The presentation was delivered by co-founder Gianmarco Teso, who introduced the company’s vision for mobile offshore nuclear energy systems designed to support flexible and resilient power generation at sea.

The discussions throughout the event reflected a clear and growing interest in offshore energy systems. Engaging with industry professionals and researchers provided valuable feedback and fresh perspectives, which will contribute to the ongoing refinement of Sea Green Engineering’s concept.

Sea Green Engineering would like to express its sincere gratitude to MARIN for organizing the event, to ENSM (École Nationale Supérieure Maritime) in Marseille for hosting the conference, and to all speakers and participants for the high quality of discussions and contributions throughout the week.

Special thanks are also extended to Claudio Filippone (Filippone and Associates) for his support in providing valuable data supporting the integration of HOLOS reactor technology within the proposed system.

At its core, the concept remains simple: when power becomes mobile, energy access becomes universal.

Our scope includes:

👉 Designing and sizing the sail’s foundation-ship interface and related structural modifications up to detailed engineering level
👉 Updating general arrangements and other ship’s general documentation
👉 Revising stability calculations to ensure a seamless and safe integration of this cutting-edge wind propulsion technology

This collaboration marks another step toward decarbonizing maritime transport and showcases how engineering can enable the transition to a cleaner, more sustainable shipping industry.
This collaboration is not just another step toward decarbonizing maritime transport — it’s a testament to Sea Green Engineering’s proven expertise in Wind Assisted Ship Propulsion (WASP) and in seamlessly integrating cutting-edge green technologies on board. Our deep experience in delivering end-to-end feasibility studies and detailed engineering makes us the ideal partner for shipowners ready to embrace wind propulsion and accelerate their transition to a cleaner, more sustainable fleet.

Last week, Sea Green Engineering participated in a site visit and onboard survey of the ANTE TOPIC bulk carrier at Port Morski Police, Poland, as part of the ongoing activities within the EU-funded GAMMA project.

The survey and technical meetings marked a key milestone in the development of the project, which aims to retrofit a bulk vessel with a next-generation hydrogen-based fuel cell system capable of generating 1 MW of clean electric power.

The innovative system will use green ammonia and biomethanol as primary fuels. These will be converted into hydrogen through ammonia cracking and methanol reforming processes. After purification, the hydrogen will be used to power fuel cells, replacing the vessel’s conventional auxiliary diesel generators.

To further enhance the system’s environmental performance, part of the hydrogen production process will be powered by renewable energy sources, such as solar panels, significantly reducing overall emissions.

Sea Green Engineering is proud to contribute to this ambitious project by providing specialized expertise in structural integration, vessel stability, and seakeeping analysis, supporting the safe and effective deployment of these advanced technologies on board.

We are pleased to play an active role in this important step toward decarbonising maritime transport and demonstrating the feasibility of hydrogen-based auxiliary systems for commercial shipping.

– What Can NEXT Do?

NEXT revolutionizes the preliminary sizing of full electric PPE (Power Propulsion Energy) systems for any type of vessel through a holistic approach. By inputting critical data such as the ship’s hull model, available system volumes, operating profile, and shore-based charging locations, NEXT utilizes an Mixed-Integer Quadratic Programming (MIQP) optimization algorithm to determine the size of the electric motor, the optimal quantity and type of Electric Storage Systems (ESS), and the power specifications for shore charging stations. The on-board auxiliary and energy management systems are optimally designed to minimise costs and maximise energy efficiency in long-term operation.

This ensures that both the electric vessel and the recharge system are technically viable and cost-effective.

– Who Is NEXT For?

Our consulting service, powered by NEXT, is designed for ship operators, ship designers, and ESS manufacturers. We aim to assist in identifying the best solutions for converting existing ships or developing new fully electric units. NEXT enables comprehensive comparisons of different technologies and identifies the most suitable solutions based on specific requirements.

– What Makes NEXT Unique?

NEXT stands out due to its holistic approach, which considers the entire system, including the strong relationship between the ship PPE system and the shore charging infrastructure. This approach allows us to identify solutions that address all aspects and limitations of electrification, including:

– Vessel weight and volume constraints

– The increase in energy demand with the increase of vessel weight

– Ship stability

– Charging infrastructure limitations

– PPE system operation to reduce costs

NEXT ensures that every element is optimized for a seamless and efficient transition to full electric power.

Given the relatively long life cycle of ships, today’s choices for shipowners, shipyards, and designers are difficult to make. What will be the fuels of the next decade, how will energy be stored, managed and distributed on board, what bunkering will be available in most ports?

To answer these questions and to provide our clients with all the tools and solutions to handle the energy transition, Sea Green Engineering offers its service:

“Next PPE System”

A service that Sea Green Engineering has already performed for several clients but now takes a defined form. A process to equip new and existing ships with alternative, low-emission PPE (Power, Propulsion, Energy) systems.

Next PPE System is offered at multiple levels.

Level 1: REQUIREMENTS.

Starting from the operational profile and typical mission of the ship, an analysis is carried out to identify the ship’s energy demand: this will be the basis for the evaluation of possible PPE system configurations.

Level 2: EXPLORATION.

Known ship’s energy demand, its characteristics and the customer’s requirements, a multitude of alternative energy sources (hydrogen, methanol, ammonia, biofuels, LNG, CNG, electricity, …) as well as components to store it on board, convert it into usable energy (internal combustion engines, fuel cells, batteries, supercapacitors, …) and distribute it (hybrid propulsion, electric, …) are screened. A ranking of feasible solutions is then made and the ideal PPE system for the ship is agreed according to the client’s needs.

Level 3: OPTIMIZATION

The next step is the optimization and sizing of the chosen PPE system and the technical-economic evaluation of the developed solution.

Level 4: DESIGN.

The final step involves: for existing ships, the development of the engineering required for the on-board integration of the PPE system and the unit retrofit, and for new construction the complete design.
