RE: Kraken's production & FCF matters16 Jun 2019 12:18
Hi Londoner7
Are two parameters that ultimately limit storage on a tanker... First is Capacity, this is in Cubic Metres (m3), the second is deadweight usually in metric tons.
For Atalandi = Capacity of volume (Cubic (98%)) = 120324m3 and summer deadweight (colder water is more bouyant) of 105306MT.
The volume is static 6.29 barrels = 1m3, weight is variable and dependent on the weight/API Gravity of the Crude, i.e. Kraken Crude is 14API, so is some 15% heavier than 30API brent for the same m3 volume, this is where volume capacity is reduced, as the weight of the crude at max volume exceeds the deadweight, therefore max capacity has to be reduced.

It can become further compicated with ballast and compartmentalisation etc, so is always best guess, a good indicator is AK offloads at around 20k barrels per hour.
Hope this helps a bit... MO
