    Opis:
    Since January 2021, Havila Kystruten has been one of two companies sailing the coastal route between Bergen and Kirkenes. This paper contains information on the new shipping company Havila Kystruten and their 2019 bid for a 10-year operational license to sail the coastal route. The government's tender documents for the new license specified that the vessels operating the route had to be low-emission vessels. This requirement was in line with the government's white paper on the reduction of emissions for commercial and fishing vessels sailing in Norwegian waters. Thus, companies bidding for the new license had to offer new ships with low emission characteristics or rebuild existing vessels to obtain the low emission requirements. Based on the offers, the government decided to split the operational license between two companies. One part was given to the company previously operating the route (Hurtigruten) and the other to the new company Havila Kystruten. While Hurtigruten would rebuild the engine systems on some of their existing vessels, Havila Kystruten would operate the route using new vessels with low emission signature. The design requirements for these vessels were given by Havila Kystruten to the ship designer, Havyard Design and Solutions (now HAVDesign). Some of the requirements are listed in section 4 below. The latter part of this paper investigates the manoeuvring performance of the new Havila Kystruten vessels, containing a summary of a Research Council of Norway funded innovation project on harsh weather ship handling during port operations. The Port of Trondheim was selected as a case study.

    Opis:
    The German-funded FernSAMS project aimed at the development of an unmanned, remote-controlled tug operation with AR/VR technology. After an extensive simulation test with ship-handling simulators, the developed FernSAMS AR/VR system has now been in-situ tested with a scale model of the tug. The model test results showed very robust stability in remote operations with improved situational awareness with the VR/AR system and sensors. After a short introduction of the FernSAMS concept as well as some first insights into FernSAMS Human-Machine-Interface tests within the simulator, this paper introduces the technical setup of the scale-model tests being conducted with the FernSAMS concept to test the operational and technical feasibility of AR/VR-based remote control. This includes an overview of the systems and sensors integration and an analysis of the effectiveness of AR/VR system combined with 360-degree video streaming.

    Opis:
    The research addresses the problem of an ultra-large container ship mathematical model adjustment based on sea trials. In order to verify the model’s adequacy, simulated data had to be compared to the trial report data, which was obtained in ballast condition with significant trim. In such circumstances, model coefficients cannot be calculated by known methods and have to be corrected as per trial data. It is proposed to determine translational motion coefficients first. To get optimal results, it was also proposed to divide the objective function into kinematic and dynamic components, with each component being assigned a weighting factor. A separate objective function component was assigned to the zig-zag maneuver, which includes the first and second overshoot angles.

    Opis:
    Ship maneuvering models are the keys to the research of ship maneuverability, design of ship motion control system and development of ship handling simulators. For various frames of ship maneuvering models, determining the parameters of the models is always a tedious task. System identification theory can be used to establish system mathematical models by the system’s input data and output data. In this paper, based on the analysis of ship hydrodynamics, a nonlinear model frame of ship maneuvering is established. System identification theory is employed to estimate the parameters of the model. An algorithm based on the extended Kalman filter theory is proposed to calculate the parameters. In order to gain the system’s input and output data, which is necessary for the parameters identification experiment, turning circle tests and Zig-zag tests are performed on shiphandling simulator and the initial data is collected. Based on the Fixed Interval Kalman Smoothing algorithm, a pre-processing algorithm is proposed to process the raw data of the tests. With this algorithm, the errors introduced during the measurement process are eliminated. Parameters identification experiments are designed to estimate the model parameters, and the ship maneuvering model parameters estimation algorithm is extended to modify the parameters being estimated. Then the model parameters and the ship maneuvering model are determined. Simulation validation was carried out to simulate the ship maneuverability. Comparisons have been made to the simulated data and measured data. The results show that the ship maneuvering model determined by our approach can seasonably reflect the actual motion of ship, and the parameter estimation procedure and algorithms are effective.

    Opis:
    This concept paper described the process of bridging the gaps in one of the methods for determining wheel over point (WOP). WOP is a marking made on charted courses to indicate a point at which a ship should change course. Identifying WOP is vital to avoid the vessel overshooting the planned track. One method for determining WOP is the advanced transfer technique. However, two issues were identified while reviewing this technique. Therefore, an improved mathematical model could be developed to overcome these problems. A manoeuvring analysis using a ship simulator will be performed to test the developed mathematical model's efficacy. The data obtained from the simulation study can be validated further by its adherence to the cross track limit, reduction in percentage change, and using IBM SPSS for the Mann-Whitney U test. The developed mathematical model is expectantly capable of producing a better track-keeping function and suitable for use onboard a cargo ship. The mathematical model also could be implemented as an algorithm in the Electronic Chart Display and Information System to help navigators make more efficient course changes.
