The Future of Launch and Recovery Systems in Subsea Operations

Launch and recovery are critical aspects of subsea operations, often posing significant risks. According to iDROP COO David Galbraith, the value of subsea vehicles increases during recovery due to the wealth of new data they carry.

iDrop faces the challenge of efficiently launching and recovering large numbers of its autonomous ocean bottom nodes (OBNs). Unlike traditional methods that require specialist vessels and crews, iDrop’s Oceanid™ drones are designed to self-steer to the seafloor without the need for ROV assistance or DP-capable mother vessels, simplifying the recovery process.

Challenges and Solutions for Launch and Recovery Systems

Seth McCammon from Woods Hole Oceanographic Institution emphasizes the need for flexible and scalable launch and recovery systems for swarms of subsea vehicles. He suggests a two-tiered approach, with larger autonomous platforms capable of recovering smaller, less advanced vehicles.

McCammon is developing a net system for autonomous surface vessels to recover swarm AUVs efficiently. This scalable solution relies on the advanced capabilities of the larger platform to retrieve multiple AUVs after completing their missions.

Companies like Exail and Kraken Robotics are also innovating in this space with modular and intelligent LARS solutions. These systems offer autonomous features, remote monitoring capabilities, and enhanced safety measures for launching and recovering subsea vehicles.

Advancements in Launch and Recovery Technology

DeepOcean’s patented LARS for the USV Challenger enables seamless launch and recovery operations while the vessel remains in motion. The integration between the vessel, its remote systems, and the ROV optimizes reliability and safety during operations.

AXTech’s Smart Tower Solution provides a flexible and modular approach to launching and recovering subsea modules, offering multiple operational options without the need for extensive vessel modifications.

Researchers at KTH are exploring aerial LARS technology in collaboration with Saab, using autonomous aerial drones to deploy and retrieve underwater vehicles with precision and efficiency. This innovative approach aims to enhance vehicle deployment speed, reduce risks to human operators, and enable real-time decision-making through AI-powered systems.

Conclusion

The evolution of launch and recovery systems in subsea operations is paving the way for safer, more efficient, and scalable solutions. With advancements in autonomy, robotics, and AI, companies are revolutionizing how subsea vehicles are deployed and recovered, ultimately enhancing the success and sustainability of underwater missions.
