Abstract

A method of carrying out operations under the surface of a body of water, which comprises securing at least one flexible cable at one end thereof to a fixed point below the surface of the body of water, securing the other end of the cable to platform means intended to catch the cable, which platform is secured to a ship such that it can move in at least a substantially vertical direction relative to the ship, applying a substantially constant force between the platform and the ship's such that the force acting on the platform is directed upwards and the cable is tensioned such that the load on the flexible cable is equal to the force applied between the platform and the boat minus the weight of the platform and the equipment carried by it, and carry out operations from the platform below the surface of the body of water.
