Abstract
In an offshore plant, many modules and equipment are placed on the limited space called topside, so that the space should be used efficiently. Furthermore, a sufficient space between equipment should be provided for the operability, maintainability, and safety. To guarantee suitable arrangement design, there are many requirements to be considered such as international codes and standards, including owners own requirements. Also, the arrangement design of an offshore plant topside tends to rely on experts knowledge and experiences. In this study, an arrangement method of offshore plant topside based on the expert system and the optimization technique was proposed to obtain the optimal layout which satisfies many requirements as mentioned above. Proposed method consists of four component. First, an expert system that can systematically computerize experts knowledge and experiences, and can evaluate the feasibility of alternatives for the arrangement design of the offshore plant topside was proposed by expanding the previous study of authors for the arrangement design of a submarine. Second, an arrangement template model (ATM) was proposed to store various data on the arrangement design of the offshore plant topside. Third, an optimization method that can yield a better arrangement design was proposed by formulating a topside arrangement problem as optimization problem. Forth, user interface was developed for expert system and optimization. To evaluate the applicability of the proposed arrangement method, a prototype program was also developed here. Finally, this program was applied to a problem of a large FPSO topside. The results showed that the proposed method can be used to obtain the optimal arrangement of offshore plant topside.
