Promoting policy to involve plant EPC companies for package deal has been studied to acquire overseas energy resources. The effectiveness of the package deal with the plant EPC companies has not been successful because the participation of the plant EPC companies is very rare. It is difficult for the plant EPC companies to join the package deal due to the lack of the fully responsible organization to support the plant EPC companies participating in a package deal. The followings are suggested as the ways to promote the participation of the plant EPC companies for package deal in this study; 1) financial support of the government for plant EPC companies 2) political support of the government for plant EPC companies 3) specialization of the advanced countries for public-private cooperation.

In this study, the numerical study has been carried out to analyze the leakage in a steam turbine labyrinth seal. We modified tooth shape of the labyrinth seal and find out the difference of leakage in this study. Original model is straight labyrinth seal and its modified model is slanted labyrinth seal. The numerical analyses are implemented on two models. The numerical results show that each leakage of tooth shape are found to be 0.4781 kg/s and 0.4485 kg/s, respectively. The slanted labyrinth seal confines in a steam better than straight labyrinth seal. Since actual clearance of the stream function in the slant model is smaller than that of the straight model.

The capability of design and engineering of global EPC companies has long been equalized through past similar construction experiences. Among various key factors in the success of EPC project, the capability of engineering is considered to be the most important factor since the engineering is preceding activities of EPC contract. The failure of engineering may adversely affect the subsequent procurement & construction activities and in turn may cause cost overrun or schedule delay. Therefore, an EPC company needs to continue to improve the engineering capabilities for the success of project. The engineering capabilities can be further improved if the EPC company should prevent recurrence of similar design faults that were previously committed. This study is intended to present how to make the most of the failure examples from previous projects towards a success of project. Failure is but a stepping stone to success. The EPC company can obtain useful lessons from the analysis of past failure examples.
