For safe storage of drilling riser buoyancy on deck, Ovun has developed stacking devices to minimize skidding and increase safety on board. We supply two types – one for the first (deck) layer and one for the following layers.

The products can be delivered for several dimensions of drill risers. The block has fixing points for connecting of wire or strap in order to fasten a sling to the steel pipe of the riser module if desired. The modules are of low weight for easy handling.

Following sizes are available:

54″ Duo & Quad

56″ Duo & Quad

58″ Duo & Quad
