Sustainability

Let’s Ensure the Wind Blows in the Right Direction: Toward a Sustainable Future.

At O.S. Energy, we know that wind is only the beginning. Our mission is to transform offshore wind’s entire supply chain, bringing it on course towards climate neutrality. We have been constantly modernising our fleet (one ship per year on average) and have been researching innovative ways to cut emissions, while maintaining safe and efficient offshore services.

Our newest vessels particularly reflect this commitment towards sustainability: They will be able to run on methanol and other fuels, allowing us to turn the latest scientific progress into actionable technology. While future maritime fuels may involve diverse solutions across industries, O.S. Energy is actively exploring its own methods. Our goal is to be among the first to operate emission-free ships in the offshore industry.
