Perairan Indonesia yang sangat bervariasi kedalaman lautnya serta terhubung ke jalur sungai-sungai besar yang masuk hingga pedalaman merupakan suatu pertimbangan pemilihan tipe kapal sarat rendah. Seiring dengan itu peraturan keselamatan kapal semakin ketat merupakan tantangan dalam perancangan dan sistim operasional kapal. Karakteristik lengan stabilitas pada kapal sarat rendah yang berbeda pada kapal umumnya seperti yang disyaratkan dalam kriteria kestabilan minimum yang dikeluarkan oleh International Maritime Organization (IMO) Resolusi A.749(18) menjadikan kapal sarat rendah perlu kajian tersendiri. Dari hasil kajian dan uji model didapatkan bahwa untuk kapal sarat rendah (B/T ³ 4) pada prediksi roll dalam weather criterion direkomendasikan untuk adanya koreksi nilai N dari sebelumnya yang dipakai yaitu 0.02 menjadi 0.035, dengan nilai tersebut menunjukkan hasil prediksi maksimum roll yang realistik bagi kapal sarat rendah. Hal ini merupakan masukkan dalam penyusunan aturan keselamatan kapal sarat rendah.","PeriodicalId":263381,"journal":{"name":"Wave: Jurnal Ilmiah Teknologi Maritim","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126448809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In designing positional mooring systems for floating offshore units, systematic analyses must be performed to predict tension levels in the mooring lines and offsets of the floating unit under extreme and ambient service conditions, in order to ensure the mooring arrangement provides a level of safety acceptable to the industry. In order to derive environmental loads pertinent to the location of operation, environmental data should be made available comprising of long and short term current, wind and wave characteristic data specific to the site of operation. Based on LR FOIFL Rules, the performance of positional mooring systems is assessed on the basis of sets of site specific extreme and ambient (or fatigue) environmental conditions. Class rules require consideration of extreme conditions with recurrence period of 100 years (e.g. combination of 100 year waves + 100 year wind + 10 year current).In the process of designing positional mooring systems of FPSOs, designers may start from quasi-static analysis at preliminary design stage, and then investigate various combinations of extreme conditions in the dynamic analysis for a more rigorous approach during the final design stage.The outcomes of the analyses have to be compared against industry standards such as the LR FOIFL rules to confirm the positional mooring system’s design meets levels of safety recognised as acceptable to the industry. In this paper, an introduction to positional mooring systems for FPSOs, considering typical strength aspects is given, followed by a general description of hydrodynamic characteristics of ship shape FPSOs The design aspects of mooring system is then given in section outlining methodology in mooring analysis using either quasi-static or dynamic method.

Ini sesuai Keputusan Menteri (Kepmen) No.51 Tahun 2016 tentang Penetapan Lokasi Pembangunan Sentra Kelautan dan Perikanan Terpadu di Pulau-Pulau Kecil dan Kawasan Perbatasan yang bertujuan untuk mengembangkan jaringan konektivitas hasil tangkapan ikan nelayan untuk dikelola mulai pendaratan, penyimpanan hingga pemasarannya. Selama ini hasil tangkapan ikan dari nelayan hanya dipasarkan pada area terbatas yang dikarenakan sarana transportasi kapal pengangkut ke area pemasaran besar yang belum memadai, misalnya kapasitas kapal angkut yang kecil juga kendala cuaca selama pelayaran sulit diatasi. Desain kapal angkut ikan ikan 60 GT, ruang muat ikan dilengkapi sistem pendingin, dapat difungsikan sebagai kapal kolektor bagi nelayan yang tersebar pada area SKPT untuk mengangkut ikan ke area pemasaran. Pada kajian ini dilakukan analisa terhadap kemampuan olah gerak (seakeeping) hasil desain kapal angkut ikan 60 GT dalam menghadapi gelombang perairan Wilayah Indonesia. Hasil kajian ini sangat diperlukan pihak operator atau kapten kapal dalam mengenal kemampuan olah gerak kapal yang dioperasikan dalam menghadapi gelombang selama berlayar dan dapat selamat dan tepat waktu sampai tujuan yang direncanakan.","PeriodicalId":263381,"journal":{"name":"Wave: Jurnal Ilmiah Teknologi Maritim","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128701837","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
