Analisis Pengaruh Variasi Jarak Horisontal Antara FSRU Dan LNGC Saat Side By Side Offloading Terhadap Perilaku Gerak Kapal Dan Gaya Tarik Coupling Line

Teknologi transfer LNG antara dua bangunan apung merupakan komponen yang cukup penting pada operasi FSRU. Sistem transfer LNG dengan menggunakan konfigurasi side by side menciptakan jarak horisontal antara lambung FSRU dan LNGC. Pada penelitian ini akan dikaji pengaruh variasi jarak horisontal terhadap perilaku gerak bangunan multibody dan terhadap gaya tarik tali tambatnya yang menghubungkan kedua lambung kapal. Variasi jarak horisontal yang dikaji mengacu pada kriteria operasi loading arm sebagai alat transfer LNG berdasarkan OCIMF, yaitu 2.5, 4, 6 dan 8.5 meter. Penelitian ini menyajikan metodologi berbasis frekuensi untuk menghitung perilaku gerak bangunan apung dan metodologi berbasis waktu untuk menghitung gaya tarik tali tambatnya. Berdasarkan analisis tersebut variasi jarak horisontal kurang memberikan pengaruh yang signifikan terhadap perilaku gerak bangunan apung yaitu memberikan beda sekitar 1% pada tiap penambahan jarak horisontalnya. Sedangkan pada gaya tarik tali tambat memberikan pengaruh cukup signifikan terhadap intensitas gayanya sesuai dengan arah beban gelombang yang mengenai struktur apung. Arah beban gelombang perempat haluan maupun buritan meyebabkan naiknya nilai gaya tarik tali tambat terhadap pertambahan jarak horisontal yaitu sekitar 80 s.d. 90% pada gaya tarik signifikan spring linenya (tali 4)pada kondisi steady state, sebagai akibat dari pertambahan luasan bidang kapal yang terkena tekanan gelombang melalui celah yang terbentuk antara FSRU dan LNGC. Sedangkan arah beban gelombang sisi menyebabkan turunnya nilai gaya tarik tali tambat terhadap pertambahan jarak horisontal yang terbentuk yaitu sekitar 25 s.d. 75%, pada gaya tarik signifikan spring linenya (tali 7) pada kondisi steady state sebagai akibat dari bidang luasan LNGC terkena tekanan gelombang yang terdifraksi badan FSRU. ================================================================================================================================ The technology of LNG transfer between two floating vessels is a crucial component of FSRU operation. Side by side configuration of LNG transfer creates a gap (horizontal distance) between FSRU and LNGC body. This research has been carried out by investigating the influence of various horizontal distance between FSRU and LNGC towards it’s motion and coupling line tension. The horizontal distance based on operating criteria of loading arm issued by OCIMF : 2.5, 4, 6 and 8.5 meters. This paper will present a metodology of frequency domain to analyze multibody motion and time domain to analyze coupling line tension. Based on this research the variety of horizontal distance has no significant effect towards multibody motion by interval 1%. But it has significant effect towards the coupling line tension due to the heading of wave pressure working on it’s body. The obligue wave invents increasing the horizontal distance of length to the bigger load intensity of coupling line significant tension by interval 83 to 90% (line 4 of spring line) at steady state due to the increasing LNGC area impacted by wave pressure. And the beam wave influences decreasing of the horizontal distance towards the bigger load intensity of coupling line significant tension by interval 25 to 75% (line 7 of spring line) at steady state due to the wave diffraction impacted to LNGC area

Analisis Pengaruh Gaya Gelombang Non-Linier Orde-2 Terhadap Struktur Apung Tertambat Dengan Sistem External Turret Mooring

