Removing the requirement to fill the empty pipeline with water can significantly reduce cost for pipeline operators, although some additional work will be required to prove an equivalent safety level.
For example, the outcome of a workshop on dimensions including key industry players has now been built into the standard. With the updates, the djv-rp now gives requirements to when an Engineering Critical Assessment should be performed.

My Account Edit User. Calculation method EN Eurocode 8: Magazine Free Copy Request. The standard now reflects findings on selection of safety classes, limit state criteria, additional guidelines specific to PiP and code breaks. The joint industry projects presented the typical challenges that should be addressed in planning and design of marine operations and the common basis for installation design of pipelines, umbilicals and cables.
UK chemical engineer salary drops from Combined equipment EN Unfired pressure vessels – Part 3: For example, the dnv–rp of a workshop on dimensions including key industry players has now been built into the standard.

Click to watch our Webinar: This reliable and cost effective mechanical connection method is ideal where welded or hot-work options may be undesirable or not economically viable. The connectors are configured with a dual seal assembly allowing the integrity to be verified via seal verification ports.
Another modification to the standard expected to be well received by the industry is that the requirements for replacement of the system pressure test have become more flexible and do not rule out pipelines in shallower water. Probes EN Non destructive testing – Characterisation and verification of ultrasonic examination equipment- Part: New international standards for storage CCS and transport of carbon dioxide CO2 will be presented at a seminar Penetrant testing at temperatures lower than 10 degrees C ISO Welding and allied processes — Determination of hydrogen content in ferritic steel arc weld metal ISO Quality requirements for fusion welding of metallic materials — Part 2: Instruments EN Non destructive testing – Characterisation and verification of ultrasonic examination equipment- Part 2: 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.
An additional modification to the standard is that the requirements for replacement of the system pressure test have become more flexible and no longer rule out pipelines in shallower water.
The rigid pipeline criteria from this JIP is now captured in the new dnv-ep. The standard now reflects findings on selection of safety classes, limit state criteria, additional guidelines specific to PiP and code breaks. Design of structures for earthquake resistance EN Metallic products – Types of inspection documents EN Non destructive testing – Characterisation and verification of ultrasonic examination equipment- Part 1: Subsea Innovation said it has completed testing on its 10th pipeline repair clamp in the last 9 months.
STATS Group have received international certification for the design and manufacture of its mechanical connector range. The standard now gives requirements to when an Engineering Critical Assessment dvn-rp be performed, but points to the RP on how this may be done.

Metso delivers first 3D printed valves. The revision also takes into account the findings from two joint industry projects run outside DNV GL: Submission shall pass the double blind paper review first in order to be presented in the conference….
The verification ports provide an external pressure test facility allowing the seal between the pipe and the Connector to be tested upon activation, prior to re-commissioning the line.
The laboratories support the pipeline industry with material testing, corrosion testing, full scale testing, flow testing and failure analysis.

Another substantial change to the standards is the removal of the section on fracture assessment, which has been included in an updated revision of the recommended practice DNVGL-RP-F These maintenance-free connectors eliminate the need for time consuming, costly and potentially hazardous hot work.
Double block and bleed valves can f1133 fitted to the seal verification ports to allow periodic monitoring of integrity once installed.
The slipover design and mechanical locking assembly does not require specialist equipment for installation and does not introduce localised stress or yield to the host pipe material to provide leak-tight mechanical integrity.
