The evaluation and improvement of the hydrodynamic behaviour of mechanically coupled barges: A novel decommissioning method for oil and gas platforms in the North Sea

Allseas' Pioneering Spirit is the largest heavy lift vessel in the world. It uses its u-shaped bow to sail around an offshore platform and lift topsides up to 48.000t in a single lift. Despite being the largest vessel in the world, platforms exist that are simply too heavy, or too large to fit in between the bows of the vessel. Besides, smaller...

Mooring lines and fenders are installed to keep the vessels in place. Experience has shown that lines tend to break occasionally; one of the reasons for this can be the interaction effect of the two vessels...
