Today, Oceania Cruises announced that the debut of its new, 1,250-passenger Riviera (sister ship to 2011’s Marina) will be delayed by three weeks due to protests and strikes at Italian shipbuilder Fincantieri’s shipyard near Genoa.

The ship’s maiden voyage — a 10-day “Pearls of the Aegean” cruise that includes an overnight aboard ship in Venice before visiting Dubrovnik, Kotor, Corfu, Monemvasia, Crete, Santorini, Kusadasi, Delos, Mykonos, and Athens — will now take place on May 16 rather than April 24. Guests booked on affected sailings have the option of rebooking another cruise and receiving a future cruise credit of $250 to $1,000 per guest (depending on stateroom category) or taking a full refund.

“We regret that labor strikes have caused this delay,” said Fincantieri CEO Giuseppe Bono in a media statement. “All of us at Fincantieri are committed to producing a superior quality ship and we will deliver a truly magnificent vessel to Oceania Cruises without further delays.”

Labor disruptions at Fincantieri’s Sestri Ponente shipyard, led by metalworkers' union Federazione Impiegati Operai Metallurgivi (FIOM), have flared in opposition to a December agreement between state-owned Fincantieri and two other trade unions. That agreement included plans for temporary layoffs and a gradual reduction of the workforce. In response, workers at Sestri Ponente have mounted strikes, occupied Genoa’s airport, and taken their protests into the city’s streets. Workers at the company’s facility in Palermo, Sicily, which handles ship repairs and conversions, have also mounted strikes and protests.
