Abstract: A method for offshore load transfer and a floater for use in such load transfer are described. A hydraulic device for use in a horizontal positioning system for keeping the floater in position is also described. During the mounting and dismantling of large structures offshore, the floater will be exposed to wave and wind forces. By means of hydraulic jacks the floater is kept in a target position, within a horizontal frame. The jacks act as a positioning system and may also act as a sea fastening or sea securing system for the load when it is carried by the floater.

Abstract: A floater that is U-shaped in plan view for offshore load transfer is provided with storage/deployment apparatus for suction anchors. The suction anchors are placed in the seabed directly from the floater and are connected to the floater by adjustable tethers. The individual tethers are adjusted to attenuate relative motions between floater and seabed and to attenuate rolling motions of the floater during a load transfer.
