Review of Ocean Explorer

The 2021-built MS Ocean Explorer cruise ship is an ice-strengthened (polar class 1A / PC6) expedition vessel owned by SunStone Ships (USA) and operated under charter by Vantage Cruise Line - subsidiary and brand owned by Vantage Travel Service Inc (brand name "Vantage Deluxe World Travel").

Ship technology

Ocean Explorer is the third in a series of ten "Ulstein CX103" design (Infinity-Class) expedition vessels, with sisterships Greg Mortimer (2019-Aug), Ocean Victory (2021-March), Sylvia Earle (2021-Sept), Ocean Odyssey (2022-Feb), Ocean Discoverer (2023-March), Ocean Albatros (2022-Oct) plus 4 more (TBN) units. The patented ULSTEIN X-BOW design is one of the unusual for expedition ships 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.

With the highest for passenger vessel ice-class 1A (Polar Class 6 / PC6), MS Ocean Explorer 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.

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 maritime industry's latest propulsion and return-to-port systems, as well as dynamic positioning technology. These computer-controlled systems allow automatic maintenance of the ship's position via propulsion units (thrusters and propellers). This allows stable floating while maintaining the necessary stability for launching watercraft - and without using anchors.

Shipboard facilities

The newbuild expedition vessel features dedicated outdoor observation areas (including fore-located Observation Deck with two Hydraulic Platforms and two Viewing Platforms), stern marina (watersports platform serving company's sea kayaking, snorkeling and scuba diving programs), a fleet of 20x Zodiacs (large-capacity motorized boats used for passenger transportation - tendering and landings). The aft-located Zodiac loading platform is a new design and allows easier and faster boarding. Sun Deck (top-deck forward) is furnished with premium garden furniture (sofas, armchairs, sun loungers) and is used for both relaxation and wildlife viewing. At top-deck's bow is the Observation Lounge (served by its own Bar), midship is the funnel (with four stacks/engine exhaust pipes).

Other facilities include Medical Centre (Infirmary), Change Room (Mudroom), Bar Lounge (lecture theater forward on Deck 5), Dining Room Restaurant, Ship Shop, Lobby area (Reception Desk), Library, Art Room, Wellness Centre (Fitness, Spa, Sauna Room, Treatment Rooms for Massages), Lower Sun Deck (Deck 7 aft, with lifeboats and liferafts), Upper Sun Deck (Deck 8 midship, with sunbathing area and two whirlpool hot tubs).

Four Zodiac Docks (2 on each side, hull access at sea level) serve as boat launching platforms.

Decks and Cabins

Ocean Explorer staterooms (a total of 80) allow max passenger capacity 140.

    SunStone's shipbuilding contract with CMIH for Ocean Explorer (4th) and Ocean Discoverer (5th) Infinity-class cruise ships was signed on November 13, 2018, by Frank Zheng (CMIH's Vice General Manager) and Lars Stale Skoge (Ulstein's Commercial Director). On February 27, 2019, the Ocean Explorer ship-charterer (Vantage Cruise Line) announced planned cruises in East Asia and Europe (Mediterranean and Baltic-Scandinavia).

    The ship-chartering agreement includes a deal with the Miami-based company CMI Leisure Management. Ship management services include 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.

    Vessel's construction officially started on September 19, 2019, with the steel-cutting ceremony (hull/yard number CMIH 196-4) held at CMIH's Haimen Shipyard. The event was attended by several hundred VIP guests. The keel-laying ceremony was held on December 19, 2019. Vessel's launch (float out from drydock) was on August 12, 2020.

    Ocean Explorer ship's delivery was originally scheduled for January 2021, and the inaugural cruise for March 2021. However, the delivery to Vantage Travel was officially held on July 13, 2021, at CMIH's Haimen Shipyard. The boat then departed China for Manila Philippines (to be crewed), then continued to Valletta Malta (to get hotel staff and supplies) and to homeport Poole (England UK) for the inaugural season (starting late-August).

    On March 16, 2017, SunStone Ships Inc signed the shipbuilding agreement with the Hong Kong-based company "China Merchants Industry Holdings" (abbrev CMIH) for construction of 4 expedition vessels. SunStone is the world's largest (by tonnage) shipowner chartering exclusively expedition vessels to cruise travel companies. Since there is an option for an additional 6 sisterships, by this "ULSTEIN CX103" project could be built up to 10 units. The USD 260 million shipbuilding order for the 4 units was signed in June 2017.

    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 shipbuilding 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 seas). 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.

    Project's shipbuilder is CMIH's subsidiary "China Merchants Heavy Industry" (abbrev CMHI, shipyard near Shanghai).

    The ship 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 Wartsila-NOR (exhaust gas cleaning system, NOx gas reducing technology). The contract with Wartsila was signed in November 2017.


    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 maneuvering 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).

    Vantage Cruise Lines opened bookings on Ocean Explorer's inaugural cruises (11 itineraries) on May 30, 2019.

    Yellow Sea trials (in East China Sea) started on January 22, 2021, and were successfully completed on January 27. During the 5-day sea trials, the boat's machinery was tested by 150+ personnel, including crew, shipyard technicians, CMIH managers, Bureau Veritas representatives, SunStone Ships marine advisors.

    The vessel (IMO 9883194) is Bahamas-flagged (MMSI number 311000869) and registered in Nassau.
