Sustainable Ships assisted HEBO gain crucial insights into the cost-effectiveness of different decarbonization measures, in particular battery hybrid solutions and the use of alternative fuels. The project went beyond technical details like engine usage and operational profiles, but also involved close cooperation to develop a tailored strategy to comply with regulatory standards.

Sustainable Ships assisted Forsa with the exploration of multiple decarbonization pathways, in particular with respect to hybridization of a general cargo vessel and the use of biofuels. Additionally a detailed scenario planning for long-term decision making was made, that allowed the shipowner to quickly compare the costs of newbuild vs. refits with respect to several OPEX parameters including regulatory compliance.

Sustainable Ships performed a techno-economic feasibility study for the Province of South-Holland and InnovationQuarter on offshore charging of tankers at the anchorage at Scheveningen. As part of the job, a purpose-build tool for interactive parametric design to create insights for decision-making. The study determined that offshore charging of tankers is technically and economically feasible.

Sustainable Ships supported Van Oord in developing a customized Decarbonizer to enable scenario planning and long-term sustainability decision-making. The tool provides a structured way to assess decarbonization pathways at vessel level, linking technical options with regulatory and strategic considerations.

Sustainable Ships supported Steenstra Shipping with a vessel-specific decarbonisation roadmap for the Douwe-S, providing a structured assessment of regulatory requirements and feasible carbon reduction measures. The work informed long-term decision-making by clarifying compliance implications under EEXI, estimating the cost impact of measures such as shore power, and evaluating opportunities to repurpose existing onboard systems.

This thesis performs a technical, economical and environmental feasibility study of three dense hydrogen carriers as a fuel to power the largest semi-submersible offshore crane vessel in the world – Heerema’s Sleipnir.
