One of the biggest breakthroughs in sheet steel technology has been the development of high strength TMCP (Thermo-Mechanically Controlled Processed) steels. This type of steel sheet requires no preheating for welding and offers tight dimensional tolerances. It also increased the stringency of quality control of the plates prior to shipment. This particular breakthrough affected shipbuilding in many ways.
Shipbuilding has traditionally used structural plates to make hulls. The more modern steel offers significantly higher tensile strength, making them better suited for efficiently building larger ships. Not only did it speed up the shipbuilding process, but it also offers corrosion resistance which has been shown to be particularly beneficial for tankers.
Another advantage of this new type of steel plate is that the tanks are significantly lighter. During the design phase, some ships choose to maintain their normal weight while increasing their capacity. This offers significant opportunities to save on fuel consumption and reduce CO2 emissions. It also allows more goods to be shipped at one time, reducing costs, overheads and CO2 emissions.
Recently, more attention has been drawn to the safety and durability of ships in order to improve the environmental protection of the surrounding waters. This is one of the main reasons for recent breakthroughs in steel plate technology. Since the new plates are more corrosion resistant and lighter, many ships feature double hulls to prevent spills and leaks.
The new steel plates also eliminate the need for preheating during welding. This not only reduces the manufacturing cost by almost 30%, but also makes it easier to repair welds on site. As a result, the overall welding costs are lower and the time to manufacture a vessel is significantly reduced. In some cases, the total construction time can be reduced by 10%. This is particularly important because more importance is placed on safety at work and the reduction of working hours in welding.
By reducing manufacturing and labor costs, new plate technology offers many opportunities for cost reduction and control. This allows many fleets to increase the number of ships they operate, allowing more cargo to move around the world.
Overall, recent breakthroughs in sheet steel technology have affected shipbuilding at all levels. Not only has it made it possible to create lighter vessels in a shorter period of time, but it also offers opportunities to save on fuel consumption, control costs and reduce manpower.
