Why Do Cargo Ships Often Have Red Painted Decks and What's the Purpose Behind It?

Have you ever noticed the distinctive red painted decks on cargo ships? You might have wondered why they are painted this color. While the answer may seem mundane, the history behind it is quite intriguing. This article delves into the reasoning behind red-painted decks in cargo ships.

Historical Context of Red Painted Decks

In the 1700s, the British Navy painted the decks of some of their warships in red to help disguise the flow of blood in battle. This practice was more a matter of psychological warfare than practical camouflage. However, the tradition has survived through the years, particularly in the field of cargo ships.

Nowadays, the primary reason for using red paint on the decks of cargo ships is practicality and durability. Red paint is a type of oxide paint, which is cheap and quite durable, making it a popular choice among ship owners who want to extend the life of their ships without spending too much on maintenance.

The Process of Red Painting On Deck

Applying red paint to the decks of cargo ships is a labor-intensive process. Here’s a step-by-step account of what goes into it:

Surface Preparation: The first step is to remove any rust from the metal surface. This is done by chipping, where the crew use tools to chip off the rust. The next step is wire brushing the metal surface to smooth it out. Painting: After the surface is prepared, the red oxide paint is applied. It is thick and non-flowing, allowing for an even application. This is a crucial step as an uneven application can lead to peeling over time. Maintenance and Repainting: Cargo ships require frequent repainting due to constant exposure to the harsh marine environment. The paint starts to wear off due to saltwater, wind, and marine life. Regular maintenance is essential to ensure the longevity of the ship and the safety of the crew.

Red paint is applied to the entire deck, but occasionally, for a change of pace, the first officer might have the crew paint the deckhouses or ladders in white. This variety can provide a refreshing change from the incessant routine of red, but it ultimately returns to the standard red.

Challenges in Maintaining Red Painted Decks

Maintaining the red-painted decks is not without its challenges. The constant chipping, brushing, and repainting can be soul-destroying for the crew, leading to a repetitive and monotonous task. However, the importance of a well-maintained deck cannot be understated. A rusty deck not only looks unsightly but also poses safety hazards to the crew and passengers.

Red-painted decks in cargo ships are a testament to their practicality and the ingenuity of the maritime industry. While the practice may seem outdated, it continues for good reason. The historical significance and the practical benefits make it a tradition that is unlikely to fade away anytime soon.

Conclusion

In conclusion, the red-painted decks on cargo ships are not just aesthetically pleasing but are vital for the safety and longevity of the vessel. Understanding the historical and practical reasons behind this tradition can enhance our appreciation for the maritime industry's efforts in maintaining safe and efficient shipping operations.
