Explore Circularity across the Vessel Lifecycle

Circularity: relevance, necessity and commercial opportunities for

Circularity in shipbuilding looks at the full lifecycle of a vessel – from design and construction to operation, maintenance and eventual dismantling. The goal is to use materials and resources in a smarter and more efficient way. This raises key questions: how can we reduce the amount of material we use? How can we make better use of the materials already in place? And how can we lower our dependence on limited resources? Applying circular principles helps reduce environmental impact, while also strengthening the industry’s long-term strategic position. By designing for circularity, the maritime sector can lower costs, increase operational efficiency, and support a more sustainable future. This session will be led by Sylvia and Marjolein Boer, also known as the Maritime Sisters, who bring their expertise and vision on circular innovation in the maritime sector.

Cable reduction and lower maintenance costs through smart engineering

One striking example of circular innovation comes from Alewijnse, a leading electrical system integrator. Together with supply chain partners – including the Maritime Sisters – Alewijnse is exploring how to significantly reduce the length of cabling installed on board vessels. The current use of cables is vast enough to circle the globe 1.5 times annually. Cutting cable use means lower material costs, reduced vessel weight, and a smaller environmental footprint, especially given the copper content. This session will highlight how targeted cable reduction strategies can deliver material savings, improve vessel efficiency, and support more sustainable shipbuilding practices.

From newbuild to decommissioning: circularity in TSHDs

What does circularity look like across the full lifecycle of a trailing suction hopper dredger (TSHD) – from newbuild to end-of-life? Van Oord is exploring this question by looking at both CAPEX and OPEX considerations, including the impact of lifetime extension strategies. With a focus on setting the right priorities and shaping a future-proof roadmap, this case provides valuable insights into how circular principles can be embedded in ship design, operations and decommissioning. Presented by Jorn Bertens, Manager Procurement & Supply Chain at Van Oord Ship Management, drawing on extensive experience in shipbuilding and naval architecture.
