DNV GL releases new Tier III compliance guide

Ship operators should consider carefully the various technologies for compliance, the classification society recommends, and depending on a vessel’s likely operating profile, the best compliance option will depend on a variety of factors. These are likely to include trading pattern, engine size and speed.
The guide examines various compliance options including selective catalytic reduction, exhaust gas recirculation, alternative fuels, engine modifications, direct water injection, fuel-water emulsion, and intake air humidification.
NOx Tier III compliance technology need not simply be a matter of cost, DNV GL says. Other benefits include demonstrating a company’s commitment to ensuring sustainable operations, as well as direct financial benefits at ports which offer discounts for vessels complying with third-party environmental schemes such as the Environmental Ship Index – ESI.
