What Is DNV Type Approval?

May 13, 2021 Tim Schneebeck

DNV is a classification society that was created in 2013 after the merger of Det Norske Veritas (Norway) and Germanischer Lloyd (Germany). The company assesses ships and offshore structures for safety and performance and issues design and construction guidelines. DNV monitors compliance with issued regulations and assigns vessel classes to new constructions.  

The company’s internal research also allows it to assess and certify machines and products for suitability. The colloquial term for this is "type approval."

Certifications are especially important for electrical systems on ships since they ensure quality and adherence to standards. For this reason, igus® spent several years working with DNV to qualify and certify its electrical cables for use in e-chain® cable carriers on ships and offshore structures. 

This is not a certification for moving cables that simply bend; it is a certification for cables that continuously move inside its cable carriers. Cables in continuous motion require completely different construction and material designs. igus® is the only company in the world with type approval from a classification society for cables used in e-chains® on ships or offshore structures. The product range encompasses all common types, from control cables to fiber optic cables to motor cables.

Here's what this unique DNV type approval means for you:

– A facilitated selection of cables without additional approval effort

– An extremely high degree of reliability in the increasing number of automation processes on ships

– Possible cost reduction since most classification societies recognize each other’s approvals

– Greater flexibility thanks to a large selection of more than 300 different cable types with DNV type approval

– Very short delivery times since these types are available from stock with no minimum order
