Hull innovations
From wave-slicing bows to monopile-ready sterns, we help you achieve more uptime, lower emissions, and greater comfort on board.
Innovations that power safer, greener and more efficient operations
At Ulstein, we see hull innovation as key to delivering safer, more efficient maritime operations. The X-BOW® enhances seakeeping by slicing through waves, improving both efficiency and comfort. The X-STERN® offers similar benefits at the aft, boosting operability when manoeuvring stern-first. For vessels requiring agility, the TWIN X-STERN® delivers optimised performance at both ends. The ULSTEIN U-STERN™, purpose-built for offshore wind operations, particularly monopile installations, features a unique shape that reduces resistance and fuel consumption while enabling safer, smarter handling of heavy components. Together, these designs empower you to operate with greater efficiency, sustainability, and confidence—even in the most demanding conditions.
X-BOW®
The ULSTEIN X-BOW, the inverted bow concept, redefined marine engineering. The bow concept was launched in 2005, together with the first shipbuilding contract, and gained immediate interest from shipowners. The X-BOW hull line design has been tried in most weather conditions.
X-STERN®
The X-STERN introduces the documented X-BOW® effect to the aft ship, harnessing the benefits of improved safety for crew and equipment, increased flexibility in operations and reduced fuel consumption.
TWIN X-STERN®
The TWIN X-STERN is the latest addition to the innovative designs of X-BOW and X-STERN that enhance fuel efficiency and operability.
