1 What Are Maritime Autonomous Surface Ships (MASS)?

MASS are vessels that can operate with varying levels of human interaction, ranging from remote control to fully autonomous operations. These ships are equipped with advanced navigation, propulsion, and decision-making systems that allow them to perform tasks independently or with minimal human input. While the concept of autonomy in shipping is relatively new, it promises to increase efficiency, reduce human error, and improve safety across the maritime industry.

Levels of Autonomy in MASS:

Level 1: Ship with automated processes and decision support (still crewed).
Level 2: Remotely controlled ship with crew onboard.
Level 3: Remotely controlled ship without crew onboard.
Level 4: Fully autonomous ship, capable of making all decisions independently.

How MASS Works

MASS technology relies on several cutting-edge systems, including artificial intelligence (AI), sensors, automation, and communication networks. These technologies allow the vessel to perform tasks like navigating, detecting obstacles, responding to weather changes, and managing cargo autonomously.

AI and Machine Learning: These technologies help MASS analyze data and make decisions in real-time. For instance, AI can interpret radar and sonar data to avoid collisions or determine optimal routes.
Sensors and Cameras: Sensors such as radar, LIDAR, and sonar provide situational awareness, feeding data into the ship’s navigation systems to map the surroundings.
Communication Systems: MASS relies on satellite communication and secure networks to transmit real-time data between the vessel, shore stations, and, in some cases, other vessels.

Technical Example:

A Level 3 MASS, remotely controlled from a shore control center, can navigate through a busy shipping lane using real-time data from its onboard sensors. The AI onboard interprets weather data to determine the safest route, while the control center provides additional oversight.

2 Historical Development of MASS

The concept of autonomous ships has been discussed for decades, but significant technological advancements in recent years have brought MASS closer to reality. The International Maritime Organization (IMO) has been actively working on regulations to integrate MASS into the global shipping framework.

Key Historical Milestones:

2010: Early discussions about autonomous ships begin, focusing on reducing crew fatigue and human error.
2017: The IMO begins developing an international regulatory framework for MASS.
2018: Rolls-Royce launches YARA Birkeland, the world’s first electric, autonomous container ship, designed to operate without a crew.
2020: The IMO launches a regulatory scoping exercise to analyze existing conventions and how they apply to autonomous ships.

YARA Birkeland - the world’s first electric, autonomous container ship

YARA Birkeland is an innovative electric container ship developed by the Norwegian company Yara International. Launched in 2021, it is designed to be fully autonomous and aims to revolutionize the transportation of goods by reducing emissions and enhancing sustainability in maritime shipping. The vessel measures 80 meters in length and can carry up to 120 containers. YARA Birkeland operates primarily in Norway, transporting fertilizers from Yara's production facility to ports, thus eliminating around 40,000 truck trips annually. Equipped with advanced navigation systems, the ship is expected to operate with minimal human intervention, representing a significant step toward greener shipping practices and the future of autonomous maritime transport.

3 Features of MASS

3.1 Autonomous Navigation

MASS can make real-time navigational decisions based on input from sensors, cameras, and other data-gathering technologies. For instance, the ship can autonomously determine its route, avoid obstacles, and respond to dynamic environmental conditions like fog or rough seas.

3.2 Reduced Crew Requirements

One of the major selling points of MASS is the reduced need for onboard crew. Depending on the level of autonomy, a MASS may either have fewer crew members or operate without any human personnel onboard. This feature has the potential to lower operating costs and eliminate risks associated with human error.

3.3 Advanced Communication Systems

MASS vessels use advanced communication networks to relay real-time data to shore control centers or other vessels. This helps facilitate the remote monitoring and control of the ship, especially for Level 2 and Level 3 autonomous vessels.

3.4 Integration with Digital Navigational Systems

MASS systems are designed to work in conjunction with modern navigational tools like ECDIS, radar, and AIS (Automatic Identification System), ensuring seamless navigation in both open waters and congested shipping lanes.

4 Advantages of MASS

4.1 Increased Efficiency

With the automation of many tasks, MASS can operate around the clock without fatigue-related downtime. These ships can also optimize fuel usage by calculating the most efficient routes in real-time.

4.2 Improved Safety

By reducing human involvement, MASS can minimize errors caused by fatigue, misjudgment, or lack of experience. Autonomous systems can also respond more quickly to sudden changes in the environment, such as weather or traffic.

4.3 Cost Reduction

The reduction or elimination of crew members leads to significant savings in terms of wages, living expenses, and insurance costs. Additionally, MASS vessels can be designed without crew quarters, reducing the weight and increasing cargo capacity.

4.4 Environmental Benefits

MASS often employ advanced propulsion technologies, such as electric engines or hybrid systems, which can significantly reduce greenhouse gas emissions and fuel consumption.

5 Disadvantages of MASS

5.1 High Initial Costs

The development and deployment of MASS require significant capital investment. The costs associated with building these vessels, installing advanced navigation systems, and developing robust communication infrastructure can be prohibitive for many shipping companies.

5.2 Cybersecurity Risks

As MASS relies heavily on digital systems and communication networks, these vessels are susceptible to hacking and cyberattacks. The maritime industry must develop advanced cybersecurity measures to protect autonomous ships from these threats.

5.3 Regulatory Challenges

The existing international maritime laws are not fully adapted to autonomous vessels, which creates regulatory uncertainties. The IMO is currently working on frameworks, but the process is slow and complex.

5.4 Limited Adaptation

Smaller shipping companies may find it difficult to adapt to MASS technology due to the high costs and complexity. The technology is also not fully proven for long-range, international voyages, limiting its current application.

6 MASS and ECDIS Integration

Electronic Chart Display and Information Systems (ECDIS) are critical for the safe navigation of MASS. ECDIS provides digital nautical charts and integrates with other navigational aids like GPS and radar, giving MASS real-time situational awareness.

How ECDIS Supports MASS Operations:

Navigation and Route Planning: ECDIS is used to plot and monitor a vessel’s course, ensuring that the autonomous ship follows safe and legal routes.
Collision Avoidance: ECDIS helps MASS identify and avoid other vessels, submerged obstacles, and restricted areas by combining AIS data with real-time sensor information.
Automated Updates: ECDIS can receive real-time updates on nautical charts, allowing autonomous vessels to adjust their routes as necessary.

Technical Example:

A fully autonomous cargo ship operating in the North Sea uses ECDIS to navigate congested shipping lanes. The ship's AI is constantly analyzing ECDIS data to adjust its course, avoiding fishing vessels, oil rigs, and buoys. Additionally, ECDIS updates its charts with the latest depth soundings and hazards, ensuring safe navigation through shallow waters.
