Cape Horn Engineering partners with sustainable shipping initiative EcoClipper

Press Release: Marine technology consultants Cape Horn Engineering announce their involvement with the design of the first EcoClipper ship. As environmental concerns are influencing a greater need for renewable and sustainable energy across the world, specialist technologies are at the forefront of new designs and solutions. The innovative EcoClipper ship concept has been created by a group of visionaries to help reduce global emissions and to create a greener, shipping industry.  




Concentrating on the traditional principles of harnessing the power of wind for ship propulsion, the EcoClipper ship will offer emission-free sustainable transportation for cargo, passengers, and trainees around the world’s oceans.


The Dutch-based company, EcoClipper, was founded in 2018 by Jorne Langelaan, sail cargo expert and co-founder of shipping company Fairtransport. The new EcoClipper fleet of ships will sail on four shipping lines with fixed schedules, thereby creating a new shipping logistics system for sail cargo vessels. 


The EcoClipper500 will be built in steel with modern construction techniques, based on the design of the successful Dutch clipper Noach, launched in 1857. Whilst the original ship was stated as the fastest Dutch sailing vessel ever built, Langelaan, CEO, wanted to test different hull shapes, to ensure the best performance for the sail cargo ship. Langelaan comments:

“The historic records of Fop Smit’s Noach are extensive. As the design of the ship was built around cargo carrying capabilities and passenger comfort. With Cape Horn Engineering’s expertise, we are able to fine-tune the ship to make sure it can sail as fast as possible, whilst retaining these necessities.”

Computational Fluid Dynamics (CFD technology) is a crucial support for naval architects to optimise designs for critical elements such as weight saving, performance predictions, reducing emissions, and ship optimisation. Cape Horn Engineering is a leading consultancy, specialising in CFD and related marine technology solutions.


Cape Horn Engineering’s expertise extends to optimise the design of many composite vessels including racing yachts, sailing yachts, powerboats, superyachts, and renewable energy structures, for clients all over the world. They have been at the core of simulation-based America’s Cup and Ocean Racing design campaigns for over 15 years, always pushing the boundaries. Similarly, they have vast experience in ship hydrodynamics, having been involved in yacht and ship design for the last 2 decades. 


Cape Horn Engineering specialise in high-fidelity RANS based simulation techniques where accurate forces and moments are obtained for the given shape candidates and operating conditions. They use one of the best commercial software packages available, STAR-CCM+ from Siemens PLM and have access to a large high-performance computing cluster.



CFD Design Optimisation


Cape Horn Engineering was chosen by EcoClipper as a partner company to provide the design team with expert CFD analysis for the design of their first hull shape. An ambitious R&D programme was agreed and extensive CFD simulations for 4 different candidate hulls were performed and compared at different sailing conditions to aid the design process.


One of the main challenges was to compare fairly dissimilar hull shape candidates without the aid of a Velocity Prediction Program or VPP, where all hydro and aero forces are balanced. With such a complex sail plan, consisting of three square-rigged masts, maximum of 29 sails (including stunsails), and the maximum sail area being around 1580m2, the generation of a full aerodynamic model was out of the scope of the project. Therefore, sail coefficients for similar sailing vessels found in literature had to be used, to give a relationship between the driving force, side force and heeling moment, to enable accurate calculations to be made for the hydrodynamic performance of the hull candidates. 


Another detailed investigation was aimed at finding the best possible position to install the hydro-generators that will provide the electricity requirements of the vessel. Velocity maps around the hull were analysed in order to find the locations with the most homogeneous and higher speeds for best performance of the turbines. 



Rodrigo, CEO of Cape Horn Engineering, comments:


‘’We are delighted to be involved in this innovative project. We are dedicated to reducing shipping emissions and improving air pollution, and we have a strong desire to contribute to such developments, to help protect our planet. Our investment in researching new technologies is a strong commitment, as we firmly believe the future needs to rely on sustainable energy sources’’.
