● Tailor-made product

● Short series● All activities concentrated aroundone complicated and expensive product

● Different types of design activities(Hull, out-fitting machinery)

. Different types of production

. Heavy product requiring extensive areas,transportations and lifting

● Much work done out-doors. Steel is costwise almost 50 ‘%o of thetotal material
