Description

[Detailed description of the invention] The present invention relates to a water rescue device and method.

More specifically, the present invention relates to a technique for rescuing people from extremely cold and dangerous sea areas, without the need for people to be rescued.

If a person falls from an offshore facility into the extremely cold dangerous waters of IF, the low temperature water will cause hypothermia very quickly. Typically, such hypothermia occurs in 8 to 15 minutes without a life jacket and about 45 minutes to a little over an hour with a life jacket on. After that, Tamamei is trying to figure out how to get the fallen person out of the sea as quickly as possible.

Existing equipment of nets, rafts and life preservers would prevent rescue boats from moving violently and removing people from the water without injury to the Horde's hull); Not useful. Furthermore, such equipment requires that a person who falls overboard has the ability to assist in saving his or her own life.

The present invention provides an apparatus for rescuing people from a crane, including a horizontally and vertically movable boom positioned on a rescue structure, such as an offshore rescue platform or boat.
1. 7. An elongate member is vertically movable and swingable relative to the boom, and flotation means are operatively connected to the elongate member to cause the elongated member to float on the water. A net extends below the flotation means and support means are provided below the flotation means.

When the person is in the water, the crane is deactivated to move the boom from an inboard position to an outboard position, and the elongate member is caused to move downwardly relative to the boom so that the flotation means floats in the water.

In this position, the tube 14 extends below the submersible lifting means. The K14 is moved forward by actuation of the boom (or boat or both) to allow a person to enter the K14. The crane operator then operates the boom to lift the person out of the water and onto the rescue structure.

Accordingly, the present invention allows rescuers to be scooped up without the need for their own help. Such rescues can be performed quickly and safely, thus increasing the rescued person's chances of survival.

Referring to FIGS. 1 and 2, a rescue device is shown having a flotation means 1, namely a float 15, floating freely on the water surface 20. Attached to the float 15 is an elongated member or pipe 10 of high tensile strength that slides within the guide 9. Frame 12 has four arms 22 extending vc outwardly from frame support bracket 17, which is connected to pipe 10.
