For effective ship manufacturing, a ship is divided into hundreds of properly sized blocks in the design stage. Each block is produced in its own manufacturing process, and subsequently the blocks are assembled into the body of a ship. Performance evaluation of the block manufacturing process (BMP) has been an important issue in the shipbuilding industry, since the BMP is related to overall shi...

The application of composite materials in shipbuilding provides undeniable advantages the mass characteristics structures. However, achievement these is associated with reasonable design methods for such article discusses features most commonly used standards and rules, compares results test calculations, gives recommendations improving Russian regulatory documents. task was set to create softw...

Alloy ASTM A710 (HSLA-80) is a co-precipitation hardened steel with a desirable combination of mechanical properties and weldability, making it an excellent candidate for use in structural applications such as bridges, shipbuilding, and pipelines. There have been extensive studies of the strengthening mechanisms, effect of heat treatment and continuous cooling, and kinetics of the precipitation...

In this paper one of the fundamental problems of Shipbuilding Industry known as block assignment problem is modeled and solved. The irregular shape of blocks and the inherent intractability of this problem is the primary motivation to use the interactive genetic algorithms with a specialized chromosome level “repair” operator. Without loss of generality, some domain knowledge has been incorpora...

Shipbuilding companies often suffer from long production cycles, low staff utilisation and an unbalanced line. To solve these problems, a lean shipbuilding regime is used which involves work breakdowns, plans virtual flow operations that combine with modern information management technology in shipbuilding. Production planning manages all the activities of facility. are achieved just-in-time th...

In this paper, some of the architectural and tracking aspects of the software engine used in our on-going MARIN (Mobile Augmented Reality Tool for Marine Industry) project are described. The purpose of the project is to construct an augmented reality tool for shipbuilding. The future target usages of the system vary from inspection to actually improving the efficiency of some of the repeating p...

Shipbuilding steels and alloys may be subjected to various types of corrosion damage when exposed sea water. For reliable long-term operation ships marine structures, despite the use protection, materials are chosen that, in addition required mechanical properties, have sufficient resistance ensure a given service life. Evaluation new for shipbuilding was made by carrying out mandatory delivery...

BACKGROUND The high mesothelioma incidence in Monfalcone, Italy, is mainly attributable to shipbuilding activity. Mesothelioma risk among shipyard workers in Monfalcone is poorly defined. MATERIALS AND METHODS Workers hired at the Monfalcone shipyards in the period 1950-1959 were identified by surveying shipyard roll. The list of the workers was coupled with the archive data of Monfalcone and...
