TRENDS IN THE STEELS USED IN MERCHANT SHIPBUILDING

With the increase in the size of modern merchant vessels, as well as changes in design and increased plate thicknesses, there has been a growing interest in the use of higher strength steels for ship construction. The history of hull steel specifications following the advent of welded construction is discussed, together with present American Bureau of Shipping requirements for both ordinary and higher strength steels. Some precautions that are considered particularly necessary when welding on higher strength steels are also presented. Since mobile offshore drilling units are now being classed by the Bureau, the owners and designers of such structures may find the discussions included in this paper of interest.
