Kongsberg Marine Launches New LARS Solution

The new LARS solution benefits from the uniquely integrated combination of advanced in-house technologies which the KONGSBERG group offers, reinforced with years of accumulated expertise. After evaluating techniques and procedures in depth, Kongsberg Maritime has arrived at an optimal solution, namely to have the new LARS operating from midships, with the release and capture of HUGIN marine robots occurring beneath the sea surface.

Launching and recovering AUVs under water, away from the splash zone, lessens the possibility of their being damaged, while midships deployment averts any likelihood of AUVs being run over by the launch vessel. The new LARS’ subsea capabilities provide an extra benefit in that launch and recovery processes can be carried out in much higher sea states. This reduces the risk of weather damage to marine robots, while boosting productivity to deliver significant cost savings.

There are also tangible crew benefits. Operating the new LARS from midships will free up valuable aft deck space, and safety will be considerably enhanced as no personnel will be required to work over the stern in potentially challenging conditions. The design allows AUVs to be deployed from a hangar or container, and multiple robots may be managed from a single LARS. It is flexible with regards to placement – although midships is optimal – and can be operated from anywhere on board, including the stern. It may also be installed higher than on the main deck, to accommodate the vessel layout.

For deployment and recovery, the LARS cradle is lowered into the water to a pre-determined depth. It is positioned safely below the splash zone and propeller wash, enhancing both the weather window and safety, and is heave-compensated to stabilise the effect of waves and ship movement. Once in the water, HUGIN is released to start its mission. During recovery the AUV finds its way home to the cradle using the onboard navigation system and a KONGSBERG MicroPAP located in the LARS. Once nearby, the HUGIN drives itself into the cradle and is locked in before it is lifted out of the water.
