Lateral buckling

Pipeline lateral (snake) buckling — DNV-RP-F110

Ask Deckhand to check a line for lateral (snake) buckling under high pressure and temperature, to DNV-RP-F110.

Run it on Open Deck

What you can ask it to do

  • Screen a line's susceptibility to global lateral (snake) buckling under HP/HT.
  • Estimate buckle spacing and the feed-in into a buckle.
  • Flag where mitigation (sleepers, buoyancy, snaking) is needed.

Questions

What is lateral buckling?

A high-pressure/high-temperature line wants to expand; where it is unrestrained on the seabed it relieves that load by snaking sideways into lateral buckles. DNV-RP-F110 governs the global-buckling design.

What does Deckhand return?

A susceptibility screen, an estimate of buckle spacing and feed-in, and a flag where mitigation is needed.
