Greg Mortimer Review

Review of Greg Mortimer

MS Greg Mortimer cruise ship is an ice-strengthened (polar class 1A / PC6) expedition vessel. The boat is owned by the Danish company SunStone Maritime Group (via its USA-based subsidiary SunStone Ships Inc) and is currently operated under charter by Aurora Expeditions (fleet/1991-founded Australian company specializing in Arctic and Antarctic cruisetours).

The vessel (IMO number 9834648) is currently Bahamas-flagged (MMSI 311000866) and registered in Nassau.

History - construction and ownership

Greg Mortimer is the first in a series of ten "Ulstein CX103" design (Infinity-class) expedition vessels, with sisterships Ocean Victory (2021-March), Ocean Explorer (2021-Feb), Sylvia Earle (2022-October, fleetmate), Ocean Odyssey (2022-March), Ocean Albatros (2022-Oct), Ocean Discoverer (2025-August). Four more units were intended but eventually canceled and replaced by the new BOUNDLESS Class boats.

The patented ULSTEIN X-BOW design is one of the unusual for expedition ship features. The vessel also utilizes the latest technologies in naval engineering. The ship is technically managed by Cruise Management International (Miami-based passenger vessel/fleet management company). CMI Leisure Miami handles hotel operations.

For the interior designs of this entire series of SunStone-owned ships was contracted the Weston Florida-based company Tomas Tillberg Design.

Aurora Expeditions cooperated with the US-based shipowner SunStone Ships Inc to construct a custom-designed vessel for expedition-type voyages in the polar regions, providing the industry's best adventure travel vacation experiences and modern amenities.

Greg Mortimer cruise ship

Aurora Expeditions is among the pioneers of polar expedition cruising and a leading adventure travel company on the Australian market. The company was one of the first to introduce ship travel to numerous remote destinations in the polar regions. Established in 1991, in 2008 Aurora Expeditions was sold and the new owners remained true to the original expedition spirit. Initially offering small-group cruises to Antarctica, Aurora Expeditions now also operates expedition voyages to Norway's Svalbard Islands, Russia's Far East, Greenland, Papua New Guinea, Africa (Chobe River safari cruises in Botswana), Amazon River.

Ship technology

The major advantage of the patented "ULSTEIN X-BOW" design is the ship's ability to navigate with improved stability in comparison to traditional bow-design vessels. X-BOW vessels are less subject to vertical motions (induced by waves), continuing on course smoothly while maintaining high speeds. The ship's engines use less fuel, which results in reduced air emissions and fuel consumption.

The ship is equipped with the latest propulsion and return-to-port systems. It also has top-notch dynamic positioning technology - computer-controlled systems allowing automatic maintenance of the vessel's position through its own propulsion units (thrusters and propellers). This allows stable floating while maintaining the necessary stability for launching watercraft - and without using anchors.

With the highest for passenger vessel ice-class 1A (Polar Class 6 / PC6), MS Greg Mortimer has icebreaking capacity 1 m (3 ft) and complies with the maritime industry's latest polar code requirements and specifications. The boat offers unprecedented levels of safety and environmental protection. Exclusively designed for polar cruises, the ship allows Aurora Expeditions to continue to provide the company's authentic, top-quality small-ship travel experience.

Greg Mortimer Wiki

Ship's name honours Greg Mortimer (born 1952) - Aurora Expeditions company's co-founder (together with his wife Margaret Mortimer). He is best known as one of the first Australians to climb Mt Everest without oxygen (in October 1984).

On March 16, 2018, officially started vessel's construction with the steel-cutting ceremony at Jiangsu FRP shipyard (Haimen Base, China). The ceremony was attended by Xianfu Hu (CMIH's General Manager) and Niels-Erik Lund (SunStone's CEO). On June 12, 2018, was held vessel's keel-laying ceremony. The ship was launched (floated-out from drydock) on March 12, 2019. The launching ceremony was attended by Mr Greg Mortimer (Aurora Expeditions), Mr Xianpu Hu (China Merchants Group's Managing Director) and Mr Niels Erik Lund (SunStone Ships' President).

