New DNV GL RP on offshore fibre ropes
Dhv 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 Eng-Tips staff will check this out and take appropriate action. This content is available to members only. That’s right, but some data in the version are not dhv and I think I will need to go back to the version: Promoting, selling, recruiting, coursework and thesis posting is forbidden.
Lifting lines are used for the installation of subsea infrastructure, where the offshore fibre rope performs as dhv integral part of a lifting appliance and where no function can be seen in isolation. Please sign in or become a member for free.
Case Study: Assessment of pipeline on-bottom stability to DNV-RP-E and DNV-RP-F

The as-built concrete coating thickness stated in the final survey report differed from the thickness given in the coating specification, therefore a re-assessment of stability was required.
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. It emphasises the following key aspects: By further attempting dng reduce conservatism through DNV-RP-F and an OrcaFlex model, it was found that the second region remained unstable under gp three hour storm conditions.

DNVGL-RP-E RP Design, testing and analysis of offshore fibre ropes – DNV GL
Hello you guys, I would like to know what are the differences between the two recommanded practices of DNV: The offshore oil and gas industry uses synthetic fibre ropes across various mission-critical activities where performance and reliability are key concerns.
Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. 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.
The design calculations showed that the worst case environmental loading was the hundred year wave and then year current combination. Join your peers on the Internet’s largest technical engineering professional community.

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. For the 3km region, it was found that the as-laid water depth was greater than that used in the design. For the remaining unstable 5km region, the stability analysis was re-assessed using the generalised lateral stability and absolute lateral stability methods outlined in DNV-RP-F Defense manufacturing is all about project manufacturing and project accounting.
Therefore, recommendations were made to investigate the condition of the unstable pipeline region.
To further reduce conservatism, an OrcaFlex analysis was performed by modelling a 1km section e3005 the pipeline and applying the hundred year significant wave and ten year current using an irregular wave analysis JONSWAP wave spectrumwhich simulated a three hour storm.
