Over the years, DNV has created a series of internationally recognized standards, service specifications and recommended practices together with the pipeline industry.

Pipeline codes

Our first pipeline code was issued in 1976. It has achieved global recognition, winning prestigious industry awards and currently 65% of all new projects globally are designed to it.

Based on our project experience, research and joint industry development work, DNV issues a number of pipeline codes. These comprise service specifications, standards and recommended practices, and are highly regarded within the international pipeline community.

The pipeline standard, DNV-ST-F101 Submarine pipeline systems (previously named DNV-OS-F101), provides acceptance criteria and procedures for pipeline design, fabrication and installation. The standard applies modern limit-state-design principles with ‘safety classes’ linked to consequences of failure.

DNV's pipeline standard is complemented by several recommended practices (RPs), which give detailed advice on how to analyse specific technical aspects according to stated criteria:

Some of the above RPs were originally developed for offshore pipelines, but are also relevant for onshore pipelines, umbilicals, flexibles and power cables. In addition, DNV has released DNV-ST-F119 as a new standard for thermoplastic composite pipes (TCP).
