The paper presents a view on selected problems concerning application of steel sandwich panels to marine structures. Such problems connected with specificity of thin-skin laserwelded structure are varying in topics beginning from micro-scale properties of laser-welded T-joint through the joining of sandwich structures together up to connection and integration of such structures with a classical single-skin structure.

Ship designing is a complex process, as the ship itself is a complex, technical multi-level object which operates in the air/water boundary environment and is exposed to the action of many different external and internal factors resulting from the adopted technical solutions, type of operation, and environmental conditions. A traditional ship design process consists of a series of subsequent multistage iterations, which gradually increase the design identification level. The paper presents problems related to the design of a small untypical vessel with the aid of variant methodology making use of optimisation algorithms. The computer-aided design methodology has been developed which does not need permanent reference to already built real ships and empirical-statistical relations. Possibilities were indicated for integrating together early design stages, and parallel designing of hull shape and parameters.

Dynamic development in practically all fields of science and engineering has not passed over shipbuilding . In last years , engineers got to their use computer software which makes it possible to perform strength and hydrodynamic calculations as well as to visualize design projects in 3 D space [1][2][3][4]. At their disposal they have full spectrum of modern solutions associated with the use of advanced materials and technologies [5][6][7]. More and more attention is also paid to impact onto the natural environment [8,9]
