Costa Diadema

The 2014-built Costa Diadema cruise ship is of the Dream-class Costa liners, the flagship (replacing Costa Fascinosa) and the newest of Costa Cruises vessels. Diadema means “tiara” in Italian.

The vessel (IMO number 9636888) is currently Italy-flagged (MMSI 247353700) and registered in Genoa.

History - construction and ownership

Costa Cruises is a Genoa-headquartered subsidiary company owned by Carnival Corporation. Costa is Europe's second-largest cruise line (after MSC) with year-round operations in the Mediterranean. Costa was founded in 1854 as a cargo shipping company. It started passenger shipping services in 1947, with regular Transatlantic crossings between Europe (Italy) and South America. In 2000, Costa Cruises was acquired by Carnival Corporation (shipowner).

The 3800-passenger ship Costa Diadema is designed with many innovations in different areas such as food, entertainment, and technology. When put in service, Costa Diadema became the largest Italian-flagged cruise ship afloat. The shape of the cruise ship is similar to the Carnival's Dream, but is different in several ways: it is larger, with more space on board, with new decor and overall design. Diadema’s refined elegance and exquisite atmosphere will make you feel in comfort and full relax. A wide range of attractions awaits for you to experience endless food selection with flavors from the whole world, and the pampering Samsara Spa for maximum well­being.

Besides the ship's staff and crew, Costa cruise passengers are also served by Peper robots - the latest cyborg technology implemented fleetwide in 2016. These humanoid robots greet and guide passengers upon embarkation. They also assist them throughout the cruise by providing information and tips on onboard dining, entertainment, enrichment program (workshops, pre-scheduled events), casino and shopping promotions, shore excursions and tours. Pepper robots are mobile and communicate in 3 languages (English, German, Italian). They can also interpret human emotions by analyzing voice tones and facial expressions.

Itineraries

Costa Diadema itinerary program is based on European voyages (mainly in the Western Mediterranean). Seasonally, Diadema is deployed in the Caribbean for roundtrips from Guadeloupe (Pointe-a-Pitre on Grande-Terre Island) as well as Transatlantic crossings (RepositionCruises.com) between Europe and the Caribbean.

In September 2022 was canceled Costa Diadema's winter schedule (Nov 18, 2022, thru March 28, 2023/137x total departures) that included 14-day Canary Islands voyages leaving roundtrip from homeports in Italy (Savona), Spain (Valencia, Barcelona) and France (Marseilles). The boat restarted operations on April 7, 2023, out of Barcelona.

Diadema is among Costa's largest liners. Following the inaugural cruise/maiden voyage (November 10, 2014, Venice to Savona), it became the largest Italy-flagged vessel. and replaced Costa Fascinosa as flagship. From the same Dream-class (sisterships) are the "Carnival Fun Ships" Carnival Breeze, Carnival Dream, Carnival Magic. At the time, Diadema was Costa Crociere's largest shipbuilding order - placed on August 3, 2011. Vessel's construction (in Venice Italy at Marghera Shipyard) started on December 10, 2012 (keel-laying ceremony). The vessel was launched (floated out from drydock) on November 16, 2013, officially delivered to Costa on October 25, 2014, and christened on November 7 in Venice.

Diadema was the first-ever cruise ship to debut a laser maze show. All guests of the event were allowed to race through it. In 2016, on the liner was tested Costa's 4GOODFOOD program for decreasing food waste on cruises. The results were ~50% reduction in food waste, and up to 20% lower food consumption at the onboard self-service buffet restaurants.

In 2017, the Diadema became fleet's first vessel on which was introduced the onboard-made, certified mozzarella produced from buffalo milk. The new product (branded "Latteria del Curatino") was created via a partnership with two Campania-based dairy companies - "Comat" (dairy equipment manufacturer) and "Podere dei Leoni" (creamery, leading Italian producer of certified buffalo mozzarella). With Diadema, Costa became the world's first cruise company serving fresh-made mozzarella on board.
