API MPMS 17.10.2:2016

This standard provides guidance to vessel and shore personnel regarding accepted methods for determining quantities of Liquefied Petroleum and Chemical Gas cargoes on board refrigerated and/or pressurized gas carriers. It includes recommended methods for measuring, sampling, documenting, and reporting quantities on board these vessels. Accounting for quantities on refrigerated and/or pressurized gas carriers requires some additional steps and care which may be contained in specific commercial agreements, operational guidelines or regulations. Other requirements should be discussed at the key meeting (pre-transfer conference), as detailed in API MPMS Chapter 17.1, or as noted in this section. All should be referred to and taken into account during the measurement process for these cargoes.
