A motorized lifebuoy

At METSTrade 2019, USafe presented an innovation for safety at sea that won over the jurors of the DAME Award. Similar to a cross between a life ring buoy and a hydrospeed, this new remotely operated safety equipment allows the recovery of boaters or swimmers in difficulty. Self-propelled and remotely controlled, the drone provides support to the person who has fallen into the water that the pilot can then bring back safely.

Rescue the boater quickly

Equipped with two thrusters and a battery-powered electric motor, the USafe buoy can reach a maximum speed of 15 km/h for 30 minutes. It has a weight of 13 kg equipped.

The propellers and their water intakes, housed in the 2 arms of the USafe buoy, operate in both directions. An internal sensor reverses the direction of rotation in the event of the buoy being turned over by a wave. Fully integrated, the propellers do not present any danger to the rescued person.

Two pairs of handles allow the rescued person to hold firmly.

A slot in the buoy holder holds the remote control, equipped with a simple joystick. Its induction charging prevents any connection errors and ensures that it is charged in case of emergency.

Use from land or boat

The USafe buoy has been designed for several types of use. From land, it can be remotely controlled by lifeguards to reach a swimmer in difficulty as quickly as possible. Installed on the balcony of a large pleasure boat or on professional installations such as oil platforms or wind turbines, it allows you to recover the person who has fallen into the sea.
