Abstract Safety and reliability of the assets in the Oil and Gas sector is considered critical to maximize availability and minimize downtime in production and operations. The industry, due to ageing assets, are re-visiting the maintenance planning of critical equipment through Reliability-Centered Maintenance (RCM). The RCM process comprises of the hierarchical structuring of technical objects according to their functional locations and further dividing them into their maintainable items and components. Generally, a criticality matrix is developed that would identify the highly critical assets based on criteria such as cost, production, safety, and environment. The Failure Modes and Effects Analysis (FMEA) is then performed for the identified functions, functional failures, and likely failure modes of each component of the asset. The failure modes can be identified from first principles and historical failure data from the asset owner or databases such as the Offshore Reliability Database (OREDA). The failure modes, mechanisms and causes are defined in accordance with International Standards such as ISO14224. The failure characteristics such as the hidden or evident nature of the failure modes, along with the occurrence of the failure within the bathtub curve, would help in deciding the right maintenance strategies such as condition-based, fixed-time, fault-finding intervals, run to failure or redesign. The maintenance tasks are then developed as a mitigation against each failure mode. Efficient and effective asset management strategies are achieved through the allocation of resources such as the labor, tools and materials required to execute the maintenance task. The maintenance tasks are grouped together based on the maintenance time intervals and the resulting maintenance plans are fed into the Computerized Maintenance Management System (CMMS) to manage the maintenance process and track the implementation of the maintenance tasks on site. The maintenance time intervals are allocated mainly based on the current industrial practices and may be qualitative in nature. This paper aims to quantitatively determine the right maintenance intervals by analyzing the historical failure data and determining the Mean Time Between Failures (MTBF) and Mean Time to Repair (MTTR). Cost and reliability analysis of the maintenance scenarios based on best industry practices and statistical analysis is determined. This helps with the decision-making process by improving the maintenance task intervals based on planned and unplanned maintenance downtime. A case study of an asset from the Oil and Gas sector is provided for demonstrating the proposed approach.

Significance The July 19 law’s limiting of the right of national self-determination in Israel to the Jewish people has angered the Arab minority and provoked international criticism, including comparisons to South Africa’s apartheid-era legislation. Impacts Human rights risks may deter some investors, particularly for high-profile or large-scale projects such as in the oil and gas sector. Projects in towns and cities with large Arab populations such as Jerusalem, Haifa, Jaffa and Nazareth will face particular scrutiny. To ward off criticism, compliance with the UN Guiding Principles on Business and Human Rights will be increasingly important.

PurposeThe purpose of this paper is to investigate the performance of a turbine structure of the oil and gas Egyptian company in terms of reliability, mean time to failure (MTTF), mean time to repair (MTTR) and mean time between failures (MTBF) under fuzzy environment and working criteria. This paper examines the impact of the failure of various components on the complete turbine structure of the oil and gas system.Design/methodology/approachTo overcome the problem of uncertain behavior of available data for various components, the right triangular generalized fuzzy number (RTrGFN) is proposed to be taken into the account to express the uncertainty which attains some tolerance in data. Furthermore, reliability indices are calculated with the help of the Lambda Tau method and the arithmetic operations on right generalized triangular fuzzy numbers (RTrGFN).FindingsThis paper explores the reliability of a repairable 3 out of 4 structure of turbines and along with the other parameters namely MTTF, MTTR and MTBF; under a fuzzy environment. Failure rates and repair times are expected to be exponential. The ranking of components of the structure is being found to decide the priority for maintenance.Originality/valueThis paper investigates the performance of the system with different spread/tolerance like 15%, 25% and 50% of crisp data. It helps to predict realistic results in the range value. To enhance the system's performance, the most important item of the system requires greater attention. For this, the authors find the sensitive part by ranking. For ranking, an extended approach has been developed to find the sensitive unit of the system by using the right triangular generalized fuzzy number. This paper explores the most and least sensitive component of the system, which helps the maintenance department to plan the maintenance action.