Struktur apung tertambat pada gelombang acak akan menerima beban gelombang orde-1 dan orde-2. Penelitian mengenai gaya gelombang orde-1 telah cukup banyak dilakukan selama beberapa dekade, mengingat pentingnya gaya orde-1 terhadap struktur apung. Penelitian ini difokuskan untuk mengkaji pengaruh gaya gelombang orde-2 terhadap sistem struktur tertambat external turret mooring dengan konfigurasi 6 tali catenary. Tipe gaya gelombang yang bekerja divariasikan untuk menyelidiki pengaruhnya terhadap respon struktur tertambat dan gaya tarik (tension) tali tambatnya. Simulasi dilakukan dengan memodelkan kapal tanker ukuran Aframax 120.000 DWT dalam 3 kondisi pembebanan : sistem tertambat yang dikenai gaya gelombang orde-1, gaya gelombang orde-2 dan kombinasi keduanya. Penelitian ini menggunakan pendekatan domain frekuensi untuk menghitung perilaku hidrodinamis struktur terapung bebas. Kemudian hasil tersebut digunakan untuk melakukan simulasi dalam domain waktu secara simultan untuk mendapatkan perilaku gerak struktur tertambat dan tension tali tambatnya. Respon struktur dan tension tali tambat dalam domain waktu kemudian ditinjau kembali dalam domain frekuensi menggunakan metode fast fourier transform (FFT) untuk menyelidiki karakteristiknya akibat tipe gaya gelombang yang bekerja. Simulasi yang telah dilakukan menunjukkan bahwa meskipun intensitas gaya orde- 2 terbilang rendah, namun dapat menghasilkan respon surge dan tension tali tambat yang cukup tinggi akibat adanya fenomena gerakan seret (drifting). Amplitudo respon surge akibat gaya orde-1 dengan Hs mencapai 10m adalah sekitar 2m, sedangkan orde-2 menghasilkan sekitar 23m, sehingga rasio perbandingannya sekitar 1 : 11. Amplitudo tension akibat orde-1 mencapai 7,5 ton dan akibat orde-2 sekitar 117,5 ton sehingga rasio perbandingannya mencapai 1 : 15. Variasi kedalaman perairan juga diselidiki untuk mengetahui pengaruhnya pada respon tertambat akibat gaya gelombang orde-2, yaitu pada kedalaman 100, 300 dan 500m. Hasil yang didapatkan dari simulasi tersebut mengindikasikan bahwa setiap penambahan kedalaman perairan sebesar 200 m dapat meningkatkan respon surge akibat gaya orde-1 sebesar 5 – 9% atau sebesar 2 -5 meter dan akibat orde-2 sebesar 9 – 19% atau sekitar 7 – 12 meter. Penambahan kedalaman perairan juga meningkatkan tension tali tambat akibat orde-1 sebesar 60 - 65% atau sekitar 28 – 135 ton dan akibat orde-2 mencapai sekitar 75% atau sekitar 152 ton. =============================================================================================== Moored floating structures in random waves are subjected to large first order and small low frequency second order wave forces. Due to the importance of the first order wave force and motions they have been subject to investigation for several decades. This study focuses to investigate the second order wave force effect towards floating structure responses and mooring line tensions. A moored structure is configured as an external turret system which is anchored by 6 catenary mooring lines. Variation in the type of wave forces acts on Tanker model Aframax 120.000 DWT is investigated in order to predict the effect of second order wave force. The simulations are performed in 3 loadcases : moored floating structure subjected to first, second order wave forces and combination of both respectively. In this study, modelling on the basis of the frequency-domain is adopted to compute the hydrodymanic properties of freely floating structure and followed by simulation on the basis of time-domain coupled dynamic analysis to observe the responses of moored floating structure and tension of mooring lines. All responses and its tension re-observed in frequency domain using the Fast Fourier Transform method in order to investigate its characters. The corresponding analysis reveals that the low frequency second order wave force, even though relatively small in magnitude, could excite large both amplitude of surge motion and tension of mooring lines. It may give rise to the amplitude of surge motion from 2m (first order) to 23m (second order) so the ratio of motion is 1 : 11. And for mooring line tension, it rise from 7,5ton (first order) to 117,5ton (second order, so the ratio of tension is 1 : 15.Variation in the water depth is also investigated in order to calculate its effect towards structure responses and mooring line tensions, namely 100m, 300m and 500m. The analysis reveals that increasing water depth per 200m, it may give rise the surge response due to first order wave force in 5 – 9% (2 – 5 meter) and 9 – 19% (7 – 12 meter) due to second order wave force. Also it may give rise the mooring line tension due to first order wave force in 60-65% (28 – 135 ton) and around 75% (152 ton) due to second order wave force

Analysis of Compliance Level of Fishing Activities In The Natuna Sea

Illegal fishing in Indonesian territorial waters, especially by foreign fishermen, has harmed the Indonesian state financially, because it has contributed greatly in reducing productivity and catches very significantly. It has has also threatened the sustainability of the utilization of Indonesia’s marine fishery resources. Economic losses due to IUUF are not only in the form of state income which reaches the range of Rp. 30 trillion per year, but also the loss of opportunities to utilize fish resources of around 1 million tons of fish each year that can be caught (harvested) by Indonesian fishermen, and what happens is in fact stolen by foreign fishermen. entering Indonesian waters. Foreign fishermen who often enter Indonesian waters, among others, come from Thailand, Vietnam, the Philippines, and Malaysia. To prevent and overcome IUUF activities, one of the steps taken by the Ministry of Maritime Affairs and Fisheries (KKP) of the Republic of Indonesia through the Directorate General of Supervision of Marine and Fishery Resources (DITJEN PSDKP) is to supervise fisheries such as fishing activities in the fisheries management area of ​​the Republic of Indonesia. Supervisory implementation is carried out by the Technical Implementation Unit (UPT) PSDKP. UPT Directorate General of PSDKP in handling its duties is supported by the Marine and Fishery Resources Supervision Unit (PSDKP Satker) and Marine and Fishery Resources Monitoring Post (PSDKP Post) spread throughout Indonesia. In carrying out its duties, the Fisheries Supervisory Vessel may stop, inspect, carry, and detain ships suspected of violating the law to the nearest port for further processing. In addition, based on Law No. 31 of 2004 concerning Fisheries, as amended by Law No. 45 of 2009, in certain cases Fishery Supervisory Vessels, in this case, fishery supervisors or Fisheries Civil Servants Investigators, can also take special actions in the form of drowning. The high level of fishing activity in the Indonesian State Fisheries Management Area 711 must be accompanied by adequate monitoring activities to ensure compliance by business actors, both industrial scale and small fishermen, so that the sustainability of fisheries resources can be maintained
