What is a Maritime Drone?

The term "maritime drone" refers to remote-controlled devices used in the maritime industry. These drones can be aerial UAVs or underwater ROVs, but this article will focus on airborne applications, which are more common and widely used.

Maritime drones have gained significant traction in recent years. In 2021, the European Maritime Safety Agency (EMSA) awarded a €30 million contract to TEKEVER for aerial surveillance of European waters. This highlights the growing reliance on these tools across global maritime operations.

Drones are versatile and adaptable, making them ideal for various marine tasks. As their use becomes more widespread, more countries and organizations are likely to integrate drones into their fleets for enhanced efficiency and safety.

What Are Maritime Drones Used For?

Maritime drones are deployed in environments that are dangerous, confined, or difficult for humans to access. They help reduce risks, save time, and improve the accuracy of inspections and monitoring tasks.

Let's explore some of the key applications:

Cargo Hold Inspections

Cargo holds are often challenging to inspect due to their size, limited access, and potential contamination. Drones can quickly scan these areas to detect issues like rust, paint peeling, or residual materials, ensuring compliance with strict regulations.

Common contaminants include grains, feed, soil, and sand, which can lead to failed inspections if not addressed. Using drones significantly improves safety and reduces downtime for ships.

Engine Room Inspections

Fire outbreaks in engine rooms can be extremely hazardous. Drones like the Elios 3 can safely enter such areas to confirm that fires are fully extinguished and assess structural integrity. This allows firefighters to respond more effectively and safely.

Ballast and Fuel Tank Inspections

Inspecting ballast and fuel tanks is both time-consuming and risky. Drones can complete these inspections in a fraction of the time, reducing costs and improving data accuracy. They also enable more frequent checks, enhancing the longevity of critical ship components.

Port and Ship-to-Shore Crane Inspections

Large cranes require regular maintenance, but manual inspections are costly and dangerous. Drones make it easier to identify structural issues and plan repairs without putting workers at risk.

Security and Surveillance

Drones are increasingly used for border security, anti-fishing patrols, and monitoring water pollution. With advanced sensors, they can detect illegal activities and enhance situational awareness in vast maritime zones.

Search and Rescue

Maritime drones are now being used for search and rescue missions. They can quickly locate individuals in distress and deploy life-saving equipment, improving response times and reducing risks for first responders.

Drone to Ship Deliveries

Delivering essential supplies to ships at sea is expensive and time-consuming. Drones offer a cost-effective alternative, enabling quick and efficient deliveries without requiring ships to return to port.

Benefits of Using a Maritime Drone

Maritime drones provide numerous advantages, including:

  • Reduced downtime for ships and critical infrastructure
  • Improved safety by minimizing human exposure to hazardous environments
  • Significant time and cost savings in inspections
  • More accurate and detailed inspection results
  • Enhanced efficiency through frequent and reliable monitoring
  • Improved security and border control capabilities
  • Faster search and rescue responses
  • Efficient delivery solutions for ships at sea

Case Studies of Maritime Drone Services

Maritime drones are transforming how inspections and operations are conducted. Here are a few real-world examples of their impact:

Saving 15,000 Hours with a Maritime Drone

A mid-sized ship used a drone to inspect oil tanks, eliminating the need for scaffolding and saving over 15,000 hours of labor. The drone completed the task efficiently and was accepted by the class society.

Marine Drone Services Save $1 Million

A vessel used a drone for a hull inspection, cutting costs and improving safety. The results were certified by the American Bureau of Shipping, proving the effectiveness of drone technology.

Oil Tank Inspections on an FPSO

A floating production, storage, and offloading vessel used drones to inspect oil tanks in just four days, compared to the traditional two-week process. This improved efficiency and reduced risks for personnel.

Inspecting 63 Tanks in Two Weeks

A rig off the coast of Brazil used drones to inspect 63 tanks in just 14 days, significantly reducing the number of people required on board and improving operational efficiency.

Types of Maritime Drones

Selecting the right drone depends on whether the application is indoor or outdoor. Here are some of the most popular models:

Indoor Maritime Drones

Flyability Elios 3

The Elios 3 is designed for inspecting confined spaces. Its spherical design and advanced software allow safe navigation through ballast tanks, cargo holds, and engine rooms. It features dual thermal cameras, powerful lighting, and modular payload options.
