Last week we retained Omega Squared consulting to do another vibration and noise evaluation on our tank farm vessels. The results point to one specific vessel on that emits a low ‘groan’ whenever gas is rushing into or out of the tank. This causes a bit of resonation and is the source of the particular sound. We’ve ordered a custom fitted ‘double septum’ blanket to cover the entire vessel. This blanket is also specifically designed to absorb the exact frequency that the vessel emits. We’ll update again when we’ve got it installed.
