The present invention relates to a unit (1) for offshore application, comprising a deck (2) equipped with a crane (3) with an articulated boom (4). which crane (3) comprises: a support structure (5), secured to said deck (2), and an articulated boom (4), carried by said support structure (5).

The articulated boom (4) comprises a main boom (41) and a terminal boom (42), in series, which terminal boom (42) has a head (422) at the opposite side of said support structure (5).

This deck (2) is equipped with a cradle (10), at a distance from the support structure (5), which comprises a receiving portion (101) on which a head (422) of said terminal boom (42) is intended to rest in said rest position.

A method for transporting a workpiece from an initial work cell to a subsequent work cell in a manufacturing environment having a plurality of work cells, the workpiece is supported by a support beam. The method includes monitoring the initial work cell for presence of a ready-to-move condition and monitoring the subsequent work cell for presence of a ready-to-receive condition. When both the ready-to-move condition and the ready-to-receive condition are present, the method includes interfacing the support beam with a gantry and, after the interfacing, moving the support beam with the gantry from the initial work cell to the subsequent work cell.
