Flexible Protection
Utilising polyurethane technology, we offer a wide range of protection products manufactured in-house. This product lineup includes, but is not limited to, duct cable protection, bend restrictors, mudmat, pipemat, Riser clamps and protection, piggy-back clamps, covers and spacers. We also provide options for cast iron cable protection and ballast.
While many products are available as standard, we also have the capability to design and manufacture products according to your specific requirements. Our commitment to quality is evident in our use of marine-grade polyurethane materials sourced exclusively from approved suppliers. We offer a wide range of polyurethane systems, ensuring both quality and cost-effective solutions based on your needs.
Our PU factory is qualified in accordance with API17L1, and we can supply qualified materials compliant with API17L1 standards.
Product overview
Bend Stiffeners
Ovun Bend Stiffeners are designed to add stiffness at the termination points of flexible pipes, power cables, umbilicals thus limiting bending stresses and curvature to an acceptable level.
Bend stiffeners are usually attached at either the topside or subsea connection.

Cast Iron Ballast
Ovun Cast Iron Ballast is designed to add weight to subsea cables as well as protect from abrasion and damage due to impact from dropped objects, rock dumping etc.
The ballast system stabilizes a cable laying on the seabed, while also working s as a bending restrictor.

Bend Restrictors
Ovun Bend Restrictors are designed to prevent cables, flexible pipelines, or umbilicals from overbending and buckling at the interface with a rigid structure.
The Bend Restrictor elements consists of 2 half shells made from a high durability rigid polyurethane, assembled with bolts and lock nuts.
We have developed standard Bend Restrictors for a wide range of common diameters, loads and MRBs. Custom designs with a wide range of features are provided to specific applications when required by clients.

Mudmat – Reinforced
MudMat is a heavy-duty polyurethane (PU) Subsea Protection & Support Mat developed for use both offshore and onshore. The mat can be utilised as subsea support, landing and positioning device or as seabed, pipeline and cable protection.
The reinforced version includes steel reinforcing to increase stiffness for high load applications.

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.
