Units of capacity for the English Measurement System

I find the English Measurement System capacities being provided in liquid cubic feet confusing. In industry articles about LNG tankers capacity is typically provided in cubic meters for metric liquid volume, and sometimes in BCFe (billion cubic feet equivalent) for English. A typical 2017 built LNG tanker that can transit the newly enlarged Panama Canal holds about 3.5-3.7 BCFe. When I see that the Christophe de Margerie has a 6,100,000 cubic feet capacity, it is easy to mis-interpret that as 6.1 BCFe, which I think is much larger than it actually is? Perhaps both US gallons and BCFe could be provided instead of cubic feet. As a reader of the article both of those would be more useful than measuring liquid capacity in cubic feet. -- Gregfreemyer (talk) 14:38, 17 December 2017 (UTC)

Propulsion

The Reliquefaction section says "Normally an LNG tanker is powered by steam turbines with boilers" but the "inside of a LNG carrier" diagram shows a reciprocating internal combustion engine. So I'm left wondering which it is. Maybe it's normally steam turbines, and the diagram shows an abnormal type. Kendall-K1 (talk) 02:15, 2 April 2013 (UTC)

My understanding is steam turbine propulsion for LNG tankers lost favor in the early 2000's and by 2005 most new builds were dual fuel diesel electric. I'm not sure enough of that to adjust the main article. -- Gregfreemyer (talk) 15:09, 17 December 2017 (UTC)

New Building

Section currently gives me no sense of how long it takes to build these ships. What is the overall time from purchase order to delivery of a new ship? How many large carrier ships can be under construction simultaneously? How many (how long) will be needed to replace the now-doomed Nordstream 2 pipeline capacity?
