“…This simple model proved to be adequate for short term prediction of the trajectory of the ship Maimun et al (2011);Milanov et al (2011); Skjetne et al (2004). Moreover, it allowed to reduce the number of variables and equations involved, reducing simulation time without losing relevant information.…”

This paper presents a short-term time-domain algorithm for ship motion simulation. Plane motion is considered, thus a three degrees of freedom model can be used. The main inputs of the model are: propellers speed, rudder angles and initial conditions (in terms of initial position/orientation and linear/rotational velocity). The outputs are final ship position and orientation after a given simulation time. The huge amount of data available in the Voyage Data Recorder (VDR) and the results of sea trials performed before the ship delivery can be used to estimate the needed parameters, implementing a simple but reliable linear regression scheme. As a case study, the proposed model was applied to Costa Concordia manoeuvring simulation in order to asses its reliability in terms of trajectory prediction. Finally, as an example of application, the simulator was implemented in a real time manoeuvring predictor, which is capable of foreseeing the ship position up to 40 s ahead in time, supporting the Commander in emergency operations.

“…Hasil penelitian terdahulu menyebutkan sejumlah pengaruh yang berpotensi terhadap pengurangan tingkat kemampuan maneuvering kapal ferry ro-ro antara lain adalah kapal dengan sarat (T) yang relatif rendah [3], faktor lingkungan pelayaran seperti halnya tingkat kedalaman perairan [4], kecepatan angin dan tinggi gelombang [5 dan 6] serta bangunan atas yang relatif besar [7]. Penomena diatas secara signifikan dapat mengubah kecepatan dan arah gerak kapal sebagai akibat reaksi gaya dan momen yang ditimbulkan saat kapal bermanuver, kondisi ini dapat lebih diperburuk dengan meningkatnya kemiringan kapal, namun dengan kecepatan operasi kapal yang rendah serta perbandingan B/T yang relatif besar hal ini dapat mengurangi kemiringan kapal ferry ro-ro (atau ≤10 deg) sebagaimana penelitian Muhammad et al [8].…”

Kapal ferry ro-ro sesuai fungsinya sebagai kapal penyeberangan penumpang dan kendaraan antar pulau memiliki karakteristik yang berbeda dibanding kapal niaga pada umumnya, khususnya pengunaan sistem kemudi ganda dengan rasio jarak antar daun kemudi yang relatif besar, hal ini sangat berdampak terhadap kemampuan olah gerak kapal. Penelitian ini bertujuan untuk menganalisis kemampuan maneuvering kapal ferry melalui pengaturan sudut kemiringan dan jarak antar daun kemudi. Program MATLAB-Simulink digunakan dalam simulasi turning circle dan zigzag maneuvering. Program simulasi telah dikembangkan dengan konsep time domain simulation berdasarkan persamaan model matematika pergerakan kapal pada 3-DOF (Degres of Freedom) yang meliputi persamaan komponen lambung, propeler dan daun kemudi beserta koefisien hidrodinamaka didalamnya. Hasil penelitian menujukan bahwa seiring dengan bertambahnya sudut kemiringan daun kemudi dapat meningkatkan kemampuan turning circle kapal, namun sebaliknya pada gerak zigzag maneuvering. Selanjutnya dengan bertambahnya jarak antar daun kemudi dapat meningkatkan kemampuan baik turning circle dan zigzag maneuvering, namun dengan momen daun kemudi yang relatif besar maka hal ini dapat membahayakan kapal.

“…Before continuing the analysis, it is important to remember that the ship’s manoeuvrability is significantly affected, amongst other things, by its interaction with the bottom of the waterway; the resulting turning circles will have different characteristics that should then be considered [29].…”

Aids to Navigation (AtoN) are auxiliary devices intended to support maritime navigation. They include both traditional signals (e.g., buoys and lights) and electronic aids, as for example those transmitted to ships through automatic tracking systems. In both cases, international organizations together with local authorities define technical specifications and standards on their use. Work still being finalized in the Venetian Lagoon made it necessary an assessment of the existing signaling system to guarantee the maximum level of safety in the waterways. Considering the severe atmospheric conditions to which the Lagoon is frequently subjected and the bathymetry restrictions affecting the navigation, an alternative aid system has been formalized for the first time in Italy. It is based on electronic and identification devices employed to virtualize the AtoN that will not be located at sea but only remotely identified by their coded messages, thus guaranteeing the continuity of port operations in any visibility conditions. This paper presents the procedures followed to reach a solution in line with the safety and efficiency standards given for the AtoN systems, considering position and luminous characteristics of physical signals in the first case, theoretical and statistical studies on Virtual AIS AtoN placement in the second case.
