Ocean Explorer, an Ulstein-designed expedition cruise vessel featuring the X-BOW®, was successfully delivered from the CMHI Haimen yard, China, on 13 July 2021.

Norway-based Ulstein has delivered several expedition cruise ship designs for the SunStone Ships’ INFINITY series, all for construction at the CMHI yard. Ocean Explorer will be operated by Vantage Cruise Line.

The first X-BOW vessel in the INFINITY series, Greg Mortimer, was delivered in September 2019.

When signing up for these vessels, SunStone Ships’ President/CEO Niels-Erik Lund commented that “We decided to partner up with Ulstein due to their hull and the technical design, as well as their site team in China to supervise the production”.

The construction has continued smoothly. There are two more vessels in the INFINITY series which are scheduled for delivery in 2021, and two for delivery in 2022.

“All the vessels in the INFINITY series have Tier III engines with SCR catalysts to reduce emissions. They run on low sulphur Marine Gas Oil (MGO), have heat recovery systems and LED lights. On top of this comes the waste-water treatment and management system that cleans the waste water before discharging it.”

The ships in the INFINITY series have Ulstein’s patented X-BOW design, zero-speed stabilizers and dynamic positioning, and are built to Polar Code Category B, with Polar Class 6 (Ice Class 1A on machinery). All vessels are customised versions of the ULSTEIN CX103 designs.
