...Yasuhisa Okumoto A ship hull block is generally composed of skin plates, longitudinals, and transverse webs as a grillage structure, and longitudinals and transverse webs are joined by a fillet weld on a skin plate panel. Then much labor time is necessary for this welding work because many welding...

... of prismatic hull blocks are given along with an analysis of grillages as typical parts of prismatic hull blocks. A model for marking the block parts and a diagram showing the flexible self-acting positioning of grillage elements during assembly are presented. The kinetic demands with necessary information...
