A New Benchmark in Luxury

At a grand ceremony at its headquarters in Genoa, Italy, Costa Cruises christened its new flagship vessel as Costa Diadema on November 7, 2014. Diadema means tiara or an ornamental, jeweled band. It is the largest cruise ship to hoist the Italian flag and began its inaugural voyage on November 8.

Studded with a stunning Samsara Spa, seven restaurants, breathtaking ambience, fifteen bars, and engaging entertainment avenues, the Costa Diadema is truly a jeweled ornament. Everything about the ship is king sized. Even its nickname ‘Regina del Mediterraneo’ or ‘Queen of the Mediterranean’ radiates regality.

Costa Diadema is largely based on the design of Carnival Cruise Lines’ Carnival Dream. Fincantieri built this new flagship at its Marghera Shipyard, Venice. This is the largest vessel ever built at this yard. Joe Farcus designed the interiors. The cruise ship will carry the RINA Green Star Notification, something all Costa Cruises’ vessels do.
Carnival Corporation & PLC. is the parent company of a host of cruise companies viz. Costa Cruises in Southern Europe; Carnival Cruise Lines, Princes Cruises, Holland America Line, and Seabourn in Northern America; P&O Cruises (Australia) in Australia; AIDA Cruises in Germany; and Cunard and P&O Cruises (UK) in the United Kingdom.

Costa Cruises has invested $701 million in Costa Diadema and nearly $6.3 billion in ten new vessels, all built by Fincantieri since 2000. Costa Cruises’ shipbuilding at Italian shipyards created 12,300 jobs throughout the supply chain and the tourism segment in Italy. In 2010, these operations contributed about $2.8 billion to the Italian economy.

Technical Details
Samsara Spa is the chief attraction. Spread over four floors across a sprawling 7,800m2 area, it hosts a spa, a Turkish bath, a gym, a sauna, a steam bath, a solarium, and a thalasso-therapy pool.

  • Because her builders laid keel before the Safe Return to Port Requirements took effect, the Costa Diadema complies only partially with these provisions. Primary modifications / additions to the Carnival Dream design include:
  • Emergency Diesel Generator (EDG): serving the passenger comfort switchboard is the capital modification. The vessel also has an EDG for the Solas switchboard. The additional EDG is takes over in case the Solas-EDG fails. This is of course a response to the power failure fiasco aboard Carnival Triumph in February 2013
    Scrubber / Carnival’s ECO Exhaust Gas Cleaning (ECO-EGC): removes toxic contaminants from exhaust gases and makes the Costa Diadema compliant with Emission Control Area (ECA) regulations limiting sulphur content in ship fuel to 0.1%

The ECA cap comes into force from January 1, 2015. This is the first time an Italian shipyard has installed such equipment
