Traditional structural design work involves repeated modeling, which is a tedious and time-consuming activity. To solve such problems, optimization of structural elements by using the UC ratio along with grouping is proposed. In the design of the offshore floating platform, optimization methods find out minimum weight solutions for the structure. However, due to the high diversity of profiles cost raises a lot. By doing the optimization in a grouping by UC ratio technique provides the unique optimal solution. The current study proposes an approach for reliability-based optimal design of FPSO structure. The current study comments on the optimized design of Topside FPSO structural assembly for various load conditions like Production tank pressure loads, Equipment loads, Piping loads, Electrical and Instrumentation load, girder deformation loads, Wind load, etc. Both Normal Operating and Extreme Operating conditions are taken by considering the effects of hull flexibility along with wind and motion-induced accelerations. The analysis and design optimization are performed in the STAAD Pro tool by selecting the least weight as an objective function while obeying the design constraints as per API standards. Optimization performed based upon Utility Check ratio in STAAD Pro tool. With analysis models constructed as described above, module primary structure design can be iteratively “unity-check-optimized”. By implication given method, optimized member unity checks (UCs) translate into optimized weight and hence cost optimization.

“…On reusing with the same function (i.e. direct reuse, refurbishment or remanufacturing) only a paper by Kaczmarek et al [34] present structural modularization for providing the possibility to reuse and recombine modules. Further actions could be derived when looking at repair, as indicated by Mishnaevsky [16].…”

To become the first climate-neutral continent by 2050, the EU is committing to ambitious targets such as reducing greenhouse gas emissions by at least 55% by 2030 (compared to 1990) and increasing the share of renewable energies in the EU energy mix to 45% by 2030. To meet these targets, the wind industry has to grow significantly while ensuring enough resources across the supply chains to scale the wind energy market and by striving to reduce its already shallow environmental impact. As material extraction and the production of wind turbines cause the most emissions, costs and risks on the scarcity of resources, the implementation of a circular economy could support the wind industry in meeting the EU target and improving its sustainability and resilience. However, the circular economy is a complex concept, and it can be challenging to translate it into precise action points, objectives and measurements. To clarify how a circular economy can support the wind industry, this paper takes the example of wind turbine blades, and it establishes a structured overview of research results and industrial initiatives aiming at implementing circularity for improving sustainability and resilience. The overview is used to investigate if objectives and clear actions are stated and how those differ between research and industry. By identifying gaps, future research and industry initiatives can be directed towards closing the bigger picture. The results show that many initiatives are ongoing, but only some circular strategies are comprehensively investigated, and clear objectives and measurements often remain to be included. The industry and research progressed the furthest on recycling. Future research and industry activities should further follow the path of closing the loop but need to also concentrate on reducing material use, extending the lifetime of blades and enabling a second lifecycle of blades.

“…Fujita et al (1999) share the opinion that the benefits of modularization fall into economy of scale. Kaczmarek et al (2016) have employed modularity as a mean to develop wind turbine rotor blades that are suitable to be produced in series, reducing product variety and design effort.…”

The importance of expanding a company's variety of products is easily observed in competitive markets, where a greater variety means a greater chance of meeting specific consumer needs. On the other hand, a larger product list implies the need for better variety management. In this article, we study how two companies deal with variety management during product development, in order to identify the factors and variables linked to their success. Three axes are observed to be central to effective variety management: variety, flexibility and integration. Furthermore, technical variables were also identified that enable a company to manipulate such axes. For each variable, levels of maturity are established that enabled the identification of how those companies perform their variety management. As result, a tool is delivered that can evaluate an organization's maturity level regarding variety management. The proposed tool is also capable of performing competitive benchmarks between different organizations.
