Realistic, since high tensile steel has already been used to some extent in many cases. A 20% reduction in steel weight will give a reduction of ~9% in propulsion power requirements. Function of new material has high tensile strength make reduce profile to support ship structure. The structure support with material have specific value of “material” such as tensile, impact, etc. Ship structure depend on environment, and good. and the important is to ensure propeller sink bellow sea water. Removing 3000 tons of permanent ballast fromĪ PCTC make reduce propulsion power demand by 8.5% but to achieve the same stability will reduce the increasing the beam by 0.25 metres. Ship stability is dangerous if value of KG highest position, this position when ship nothing bring good, for minimal that problem we can use water ballast in bellow of deck and edge ship position. But the problem is limitation from deep in port handling and sea track. If we design ship have 10% large with others can give about 4-5% higher transport efficiency. But we can optimization wiht some parameter But in our design many parameter must our thought to get optimum design, for example resistance equivalent with fuel consumption, stability, and construction. We can image if big ship can brought many container once trip. In general, mode transportation that has huge efficient is ship with the others. This paper got from any source about ship design and Wartsila Catalog.
