The two 200,000gt World class ships are scheduled for delivery in 2022 and 2024, respectively, and will be the first MSC Cruises cruise ships configured to use LNG as a marine fuel.
They will each be fitted out with one BIO-SEA B02-0300 skid-mounted unit capable of treating ballast water flows of 300m3/h. The BIO-SEA skids will also feature an embedded power management cabinet for ease of operation.
Similar units will be supplied for installation in two new Meraviglia class vessels, of which the most recent, MSC Bellissima, has just been delivered. In total, four Meraviglia-class cruise ships will operate the BIO-SEA system.
Largest ship in the MSC Cruises' fleet
Benoît Gillmann, BIO-UV Group’s President and CEO, said: ‘The order follows the success of the installation and operation of similar units aboard MSC’s Meraviglia-class of cruise ships. When the first World class vessel enters service in 2022, it will be the largest cruise ship in the MSC fleet.’
Another cruise ship owner to install BIO-SEA technology is RCCL-brand, Celebrity Cruises. A 250m3/h flow rate capacity unit has been selected for an additional three Edge-class vessels, also being built at Chantiers de l’Atlantique. One unit is already in-service aboard Celebrity Edge.
Xavier Deval, BIO-UV Group’s BIO-SEA Business Director, said: ‘BIO-SEA’s short holding time at full flow is of primary importance for cruise ships as they visit a new port every day and consequently carry out ballasting/deballasting operations frequently.’
