Turning visions into reality
In the vast expanse of offshore wind energy, cable-laying vessels are essential—the silent architects of our renewable future. As wind farms grow larger and more ambitious, the demand for efficient cable installations has intensified. Introducing the ULSTEIN SX225, a vessel designed to tackle the challenges head-on.
Charting a greener course
The world’s need for clean electricity is more pressing than ever as we face the challenges of climate change and the transition towards renewable energy sources. The ULSTEIN SX225 is designed to be a significant player in this transition. It's a large platform with increased operability that serves a dual purpose.
The SX225's capabilities in supporting the offshore wind industry and its contribution to power global connectivity underscore its role as an embodiment of a commitment to a greener future.
- A design tailored for tomorrow:
- The ULSTEIN SX225 stands at the forefront of innovation. With a staggering cable capacity of 20,000 tonnes, it can handle the largest wind farms with a single load. This vessel isn’t just about size but efficiency, precision, and adaptability.
- Dual carousels - a symphony of storage:
- The vessel’s cable storage system is ingeniously divided into two carousels. An 11,000-tonne carousel efficiently manages cables on deck, while an additional 9,000 tonnes are stored below deck. This dual-carousel setup ensures seamless cable handling during installations.
- ULSTEN TWIN X-STERN - navigating the elements:
- The ULSTEIN SX225 features the groundbreaking ULSTEN TWIN X-STERN design. Six azimuth units—three forward and three aft—provide exceptional dynamic positioning (DP) capability. The TWIN X-STERN platform is also a prerequisite for operating in shallow waters on high DP capability. Imagine a vessel that dances with the waves, maintaining stability even in challenging conditions.
- ULSTEIN SX225 - a vessel for global energy connectivity:
- The ULSTEIN SX225, renowned for its efficient wind farm-to-shore connections, serves a dual purpose. It facilitates power transmission from wind turbines to land and is vital in laying intercontinental power cables, reinforcing global energy networks and fostering a greener future.
- Net Zero Ready - pioneering sustainability:
- The ULSTEIN SX225 is not just mere functionality. It is Net Zero Ready, prepared for dual fuel operation with methanol. The vessel has two battery rooms, each initially equipped with 1,100 kWh of battery capacity—spinning reserves and peak shaving in action.
