Perancangan Sistem Kontrol Sandar Kapal Otomatis Berbasis Logika Fuzzy Di Pelabuhan Tanjung Perak Surabaya

Tugas akhir ini berkaitan dengan perancangan simulasi sistem kontrol sandar otomatis dengan jenis kapal AHTS (Anchor Handling Tug Supply). Sistem auto pilot yang digunakan dalam simulasi ini menggunakan Kontrol Logika Fuzzy (KLF) Sugeno-Takagi. Kontrol Logika Fuzzy digunakan untuk kontrol kemudi (rudder), stern thruster, dan bow thruster selama proses sandar kapal. Simulasi ini menggunakan data dari spesifikasi kapal yang sebenarnya dan menggunakan model pendekatan Nomoto orde II. Agar hasil simulasi mendekati kondisi yang sebenarnya, dilakukan pemodelan arus laut dengan kecepatan arus sesuai dengan kondisi di pelabuhan Tanjung Perak. Hasil penelitian menunjukkan bahwa simulasi sistem kontrol sandar kapal otomatis dapat mengikuti trayektori (set point) yang telah ditentukan dan mempertahankan posisi heading sandar kapal. Dengan error trayektori antara jalur yang ditentukan dengan jalur sebenarnya jika tidak ada gangguan arus laut maka root square error maksimum trayektori sebesar 0.39 m. Dengan adanya gangguan arus laut 2; 2,25 dan 2,5 knot root square error maksimum trayekori sebesar 1,26; 0,64 dan 2,68 m. Sedangkan untuk tahapan sandar kapal arah kapal dengan gagguan arus laut 2; 2,25 dan 2,5 knot menghasilkan error sebesar -0,110; -0,060 dan -0,030. Waktu yang ditempuh untuk sandar kapal tanpa ada gangguan selama 668 detik, dengan adanya gangguan arus 2; 2,25 dan 2,5 knot berturut-turut selama 113, 96, dan 99 detik

Florida Boating Access Facilities Inventory and Economic Study, including a Pilot Study for Lee County: A report to the Florida Fish and Wildlife Conservation Commission

This report describes the work program and results of the Statewide Boating Access Facilities Inventory and Economic Study Including a Pilot Study for Lee County, Florida commissioned by the Florida Fish and Wildlife Conservation Commission (FWC) in 2005. The study was funded in part by a grant to the FWC from the U.S. Fish and Wildlife Service and by Lee County. The scope and objectives of the study are summarized in the introduction, and the subsequent sections report on the various components of the study. For many years, Florida has been among the fastest growing states in the nation, which means that its resources, infrastructure, and facilities are continually under pressure. Maintaining the quality of the state is natural resources and access to its waters depends on making informed management decisions using the best scientific data and analyses available

Berthing Assistant System Using Reference Points

With more goods to be transported oversea, traffic and vessels dimensions increase while berthing areas merely remain constant and thus challenge ship masters and pilots to maneuver in small basins with dense traffic even in bad weather situations. Too fast approaches or steep angles of attack result in damages to fenders, quay walls, or even impact the hull structure. We propose a shore-based, vessel-independent berthing assistant system to support sailors by Reference Points that are aligned to a quays meter markings and identify the precise berthing location by measuring distance and approach speed. For this purpose, we define the concept of a Berthing Support Area (BSA), which specifies an area in which, subject to constraints, safe berthing is provided. Within this area there are Reference Points, perpendicular distance measurements at arbitrary positions, which are implemented with a set of LiDAR sensors that have been integrated into the quay wall. In a test campaign with a vessel equipped with DGPS sensors, we sailed seven different maneuvers and evaluated the precision and the accuracy of the Reference Points for speed and distance measurements

Development of a maritime education and training institute in Ethiopia : considering the priorities

The purpose of this paper is to show the significance of establishing a maritime training institution in Ethiopia, to foster the development of the shipping industry in particular, and of the nation as a whole. The main argument for the establishment of, the maritime training institution is the need to pave the way towards the country\u27s, integration into the maritime world economy, which demands well qualified seafarers and maritime experts to run the different aspects of the maritime industry. To clarify the present situation of the country, brief information on geo-political and socio-economic conditions has been included. Acquaintance is’ olso made to the ancient maritime history, to show the extent of the nation\u27s maritime achievements, and its contributions to the making of maritime history. Furthermore, to provide a clear basis for comparison, and to further highlight the significance of the training center, the activities and operation of the merchant fleet, together with the existing shortages of trained manpower are illustrated. In addition to that, proposals are presented regarding: -organization and administration of the institution\u27 -staff requirements and criteria -construction sites and buildings -requirements of training facilities and equipment -curricula and syllabi for cadet and rating training, and -examination and certification procedures

Next generation mine countermeasures for the very shallow water zone in support of amphibious operations

This report describes system engineering efforts exploring next generation mine countermeasure (MCM) systems to satisfy high priority capability gaps in the Very Shallow Water (VSW) zone in support of amphibious operations. A thorough exploration of the problem space was conducted, including stakeholder analysis, MCM threat analysis, and current and future MCM capability research. Solution-neutral requirements and functions were developed for a bounded next generation system. Several alternative architecture solutions were developed that included a critical evaluation that compared performance and cost. The resulting MCM system effectively removes the man from the minefield through employment of autonomous capability, reduces operator burden with sensor data fusion and processing, and provides a real-time communication for command and control (C2) support to reduce or eliminate post mission analysis.http://archive.org/details/nextgenerationmi109456968N
