Hydrodynamic Measurement Tools Used in Marine

It is an indispensable tool of maritime, trade and travel. However, a good knowledge of the hydrodynamic properties of ships is essential for a correct and safe navigation. Each ship has different behavior on and under water. For this reason, many hydrodynamic measurement tools are used in shipping. These instruments are designed to measure the resistance, speed, efficiency and other hydrodynamic characteristics of ships. Data obtained using hydrodynamic measurement tools plays a critical role in optimizing ship performance.

What is a Hydrodynamic Measurement Tool?

Hydrodynamic measurement instruments are underwater devices used to measure the hydrodynamic properties of ships in maritime. These instruments are designed to measure how ships behave on and under water. The resistance, speed, underwater interaction, efficiency and other hydrodynamic properties of ships can be measured by these instruments.

Types of Hydrodynamic Measuring Instruments

The first type of hydrodynamic measurement tool is PIV (Particle Image Velocimetry) Cameras. These cameras are used to study how ships behave on and under water. This camera system uses the particle imaging sensor to measure the movement of water. The second type of hydrodynamic measurement tool is CFD (Computational Fluid Dynamics) Software. Thanks to CFD software, it is possible to mathematically model and analyze underwater features of ships. These software are used to optimize the designs and performance of ships. The third type of hydrodynamic measurement tool is the Satellite Strain Winding System. This system is used to measure the technical information of ships. At least 8 GPS antennas are placed on the surface of the ship in order to measure the effects of the Earth's gravitational field and the deformations of the ship.

1. PIV (Particle Image Velocimetry) Cameras:

PIV cameras are used to study how ships move above and below the water. This camera system uses the particle imaging sensor to measure the movement of water. The use of cameras is indispensable for determining the underwater interaction (vortices, streamlines) and resistance of ships. The working principle of PIV cameras is based on a camera system that tracks the particles in the water during the movement of the water. By obtaining these traces, it is possible to determine the speed of the ship on the water, its displacement pattern and its hydrodynamic effects.

PIV cameras are designed to optimize the performance of ships by visually inspecting the movements and flows of water. These cameras analyze the impact of changes in ship design and performance, helping ships move in faster, safer and less fuel-efficient ways. Generally used by the maritime industry in research and development, PIV cameras are also used to increase the energy efficiency of ships and reduce their environmental impact.

2. CFD (Computational Fluid Dynamics) Software:

CFD (Computational Fluid Dynamics) software is used to mathematically model and analyze underwater features of ships. These software play an important role in optimizing ship designs and performance. CFD eliminates the misleading factors that can be encountered in the data to be obtained by performing real-time experiments by mathematically calculating the resistance, surface friction, underwater interactions and other hydrodynamic properties of the ships. In this way, it is ensured that ships can navigate more efficiently and safely.

A CFD software provides comprehensive information about the ship's design and likewise makes realistic predictions about the ship's performance. Thus, especially during the design of new ships, by using CFD software, each ship design can be improved again and again, so that it can sail more efficiently, faster, safer, more comfortably and more economically.

  - CFD software is used by ship design firms.

  - CFD software are programs that usually run on computers and are often used by engineers.

  - The purpose of these software is to optimize the design and performance of the ship and to minimize the ship's optimum navigation conditions and travel costs.

3. Satellite Deformation Winding System:

One of the hydrodynamic measurement tools used in maritime is the satellite deformation winding system. This system is specially designed to measure the technical information of ships. At least 8 GPS antennas are placed on the surface of the ship in order to measure the deformations of the ships and the effects caused by the earth's gravitational field.

This system is used to increase the performance and safety of the ship by measuring the deformations and expansions that occur in the structure of the ships. It also provides information about the ship's placement and posture. Satellite deformation winding system increases the cruising life of the ships, reduces costs and provides a more efficient navigation.

This measuring instrument is designed to increase the ship's resilience against hardships. By detecting the deformations and cracks in the structure of the ships, it is ensured that these problems are intervened in a timely manner. In this way, it is possible for ships to navigate smoothly for a longer period of time.

Satellite deformation winding system is one of the most effective tools used to measure the hydrodynamic properties of ships. The use of this system has become mandatory for ships to navigate in a safer and more efficient manner.

Conclusion

Accurate examination of hydrodynamic properties in maritime is extremely important to increase the performance of ships and to provide a safer navigation. While each measurement tool serves different purposes, an accurate data extraction process and analysis is critical for the vessel to gain higher performance.

Thanks to these measurement tools, a more efficient travel can be achieved by optimizing the designs and performance of the ships. In addition, possible problems that may occur in the navigation of the ships can be determined in advance and precautions can be taken.

Having accurate knowledge of hydrodynamic measurement tools is an important issue for naval engineers and sailors. In this way, it is possible to travel more safely and comfortably in the seas.
