Effect of long periods of corrosion on the fatigue lifetime of offshore mooring chain steel

Qvale, Paul; Nordhagen, Håkon Ottar; Ås, Sigmund Kyrre; Skallerud, Bjørn Helge (Peer reviewed; Journal article, 2022)

R4-grade mooring chain steel specimens were subjected to alternating phases of saltwater corrosion and air fatigue to replicate seasonal load variations on chains in service. No significant difference in fatigue lifetimes ...
A fast simulation method for thermal management in wire arc additive manufacturing repair of a thin-walled structure

Qvale, Paul; Njaastad, Eirik B; Bræin, Torgeir; Ren, Xiaobo (Peer reviewed; Journal article, 2024)

Ensuring first-time-right on-site repair of critical structures is a key challenge for additive manufacturing (AM)–based repair solutions. Fast thermal simulations are thus needed to plan efficient and error-free AM ...
