Bibliography

Describes requirements for weldable structural steels to be used in the fabrication of fixed offshore structures in the form of plates up to and including 150 mm thick. Also describes sections up to 63 mm thick except for sections delivered in the as-rolled condition which are permitted up to 25 mm thick only.
