Sebagai salah satu negara anggota OPEC, di Indonesia banyak dilaksanakan proyek-proyek pembangunan fasilitas penunjang terhadap kegiatan pertambangan minyak dan gas bumi. Pengembangan fasilitas tersebut dimulai dari tahap perancangan engineering, fabrikasi & pengadaan, dan konstruksi & instalasi. Sebagai tahapan yang paling akhir dari sebuah pembangunan fasilitas, tahap konstruksi & instalasi memiliki resiko keterlambatan paling tinggi dalam pelaksanaannya. Hal ini dipengaruhi oleh besarnya keterkaitan pekerjaan dengan pihak diluar perusahaan. Kondisi ini mendorong penulis untuk dapat mengidentifikasi faktor-faktor dominan yang berpengaruh. Dengan teridentifikasinya faktor-faktor dominan tersebut dan dilakukannya langkahlangkah antisipasinya, diharapkan dapat mencegah keterlambatan pelaksanaan proyek konstruksi & instalasi tersebut......As one of OPEC’s member, there are so many facilities development projects to support oil & gas mining activities in Indonesia. The development project is started from engineering design phase, to procurement and fabrication phase, and ended by construction and installation phase. As the last phase, construction & installation, has more risks related to time performance during the execution. These things affected by big corelation between the contractor and other outside parties. Such condition motivate writer to identify the dominant factors. By identifying these factors and take responses on them, delays on construction and installation performance will be avoided.

Perkembangan teknologi bidang kelautan semakin pesat seiring dengan kebutuhan zaman. Aktivitas eksploitasi sektor migas sudah merambah pada wilayah Deep Water sampai Ultra Deep Water. Namun pada realitasnya Indonesia belum mampu berperan aktif dalam pengembangan teknologi Mobile Offshore Platform Unit yang biasa digunakan untuk eksploitasi migas pada wilayah diatas. Hal ini dapat dilihat dari jenis anjungan yang digunakan pada eksploitasi migas lepas pantai masih banyak menggunakan struktur fixed platform dan lokasi eksploitasi masih terbatas pada wilayah perairan dangkal. Padahal Indonesia memiliki luas wilayah laut yang cukup besar, penggarapan cadangan migas pada wilayah perairan laut dalam harus mulai dilakukan, seperti di perairan Laut Arafura blok Masela yang diprediksi memiliki potensi gas alam hingga 20 tcf (trilion cubic feet) dan cadangan minyak bumi sebesar 24,36 mmstb (million stock tank barrels). Pada penelitian ini dilakukan studi kasus perancangan sebuah anjungan semi-submersible yang berfungsi sebagai Production Platform Unit yang digunakan pada eksploitasi migas di blok Masela, Laut Arafura. Rancangan tersebut dilengkapi dengan sistem pemosisian dinamik (dynamic positioning system) yang diuji pada skala model. Hasil dari eksperimen pada model uji tersebut digunakan untuk mengetahui tingkat akurasi dari penerapan sistem kontrol posisi Inertial Measurement Unit dan sensor ultrasonik terhadap beban lingkungan.

Technology development in marine sector has a rapid development in line with the needs of the era. The exploitation activity of oil and gas sector has been expanded to the deep sea area until ultra deep sea area. Whereas in reality, Indonesia is unable to contribute actively in the technology development of Mobile Offshore Platform Unit which used for oil and gas exploitation in those area. It can be seen on the fact that the exploitation of offshore oil and gas still use fixed structure and the location of platform exploitation still limited to the shallow water areas. While Indonesia has a large sea area, the cultivation of oil and gas reserves in the sea area should begin to planned carefully, as in the Arafura Sea Masela block which was predicted have potential of natural gas reach out 20 tcf (trilion cubic feet), the petroleum reserves by 24, 36 MMSTB (million stock tank barrels). In this study, there is a study case of semi-submersible rig design that serves as a Production Platform unit used in oil and gas exploitation in the Masela Block, the Arafura Sea. The design is completed with a dynamic positioning system (DPS) which has been tested at scale models. Results of experiments on the test model is used to determine the accuracy of the application of a simple position control system that is using The Measurement Inertial Unit and ultrasonic sensors on the environment resistance.

Offshore safety management, second edition provides an experienced engineer's perspective on the new Safety and environmental system (SEMS) regulations for offshore oil and gas drilling, how they compare to prior regulations, and how to implement the new standards seamlessly and efficiently. The second edition is greatly expanded, with increased coverage of technical areas such as engineering standards and drilling, and procedural areas such as safety cases and formal safety assessments. The new material both complements the SEMS coverage and increases the book's relevance to a global audience. Following the explosion, fire, and sinking of the Deepwater Horizon floating drilling rig in April 2010, the Bureau of Ocean Energy Management, Regulations, and Enforcement (BOEMRE) issued many new regulations. One of them was the Safety and Environmental System rule, which is based on the American Petroleum Institute's SEMP recommended practice, finalized in April 2013. Author Ian Sutton explains the SEMS rule, and describes what must be done to achieve compliance. Each of the twelve elements of the SEMS rule (such as Management of change and safe work practices) is described in the book, and guidance is provided on how to meet BOEMRE requirements.
