“…Resistance is a characteristic parameter of the hydrodynamics of the hull [13]. The level of ship resistance is strongly influenced by the speed of the ship (Vs), displacement (∆), and the shape of the hull form [14]. The value of the ship's resistance is directly proportional to the speed of the ship.…”

This study aims to analyse the effect of variations in the addition of bilge keel on the value of resistance, ship stability, and seakeeping performances. The research method is carried out by designing and analysing the hull design of the fast patrol boat type with variations in the addition of a bilge keel. Variations made on the bilge keel include length and width. The length variations are considered by applying 4 m, 5 m, and 6 m, while the variations in width include 0.3 m, 0.4 m, and 0.5 m. This study indicates that the nine variations of the bilge keels model with a combination of length and width do not show a significant difference in the resistance value on each ship. Then, for the stability criteria, the bilge keel model IX, with a length of 6 m and a width of 0.5 m, has the best stability value compared to other variations. Meanwhile, the addition of bilge keel in the seakeeping simulation did not show a significant difference. The parameters of this analysis consider the primary needs of fast patrol boats to support the development of shipping technology.

“…This intensive trial was directed to optimize the combination of the functions of the three sensors. More research can be directed to propulsion/turbine and hull material concepts, which these work [12][13][14][15][16][17] can be viable references in future works.…”

Mandakini Neo is an autonomous vehicle that was designed and built by the students of the Universitas Sebelas Maret, which was included in the Bengawan Unmanned Vehicle (UV) Roboboat Team to compete in the annual international Roboboat competition of 2021. This competition requires participants to complete several missions; one of the main missions is to move through two gates made from four poles using full automatic navigation, in order to continue on with the other missions. To complete the course, we used Pixhawk and GPS to allow the ship to run automatically, while minimizing the ship’s movement tolerance. The use of Mission Planner software for monitoring, and also for color and shape image processing to help with the reading of objects, along with a sensor fitted on the ship, allowed the mission to be completed. Mandakini Neo was made with the capacity, speed, and comfort of the ship in mind, as well as the ship’s hydrodynamic performance, stability, volume, structural integrity, and construction cost. Following its development we conducted tests of stability, maneuverability, and seakeeping in order to achieve the smallest possible resistance rate; for this purpose, we used the Savitsky method. The manufacture of the ship also required the choosing of the material, the use of the sensor, and also selection of an appropriate system. Finally, the design that we developed was a ship with a catamaran hull type, for which the dimensions had already been calculated, and the proper materials decided, and simple electrical components were able to be obtained for the sensor and the system.

“…When the equilibrium state is stable, the center of buoyancy and gravity are in one direction, and the longitudinal and transverse lines are aligned with the trim angle. Flooding on the ship will also affect the trim angle, dynamic stability, roll period, and pitch period, and these factors contribute significantly to the ship's sinking [9][10][11][12][13].…”

The prevalence of maritime accidents that occur due to ship leakage causes a significant risk to the safety of passengers and crew. Therefore, it is important to estimate stability during critical conditions, including characterizing the hull performance in sailing conditions. This research analyzes the effect of compartments and bulkheads on the ship’s stability when a leak occurs. The research method was carried out using the numerical approach to obtain resistance, stability, and large-angle stability results. The study also uses floodable length simulations to predict ship leakage and the distance between compartments. The variations were composed, including the location of the compartments and the distance between the partitions. Based on the obtained results, it can be seen that the addition of the compartment will affect the intensity of the ship to sink completely. Furthermore, the effect of leakage in each compartment will contribute to the stability state of the ship.
