Emissions and energy efficiency of ship machinery
Cut costs. Boost efficiency. Stay compliant.
As a shipowner or ship manager, you face increasing pressure to reduce fuel costs, enhance energy efficiency, and comply with tightening emissions regulations. Choosing the right machinery and system upgrades is critical - but complex. The wrong decisions can lead to higher operational costs, compliance risks, and reduced vessel performance.
Key challenges:
- Maximizing ROI: Which machinery investments deliver the best fuel savings and long-term value?
- Adopting new technologies: How do alternative fuels and new technologies impact efficiency and fleet performance?
- Optimizing across operations: How can you ensure your machinery performs efficiently across varying operating conditions?
With expert guidance, you can turn these challenges into opportunities for profitability, sustainability, and long-term success.
Smarter machinery and energy efficiency decisions
DNV Maritime Advisory helps shipowners and managers make profitable, data-driven decisions when it comes to both newbuilds and retrofits. Our expert evaluations ensure your machinery and systems are:
- Future-ready – Compliant with evolving emissions regulations
- Cost-effective – Optimized for lower fuel consumption and lifecycle costs
- Performance-driven – Tailored to your vessel’s specific operational profile
Maximizing efficiency across your fleet
We assess and compare machinery systems and energy-saving technologies, providing actionable insights on:
- System-level machinery optimization: Ensuring the best configuration for fuel efficiency and performance.
- Alternative fuels and Carbon Capture: Evaluating ammonia, hydrogen, methanol, LNG and BOG management, hybrid options, and onboard carbon capture for emissions reduction – often combined with our Fuel Selector service for a comprehensive evaluation.
- Efficiency-boosting technologies: Exploring waste heat recovery, fuel cells, shaft generators, propeller optimization, and more – often integrated with our Decarbonization service for a holistic approach.
- Operational and financial impact: Optimizing energy management in sailing, cargo and port operations; improving energy consuming operations with daily operation advice for cargo heating and discharge for tankers, and fuel management for LNG-fuelled ships; quantifying fuel savings, maintenance costs, and regulatory compliance.
- Performance metrics and compliance: AER, CII, EEDI/EEXI calculations for emissions reduction strategies.
