What is XCF?

XCF, short for X-shaped Concrete Floater, is Mareal’s innovative semi-submersible platform designed to deliver a robust and efficient solution for floating offshore wind. It blends hydrodynamic performance with industrial feasibility, making it a balanced and scalable option for large wind farm developments.

The platform’s semi-submersible configuration enhances seakeeping, reduces turbine motions, and limits mooring system sizing. Its unique X-shape enables an efficient post-tensioning strategy, increasing structural durability and cost-effectiveness. XCF is engineered to perform in demanding marine environments while being manufactured locally with minimal exposure to global supply chain risks.

At Mareal, we focus on integrating proven technologies and components to lower development risk and ensure project reliability.
