Abstract
A free fall, submersible life saving device for an offshore structure has a spherical pressure shell in a casing. The upper part of the device has a lifting frame and at least one manhole closed with a cover and the lower part has ballast, an anchor, and a windlass 5 for the anchor rope having automatic control of the tension in the anchor rope. The device is launched by a catapult on the offshore structure for horizontal movement in free fall to the water surface, where it submerges and is anchored until resurfacing, by release of the anchor, for rescue.
