Buckle by design
Lateral buckling of a hot subsea flowline

The case
8 km of insulated 12 in flowline, heated by up to 100 °C at 250 bar, would grow about 8 m if it were free. On a straight lay the buckles pick their own places, with compression up to 1.5 MN. With gentle planned curves every 2 km they form where they were invited, and compression stays near 0.8 MN.
