We estimate the volume each mining vessel can hold as 2100 m 3 (; 29.3 m × 8.1 m × 7 m). A sand density of 1600 kg m −3 is used to convert this volume into a tonnage applying a compaction factor of 0.5 to account for the space left between grains due to the unconsolidated nature of the sand being dredged.
