The growing need for energy (oil and gas) has led to offshore resource development. As a reflection of this trend, there have been many advances in the technologies used for the subsea production systems that make offshore resource development possible. As the technologies for subsea production systems continue to grow, a subsea X-mas tree, the core equipment in a subsea production system, is required to have more functions than before. Generally, these complex functions lead to a change in its configuration. Therefore, this paper investigates a change in a subsea X-mas tree system to enhance system understanding, and conducts a leakage path analysis of a subsea X-mas tree system. Utilizing the recent configuration of the subsea X-mas tree, an identification of the leakage path and a quantitative risk analysis for the leakage using an FTA (fault tree analysis) are conducted.

In modern society, the role of university becomes diversified and the concerns on building construction or landscape architecture considering beautiful landscape and scene are increasing caused by increasing interest on external environment of campus. But relative importance of concerns for the context of landscape architecture in campus is neglected rather than other facilities. So the landscape architecture service could not be conducted well. Therefore the computerization of system or management program will be needed for effective landscape architecture tree management and sufficiency of concerns on continuously increasing landscape architecture in campus. The computerization of landscape architecture tree management will be important roles not only to raise the efficiency of landscape architecture management and the view of outdoor environment but also to increase the competitive power of rapidly changing university environment and the quality of education.
