The cargo containment of an LNG ship Moss type Spherical doesn't have a full Secondary barrier 🚧 and only a thick, self-supporting aluminium sphere that is carried by a cylindrical skirt at the equator. The containment system is based on the principle of Leak Before Fail .
This type of containment system is subjected to a thorough stress analysis and must include 1️⃣ fatigue life and 2️⃣ crack propagation analysis .
Because of these design factors , this type requires only a partial Secondary barrier 🚧, comprising a drip tray and a splash barrier.
