Cable-lay vessels tend to share some common characteristics, most notably large, flat decks and wide beams to accommodate heavy, large-diametre carousels. It is a functional layout, but one that comes with trade-offs — a high centre of gravity, for one, and less than optimal seakeeping.

Ulstein’s new LX109 cable-lay vessel design aims to address those issues while significantly extending the amount of cable that can be installed in a single piece.
