METHOD AND DEVICE FOR REPLACING EQUIPMENT ON THE SEABED

摘要

The invention relates to a device (20) for replacing equipment, i.e. modules on an installation (10) on the seabed. The device comprises a box-shaped buoyancy element which has storage spaces (25) for equipment together with winch devices (22) assigned to each storage space. During use the device is lowered from a vessel (1) to the seabed by means of a crane (3), but is stopped a distance from the installation, whereupon the locally provided winches (22) are used to pull up and position the equipment.
