Minimize skidding and increase safety

For safe storage of drilling riser buoyancy on deck, PartnerPlast has developed stacking devices to minimize skidding and increase safety on board. Major drilling companies, such as Ocean Rig, Odfjell Drilling, Saipem, Seadrill and Stena Drilling, use the products.

We supply two types – one for first deck layer, and one for the following layers. Units 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 low weight for easy handling.
