ABSTRACT:
An offshore lifting construction is able to control buoyancy for the lifting of jackets for offshore platforms. The lifting construction is designed such that it can be ballasted for raising and lowering and such that it can take several positions. The lifting construction is designed as an arm equipped with a joint for attachment to a vessel. The arm includes two substantially parallel longitudinal elements with intermediate supporting elements. One of the ends of the arm includes at least two tubular branches substantially perpendicular to the longitudinal direction of the substantially parallel longitudinal elements. At least one of the elements of the arm includes at least one ballastable tank. The arm is equipped with device for attachment to the jacket that is to be lifted. A method for rising jackets or jacket legs for offshore platforms is also described.
