Sustainable Ships developed a tailored business case tool for Quadrise PLC to quantify the commercial and environmental benefits of MSAR® and bioMSAR™ fuels. The tool enables shipowners to compare fuel costs, emissions reductions, and regulatory exposure under EU ETS, FuelEU Maritime, and IMO Net-Zero. This project demonstrates our ability to translate clean fuel technologies into compelling value propositions through data-driven modelling, regulatory insight, and user-focused design.

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 built three dedicated e-mobility tools for Equans to support sales discussions, investment structuring, and depot-level energy analysis. The tools enable rapid budget estimates, scenario evaluation, and first-stage investment decisions, helping streamline internal workflows and reduce time spent on quotations.

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 provided Damen Shipyards with a tailored report outlining upcoming sustainability regulations and their implications for the Damen vessel portfolio. The analysis covered key frameworks such as EEXI, CII, and EU ETS, included indicative cost assessments, and placed regulatory developments in a broader market context by considering the ambitions of energy majors, ports, and shipping companies. The report is used as a structured basis for long-term sustainability decision-making across Damen’s portfolio.

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.

One of our crew members was a key driver in Heerema’s ambitious decision to make the company Carbon Neutral, compensating 250.000 [mT] of CO2 per year.

One of our crew members realized the largest shore power connection in Rotterdam - 20MW - from inception, to design, up to project management and execution.
