Cable Protection Ducting – PP Duct
Ovun manufactures Subsea Cable Protection for abrasion- and dropped object and wear protection,
Our Cable Protection Ducting has been designed to fit a wide range of cable or umbilical diameters. Design life is minimum 25 years and the protection units are not influenced by varying water depths.
For extreme durability or when the PP cable protection is used in harsh environments, we can offer heavy-duty material with considerably better performance than the standard elastomer.
Cable protection is supplied with Smart Band reinforced bands and buckles as standard. Other band solutions may be used upon request, such as Super Duplex, Inconel or titanium.

PipeMat
PipeMat is a mat made of High Density Polyethylene pipes, and is a low-cost alternative to the MudMat. PipeMat may be used as subsea support, landing and positioning device or seabed/ pipeline/cable protection for light loads. The PipeMat is without sharp edges and rigid parts and is therefore a safe alternative to similar installation and protection products.
PipeMat can easily be rolled up for transport and storage.
