Absolutely. These ships have been in service for decades. I recently learned about CNG ships using compartments of coiled "tubing".
LOL! One of my coworkers played with those. Like I said, I didn’t deal with the ship side other than getting the stuff “to” them, but I do remember the designs were pretty cool. Big issue is that you need to have it segmented so they can pop off one section, and keep integrity on the others. So there are tons of gas meters, pop offs, back flows, etc.
I don’t know what they do now, but he said that they were investigating using stacks of tanks instead of a dedicated ship. The benefit was that older freight tankers could retrofitted, but the cost was higher because you needed specialized containers, and multiples of them them.
You know, I should call him. It has been a number of years since we talked and I bet he has some rather interesting insight into this.
