Carnival Cruise Line

The vessel was originally intended to be constructed in Japan, after Carnival's most recent acquired ship the TSS Festivale had received a major refit there.^[8] However, the construction ended up being awarded to the Danish shipyard Aalborg Vaerft. The Tropicale was launched in 1981, and was the first cruise ship custom-built for the company, introducing Carnival's characteristic winged funnel, designed by Joe Farcus.^[9][8] The interiors were also designed by Joe Farcus, evolving Carnival's signature themed lounges.^[8]

As the company expanded and acquired larger ships, Carnival decided that Tropicale would be their 'test ship' for new cruise destinations, and as such was the first Carnival ship to be based in San Juan, New Orleans, Alaska, and Tampa. In 1985 the vessel appeared in an episode of the A-Team called "Judgement Day (part 2)".^[10] The ship also appeared in a season four episode of Growing Pains.

On September 19, 1999, the vessel's engine room caught fire en route from Cozumel to Tampa.^[11] While disabled in the Gulf of Mexico, the ship was nearly struck by Tropical Storm Harvey.^[12] Luckily one of the engines was restarted and the ship was able to get out of the way of the storm before it hit. No crew or guests were injured during the two days the Tropicale spent without propulsion. The vessel was slated to replace the SS Dolphin IV of Cape Canaveral Cruise Line in 2001, but before Carnival Tropicale could enter service, the vessel was transferred to Carnival Corporations division of Costa Cruises, where she was renamed Costa Tropicale.

Costa Cruises & P&O Australia

The vessel underwent refits in Genoa over the course of 2001 and 2002, removing the iconic winged funnel, and replacing with the traditional Costa upright yellow funnel design.^[13][14] The interiors were completing renovated, transforming the Carnival themed lounges into the contemporary Italian style seemed on other Costa ships.^[15] Costa Tropicale served with the company until 2005, when replacement by larger, more modern cruise ships prompted a transfer to another Carnival Corporation division: P&O Cruises Australia, where the vessel again underwent a major refit in Palermo, Italy and was renamed Pacific Star. She was formerly Queensland's latest cruise liner, based in Brisbane, performing cruises along the Tropical Queensland coast, to various islands in the South Pacific, New Caledonia, and to New Zealand.

Pullmantur Cruises

In 2008 the Pacific Star was sold to Pullmantur Cruises and renamed Ocean Dream following a refit in Singapore. In June 2009, an outbreak of swine flu occurred about the Ocean Dream during a cruise around Central and South America. The ship docked in Margarita, Venezuela to allow its Venezuelan passengers to disembark, before heading to Aruba, where the remaining passengers were able to leave the ship. An earlier report had suggested that the ship had been placed in quarantine, however, the ship's owners Pullmantur later denied that this was the case.^[16]

Peace Boat

In 2012 the M/S Ocean Dream , left the Pullmantur Cruises fleet, and was chartered to Peace Boat, replacing the SS Oceanic.^[17]

In September 2020 Cruise Capital informed according to Hong Kong Cruise Society, Peace Boat is to replace the contracts of two ships Ocean Dream and Zenith from service, replacing them with one larger ship, chartered and renamed Pacific World from Spring 2021. Specifications released by Peace Boat suggested the new ship is the current Sun Princess, which is the only vessel to have done such deployments.^[18] Later this month, Carnival announced that they have sold the Sun Princess.^[19]

The Ocean Dream was sold for scrap and beached in Alang, India, on 1 January 2021. On March 27, 2021, the scrapping process started on her.^[20]
