ADCP's Application to Ocean Current Measurement in Santo Domingo Port

1. Where is the Santo Domingo Port?

Overview of the Santo Domingo Port

The Puerto Santo Domingo, as it is most commonly known in English, or the Santo Domingo Port, is located on the southern coast of Hispaniola, home of the Dominican Republic. It stands out as the largest and busiest port in the Dominican Republic, serving as an important gateway for trade and tourism in the Caribbean region.

Port Scale and Throughput

The Port of Santo Domingo handles in excess of 1.2 million TEUs annually and is one of the most important containerized cargo hubs in the Caribbean. The port also manages considerable volumes of bulk cargo, such as petroleum, agricultural products, and building materials. Hundreds of thousands of tourists enter through the port's cruise terminals every year, boosting the nation's tourism-driven economy.

Shipping Routes and Operations

It is strategically located along the major shipping routes that link North America, South America, Europe, and the Caribbean. It provides facilities such as handling of containers, bulk cargo operation, cruise ships, among others, managed by Dominican Port Authority - APORDOM. It plays a vital role in the import-export-based economy of the Dominican Republic, especially in regards to goods such as textiles, electrical appliances, and pharmaceuticals.

Port Facilities and Navigation Channels

Santo Domingo Port features a modern infrastructure of deep-water berths capable of handling Panamax and Post-Panamax vessels. The navigational channels were dredged for up to 12 meters of depth, safely allowing big vessels to pass. The key facilities include the Don Diego Container Terminal, specialty bulk cargo areas, and even a cruise ship terminal with all the necessary facilities for tourists.

2. Why Should We Measure the Ocean Currents in Santo Domingo Port?

Importance of Ocean Current Measurement Ocean current data is important in the Santo Domingo Port because of the following reasons:

1. Navigational Safety: Strong Caribbean currents and tidal fluctuations near the entrance of the port can challenge vessel maneuverability. Accurate current data helps pilots navigate safely by minimizing collision risks.
2. Operational Efficiency: Knowledge of tidal currents optimizes docking schedules, reducing fuel consumption and minimizing delays in cargo handling.
3. Protection of the Environment: Present monitoring aids in assessing sediment transport, pollution dispersion such as oil spills, and its effects on the local coral reefs that are so important for biodiversity in the area.
4. Infrastructure Maintenance: Current patterns drive sedimentation rates in navigation channels, informing efficient dredging schedules.

ADCP: The Advanced Solution

Acoustic Doppler Current Profilers have made current measurement a real-time, high-resolution activity across entire water columns. Unlike conventional methods, ADCPs are non-invasive, power-efficient, and suitable for dynamic port conditions like those in Santo Domingo.

3. How Do ADCPs Using the Doppler Principle Work?

The Doppler Principle

ADCPs emit high-frequency acoustic pulses into the water. When these sound waves encounter suspended particles such as plankton or sediment, they scatter back to the device. The frequency shift between outgoing and returning waves, due to the Doppler effect, allows for the precise calculation of current speed and direction at multiple depth layers.

ADCP Deployment Methods in Ports

• Vessel-Mounted ADCPs: These are fitted on vessels or survey boats to make spatial current measurements while in transit. Suitable for mapping currents around shipping lanes, berthing areas, and dredging zones.
• Fixed ADCPs: Seafloor-mounted or pier/buoy-mounted instruments, these measure currents continuously over periods of time. Applied in the study of the tidal cycles, storm surges, and seasonal variations of currents.

4. What is Needed to Achieve Quality Measurement of Currents in the Santo Domingo Port?

ADCP Requirements

1. Durability: The tropical marine environment requires resistance to corrosion. Titanium alloy casings are ideal, with resistance against saltwater, biofouling, and physical wear.
2. Compact and Lightweight Design: To allow for easy deployment in busy port areas without disrupting vessel traffic flow.
3. Low Power Consumption: Critical for fixed ADCPs reliant on battery/solar power to ensure continuous data collection.
4. Cost-Effectiveness: Affordable solutions enable widespread deployment across the diverse operational zones of the port.

Benefits of Titanium Alloy Casing

• Resistance to Corrosion: Resists prolonged immersion in saltwater and humid tropical climates.
• Strength-to-Weight Ratio: High: Ensures strength yet simplifies installation and retrieval processes.
• Non-Magnetic in Nature: At the front end, it eliminates interference with the ADCP sensors for accurate delivery of data.

5. How to Choose the Right Equipment for Current Measurement?

Choosing the Right ADCP

• Vessel-Mounted ADCPs: For hydrodynamic surveys, emergency response, and dredging support, this is the best option. The 600–300 kHz models can be used for shallow to medium depths up to 110 m.
• Bottom-Mounted ADCPs: These are ideal for long-term tidal studies and sedimentation monitoring. Choose devices in the range of 300–75 kHz based on channel depth.
• Buoy-Mounted ADCPs: These serve well for surface current monitoring in open waters near cruise terminals or offshore platforms.

Frequency Selection Guide

• 600 kHz: Shallow waters (<70 m) – High resolution for detailed near-shore studies.
• 300 kHz: Medium depths (70–110 m) – Balances range and precision for port channels.
• 75 kHz: Deep waters (up to 1,000 m) – For offshore approaches and deep-water cargo terminals.
