MSMSC Opera is a cruise ship built in 2004 and currently operated by MSC Cruises. She served as the flagship of the company until MSC Musica entered service in 2006. She can accommodate 2,055 passengers in 856 cabins, and host a crew complement of approximately 740.
In May 2010, one week after a similar incident on board the MSC Orchestra, UKBA officers at Dover found a large quantity of cocaine concealed in four passenger cabins. Four Latvians and three Lithuanians were later convicted at Canterbury Crown Court and sentenced to a total of 84 years imprisonment.
On 14 May 2011, MSC Opera suffered engine failure in the Baltic Sea. She was towed to the port of Nynäshamn, south of Stockholm, where passengers were transferred to small boats. Around 1,700 passengers were flown home from Stockholm during the day. The ship was without power after the engine failure and internet reports stated that bathrooms were inoperable, causing some sanitation issues. Passengers were given a voucher to cover the cost of the cruise. On 17 May 2011, MSC Opera departed Nynäshamn en route to Gdynia in Poland for repairs.
