Maritime Sisters

We are the Maritime Sisters and we are on a mission to propel the transition to a sustainable maritime future. We challenge the status quo – in every way. Not as a goal in itself, but for a futureproof (maritime) world.

 Full of energy we are relentlessly committed to accelerating the initiatives, collaborations and innovations that are needed to transform the maritime industry from a mostly analogue and fossil, to a fully digital and sustainable sector. The good news: as ports in essence are places where worlds come together, they provide the perfect breeding ground for innovation. This is why we chose this to be our ‘’workplace’ from which we try to contribute to making the change happen.

We are very much looking forward to moderating the roundtable ‘Future Challenges’ and – together with the impressive line-up – turning these challenges into opportunities!
