Simeon Tienpont
CEO De Goede Ree
“ The collaboration with our team and clients reminds me of the composition of the multidisciplinary design team that I had available to me as an engineer and in my career as a professional sailor in the America’s Cup, the oldest and perhaps most prestigious sporting event in the world. The decisive part in the design of the winning boat lay in its operating systems , more than in the hull shape itself. The role of the marine engineer has increasingly shifted to a technical maritime integrator, where operating systems on board must be able to communicate with each other and act under the guidance of the crew.
The boat talked to us and we, as the crew, talked back.
In the maritime industry, including onboard commercial ships, I still see a lot of room for improved efficiency and cost savings with this approach. This is exactly where RED-TO-GREEN (R2G) maritime engineering services will aim to contribute to an efficient, sustainable and green maritime sector. “
