Design and implementation of a measuring system for shipbuilding based on WinCE
The measurement in shipbuilding is an important task of improving the quality and efficiency. Precision industrial surveying and computer technology can be applied to embedded measurement systems, in which the convenient functions of coordinate data collection, assistant calculation and analysis are provided to test shipbuilding quality. In this paper, the process of system design and operation was described in detail, and then the key technologies involved were discussed.
3-D geometric modeler for rapid ship safety assessment
Abstract CAD systems are used broadly in the shipbuilding industry. CAD systems for naval architecture are a useful tool for hull form, internal arrangement and the structural design of ships. These systems require high precision and expertise for efficient use. Therefore, these systems are not appropriate in supporting emergency responses, which require rapid modeling even if it generates some errors. This paper describes a geometric modeler for rapid ship safety assessment. The modeler is developed based on the 3-D geometric modeling kernel ACIS. The definition of hull form, internal arrangement and major longitudinal structural members is a fundamental function of the modeler. The developed modeler is interfaced with other applications used for ship safety assessment such as hydrostatic calculation, ship motion analysis in wave condition, longitudinal strength analysis and so on. In addition, it can generate a new ship model by making variations in a previously defined ship model.
Design for Safety
Perhaps an appropriate starting point for a paper entitled ‘Design for Safety’ is to define what we mean by ‘design’ and to see how considerations of ‘safety’ are likely to affect this task. According to the STARTS Guide [STARTS 1987] the design process may be divided into four distinct activities: 
 
 
abstraction: the operation of generalising, of identifying the essentials; 
 
 
decomposition: the process of reducing an object into a number of simpler, smaller parts; analysis of interactions, interfaces and structures; modularization; 
 
 
elaboration: the operation of detailing, adding features; 
 
 
decision making: identification and selection of alternative strategies.
