ABSTRACT:
A device for lifting a seagoing construction such as a drilling rig, which device comprises one or more floater bodies, one or more beam-like lifting members supported movably on a floater body and running parallel or practically parallel to each other, wherein the or each lifting member is supported on at least two support points of the floater body, at least one of which is adjustable in height direction, and the end part of the lifting member lying outside the floater body has a pressure point which is in contact with the construction for lifting, this such that the seagoing construction can be easily connected to the end of the lifting member without this construction suffering damage as a result of the sea swell.