So far, the engineering department has not implemented a good maintenance system. Therefore we need a maintenance schedule to meet the need for maintenance. The method for the analysis function is: reliability analysis and maintainability factor analysis. From the application of the reliability centered maintenance system approach, it is concluded that the critical components and the compilation of the failure modes and effect analysis tables. Whereas from the results of the reliability analysis in the form of the rate of damage, the average time between the damage and the maintainability factor analysis, it is concluded that the average corrective maintenance, the average prevention time, the average maintenance time, the average active maintenance time, the maintenance frequency and the time. the average down time of the lathe electrical system components. The results of the calculation of Mean Time Between Maintenance obtained maintenance intervals of lathe electrical system components every 223.1 hours, lathe erosion every 401.6 hours, fixed head of lathe every 502 hours, lathe head off every 669.3 hours and lathe chuck every 1004 hours. Need to get (preventive maintenance), namely daily maintenance, weekly maintenance and monthly maintenance. Pentingnya fungsi pemeliharaan dalam jurusan pemesinan merupakan hal yang tak terbantahkan. Dengan tidak disadari akan berdampak besar terhadap proses pembelajaran jika pemeliharaan tidak dilakukan seperti, operasi mesin yang tidak aman, kemacetan mesin, kerugian daya, berhentinya proses pembelajaran dan berbagai fungsi sarana lain yang tidak diketahui untuk masa yang lama. Jurusan pemesinan selama ini belum menerapkan suatu sistem pemeliharaan yang baik. Dimana saat ini masih menerapkan suatu pemeliharaan yang bersifat darurat atau perawatan yang dilakukan apabila ada kerusakan (corective maintenance). Oleh karena itu dibutuhkan suatu jadwal pemeliharaan dalam memenuhi kebutuhan akan suatu pemeliharaan. Metode yang digunakan dalam pembentukan jadwal tersebut adalah dengan menerapkan pendekatan sistim yaitu reliability centered maintenance. Dan juga menerapkan fungsi analisa yaitu : analisa reliability dan analisa maintainability faktor. Dari penerapan pendekatan sistem reliability centered maintenance disimpulkan komponen kritis dan penyusunan tabel failure modes and effect analisis. Sedangkan dari hasil analisis reliability disimpulkan berupa laju kerusakan, waktu rata – rata diantara kerusakan dan analisa maintainbility faktor disimpulkan berupa rata – rata pemeliharaan korektif, waktu rata – rata pencegahan, waktu rata – rata pemeliharaan, waktu rata – rata pemeliharaan aktif, frekuensi pemeliharaan dan waktu rata – rata down time dari komponen sistem kelistrikan mesin bubut. Dari hasil perhitungan Mean Time Between Maintenance (MTBM)  didapatkan interval pemeliharaan atau perawatan untuk komponen sistem kelistrikan mesin bubut setiap 223,1111 jam, eretan mesin bubut setiap 401,6 jam, kepala tetap mesin bubut setiap 502 jam, kepala lepas mesin bubut setiap 669,3333 jam dan chuck mesin bubut setiap 1004 jam.  Jika melihat dari interval perawatan dan pemeliharaan diatas maka mesin bubut  perlu mendapatkan perawatan berkala atau terencana (preventive maintenance), yaitu perawatan harian, perawatan mingguan dan perawatan bulanan.

 AbstractActually the existence of foreign investment in Indonesia is not new phenomenon, due to foreign investment exist since colonialism era.The existence of foreign investment is still continuing to Soeharto era until reformation era. Spirit of foreign investment in colonialism era, Soharto era, and reformation era are different. Foreign investment in colonialsm era just explore of nation asset and ignore of nation welfare, and this matter is different from the character of foreign investment in Soeharto era also reformation era. Eventhough the involvement of foreign investor have any benefits to the host country, but on the other hand foreign investment have business oriented only whether the investment is secure and may result of profit. Refer to The Law Number 25 Year of 2007 Concerning Investment (hereinafter called UUPM) can not be separated from various interest that become of politic background of the law, even the law tend to liberalism of investment. Liberalism in the investment sector particularly of foreign investment basically exist far from issuing of UUPM, and the spirit of liberalism also stipulate in several rules among others The Law Number 5 Year of 1999 Concerning Prohibitation of Anti Trust and Unfair Competition, The Law Number 22 Year of 2001 Concerning Oil and Gas, The Law Number 7 Year of 2004 Concerning Water Resource, and also The Law Number 30 Year of 2009 Concerning Electricity.   