80-Metre Ice-Class UT 722 Construction & Rescue AHTS — Conversion
262 ft (80 m) · Rolls-Royce UT 722 · Built 2003 · DNV Ice-Class
A Rolls-Royce UT 722 anchor-handler and offshore-construction hull — heavy North Atlantic pedigree, engineered for the worst weather afloat.
Built for subsea construction — a heavy offshore crane, ROV and dive spreads, and a vast aft working deck already aboard.
An ice-classed steel hull rated for high-latitude operation — polar capability engineered in, not retro-fitted.
A rescue-rated standby vessel with active helicopter operations — a working platform for expedition logistics.
An offshore-construction AHTS is the most capable canvas afloat — heavy lift, subsea handling and ice class already engineered into the hull.
Standard capability is built into the hull today; optional systems are engineered in during conversion.
A conversion is far more than a technical upgrade. It is the transformation of a proven, ocean-tested hull into a yacht with new purpose, new value and a life of its own — and it rewards the owner who can see what others cannot.
The hull, machinery, ice class and subsea capability are proven. The conversion re-imagines everything above and around them for owner-standard global expedition service — from the tropics to the poles. In outline, the scope includes:
Grant Maughan's conversion study — the ice-class platform re-imagined as a global explorer yacht: owner and guest decks, a full-beam beach club, a certified helideck, and tender, submarine and toy handling over the working aft deck.




Conversion renderings — Grant Maughan Design. Indicative concept; final arrangement to owner specification.
The hull as she operates now — an ice-class construction and rescue AHTS with a heavy subsea crane and active helicopter operations.
