摘要

An arrangement for retrieving a laydown head to a surface vessel from a pipeline end section that is secured to a pipeline termination skid at the seabed. The arrangement is detachably mountable to the pipeline termination skid and comprises a base frame configured to bear against the pipeline termination skid when the arrangement is mounted to the pipeline termination skid; and one or more rigid supporting units provided on the base frame for supporting the laydown head from below, each supporting unit comprising an upwardly directed seat for receiving the laydown head and an actuating device for moving the seat in the vertical direction. Embodiments of the present invention also relate to a system comprising such an arrangement and a pipeline termination skid, and a method for retrieving a laydown head by means of such an arrangement.
