List of main engine fuel consumption breakdowns, one per report. Each breakdown lists, for every fuel consumed by the main engine during the reporting period, the amount consumed in metric tons (mt) and optionally that fuel's lower calorific value (LCV). Dual-fuel engines can report multiple fuels (e.g. boil-off gas plus pilot fuel) in a single breakdown. Unlike me_fo_consumption, which is a daily rate (mt/day), amounts are absolute totals for the reporting period, so they depend on the period's length. When provided, this field takes precedence over the deprecated me_fo_consumption, me_fuel_type, me_lcv, me_gas_consumption, me_gas_type and me_gas_lcv fields. Null means no breakdown was reported.
