Minimising Deformation in thin plate high strength Steel Ship Structure
Deformation of thin plate high strength steel structures on ships is a cause for concern from the perspective of aesthetics as well as functionality in some cases. The inherent properties of high strength thin steel plates make them vulnerable to deformation when welded as grillages to form critical ship structures. While welder skill is a key factor, proper sequence of welding, controlled welding etc can significantly reduce the deformations. However, every structure is unique in and tailoring the welding requirements is needed to ensure minimising the deformations. It is therefore proposed to develop a software based system that can determine an optimised welding and fitup solution for each case. The output can be provided along with the production drawings to facilitate due care during production. A suitable solution may be proposed.
