Therefore, recommendations were made to investigate the condition of the unstable pipeline region. Are you an Engineering professional?
Case Study: Assessment of pipeline on-bottom stability to DNV-RP-E and DNV-RP-F
Area of interest Engineering Training. Defense manufacturing is all about project manufacturing and project accounting. It emphasises the following dnb aspects:. The benefits By verifying pipeline stability based on the as-built concrete coating thickness against the original stability design code, DNV-RP-E, it was possible to conservatively determine that one of the regions was stable.
It emphasises the following key aspects: This content is available to members only.

The RP is intended to serve owners, system integrators, rope manufacturers, manufacturers of load-bearing synthetic yarns dbv coating, and termination hardware products. This showed the region was still unstable, despite the reduction in conservatism between the design codes. Students Click Here Join Us! Click Here to join Eng-Tips and talk with other members!

Lifting lines are used for the installation of subsea infrastructure, where the offshore fibre rope performs as an integral part of a lifting appliance and where no xnv can be seen in isolation.
New DNV GL RP on offshore fibre ropes
These include mooring systems, lifting slings, and deepwater deployment and recovery systems for subsea infrastructure. Offshore Fibre Rope should be analysed on the basis of amount of load-bearing material in the cross section, and the characteristics of the material used.
By further attempting to reduce conservatism through DNV-RP-F and an OrcaFlex model, it was found that the second region remained unstable under the three hour storm conditions.
Based on the concrete coating thickness recorded in the final survey report, vnv regions one 3km and another 5km region of the pipeline were found to be unstable. Register now while it’s still free! By joining you are opting in to receive e-mail.

The strength and endurance of synthetic rope, which is fundamentally different to the strength and endurance of steel-wire rope on the basis that mechanisms are different. The on-bottom stability analysis was performed according to the simplified stability analysis method outlined in DNV-FP-E ‘On-Bottom Stability Design of Submarine Pipelines’, the same methodology used in the original design.
The design calculations showed that the worst case environmental loading was the hundred year wave and then year current combination. Download Now Defense manufacturing is all about project manufacturing and project accounting. The solution The on-bottom stability analysis was performed according to the simplified stability analysis method outlined in DNV-FP-E ‘On-Bottom Stability Design of Submarine Pipelines’, the same methodology used in the original design.
The offshore oil and gas industry uses synthetic fibre ropes across various mission-critical activities where performance and reliability are key concerns. Thank you for helping keep Eng-Tips Forums free from inappropriate posts.
