What they say

  • “They performed an exploratory study on rules and regulations for several of our focus regions and a selection of our vessels and technologies. This gives us great insights on what is important for our customers. We now understand better what the impact of EU ETS will be for our clients, and which actions we should take in order to be prepared for the future.”

    Matthijs Richelle - Service Development Manager

  • “Sustainable Ships is a great initiative; everyone is fully dedicated to help the maritime sector decarbonize! The overall approach helps a larger company as Van Oord to differentiate in depth on the decarbonisation options provided in the overview. The background knowledge at Van Oord, on its turn, helps Sustainable Ships to further professionalize with respect to qualitative answering. It was really nice to cooperate with the Sustainable Ships’ team.”

    Martin de Geus - Team Lead Equipment Van Oord

  • “Sustainable Ships embarked us on a journey to uncover which sustainability measures would deliver the biggest bang for our buck. Through this process, we gained invaluable insights into the key factors driving the decarbonization of our fleet. It was an educational experience, helping us to make a strategy and on what to focus in the future. The journey went beyond the nitty-gritty technical details - like operational profiles or engine usage. We also focused on the cost-effectiveness of different decarbonization measures to make sure the measures make sense for our ships. Looking back, we are grateful for the guidance in navigating the complex landscape of sustainability..”
