Costa Atlantica First To Earn RINA's Green Star
Italian classification society RINA has launched Green Star, which it is dubbing the new environmental standard for shipping. The recently delivered Costa Atlantic from Kvaerner Masa-Yards for Costa Crociere is the first ship to meet the green standard, earning both the Clean Sea and Clean air voluntary nota- tions from RINA.
The Clean Sea notation means that bunker tanks must be installed over double bottoms to prevent accidental discharge of oil in a low-speed accident.
Ships must also be fitted with holding tanks for all black and gray water waste, and must meet the standards set down in the voluntary IMO Marpol Annex IV. Special requirements ensure garbage is disposed of safely, and ships must not use TBT-based anti-foulings.
The Clean Air notation sets limits on SOx and NOx emissions from the engines, and requires compliance with the voluntary standards of Annex VI to Marpol. There is a three percent limit on sulfur content in fuel that can be burnt, and RINA also sets requirements for refrigeration gases and their containment in the case of an accident.
Carnival Corp., the world's largest cruise line, has applied for the Green Star logo for three sisterships currently under construction at KMY.
