A floating warehouse so vast you could park it and call it real estate

means A large ship, truck, or aircraft built to carry liquids or gases in bulk, especially oil or fuel.

from Built straight from "tank," the storage vessel, plus the agent-suffix "-er" that turns a thing into a thing-that-does. "Tank" itself arrived in English via Portuguese "tanque" (a pond or reservoir), possibly tracing back to an Indian word for a cistern — picked up by English speakers in India. The shipping sense bloomed in the late 19th and early 20th centuries when oil started moving by sea, and a vessel that was essentially a hull full of tanks became, simply, a tanker.

sheer scale
Largest were longer than the Empire State is tall
slow stop
Needs miles and minutes to fully halt
crew count
Often just twenty people run the whole behemoth
too big
Some couldn't fit through Suez or English Channel
single hull
Banned after spills birthed the double-hull mandate
for instance
