ABSTRACT:
Marine structures are provided that are constructed from ultra-high strength, low alloy steels containing less than 2.5 wt % nickel and having a tensile strength greater than 900 MPa (130 ksi). A primary benefit is that the marine structures of this invention have a cost per unit strength substantially lower than that of currently available marine structures.
