The latest expedition cruise vessel in Sunstone Ships’ Infinity series, Ocean Explorer, has been delivered by China’s CMHI Haimen shipyard. The vessel will be operated by Vantage Cruise Line.
Like other ships in the series, the Ocean Explorer is a customised version of Ulstein’s CX103 design, built to Polar Code Category B, with Polar Class 6 and Ice Class 1A on machinery. The ship will use low sulphur marine gas oil.
Greg Mortimer, the first vessel in the Infinity series, was commissioned in September 2019, and four more ships are scheduled for delivery, two in the balance of this year and two in 2022. All of the vessels have Ulstein’s distinctive X-Bow for improved seakeeping.
The ships have Tier III engines with SCR systems, heat recovery arrangements and LED lights. All have dynamic positioning, zero-speed stablisers and waste water management systems.
Lead naval architect, Torill Muren, commented on the ships’ design. “We have developed a vessel where the hull has been optimised for low fuel consumption with computational fluid dynamics analysis,” he said. “In addition, we have implemented the Ulstein X-Bow hull line design, a solution firstly introduced to the offshore segment and only recently to the cruise industry.
“In addition to the fuel savings, the X-Bow softens the movements in head seas, reducing slamming and vibrations and inceases the comfort and rest for passengers and crews.”
