Conoship International New Year’s reception 2019

Innovative ship propulsion and design: paving the road to zero emission shipping.

On the 11th of January 2019, the annual Conoship New Year’s reception took place in MartiniPlaza in Groningen. More than 200 guests attended the successful reception with this year’s theme: Innovative ship propulsion and design: paving the road to zero emission shipping presented in four presentations about different innovations contributing to the reduction of the ecological footprint in shipping.

The four areas of discussion were: Carbon Capture (CO2AST), Wind, Hydrogen and LNG. Further information regarding each one of these projects and their speakers is given below.

Conoship International was excited to host the New Year’s reception 2019 that was supported by Marigreen and in close cooperation with-Mariko, FME and the Netherlands Maritime Technology (NMT). We are thankful that there was such an interest in the innovative topics. We conclude that this year we reached the next level in reducing the ecological footprint in the shipping industry. Conoship International wishes a successful 2019 to everyone that attended the event and to the ones that were not able to come. And do not forget that together we can do more!

The moderator during the event was Bas Ort, Chairman of the NMT, who succeeded in capturing the attention of the audience during the four pitches.

Before the start of all four pitches, Jan Jaap Nieuwenhuis gave an inspiring opening speech about the changes in the world concerning the awareness of the changes in environment starting at the schools of today’s generation. He also thanked MariGreen for the cooperation in organizing this New Year’s reception and on their success in research in GreenShipping technologies. He introduced Ilona Heijen, the new head of INTERREG at the Ems Dollard Region that supports the MariGreen projects. Ilona gave a great speech (in Dutch and German) about the things that she see’s happening when working together with the MariGreen projects as an inspiring example.

The first pitch revolted around the subject of Carbon Capture (CO2AST) and was discussed by Jeanine Klinkenbijl, ZEM Projects. She explained that the project was developed in a joint venture between German, Dutch companies and knowledge institutes. The technology consists of absorbing CO2 and then liquefying and storing it on board. The liquid can then be transshipped in the port and sold to potential end users. This technology would be implemented for the first time worldwide.  The second pitch about WIND was discussed by Michael Vahs, professor at the Hochschule Emden/Leer. He talked about the vessel of the future making use of wind propulsion. The vessel he showed was equipped with one Flettner rotor, one eConowind-unit and a version of wind assisted propulsion that represented a combination of both technologies.

The third pitch about Hydrogen was discussed by Arjen Mintjes, teacher at the Maritieme Academie Harlingen. He shared that after emission limits for CO2, HC and NOx are tightened in the last years, this trend is expected to continue. In order to comply with the new standards, alternative propulsions systems as well as fuels should be considered. From this point of view, hydrogen is very promising, because it allows for a significant reduction of emissions.

And last but not least the pitch about LNG was discussed by Leo van der Burg from FME. He was a great substitute for Guus van der Bles who couldn’t be there in time because he had to be in Rotterdam for the Christening from the Ecodelta, a Conoship International designed trailing suction hopper dredger on LNG. Leo explained that one way to meet stricter environmental requirements in shipping, but also in other segments of the transport and energy supply sector, is the use of natural gas. LNG (Liquified Natural Gas) is natural gas that is brought to a liquid state by cooling to a temperature of about -162 ° C.

After the pitches everyone could visit the stands and get inspired or share their ideas and knowledge. All together it was a great start of the year.

Ecodelta-the new LNG consuming dredger

In 2015, the project Ecodelta was initiated by Van der Kamp, a Zwolle-based dredging company and Conoship International. Ecodelta is a trailing suction hopper dredger which consumes liquified natural gas (LNG). This one of a kind dredger has two main objectives: recover valuable material from the seabed and create a greater depth of water. The vessel has a length over all of 134.10m, the breadth moulded 21.40m, a dredging draught of 7,770m, a hopper volume of 5900m3, a dredging depth below baseline of 35m and a Gross tonnage of 7560 GT. The ship has been designed by Conoship International and has been built by the Frisian shipyard Barkmeijer. Today, January 11th, the vessel will be christened. Conoship International congratulates Van der Kamp with reaching this milestone and thanks them for the pleasant cooperation throughout the project. Conoship International is very proud of the result and wishes the Ecodelta and her crew many safe journeys.


