Questions

What is upheaval buckling?

A buried high-temperature line at a vertical imperfection (an overbend) can push up through its cover; the design provides enough download — soil cover or rock dump — to hold it down. DNV-RP-F110 governs it.

What does Deckhand return?

An upheaval susceptibility screen and the required cover/download to restrain the line, flagging where rock dump is needed.
