这些指南规定了确定海上船舶的货舱和相关货物装卸系统处于适当清洁状态以接收预期货物的程序。这适用于原油、石油产品和石化货物的装载。装载前检查的范围将根据待装载货物的性质而有所不同。这些指南建议对某些一般类型的货物应进行的检查范围，以及可用于报告储罐检查结果的格式示例。 由于在进行预装载罐检查时可能存在各种各样的情况，本指南无意限制检查人员的判断。

These guidelines specify procedures for determining that the cargo tanks and associated cargo-handling system of marine vessels are in a suitably clean condition to receive the intended cargo. This applies to the loading of crude oil, petroleum products, and petrochemical cargoes. The extent of pre-loading inspection will vary depending on the nature of the cargo to be loaded. These guidelines recommend the extent of inspection that should be instituted for certain general types of cargoes and an example of a format that may be used for reporting the findings of tank inspections. Because of the wide variety of conditions that may exist when performing pre-loading tank inspections, this guideline is not intended to restrict the judgment of the person performing the inspection.
