South Korea Transformed an Exposed Bay into a Deep Water Port by Dredging 72 Million m³ of Sediments and Raising Colossal Maritime Structures to Compete in Global Trade.
According to official documents presented by South Korea’s Ministry of Finance at APEC forums, the country dredged approximately 72 million cubic meters of sediments at the beginning of the development of Busan New Port, one of the largest maritime engineering projects in Asia. The goal was to create a deep-water port infrastructure capable of accommodating the largest container ships in the world, expanding South Korea’s logistical capacity and repositioning the country in global maritime trade.
The originally chosen area was not a natural port. It was an exposed region to open sea, with insufficient depths, wave hazards, and no coastal infrastructure. To make it viable, South Korea needed to excavate channels, deepen port berths, stabilize the seabed, erect retaining walls, shape artificial islands, and then build an entire logistical ecosystem on this new maritime territory.
This process defines what engineers call a “constructed deep-water port”, different from traditional ports that take advantage of natural inlets or bays.

Industrial Dredging on a Continental Scale
Dredging 72 million m³ would already be an achievement in itself, but the impact goes beyond the raw number. In practice, this means:
- Removing sediments to create deep drafts for Post-Panamax and New-Panamax ships
- Ensuring adequate depths even in choppy seas and seasonal waves
- Keeping the channel navigable year-round
For comparative purposes:
• 72 million m³ is equivalent to filling about 28,800 Olympic-sized swimming pools
• It is larger than the volume of sediments removed in some European megaprojects
• It was carried out in an oceanic environment, which multiplies the complexity
All of this involves suction dredges, marine excavators, hydraulic transport systems, and rigorous environmental monitoring to ensure that none of this destroys sensitive biological areas near the port.
Construction of Maritime Walls, Dikes, and Platforms
With the seabed prepared, the structural phase came: erecting a port where there was none. This meant:
• Building marine retaining walls with cyclopean blocks and rock armor
• Creating interconnected logistical islands and industrial platforms
• Stabilizing docking areas with deep foundations
• Installing breakwaters that reduce waves and enable 24-hour operations
These works are comparable to Japan’s large offshore port projects, with one fundamental difference: Busan’s goal was to compete with Shanghai, Singapore, and Yokohama, which are among the largest logistical hubs in the world.
A Port Designed for Global Trade
The strategic choice was not casual. There is a powerful economic reason: about 90% of global trade is transported by sea and logistical bottlenecks define who profits, who loses, and who grows. The Busan New Port was born to:
- Accommodate Ultra Large Container Vessels (ULCV) with over 20,000 TEUs
- Serve as a transshipment hub for the Pacific and Indian routes
- Reduce dependence on external ports
- Increase South Korea’s logistical autonomy
Today, Busan is among the largest ports on the planet in terms of annual container movement and acts as a multiplier effect on the Asian economy.
Maritime Engineering as a Geopolitical Tool
Projects of this magnitude rarely deal solely with engineering. They shape trade relationships, industrial chains, bilateral agreements, and even a country’s position on the international stage.
The Busan New Port:
- Attracted industrial clusters throughout the region
- Accelerated logistics agreements with the United States, Europe, and Southeast Asia
- Encouraged foreign investment in special economic zones
All of this because South Korea realized early on that container ships do not wait for lagging countries, and maritime logistics has become a form of economic sovereignty.
