The permanent ballast density of PB380 can reach up to 6.0 tons/m3, which is pre mixed with heavy bone shaped materials,

After being pumped in, it will initially cure like a slurry for 4 days and completely cure for 28 days. Stabilize the center of gravity.

It will not move under harsh ocean conditions and will remain inside the cabin in case of structural damage,

Its inertness, combined with a pH value exceeding 10, can prevent bacterial growth and prevent corrosion of steel structures.

This permanent ballast is composed of a mixture of different heavy aggregates and complies with strict corrosion testing procedures.
