Emission Control Zones Are Reshaping Marine Operations.


Maritime operators face increasingly strict environmental regulations that make diesel propulsion and auxiliary power economically unviable.
Design and specifications subject to change. The final VapourGen units are optimised for real world deployment; actual product appearance may vary slightly based on final engineering certifications and site-specific operational needs.
The Ocean Used to Be Unregulated. It Isn't Anymore.

EMISSION CONTROL ZONE RESTRICTIONS
EMISSION CONTROL ZONE RESTRICTIONS
IMO and national regulations tightening:
• IMO 2020 sulfur cap (0.5% vs 3.5% previously)
• Emission Control Areas requiring <0.1% sulfur
• Carbon Intensity Indicator (CII) ratings affecting vessel value
• Port State Control penalties for non-compliance
• Coastal nation ECZs expanding (India included)
Remote towers rely on diesel backup with continuous operational challenges:
• Fuel theft averaging 15-25% of consumption
• Logistics costs for delivery to remote sites
• Noise restrictions in urban and residential areas
• Rising diesel costs (+40% since 2020)
• ESG mandates requiring emission reductions

OFFSHORE & ISLAND OPERATIONS
OFFSHORE & ISLAND OPERATIONS
Remote operations face unique constraints:
• Offshore platforms beyond grid connection
• Island port facilities requiring diesel import
