What insulation material is widely used in LNG membrane tanks?
Direct Answer
Option A: Reinforced Polyurethane Foam (R-PUF) and Plywood Boxes with Perlite
Membrane containment systems, such as those by GTT, utilize reinforced polyurethane foam (R-PUF) and plywood boxes to provide essential thermal insulation. This system maintains the cryogenic cargo temperature, minimizes boil-off gas, and protects the ship's inner hull structure from the extreme cold of the liquefied cargo.
