Thermodynamics at Sea: Managing Cargo Pressure & Temp
The Physics of Boil-Off: Heat Transfer in Transit
At its core, the formation of boil-off gas (BOG) is a relentless battle against the laws of thermodynamics—a silent tug-of-war between the cryogenic cargo and the world around it. Even the most advanced insulation systems can’t completely halt the march of heat into a liquefied gas tank. Instead, they slow it down, buying time for the cargo to reach its destination before too much of it slips away as vapor. To understand why boil-off happens—and how to manage it—we need to dissect the forces at play: the sources of heat, the mechanics of phase change, and the stubborn physics that make evaporation inevitable.
