, is governed by the design temperature of the structural members. The design temperature is the temperature determined by means of a temperature distribution calculation taking into account the design environmental temperatures. The design environmental temperatures for unrestricted service are: air sea water + 50 oo C C For ships intended to operate permanently in areas with low air temperatures (below and including - 20 (), e.g. regular service during winter seasons to Arctic or Anta rctic waters, the materials in exposed structures are to be selected based on the design temperature to, to be taken as defined in Materials in the various members above the lowest ballast waterline (BWL} exposed to air are not to be of lower grades than those corresponding to classes I, II and Ill, as given in Table , depending on the categories of structural members (Secondary, Primary and Special). For non-exposed structures (except as ind icated in Note 6 of Table 2.11 ) and structures below the lowest ballast waterline, see 3.2 and 3.3. (IACS UR S6.2) The material grade requirements for h u 11 member of each material class depending on thickness and design temperature are defined in Table For design temperatures to< - 55 C, materials are to be specially considered.
