Navy Large Vessel Interface Lift On Lift Off
Navy’s Large Vessel Interface Lift On/Lift Off (LVI Lo/Lo) crane loads and unloads safely in meter high waves…
The U.S Navy has developed a new crane rig that is able to transfer cargo at sea whilst compensating for surging waves, effectively eliminating the need for a sheltered harbor in emergency or combat situations.
Most ships need a protected port with calm waters to prevent cargo from swinging violently while being transferred. However, the Navy’s new Large Vessel Interface Lift On/Lift Off (LVI Lo/Lo) crane is fitted with an array of cameras and sensors, as well as motion-sensing algorithms that enable it to adjust automatically depending on the roll of the waves.

In recent trials, the LVI Lo/Lo, developed by the by the Sea Warfare and Weapons Department of the Office of Naval Research along with Oceaneering International, successfully transferred 128 containers from one ship to another amid waves of up to 1 meter (3.28 feet).
Not only does the LVI Lo/Lo offer a safe method of cargo transfer without the need for a deep-water port, it does so with less man power. Standard cranes require a team of ten to move heavy cargo such as 20-foot containers and Humvees, the LVI Lo/Lo only requires three – one in the crane house and one on each ship.
Although the future development and use of the crane is still unclear, a demonstration version of it is installed on the SS Flickertail State, a crane ship based in Newport News, Va. And according to ONR, the crane is available to support U.S. humanitarian assistance and disaster-relief operations.
