FULL CONTAINMENT LNG TANKS – THE ECONOMICAL CHOICE

A look at the considerations for LNG storage, with American Tank & Vessel and Cashman Preload Cryogenics With global pressure on petroleum storage, it is as important as ever to make good, economic choices in LNG/NGL storage selection. Often, full containment storage systems can support better economics and similar schedules versus single containment or double containment systems. Each job and design case are unique, and the overall system needs to be designed for each project. However, on multiple occasions an outer concrete containment structure is a better economic choice and is quickly becoming the new standard. FEED STUDIES LEAD TO FULL CONTAINMENT The historical decisions, for outer concrete tanks and full containment, were supported by permitting, adjacent fire, local regulations and other design issues. Today, there is another list of reasons why full containment with an outer concrete tank should be considered for best practice and best economics. Over the last few years AT&V and its partners have led multiple projects from the front end engineering and design (FEED) study stage with single containment only to realise later that full containment had additional...
