(a) An IMO Certificate issued under the IMO Resolution A.328(IX),''Code for the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk, 1975'' is usually sufficient evidence of compliance with this part for the Coast Guard to endorse a foreign flag vessel's Certificate of Compliance with the name of each cargo in Table 4 (follows Sec. 154.1872) that is listed on the IMO Certificate, if the information listed in item 3 of the IMO Certificate shows that--
(1) The design ambient temperatures meet Sec. 154.174 and Sec. 154.176;
(2) The cargo tank design stress factors and resulting MARVS of independent tanks type B or C meet Sec. 154.447 or Sec. 154.450; and
(3) The cargo tank MARVS of a type IIPG ship meets Sec. 172.175(c) of this chapter.
(b) If a foreign flag existing gas vessel meets Sec. 154.12 (b), (c), or (d), the vessel's IMO Certificate issued under the IMO ``Code for Existing Ships Carrying Liquefied Gases in Bulk, 1975'' is usually sufficient evidence of compliance with the requirements of Sec. 154.12(e) for the Coast Guard to endorse the Certificate of Compliance with the name of each cargo in Table 4 (follows Sec. 154.1872) that is listed on the IMO Certificate; however if a foreign flag existing gas vessel does not meet Sec. 154.12 (b), (c), or (d), an IMO Certificate issued under the IMO ``Code for Existing Ships Carrying Liquefied Gases in Bulk, 1975'' is not acceptable evidence of compliance with the requirements of this part for the endorsement of a Certificate of Compliance.
