During an afternoon dedicated to sustainability and climate action at IMPA Hamburg 2025, we are delighted to introduce our second afternoon presentation:

Energy-Efficient Purchase Decisions Using a New Maritime ISO Standard

Thursday, 10 April, 14:30 - 14:55

Are you making the right purchasing decisions when it comes to energy efficiency? With the launch of the new ISO 8933 standard, shipowners and operators now have a clear framework to measure, compare, and optimise the efficiency of onboard systems.

Join us for an engaging session on how standardised energy efficiency assessments can help maritime purchasers make smarter decisions, reduce fuel costs, and improve operational performance. We’ll showcase real-world examples of how applying ISO 8933 can deliver measurable savings and ROI while ensuring transparent and data-driven equipment selection.

Key Takeaways

• How the ISO 8933 standard enables objective efficiency comparisons
• Financial impact: Understanding energy savings and ROI for onboard systems
• Smart procurement: Making data-driven purchasing decisions for optimal efficiency

Set to offer actionable takeaways for maritime procurement professionals, this afternoon session from IMPA SAVE Council Member Rasmus is not one you will want to miss.
