Abstract

Single Point Mooring atau SPM merupakan sarana bertambatnya kapal di laut, yang sekaligus berfungsi sebagai penyalur minyak dari atau ke kapal yang bertambat. Teknologi baru pada SPM berkembang seiring perkembangan teknologi eksplorasi minyak. Teknologi baru mengandung aspek inovatif yang belum diatur oleh standar yang ada, karena itu, tidak dapat dinilai melalui prosedur sertifikasi umum. Pengkajian perlu dilakukan untuk memastikan bahwa teknologi baru dapat diimplementasikan dengan aman dan dapat diandalkan. Proses pengkajian teknologi baru disebut Technology Qualification (TQ). Prosedur pengkajian teknologi baru pada SPM dikembangkan dari guidance yang diterbitkan oleh DNV, LR dan ABS. Proses pengkajian dilakukan dengan metode numerik dengan bantuan beberapa software komputer. Beberapa analisa yang dilakukan yaitu analisa motion response, analisa chain tension, analisa kekuatan struktur dan analisa stabilitas lambung SPM. Analisa dilakukan terkait penerapan bentuk lambung octagonal SPM yang merupakan teknologi baru. Aplikasi bentuk lambung octagonal SPM dapat diterima, karena telah memenuhi kriteria pengkajian teknologi yang diberikan. Dari hasil pengkajian diketahui bahwa, tension maksimum yang terjadi pada chain leg SPM adalah 157.725 ton, tidak melebihi breaking load dari chain yang digunakan. Tegangan maksimum yang terjadi pada struktur SPM adalah 205 MPa, tidak melebihi tegangan ijin dari material yang digunakan. Sedangkan berdasarkan analisa SPM memenuhi kriteria stabilitas, baik intact stability maupun damage syability. =============================================================================================== Single Point Mooring (SPM) is one of types mooring and oil transfer technology at the sea. New technology of SPM is evolving with the development of oil exploration technology. The new technology contains innovative aspects wich have not been regulated by existing standards, therefore, it is can not be assessed with common certification procedure. Assessment needs to be conducted to ensure that new technologies can be implemented safely and reliable. The assessment process of new technology called Technology Qualification (TQ). New technology qualification procedures of SPM is developed from guidance issued by DNV, LR and ABS. The qualification process carried out by numerical methods with the used of computer software. Several analyzes were performed, such as motion response, tension chain, structural strength and stability of SPM hull. The analysis were carried out related to the application of octagonal hull form SPM which is considered as new technology. Application of octagonal shape of hull on the SPM is acceptable, because it has met the criteria established technology qualification. From the results of the study is known that the maximum tension that occurs in SPM chain leg is 157 725 tons. The tension does not exceed the breaking load of the chain that is used. The maximum stress that occurs in the SPM structure is 205 MPa, do not exceed the allowable stress of the material used. Meanwhile, based on the stability analysis, stability of the new SPM still comply the stability criteria, either intact stability and damage stability.
