SW Thuridur — Ulstein SX134 X-BOW · Turnkey Conversion to DP2 Fibre-Optic Repair Vessel
A short path to a working repair ship, delivered by Dimension as a turnkey conversion through partner shipyards, with leading vendor support across the mission spread. Already DP2, with a complete bow, stern and azimuth thruster set and Ice(1A) for northern work — ≈1,600 t of cable in a below-deck tank, and the complete fibre-optic mission spread supplied new.
Teal-flagged items in the specification below denote new or modified equipment within the conversion scope.
The SX134 needs no thruster package before it can work, which keeps the conversion scope short and the route to a first contract direct. The whole fibre-optic mission spread is supplied new.
