• General Cargo Terminals: These are general cargo terminals equipped with machinery appropriate to deal with general cargo, a catchall category that includes goods that cannot be defined as either container or bulk cargo. Examples include machinery and vehicles among many others.

Channel and Direct Shipping

• The channels of this port are well-maintained in order to let the traffic flow smoothly. There is a line of direct shipping from this port to major regional ports and other major international ports. Such direct links give a competitive edge thereby making it a vital facility in the goods flow smoothly.

2. Importance of Measuring Ocean Currents at Belgrano Port

Impact on Ship Navigation

Therefore, it becomes relevant to measure currents in Belgrano Port for navigation. Currents may alter both the speed and course of vessels. If proper current information is available, a captain operating in the busy port environment can make more adequate adjustments to speed and course. It helps avoid collision and permits efficient procedures for docking and undocking.

It can affect the effectiveness of the flow of ocean currents on cargo-handling operations. Strong or unstable currents may provide difficulties in handling cranes and other equipment used in handling operations. By measuring currents, a port can effectively schedule cargo-handling operations by considering current conditions in order to minimize waiting times for ships and maximize the efficiency of overall work.

Role in Environmental Monitoring

Ocean current measurements are very important for environmental monitoring in the port area. In the event of an oil spill or other form of contaminant, the data can be used to indicate the spread direction and speed of contaminants. It will really enable the Port of Belgrano to make timely prevention and remedial measures toward the marine environment. Generally speaking, an ADCP current meter is much more advanced and convenient than traditional methods to measure ocean currents. So it is really beneficial for the operation of Belgrano Port.

3. How ADCPs Work - Using the Doppler Principle

Measurement Principle

Acoustic Doppler Current Profiler(ADCP) operate on the basis of the Doppler principle. When an acoustic signal is transmitted into the water by the ADCP current profiler, the signal is scattered by the particles and other substances in the water. Due to the water particles being transported with the ocean current, the scattered signal that is received back by the ADCP flow meter would have a different frequency than the frequency at transmission due to the Doppler effect. Based on this frequency shift, the velocity of the water particles and thus the velocity of the ocean current can be found.

ADCP in Port Ocean Current Measurement: Shipborne ADCP

Shipborne ADCPs are installed on ships. During the movement of the ship in the Belgrano Port area, the ADCP meter continuously sends and receives acoustic signals. Thus, it could estimate current depths at an interesting place along the track of the ship. The data measured will contribute to the current condition analyses of the area in which the ship is sailing in a valuable manner for navigation and operations.

Fixed ADCPs can be installed at pre-determined points in the Belgrano Port area, such as on piers and buoys. These are stationary ADCP profiler that would maintain uninterrupted, periodic surveillance of the currents in their vicinity. In this, the long-term steadiness in data can be obtained concerning the currents, which are useful in describing the general pattern and variation of currents around the port area for a long period.

4. Requirements for High - Quality Measurement of Belgrano Port Currents

Equipment Requirements

• Material Reliability: The materials used for the equipment must be highly reliable to withstand the aggressiveness of the marine environment due to corrosion caused by seawater, humidity, and possible impacts by floating objects.
• Small size, light weight, and low power consumption allow for an ADCP of small size and light weight, which is quite easy to install and operate, especially for shipborne ADCPs. Low power consumption allows the equipment to work for a quite long time and without frequent replacement of batteries or large and powerful supply. Such features are very important for both fixed and shipborne ADCPs.
• Relatively Low Cost for Mass Measurement: The actual cost of the equipment to carry out large-scale current measurement in the port should be low enough to execute the task. This allows deploying multiple ADCPs at different locations in the port to get more complete current data.

The Advantage of Using Titanium Alloy for ADCP Casing

• Titanium alloy is a very good material for making ADCP casing. Several major advantages of this are. Firstly, it has very excellent corrosion resistance that can effectively bear the corrosive impact seawater may bring about, thus ensuring long-term stability and reliability in the equipment; secondly, it has a high strength-to-weight ratio, which means that enough strength could be ensured with relatively low weight, meeting the requirements of small size and light weight. Good thermal stability of the titanium alloy; in case of different temperature environments of the Belgrano Port area, it will ensure a good effect on the normal operation of equipment.

5. How to Choose the Right Equipment for Current Measurement

According to the Use Purpose

• Shipborne ADCP: If the measurement is mainly performed on ships, then the shipborne ADCP can also be considered appropriate. It can move along with the ship and measure currents across different areas of the port while the ship navigates.
• Sitting - Bottom ADCP: For long-term fixed-point monitoring at a specific location in Belgrano Port, it's a good choice since currents can be continuously monitored within its proximity. It is normally placed on the seabed with an installation at such locations. Buoy - Type ADCP: This is fitting 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 suit different water depths. For example, 600 kHz ADCP can work within 70 m of water depth. It provides higher resolution in the current measurement in a relatively shallow water area. For 300 kHz ADCP, it fits water up to 110 m in depth, and for 75 kHz ADCP, it is fit for much deeper water-say, 1000 m. This allows measurements of currents with water depth conditions as actually occurring at any depth in the Belgrano Port.

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.