Environmentally friendly

Van der Kamp has signed a contract with the Port of Rotterdam Authority, in order to perform maintenance of port of Rotterdam until 2023. The final goal is to become the most sustainable port by replacing the fuel oil with LNG for shipping. Another advantage of LNG is cost-efficiency. The LNG tank of approximately 300m3, can store an energy which can be used in a period of two weeks.

Ecodelta is already meeting the upcoming regulations for emission reduction that will come in force in 2020. The usage of LNG reduces the emissions of CO2 up to 20% and NOx up to 85%. In addition, Sulfur Oxide is reduced to zero.


CONOSHIP International decreases significantly the ecological footprint of shipping

Conoship International B.V. is in continuous innovation since 1952. The passionate team of Conoship International delivers the next level in ship design by introducing equipment which support the positive human impact on Earth’s ecosystem.

Since 2017, Conoship has been developing the eConowind-unit which is used to reduce emissions and fuel consumption. The unit has two foldable VentiFoils which create a superior thrust. Two, four or six units can be fitted on a vessel. In the case of two eConowind-units on a vessel with 5000 ton cargo, it is expected that the average fuel savings and reduction of emissions will be between 10 to 20%. The first trials of testing at sea have been successful and the results are promising. Therefore, Conoship International makes a big step towards emission free shipping.

Conoship strives to add more value to the development of new as well as future equipment which will decrease the ecological footprint. In this manner, the organization advocates the philosophy of a global citizenship by initiating a forthcoming transition to the usage of more renewable energy systems. As a result, Conoship has launched and is involved in several research projects for alternative fuels. In the next years, Conoship will present designs for a fleet that will be able to fulfil any foreseeable future demands, up to zero-emission.

Innovative general cargo vessel

Methanol as marine fuel

The potential of methanol as alternative marine fuel:                                                                            LeanShips

As member of the LeanShips project Conoship International plays a great role in the research of the possibility to use methanol as a marine fuel.

With its simple molecule, methanol has great potential to become the future marine fuel as it is safe to handle, environmentally friendly and can be produced from a large number of available raw materials from natural gas to biomass.

Conoship International already has a wide experience with assessments for conversions on existing ships but we also developed several new ship designs where the use of methanol as main fuel has a central role. These designs are made for new builds that will be powered with methanol as main fuel from the build or are easy to convert from one type of fuel to another.

Beside the technical part Conoship International has also developed a great Economic Assessment Tool. With this program several combinations of ship types, voyages and used fuel can be analyzed to compare alternative fuel options and to get an optimal prediction of the cost and returns for these scenarios.


Why methanol,

No sulfur and low NOx > near to zero emission.Methanol

Still liquid under ambient circumstances so easy and safe to transport and store.

Dilutes in water so no environmental harm in case of spills.

Already adopted within the provisional rules and regulations of Lloyd’s Register.

Widely available all around the world.

Can be used as fuel for combustion engines and also with a DMFC (Direct Methanol fuel Cell)


Is it Green?

With methanol as a fuel you are in compliance with Tier III regulations without any further aftertreatment.

Methanol has a very small ecologic footprint as it can be produced from a variety of renewable sources.

Methanol readily dissolves in water and biodegrades rapidly.


Conoship International will keep on investing in new designs and knowledge and we are ready to help you with questions about new solutions for your future ship propulsion.

Refit Icebreaker to Superyacht

In the summer of 2017 Conoship’s research and Consultancy department was assigned with the conversion design study for an icebreaker vessel (originally also designed by Conoship International) to a luxurious explorer super yacht. On basis of the owners and Icon Yachts’ wishes and demands we provided a technical general arrangement plan together with a positive advice for the technical feasibility of the refit.

