In addition to the shown alternative configurations for MSB 234, Ovun also delivers parallel (Duo) and double parallel (Quad) MSB 234 configurations.

This doubles or quadruples the buoyancy lift possible within this product type.

Typically a (surface) buoy in Duo configurations can be configured to a buoyancy up to approx. 40 tonnes, and hence a Quad configuration up to 80 tonnes.

The Quad configuration can also be delivered with a platform (optional).
