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 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.