Together with Icon Yachts architects we fit the needs and class of a luxurious explorer yacht into an existent icebreaker/maintenance vessel within current rules and regulations and modern technical demands. Keeping the characteristics of the ship, resulting in a modern yacht like no other.

With the owners and Icon Yachts’ approval we are proud to announce that Conoship Internationals naval architects proceed with the refit of this conversion. Carrying out the basic design including rules and regulations study (large yacht code 3 and polar code), construction, arrangements drawings and HVAC design and integration Conoship International has proven again to be a design and engineering company with great expertise in a wide range of vessels.

Launching new website eConowind

Launching new website eConowind

With the launch of the new website:, eConowind takes another step in the promotion and development of Wind-Assisted Ship Propulsion with the eConowind-unit, for which a 12m full scale prototype is under construction.

The eConowind unit is a product of eConowind: a Dutch based company, daughter of Conoship International and HCP. The development of an economical Wind-Assisted Ship Propulsion-unit that can easily be applied on new and existing vessels was initiated by Conoship. The resulting eConowind-unit is a combined effort with eConowind BV and an important step to realize Conoship International’s vision on a future of emission-free shipping. That goes beyond the IMO 2020 goal to reduce the future fleet CO2 output.

The development of the eConowind-unit is supported by the European Union and the three northern Dutch counties (SNN) with the VIA funding for regional development.

For further details about the eConowind-unit please visit the new website at or visit our presentation on the latest VentiFoil developments in the Natural Propulsion seminar on Wednesday May 30th in the BlueWeek 2018 in STC in Rotterdam.

Research & Development

Conoship International has a strong focus on research & development and the application of R&D-results in innovative ship designs, improving efficiency related to aspects like fuel efficiency, cargo hold, lowest EEDI, CO2 output minimisation and more. We have initiated and are involved in several research projects for alternative fuels, to enable shipping to remain the biggest and one of the greenest players in future transport.

Multiple eConowind-units can be applied on a ship, leading to expected average fuel reductions up to 25%, but this is only a small part of our vision on the fleet of the future. Later this year we will present our designs for a fleet that will be able to fulfil any foreseeable future demands, up to zero-emission.

Conoship International expands office

Conoship International expands their office.

Only six months after the office renovation in 2015, Conoship International expands their office on the fourth floor of the Northern Trade Center building in Groningen. Half of the northern wing, initially meant for engineering projects, was fully occupied for the next eighteen months. Eventually Conoship decided to renew the complete northern wing and expand their office to the full top floor of the building. This expansion resulted in an office space of approx. 800 m2 , with a design department and an engineering department, where the potential is to (re-)arrange this office space by project teams relevant to our projects.
The expansion of the office space is an appropriate action of the continuous growth of Conoship in the last four years to about 40 employees at this moment.

5500m3 TSHD one step closer to delivery

5,500m3 Trailing Suction Hopper Dredger for van der Kamp one step closer to delivery.

The 134 m long dredging vessel, fuelled on LNG left the safe boundaries of the dry dock facilities at Delfzijl and was successfully launched last Friday, March 9th 2018. She safely hit the water and soon she will towed to the port of Harlingen were the complete outfitting will take place. Conoship International wants to congratulate Baggermaatschappij Van der Kamp and all suppliers involved, with this milestone.

Already in 2013 Conoship started with a feasibility study for a TSHD fuelled on LNG for Van der Kamp resulting in a contract early 2016 for a complete basic design and engineering package following the detailed construction engineering, including piping routing. The vessel complies with the IMO tier III rules and regulations set in 2020 and belongs to one of the first dredgers on LNG. After the delivery her working location will be the port of Rotterdam for harbour maintenance, until at least the year 2023.
