API MPMS Chapter 17.1

Encourages uniform inspection practices for marine petroleum cargo quantity and quality control.These guidelines specify the policy and minimum recommended practices for the manual and automatic measurement, sampling, and accounting for bulk quantities of crude oil (including spiked, blended, and reconstituted crude oil), petroleum products and chemicals that are transported on marine vessels. Activities described in these guidelines include actions by producers, buyers, sellers, terminal operators, vessel owners and their crews, customs authorities, independent inspectors, and other parties with an interest in measurements. Use also will simplify the making of agreements for transferring volumes of petroleum cargoes and will help ensure that the agreements can be clearly interpreted and executed between parties. Included in this text are sample forms designed to provide a standard comprehensive format to record and report essential data obtained during the marine cargo inspection procedure.
