Subsea hull maintenance for ships crossing the Panama Canal: The key to avoiding delays and additional costs

The Panama Canal is one of the most important trade routes in the world. Thousands of ships pass through this canal every year, carrying goods of all kinds, from raw materials to manufactured products. However, in order for this activity to flow smoothly and efficiently, it is crucial that the vessels maintain optimum condition, especially with regard to the hull. Subsea hull maintenance is not only an essential practice, it is also the key to avoiding unnecessary delays and additional costs.

In this article, we will explore the importance of hull maintenance for ships crossing the Panama Canal, the risks of not performing it, and how a good maintenance program can save shipping companies millions.

The importance of the Panama Canal to world trade

The Panama Canal is a vital crossing point for global trade routes. This waterway connects the Atlantic Ocean to the Pacific Ocean, allowing ships to significantly shorten their travel time. However, due to the constant traffic of vessels and the characteristics of the canal, the hulls of ships are subjected to considerable wear and tear.

The unique conditions of the Panama Canal, such as variations in water salinity, the presence of marine organisms and the constant friction with the water, can cause the accumulation of biofouling (fouling of marine organisms on hulls). If left unchecked, this can seriously affect the vessel’s performance.

What is biofouling and how does it affect ships?

Biofouling is the accumulation of microorganisms, plants, algae and small animals on the surface of a ship’s hull. This build-up occurs naturally when a ship is in the water for a prolonged period of time, and is more common in warm waters such as those of the Panama Canal. The problem with biofouling is that it increases the resistance of the hull as it moves through the water, which in turn increases fuel consumption.

In addition to increased fuel consumption, biofouling can cause long-term damage to the hull structure and other ship components, which increases maintenance and repair costs. More worryingly, an unmaintained hull can become an environmental problem, as invasive organisms transported from one side of the channel to the other can negatively affect marine ecosystems.

How does underwater hull maintenance help avoid these problems?

Underwater hull maintenance consists of cleaning and repairing the surface of the ship’s hull while it is submerged. This type of maintenance is essential to maintain the performance and efficiency of the vessel, especially when frequently navigating in areas as active as the Panama Canal.

The advantages of proper underwater maintenance are multiple:

1. reduced fuel consumption: regular cleaning of the hull eliminates biofouling, which allows the vessel to sail with less resistance and, therefore, consume less fuel.
2. Prolonged vessel life: By keeping the hull clean and free of damage, the possibility of metal corrosion or excessive wear is reduced, which prolongs the vessel’s life and reduces the need for costly repairs.
3. Operational Efficiency: A vessel with a hull in good condition can meet scheduled transit times and deadlines through the Panama Canal, avoiding delays that can result in fines or penalties from Canal authorities.
4. Reduced environmental impact: By reducing the transport of marine organisms from one region to another, underwater hull maintenance helps preserve the ecosystems in and around the canal.

When is underwater hull maintenance required?

Vessels that frequently transit the Panama Canal must undergo underwater maintenance on a regular basis. Experts recommend that vessel hulls be cleaned every six months, although this can vary depending on factors such as the type of vessel, the amount of traffic, and the environmental conditions in which it operates.

Some signs that indicate the need for immediate underwater maintenance include:

• Increase in fuel consumption with no apparent cause.
• Reduction in vessel speed.
• Visible accumulation of biofouling.
• Hull damage or dents caused by impacts with submerged objects or structures.

The Panama Canal Subsea Maintenance Process

The underwater maintenance process involves a combination of inspection, cleaning and, in some cases, repair. Companies specializing in this type of work, such as Aquadiver Panama, use certified divers and advanced technology to ensure that the hull is in the best possible condition.

1. Underwater inspection: Before cleaning begins, divers conduct a detailed inspection of the hull to identify critical areas that require special attention. This may include detection of damage, corrosion or excessive biofouling.
2. Hull cleaning: Using specialized tools, divers remove accumulated biofouling from the hull surface. Depending on the severity of the build-up, this process may take several hours.
3. Minor repairs: In some cases, divers may perform minor repairs to the hull, such as sealing small cracks or applying temporary patches.
4. Final Report: Once the maintenance is completed, the dive company provides a detailed report to the vessel owner, indicating the general condition of the hull and any recommendations for future maintenance.
