42、ding, transport, and discharge operations. Consequently, it is important to determine whether the vessels tanks, vessel lines, and the associated cargo-handling system are sufficiently clean so that the intended cargo will not be contaminated. Cargoes of crude oil, petroleum, and petrochemicals have
43、 varying tolerances regarding the extent to which they are affected by on board quantities or residues after tank cleaning operations. These guidelines for pre-loading inspection of a vessels cargo-handling system are intended to minimize the risk of contaminating the cargo to be loaded. For vegetab
44、le oils and fats, refer to FOSFA Qualifications and Operational Procedures for Ships Engaged in the Carriage of Oils and Fats in Bulk for Edible and Oleo-Chemical Use. Tank inspection activities performed on board a vessel shall be performed in the presence of, or with the express permission of, the
45、 vessels master, cargo officer, or other appropriate authority. For safety reasons, only appropriate and intrinsically safe equipment shall be used. 1 Guidelines for Pre-loading Inspection of Marine Vessel Cargo Tanks and Their Cargo-handling Systems 1 Scope These guidelines specify procedures for d
46、etermining 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
47、 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 exi
48、st when performing pre-loading tank inspections, this guideline is not intended to restrict the judgment of the person performing the inspection. 2 Normative References The following referenced documents are indispensable for the application of this document.
