ConocoPhillips (COP) adalah perusahaan energi terintegrasi terbesar ketiga di Amerika Serikat berdasarkan kapitalisasi pasar, produksi dan cadangan minyak dan gas terbukti. COP merupakan perusahaan penyuling terbesar ke empat dan pemegang cadangan terbukti terbesar ketujuh dari perusahaan-perusahaan yang tidak dikuasai oleh pemerintah. Di Indonesia, wilayah produksi utama COPI Inc Ltd berada di daratan Sumatera Selatan dan di lepas pantai Laut Natuna Selatan. Pada tahun 2004 produksi dimulai di lapangan Belanak yang merupakan pengembangan terbesar di Blok B hingga saat ini. Produksi mengalir melalui fasilitas terapung untuk produksi dan penyimpanan (Floating Production Storage and Offloading � FPSO) Belanak, yang selain memiliki fasilitas pemprosesan hidrokarbon dan penyimpanan minyak, juga memiliki kilang gas untuk mengekstraksi Liquefied Petroleum Gas (LPG) dari aliran gas bumi. Minyak mentah diekspor dari FPSO Belanak melalui Oil Offloading Buoy (OOB) sedangkan gas alam dialirkan melalui jalur pipa ekspor ke Singapore dan Malaysia. Produk LPG berupa Butana dan Propana dialirkan ke LPG Floating Storage Offloading (FSO) Gas Concord yang merupakan fasilitas pendinginan, penyimpanan, dan bongkar muat LPG melalui pipa bawah laut yang dihubungkan dengan sebuah sistem tambat. Sistem tambat (mooring) merupakan komponen penting dalam operasi yang mempengaruhi ketersediaan dan produktifitas di FSO Gas Concord dalam mencapai kinerja operasi yang diharapkan. Penggunaan teknologi sistem tambat yang tepat pada FSO merupakan pilihan untuk dapat memberikan keunggulan kinerja operasi. Peralihan dari sistem tambat FSO Gas Concord Calm Buoy menjadi Turret perlu dilihat pengaruhnya terhadap kinerja operasi. Atas analisa yang telah dilakukan, diperoleh kesimpulan bahwa: Dengan perbedaan teknologi dari kedua sistem tambat berdampak pada operasional Gas Concord. Hal yang paling berkontribusi terhadap kinerja operasi adalah ketersediaan suplai listrik. Dan berdasarkan pembahasan menunjukkan bahwa dengan menggunakan teknologi Turret memberikan suplai listrik yang lebih stabil minim gangguan dibandingkan dengan menggunakan teknologi Turret pada aplikasi di LPG FSO Gas Concord. Berdasarkan data angka-angka indikator kinerja yang berlaku di ConocoPhillips Indonesia yaitu Direct Operating Efficiency, Equipment Utilization, dan Operation Downtime menunjukkan peningkatan pada periode Turret dibandingkan periode Calm Buoy. Dan operational availability sebagai kriteria kinerja peralatan antara penggunaan sistem tambat CALM Buoy dan Turret juga menunjukkan peningkatan. Dengan demikian berdasarkan tinjauan teknologi dan indikator kinerja tersebut dapat disimpulkan bahwa peralihan teknologi sistem tambat Calm Buoy menjadi Raised Turret mempengaruhi kinerja operasi pada LPG FSO Gas Concord.

ConocoPhillips (COP) is the third largest integrated energy company in the United States by market capitalization, production and proven reserves of oil and gas. COP is the company's fourth-largest refiner and the seventh largest holder of proven reserves of companies that are not controlled by the government. In Indonesia, the main production area of COPI Inc. Ltd. is located in South Sumatra mainland and in the South Natuna Sea offshore. In 2004 production started in the field Belanak which is the biggest development in Block B until today. Flowing through a floating production facility for the production and storage (Floating Production Storage and Offloading - FPSO) Belanak, which besides having a hydrocarbon processing facilities and oil storage, also has a gas refinery to extract Liquefied Petroleum Gas (LPG) from the natural gas stream. Crude oil exported from the FPSO Belanak through Oil Offloading Buoy (OOB) while natural gas flowed through the pipeline to export to Singapore and Malaysia. LPG products such as butane and propane flowed into LPG Floating Storage Offloading (FSO) Gas Concord which is a cooling facility, storage, and loading and unloading of LPG through a subsea pipeline which is connected to a mooring system. Mooring system (mooring) is an important component in operations that affect the availability and productivity in Concord Gas FSO in achieving the expected operating performance. The use of appropriate technology mooring system on the FSO is an option to be able to provide the advantages of operating performance. The transition from Concord Gas FSO mooring system becomes Calm Buoy Turret be seen influence on the operating performance. Above analysis that has been done, the conclusion that: With the technological differences of the two systems have an impact on the operational mooring Gas Concord. It is most contributing to the performance of the operation is the availability of electricity supply. And based on discussion shows that by using technology Turret provide a more stable power supply interruption minimal compared with the use of technology in applications Turret Gas LPG FSO Concord. Based on data from performance indicator figures prevailing in Indonesia, namely ConocoPhillips Direct Operating Efficiency, Equipment Utilization and Operation Downtime overall showed an increase in the period compared to the period Calm Buoy Turret. And operational availability as equipment performance criteria between the use of CALM Buoy mooring system and Turret also showed an increase. Thus based on the technology and performance indicators, we can conclude that the transition Calm Buoy mooring system technology into Raised Turret affect operating performance in the LPG FSO Gas Concord.
