Sustainable Ships partnered with Natpower Marine to evaluate shore power integration for a hybrid merchant vessel, analyzing methanol, biofuels, and battery hybrids to assess cost, compliance, and long-term decarbonization benefits.

Sustainable Ships developed an ammonia comparison model in a matter of weeks to showcase the business case of Ammonia vs. LNG to potential shipowners. This tool supports Ten08's plan to build ammonia production infrastructure in the US and help shipowners to decarbonize and comply in the most cost-effective manner with regulations such as FuelEU and EU ETS. ⁠​ 

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 provided the Port of Rotterdam with a techno-economic shore power feasibility study and a custom assessment tool for shipowners. The work estimated conversion costs, identified key technical challenges, and outlined applicable standards and retrofit requirements for connecting vessels to shore power. The study enables shipowners to quickly assess the technical implications and indicative costs of shore power conversion, supporting informed investment and retrofit decisions.

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.
