Lifting the cut sections

A floating sheerleg is used to raise the cut

sections from the seabed

Workers cut holes

to attach lifting

cables

The cut sections are

loaded on to barges

and towed to shore

Floating the stern

Enormous air-filled metal boxes called caissons

are welded to the sides of the hull

The caissons are filled

and emptied of water

to right the hull and

reach the perfect level

of buoyancy

Once righted and

afloat tugs tow

the stern to shore

Clearing debris

Barges fitted with

underwater magnets

and grabbers pick up

smaller debris on site

Sections removed and taken ashore
