2. Importance of Measuring Ocean Currents in Quequén Port

Impact on Ship Navigation

Current measurement at Quequén Port is indispensable for properly navigating ships through it. Currents can have a great influence on the speed and course of ships. In a fairly trafficked port, proper information about currents has an effect on ship captains, enabling them to change their speed and course much more effectively. Such a thing will help prevent collisions and easily allow maneuvers in docking and undocking. The flow of ocean currents can affect the efficiency of cargo-handling operations. In rough or strong currents, ships operate less accurately with cranes and other handling equipment. Based on the measurement, the port can undertake better scheduling of cargo-handling operations according to current conditions, which reduces waiting times for ships and enhances the efficiency of work in general.

Role in Environmental Monitoring

One of the most important environmental monitoring activities in a port area is ocean current measurement. In the case of an oil spill or any other contaminants, the current data will ascertain the direction and rate at which pollutants are spreading. It affords the port an opportunity to take timely precautionary measures or other remedial actions to protect the marine environment. In respect of this, ADCP profiler is more advanced and convenient in measuring ocean currents compared to other conventional methods.

3. How ADCPs Using the Doppler Principle Work

Measurement Principle

Acoustic Doppler Current Profiler(ADCP) operate on the principle of the Doppler. When an acoustic signal is transmitted into the water by the ADCP meter, the signal is scattered by particles and other substances in the water. Since the water particles move with the ocean current, the scattered signal frequency received back by the ADCP flow meter will be different from the transmitted one due to the Doppler effect. By measuring this shift of frequency, the velocity of the water particles and hence the ocean current is derivable.

ADCP in Port Ocean Current Measurement: Shipborne ADCP

It is installed on ships. While the ship sails in the area of Quequén Port, the ADCP current profiler continuously transmits and receives acoustic signals. The ocean currents can be measured at all depths along the path where the ship has navigated. Data acquired in this way allows the analysis of the current state in the area that the ship is sailing, giving very important information for navigation and other operations of the ship. The fixed ADCPs are normally installed at chosen places in the Quequén Port, such as on piers or buoys. These ADCP current meter do not move from their position and continuously observe the currents of the ocean surrounding them. These can provide long-term steady current data that can be used to understand the general pattern and its variation in current at the port area over some time.

4. High - Quality Measurement Requirements of Currents of Quequén Port

Equipment Requirements

• Material Reliability: The reliability of the materials used in the equipment should be very high because they will be exposed to very adverse conditions such as the aggressive action by the seawater, highly humid air, and impacts that may occur because of floating objects.
• Small Size, Light Weight, and Low Power Consumption: A small-sized and lightweight ADCP is preferable for installation and usage convenience, especially for shipborne ADCPs. Low power consumption allows the equipment to operate for a long time without frequent battery replacement or high-power supply requirements, which is important for both fixed and shipborne acoustic doppler velocity meters.
• Low Cost for Mass Measurement: The cost of the equipment in implementing large-scale measurement of current in a port should not be too high, so that it would be easy to install at many places within the port using multiple acoustic doppler flow meter. This can enable the acquisition of more current data.

Advantage of the Use of Titanium Alloy for Housing of ADCP

One of the best materials for an ADCP casing is the Titanium alloy. It has a couple of advantages. It has excellent corrosion resistance and can effectively withstand the corrosive effects of seawater in order to ensure the long-term stability and reliability of the equipment. This material also features a high strength-to-weight ratio, which means that it would be able to provide adequate strength while keeping the weight relatively low, meeting the small size and lightweight requirements. Third, the heat resistance of the titanium alloy is very outstanding, which is useful for normal operation of the device in the Quequén Port area with different temperature environments.

5. Selection of Equipment for Current Measurement

Based on Use Purpose

It would be advisable to make use of the shipborne ADCP where measurement is mainly carried out on ships. It can move along with the ship and measure the currents in the different areas of the port as it navigates.

Sitting-bottom ADCP: this one would be appropriate for monitoring the current from a long-term fixed-point in a particular place within the Quequén Port. Normally, it is installed on the seabed, where it continuously can monitor the currents in its vicinity.

Buoy - Type ADCP: Buoy - type ADCP is suitable for applications where real - time monitoring of currents in a certain area of the port is required. The buoy can float on the water surface and the ADCP on it can measure the currents around it.

Selection Based on Different Frequencies

Different frequencies of ADCPs are suitable for different water depths. For example, the 600 kHz ADCP is fit for water within 70 m; it can provide more details of current data in a relatively shallow water area. 300 kHz ADCP is fit for waters up to 110 m in depth, and 75 kHz ADCP will be fit for much deeper water-up to 1000 m. This will enable the realization of current measurements at different depths in Quequén Port for real situations of water depth.

There are several well - known ADCP brands such as Teledyne RDI, Nortek, and Sontek. However, for those looking for cost - effective options, the Chinese brand China Sonar PandaADCP is highly recommended. It is made of all - titanium alloy material and has an incredible cost - performance ratio. You can visit its website https://china-sonar.com/ for more information.
