Ship digitalization, unmanned vehicle and cyber security

Paper

Public interest in autonomous ships has grown significantly since 2012, when the MUNIN project started to investigate the concept. In 2017, the first concrete project, Yara Birkeland, was published. Other projects are also under development. However, the business case for autonomous ships is not obvious: Benefits are no crew cost and no accommodation section or safety equipment for crew....

71. Launch and Recovery for Ship-Deployed Autonomous Underwater Vehicles

Deepsea mining and marine robotics

Paper

Autonomous underwater vehicles (AUVs) are increasingly being used for underwater survey and exploration missions. The expanding mission scope for AUVs highlights the need for a long-endurance operational capability, which mainly depends on propulsion efficiency and battery capacity. For most deployments, AUVs are launched and recovered from a mothership. While the launch process is relatively...

67. 3D Adaptive Coverage Planning for Confined Space Inspection Robots

Deepsea mining and marine robotics

Paper

The manual inspection of confined spaces, such as ballast tanks, for corrosion is a hazardous, time consuming, expensive, and subjective process. Robotic inspection techniques are being considered as they promise greater objectivity and comprehensive coverage as well as repeatability, reduced risk, and shorter maintenance downtime. To enable a robot to comprehensively inspect all surfaces...

29. Wetlands monitoring with innovative autonomous vehicles

Ship digitalization, unmanned vehicle and cyber security

Paper

Wetlands are geographic areas where water meets the earth. They cover between 5 and 8% of the Earth's surface. These include mangroves, bogs and marshes, rivers and lakes, alluvial plains and flooded forests, shallow coasts and coral reefs. They are essential ecosystems for human life. In fact, rich of life, these zones are very important sources of freshwater, but also natural purification...

186. Fastening of the data transmission in high latency satellite networks

Ship digitalization, unmanned vehicle and cyber security

The internet onboard of ships is very slow and uncomfortable. This is caused by the high latency of the used satellite networks. Most internet connections are based on connection-oriented protocols, like TCP/IP, which require positive acknowledgments for each data packet sent. To fasten the data transfer, the use of a connectionless protocol without positive acknowledgments would solve the...
