1. A module-based system (400) for material handling in connection with plug and abandonment operations of wells on an offshore installation comprising an upper main deck in the form of a main rig (230) and skidding deck and at least one lower deck (240-250) with limited available lifting height, comprising:
modules (100, 110, 120, 130, 140, 150, 160, 170, 180, 200, 210) configured to allow operation independently from a main drilling tower or external rigs on the upper main deck of the offshore installation, wherein
the module-based system (400) is adapted and installed at the lower deck (240) of the offshore installation by a frame module (100) acting as a foundation for the other modules (100, 110, 120, 130, 140, 150, 160, 170, 180, 200, 210), said frame module (100) having a telescopic extension to adjust a height of said frame module (100) to the available lifting height, and
the module-based system (400) is configured to perform all material handling operations in connection with the plug and abandonment operations via a lift module (210) and integrated material handling modules comprising a transport trolley module (130), a pipe manipulator module (160), a jack module (170) and a winch module (200) interchangeable with one another.
