Steel cut on first Ulstein Twin X-Stern design CSOV

The dual-fuel methanol MDO/HVO powered CSOV is being built to Ulstein Design & Solutions AS’ SX216 design. The two vessels are the first contracted to implement Ulstein’s TWIN X-STERN design. 

Ulstein Design notes that the design is particularly noteworthy because the vessel features two sterns and main propeller units at each end. The combination of thrusters and symmetrical hull design results in lower energy consumption and reduced motions, and therefore, higher operability and comfort. This concept dramatically improves the manoeuvrability and ability to stay in position, and could lower energy consumption in DP2 mode.

The first newbuild CSOV will enter Acta Marine’s fleet in the second quarter of 2024, with the second following three months later. 

The 89-metre long vessels will be equipped with an SMST-provided motion-compensated crane and a motion-compensated gangway for safe personnel transfer in significant wave heights up to 3.0 metres. The CSOV provides excellent accommodation facilities for up to 135 people. In addition to the Methanol MDO/HVO engines the vessels feature a battery power storage system creating further energy efficiency and CO2 reduction.
