These guidelines were developed in 1998/99 for Exxon Chemical Europe Inc., Basic Chemicals Europe by Captain C. Allport of Standard Marine Services Limited and replace earlier guidance. They are based upon the report and advice from an LPG Measurement Survey conducted by Srini Sivaraman of ER&E in May/June 1997 and incorporate the earlier guidelines for Liquefied Gas Cargo Measurement and Calculation, produced in 1987 for Exxon Chemicals International by the Centre for Advanced Maritime Studies, Edinburgh. The earlier guidelines were adopted by Exxon Chemical International Inc. and approved by Regional Audit in 1988.
