The results of mooring analysis of semisubmersible platform Scarabeo 7 according to the rules of two classification societies Amencan Petroleum Institute (API) and Det Norske Ventas (DN'I9 are presented In this paper The rules of those two classification societies are more often used in mooring analysis so the research goal was the comparison of obtained results according to API and OW criteria During mooring of an offshore object the main criteria have to be satisfied maximum displacement of the object which is restricted in order to avoid damage or breaking of riser and maximum tension in mooring line which is determined by safety factor as a ratio between the maximum force on the mooring line and the breaking force defined by the manufacturer Mooring analysis for operative condition has shown that given mooring system fully satisfies criteria during extreme weather conditions for one year return period For the case of non-operative conditions when the riser is still suspended to the well opening it was necessary to apply milder weather condition from those for 10 years return period 20% milder for API analysis and 25% milder for DNV analysis The mooring analysis was performed according two criteria maximum displacements and safety factors.

Strong competition and continuously changing market demands require constant change and improvements of a company's business. For production companies, it is very important to keep their production processes efficient by constantly improving them. In this paper the production management process approach is presented, as well as the fundamentals of Lean production. Value stream mapping has proved as one of the efficient tools for the analysis of production. Application of this tool for the analysis of waste in production process is presented in the case study.

Information and communication technologies have a central role in the manufacturing system integration process. In this paper, a conceptual framework for the integration of available software applications is presented. Analysis of Croatian industrial enterprises is used to create a feasible computer aided process planning model. The suggested model uses the built-in ability of installed software for sharing information derived from processes with which they are connected. Information is then used for generating the optimal process plan for the current surroundings in the central CAPP module. Using the presented conceptual framework, modular CAPP solutions are created and customized to fit the needs of different manufacturing enterprises, taking into consideration the implementation costs and time.
