Introduction

The phenomenon of lost shipping containers at sea has been a topic of growing concern over the past few decades. These containers not only pose a risk to maritime navigation but also contribute to ocean pollution. In this article, we will explore the value of lost containers, their environmental impact, and the practicalities of recovering them.

Environmental Impact and Hazards

Lost shipping containers can be a significant hazard to maritime navigation and the marine environment. These containers often remain afloat for extended periods, posing a threat to smaller vessels and ships. One such experience occurred during a trans-Atlantic voyage, where a container washed ashore, causing extensive damage to the vessel and marine ecosystems. Cargo damage, collision marks, and overall structural issues are common findings in such incidents.

Case Study: Sunk Containers

Containers that sink typically become part of the marine landscape, affecting the seabed. Much of their value is lost as soon as they enter the water. The saltwater environment can degrade the seals and integrity of the containers, making them even more vulnerable to breaking and releasing their contents into the ocean.

Economic and Insurance Considerations

From an economic standpoint, the value of lost shipping containers is likely to be less than zero. Insurers will cover the loss, and depending on the contents, any salvage value is often negligible. It is also important to note that the retrieval process can often end up costing more than the value of the reclaimed items.

Recovery Operations

Recovering lost shipping containers is a complex and expensive process. For example, if a container is located at 5,000 feet, the operation would involve a sophisticated recovery spread including a seagoing flat transport barge, a large derrick barge, an ROV dive boat, ocean-going tugboats, retrieval boats, and a quarters/supply boat.

The recovery process involves several intricate steps:

Positioning the container using a crane attached to an ROV (Remotely Operated Vehicle). Lifting the container using a balloon filled with compressed gas. Floating the container to the surface using compressed air. Picking up the container and placing it on a transport barge.

This process is logistically challenging and can be extremely expensive, typically costing between $50,000 to $100,000 per container.

Ownership and Legal Considerations

The ownership of lost shipping containers can be complex. In many cases, the container's contents and the container itself become government property due to the high cost of recovery. Maritime law and international conventions play a crucial role in these scenarios, often dictating that the cost of recovery justifies the seizure of the container and its contents.

Conclusion

While the economic value of lost shipping containers is often negligible, their environmental impact cannot be understated. The recovery process is fraught with challenges and significant costs. For both environmental and logistical reasons, the focus should be on preventing these losses in the first place.
