Abstract
The oil and gas service industry revenue is projected to rise to $350 billion in 2020, and a major part of such services belong to repair and maintenance (R&M) of the drilling rigs. Therefore, with regard to the number of jack-up rigs in Iran and the Persian Gulf, the R&M and improvement of these types of rigs become particularly important, especially due to the high lifespan of these rigs, which increases the time frequency of basic repairs. Nevertheless, Iran is suffering from lack of management and knowledge in the field of project resource management in this industry. Therefore, knowing the strategies and effective criteria for this industry is essential. In this paper, 15 criteria affecting the selection of R&M strategy were determined through interviews with experts, and the effect of each criterion on each alternative (seven strategies) was studied, and the most appropriate R&M strategy was then selected through analytic hierarchy process (AHP). The results show that the best strategy for Iran's entry into the R&M market is to perform all basic repairs of the rig, followed by license and joint venture. Finally, the best strategy was applied at R&M of Sina1 rig, comparing the results with those for Iranian rigs such as Modarres and Rajaei, the repairs of which were carried out in foreign yards, indicates the low cost of domestic repairs and the economic justification.
Highlights
IntroductionThe repair and maintenance (R&M) market will be better by the day due to the increased time frequency of basic repairs [1]
The Alternatives which are considered in this study to select the best repair and maintenance (R&M) strategies of drilling rigs are: Performing all major repairs of rig (A1); Performing repairs under the license of international companies (A2); R&M contracting through joint venture with foreign companies (A3); Providing technical, engineering, management, and software services (A4); Manufacturing and supplying components for repair of rigs (A5); Purchasing stock of foreign companies or their ownership (A6); Transferring all R&M services to foreign companies (A7); and Providing transport services to the yards in the area (A8)
It is clear that each strategy for entering the R&M market of drilling rigs has advantages and disadvantages
Summary
The R&M market will be better by the day due to the increased time frequency of basic repairs [1]. Due to the large part of the operations in the land workshop, the rig repairs often require a large workspace and guiding rails. The provision of the required infrastructure in the land is costly; so, it is suggested to use low-volume equipment and lower energy consumption [2]
