INSPECTION REQUIREMENTS FOR CARGO TANKS

摘要

PUCO requested the LOI to determine if the regulations require an annual pneumatic or hydrostatic pressure test given that visual inspection is not possible. This situation is spelled out in the regulations exactly: (d) External visual inspection and testing. The following applies to the external visual inspection and testing of cargo tanks: (1) Where insulation precludes a complete external visual inspection as required by paragraphs (d)(2) through (d)(6) of this section, the cargo tank also must be given an internal visual inspection in accordance with paragraph (e) of this section. If external visual inspection is precluded because any part of the cargo tank wall is externally lined, coated, or designed to prevent an external visual inspection, those areas of the cargo tank must be internally inspected. If internal visual inspection is precluded because the cargo tank is lined, coated, or designed so as to prevent access for internal inspection, the tank must be hydrostatically or pneumatically tested in accordance with paragraph (g)(1)(ⅳ) of this section. Those items able to be externally inspected must be externally inspected and noted in the inspection report.