Many rules as mentioned above has liberalism character and also indicator opposite wit the right to manage of the state to nation asset that relate to public interest as stipulated in the Indonesia Constitution. Actually the issuing of UUPM in case of implementation of article 33 Indonesia Constitution (UUD NRI 1945). Due to opportunity by Government to foreign investment as stipulate by article 12 UUPM and also the existence of many rules as well as The Law Number 5 Year of 1999 Concerning Prohibitation of Anti Trust and Unfair Competition, The Law Number 22 Year of 2001 Concerning Oil and Gas, The Law Number 7 Year of 2004 Concerning Water Resource, and also The Law Number 30 Year of 2009 Concerning Electricity, so the foreign investment that relate to public service is more exist in Indonesia. The existence is reflected many foreign companies. Free of foreign investment relate to public service is opposite with spirit of article 33 Indonesia Constitution. Keywords: Foreign Investment, Right of  State, Article 33 Indonesia Consitution AbstrakEksistensi penanaman modal asing (investasi asing) di Indonesia sebenarnya bukan merupakan fenomena baru di Indonesia, mengingat modal asing telah hadir di Indonesia sejak zaman kolonial dahulu.   Eksistensi penanaman modal asing terus berlanjut pada era orde baru sampai dengan era reformasi. Tentunya semangat penanaman modal asing pada saat era kolonial, era orde baru, dan era reformasi adalah berbeda. Penanaman modal asing pada saat era kolonial memiliki karakter eksploitatif atas aset bangsa dan mengabaikan kesejahteraan rakyat, hal ini tentunya berbeda dengan karakter penanaman modal asing pada era orde baru, dan era reformasi. Sekalipun kehadiran investor membawa manfaat bagi negara penerima modal, di sisi lain investor yang hendak menanamkan modalnya juga tidak lepas dari orientasi bisnis (oriented business), apakah modal yang diinvestasikan aman dan bisa menghasilkan keuntungan. Melihat eksistensi Undang–Undang Nomor 25 Tahun 2007 tentang Penanaman Modal (UUPM) tidak dapat dilepaskan dari beragam kepentingan yang mendasari untuk diterbitkannya undang–undang tersebut, bahkan terdapat kecenderungan semangat dari UUPM lebih cenderung kepada liberalisasi investasi. Liberalisasi pada sektor investasi khususnya investasi asing pada dasarnya eksis jauh sebelum lahirnya UUPM ternyata juga tampak secara tersirat dalam beberapa peraturan perundang–undangan di Indonesia. Perundang–undangan tersebut antara lain Undang–Undang Nomor 5 Tahun 1999 tentang Larangan Praktek Monopoli dan Persaingan Usaha Tidak Sehat, Undang–Undang Nomor 22 Tahun 2001 tentang Minyak Dan Gas Bumi, Undang–Undang Nomor 7 Tahun 2004 tentang Sumber Daya Air, dan Undang–Undang Nomor 30 Tahun 2009 tentang Ketenagalistrikan.Banyaknya peraturan perundang–undangan yang berkarakter liberal sebagaimana diuraikan di atas mengindikasikan bahwa hak menguasai negara atas aset bangsa yang berkaitan dengan hajat hidup orang banyak sebagaimana diamahkan oleh Undang–Undang Dasar 1945 (Konstitusi) mulai “dikebiri” dengan adanya undang–undang yang tidak selaras semangatnya. Padahal, UUPM diterbitkan dalam kerangka mengimplementasikan amanat Pasal 33 Undang–Undang Dasar Negara Republik Indonesia Tahun 1945 (UUD NRI 1945). Dengan adanya peluang yang diberikan oleh pemerintah kepada investor asing sebagaimana yang diatur dalam Pasal 12 UUPM ditambah lagi dengan adanya Undang–Undang Nomor 5 Tahun 1999 tentang Larangan Praktek Monopoli dan Persaingan Usaha Tidak Sehat, Undang–Undang Nomor 22 Tahun 2001 tentang Minyak Dan Gas Bumi, Undang–Undang Nomor 7 Tahun 2004 tentang Sumber Daya Air, dan Undang–Undang Nomor 30 Tahun 2009 tentang Ketenagalistrikan, maka investasi asing yang berhubungan dengan cabang– cabang yang menguasai hajat hidup orang banyak semakin eksis di Indonesia. Terbukanya investasi asing atas cabang–cabang produksi yang menguasai hajat hidup orang banyak tentunya hal ini bertentangan dengan konsep hak menguasai negara sebagaimana diatur dalam Pasal 33 UUD NRI 1945. Kata Kunci: Investasi Asing, Hak Menguasai Negara, Pasal 33 UUD NRI Tahun          1945
