Shell reported this week to regulators that the floating roof of one of its API 650 tanks in Deer Park partially sank due to the heavy rainfall. Based on such issues, ...

Draining API 650 Storage Tanks of Oil
As expected, the Organization of the Petroleum Exporting Countries (OPEC) and some non-OPEC countries reached an agreement in 2016 to cut the production of crude oil to increase prices. This cut has ended the super contango in the oil market, and API 650 tanks are starting to be emptied to put the oil on the market. A contango is when the current price of a commodity does not reflect its actual value. This results in the future price of the commodity being higher than the spot price. A ...
Repurposing an API 650 Tank: Max Fill Height and API 653
API 650 tanks are commonly repurposed to store a different liquid than what intended when the tank was originally built.
