ALR-C for
Davit & Crane
Maritime launch and recoveries via cranes or davits are standard practices. ALR-C, a fully autonomous system, streamlines retrievals of USVs and manned boats in varying sea conditions with minimal human intervention.
With rapid capture (<1.5 sec) and hauling (<15 sec) times, ALR-C ensures swift operations. Its fully autonomous capture initiation and recovery sequence, optionally manual, guarantee reliable performance.
Equipped with innovative identification and capture systems, ALR-C performs the entire recovery sequence automatically. As an add-on for ships or rigs, it requires minimal modification, enabling seamless integration on existing or new vessels.

the challenge of side recoveries
Side recoveries are commonly practiced in the maritime sector, necessitating a proficient crew both on the boat and the hosting ship. The complexity and risk of the procedure escalate with higher sea states. Relying heavily on human expertise often results in accidents, causing injuries and, at times, casualties. These incidents contribute to restricted operational capability in varying sea conditions, impacting both civilian and defense markets.
This challenge is particularly pronounced for Unmanned Surface Vehicles (USVs). With no crew on board, the primary hindrance lies in connecting the USV to the ship’s crane or davit systems, posing a significant obstacle to the integration of USVs in the maritime domain.
Examples of manned recoveries gone awry include…