With a combined delivery and naming ceremony, the vessel was christened on September 6, 2019 (at the Haimen Shipyard) but the official naming ceremony was held on October 31 in Ushuaia Argentina. The ceremony was led by godmother Margaret Mortimer (co-founder of Aurora Expeditions) and attended by officials from the shipowner (SunStone Ships Inc), CMI Leisure Management, Ulstein Group, VIP guests, as well as the cruise ship's crew and passengers on the current voyage.

Following the delivery, the vessel's MMSI number (flag-state) was changed from 205077000 (Belgium) to 311000866 (Bahamas).

Greg Mortimer cruise ship

At the end of February 2018, the ship-charterer Aurora Expeditions announced the company's deal with "CMI Leisure Management" (Miami-based company). The MS Greg Mortimer ship management deal included staffing, hotel services, housekeeping, onboard food and beverages, purchasing supplies, logistics. CMI Leisure is among the world's leading companies providing small-ship management services. The company was first contracted by Aurora Expeditions for managing the SunStone-owned ship MS Polar Pioneer.

On March 16, 2017, SunStone Ships Inc signed the 4-shipbuilding agreement with the Hong Kong-based company "China Merchants Industry Holdings" (abbrev CMIH) for the construction of the 4 units. SunStone is the world's largest (by tonnage) shipowner chartering exclusively expedition vessels to the cruise travel industry. , Since there is an option for an additional 6 units, by this so-called "ULSTEIN CX103" project could be built up to 10 vessels.

The company CMIH is a subsidiary of China Merchants Group (among the country's largest groups of companies). Following the contract with SunStone Ships, CMIH signed an agreement with the Norwegian company Ulstein Design (part of Ulstein Group, headquartered in Ulsteinvik Norway) to supply the ship design and equipment package (ULSTEIN COM / Navigation Bridge system, and the integrated automation systems ULSTEIN IAS and ULSTEIN POWER), and also to supervise the shipyard works. For the ship's hotel design was contracted the Florida (USA)-based company Tomas Tillberg Design International (specializing in passenger vessel design). The design features Ulstein's patented X-BOW (providing fuel efficiency and significantly improved stability in rough weather). The vessel complies with the 2009-issued SOLAS requirements for "Virtual Anchorage" and "Safe Return to Port" (SRtP) implemented via Dynamic Positioning System (computer-controlled, automatically maintains ship's position) and Zero Speed Stabilizers (roll reduction system).

CMIH also signed an agreement with the Finnish company "IS Makinen Inc" to pre-fabricate the vessels' cabins, wet units and interior public spaces. For this purpose, Makinen established a cabin assembly plant and an interior workshop facility at the shipbuilding yard in China.

The project's shipbuilder is the subsidiary company "China Merchants Heavy Industry".

The vessel (Jiangsu yard/hull number CMHI-196-1) is powered by 4x "Wartsila 20" diesel engines (two 6-cylinder plus two 8-cylinder) running on HFO (heavy fuel oil). The 6-cylinder engines are fitted with the exhaust gas cleaning system "Wartsila NOR" (NOx gas reducing technology). The contract with Wartsila was signed in November 2017. The engines were delivered in January 2018.

Vessel's propulsion system is diesel-electric (twin-screw) and designed by Brunvoll Volda AS (Volda Norway-based company specializing in marine propulsion, positioning and manoeuvring systems). For the ULSTEIN CX103 project, Brunvoll contracted DMC (Damen Marine Components, Hardinxveld Giessendam Holland-based marine equipment manufacturer) to produce and supply the vessel's two rudders (model Van der Velden ATLANTIC) and two steering gear systems (model Van der Velden COMMANDER).


The USD 260 million shipbuilding order for the 4 boats was signed in June 2017. The first vessel of the series (Greg Mortimer) was scheduled for delivery in August 2019, followed by one ship every 6 months after.
