Unmanned Surface Vessel (USV) handling

The LARS' configuration allows to safely catch and release bigger and heavier mission boats without requiring human actions, making it the perfect system to handle Unmanned Surface Vessels.

Manned Mission Boat handling

Creating a cradle-like situation behind the mother vessel, the system catches the manned mission boat without requiring direct involvement of the crew, safeguarding them in all operating conditions.

Unmanned Underwater Vehicle (UUV) handling

The system's double-outboard rolling frame and the design of the landing frame are adaptable to handle underwater-type vehicles safely, catching and securing these vehicles in a submerged situation.



The launching and recovering of mission boats and other crafts from the stern of a mother vessel is performed in the wake of the mother vessel, which is with the right heading and speed a safe area for daughter craft handling. Conventional means, handling the craft alongside the vessel, are more subject to hazardous situations created by the waves and require manual means of connecting catch hooks.

The LARS' double outboard rolling frame configuration with buckling unit allows the landing frame to immerse partially below water, which in combination with the main frame create a cradle-like situation behind the mother vessel. In this situation, and considering the data on the waves in the stern-wake area behind the mother vessel, the crafts can sail in (or out) safely and catch (or release) themselves wiithout requiring hazardous actions from the crew.

The system protects the crafts from damages in stowage and during operations by adapting the shapes and locations of all fenders and buffers in the main and landing frames to the shapes, weights and other characteristics of the craft. In addition, the system catches or releases the mission boat or other craft when it is floating outside the mother vessel, by which there is controlled situation in which catching and releasing takes place.

The system can be applied both in existing and newly designed vessels. The interfaces of the system are designed in close collaboration between the naval architects or shipyard and TBV. Moreover, the configuration of the LARS can be adapted to the situation, for example by integrating a pivoting base frame that allows for pivot the complete system between its operating and stowing positions.

The LARS is applied to handle crafts up to 14 meters in length, with a weight of 12.5tonnes. For lengths and weigths exceeding this, TBV's team reviews the requirements on a case by case basis.
