Typically CLEAN and CLEAN DESIGN cover
CLEAN - Marpol Compliance with limited number of
additional requirements
CLEAN DESIGN - As for CLEAN, but with additional
requirements, including design requirements for
avoiding and limiting consequence of accidents

CLEAN and CLEAN DESIGN

• Covers 3 main areas of
• environmental concern
• Air, operational emissions
• Sea, operational discharges
• Defensive Design, accident prevention and
  consequence limitation (Clean Design only)
