Removing the requirement to fill the empty pipeline with water can significantly reduce cost for pipeline operators, according to a DNV GL statement, although some additional work will be required to prove an equivalent safety level. A pipeline example is used to illustrate and compare the results.

DNV Releases New Pipeline Standard | Rigzone

This higher utilisation was allowed, given that both a more stringent design approach as well as a more stringent pipe manufacture was achieved.

Over the years, DNV GL has created a series of internationally recognised standards, service dn and recommended practices together with the pipeline industry. In order to minimize the installation tension due to the hanged section, they are installed empty and therefore the external pressure is often the prime load parameter for the design. Metso delivers first 3D printed valves.

The standard now reflects findings on selection of safety classes, limit state criteria, additional guidelines specific to PiP and code breaks. These comprise service specifications, standards and recommended practices, and are highly regarded within the international pipeline community. Our first pipeline code was issued in It operates dn of a user’s location or IP address. Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors.
