Thicker Insulation Costs More Than Space — It Costs Revenue: How VacuEco Supertech VPU Recovers an Entire Cargo Tank
Cutting insulation thickness by 60–120 mm to release hidden cargo volume on LNG and LPG carriers
For an LNG carrier, hull dimensions, tank capacity, and sailing efficiency determine overall economic value. Yet one factor is often overlooked: the LNG tank insulation system. Insulation not only blocks external heat and reduces boil-off gas (BOG) — it directly affects usable tank volume. With a fixed internal tank diameter, every 10 mm of insulation saved is magnified across the full tank circumference, releasing additional cargo volume on every voyage. For shipowners, more usable tank volume means more cargo per voyage, lower transport cost per unit, and better long-term operating returns.
