Ontwikkeling prototype eConowind-unit van start

VentiFoil windhulpvoortstuwing voor schepen

Als innovatieve scheepsontwerpers zijn wij altijd op zoek naar nieuwe mogelijkheden die het schip net dat beetje extra geven om zich te kunnen onderscheiden van de rest. Om dit te realiseren  onderzoeken we continu nieuwe mogelijkheden die leiden tot een beter schip. Een van deze onderzoeken is gestart in 2008 en heeft geleid tot de veelbelovende econowind-unit. Samen met het in 2016 opgerichte Econowind wordt nu het eerste prototype gerealiseerd, gesteund door Samenwerkingsverband Noord Nederland (SNN).

Een eConowind-unit bestaat uit een 40-voets container met 2 VentiFoils: vleugelvormige masten van 11 m hoog welke met innovatieve grenslaagafzuiging en ‘flaps’ voor aanvullende windvoortstuwing op schepen op zee kan zorgen. Het brandstofverbruik van de conventionele, fossiele brandstofvoortstuwing en dus de CO2-uitstoot, worden daarmee evenredig gereduceerd. De ontwikkeling van deze innovatieve VentiFoil windvoortstuwing is geïnitieerd door Conoship International BV en ondergebracht in een aparte onderneming eConowind BV, beiden gevestigd te Groningen.

Het gehele project bestaat uit ontwikkeling en testen van een 1:1 prototype van de eConowind-unit met speciale VentiFoil vleugelprofielen, de mechanische constructies (zwenken en inklappen), de besturing voor inklappen en autonoom varen. Voor een 1:2 schaalmodel (resultaat van een voorbereidend onderzoek, voorafgaand aan dit project) worden instellingen (zoals ‘zeilstanden’ in relatie tot windsnelheden) en werkingscondities (luchtafzuigparameters) theoretisch en proefondervindelijk onderzocht en vastgesteld. Met de resultaten van het 1:2 model wordt een 1:1 prototype van de eConowind-unit ontwikkeld. Het prototype wordt na sterkteberekeningen voor de vleugelmast, klapconstructie, behuizing en dekbevestiging ontworpen en gebouwd.

Gemiddelde besparingen van 20 tot 30% op brandstof en CO2-uitstoot zijn te verwachten, met het juiste aantal eConowind-units per schip. Ook de volledig autonome besturing van de VentiFoils, steeds optimaal afgestemd op de actuele windsnelheid en –richting, wordt ontwikkeld en getest op zee. Te onderzoeken en testen veiligheidsaspecten omvatten onder ander de constructie, montage aan boord en automatisch inklappen van de VentiFoils bij zware storm en te grote hellingshoeken van het schip.













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.

Conoship International New Year’s Reception

New concept, Same success!

Conoship New Year’s Reception 2018: New concept, Same success!

Last Friday (January, 12th) the annual Conoship New Year’s Reception took place at MartiniPlaza in Groningen. A new concept of pitches of young start-up companies was with a high turnout of 200 till 250 people a great success!

After the New Year’s speeches of mr. Geert Dokter (managing director of Conoship International) and mr. Bas Ort (chairman of NMT) five start-up companies showed their potential in a 5 minute pitch to present their current ideas and reality about what could be the future of maritime related companies. At the end of this news release you will find a brief desciption of the companies.

For Conoship the reception was a great success, positive comments during and after the reception. Therefore we would like to thank the Netherlands Maritime Technology (NMT) for their cooperation in realising this success.
Futhermore, we would like to wish everybody who was not present at the reception also a prosperous 2018! And keep in mind the quote “We all need our strong competitors the keep us as the Dutch maritime cluster ahead of the rest of the world.”

eConowind is our solution for fuel and CO2 reduction for existing and newbuilt vessels in the near future. A “plug-and-play” removable containerized unit which can deployed on your demand. The first calculation results show a reduction up to 20% of fuel and CO2 with four units.

Keel laying ceremony for six new Lady H-type vessels for Wijnne Barends

Keel laying ceremony at Chowgule and Company for six new Lady H-type vessels

The keel laying ceremony took place in a beautifully decorated hall at the yard in India.

The six new vessels, with a deadweight capacity of about 4,200 tons and a length of 98 metres, are designed to meet the increased environmental requirements that apply to newly built vessels (Tier III standards). The delivery of the first ship has been scheduled for the last quarter of 2018. The vessels will be added to the existing (Lady-H) series in intervals of four months.

The Challenge of Big Data

The Challenge of Big Data, Conoship Internationals New Years reception

The 2017 Conoship New Year’s Event was a big success. Despite the early morning snow and the icy weather, many guests came to Groningen to toast to an exciting 2017.

Through the interesting presentations at our mini-symposium we got a glimpse of what the future might hold for the maritime industry: The Challenge of Big Data.

After Guus van der Bles (Conoship) shared Conoship’s thoughts on a number of subjects, including the potential of Big Data in Ship design, the questions it might raise and how Conoship is innovating and getting ready for the future, four other speakers followed and presented their view on big data from their own field of expertise.

Geert Schouten (Shipbuilder) showed us how big data has already been implemented in ship design and what advantages it can bring us through his program “Shipbuilder.” As an example, using a random GA and the application of augmented reality he showed us only a small part of what big data can mean not only for designers but also for ship-owners and shipyards.

Dan Veen (We4Sea) shared in a very clear presentation how his program uses big data to reduce fuel consumption up to 20% leading to lower emissions and getting grip on CO2 output. All this to save costs and at the same time comply with the latest emission regulations.

Robert Hekkenberg (TU Delft) put forth some interesting questions about autonomous shipping, referring to many commercial and non-commercials initiatives building on this subject. A Dutch Joint Industry Project and a European project concerning Autonomous Shipping are about to start, which should lead to two actual operational demonstrators.

Gijsbert de Jong (Bureau Veritas) presented to us how the class societies are getting ready for the future and how big data could bring all parties in shipbuilding closer together and make classification better and easier as well as part of the whole process of shipbuilding and shipping.

Conoship wants to thank all the guests for their presence and especially the speakers for their inspiring presentations.

We wish you all the best for 2017 and are certain that together we can make the best designs and vessels of the future.

Conoship Research & Consultancy – Risk assessment


Conoship International is renowned for its innovative designs, always exploring the frontiers of technical and regulatory possibilities. In the light of the IMO “Guidelines on Alternative Design and Arrangements”, Conoship has developed an unique service for a design company: Risk Assessment.

We can support our customers through the process of identifying and assessing the risks that may arise from the application of a design innovation.

Being Ship Designers rather than pure safety experts, we will apply our full holistic ship knowledge assessing risks with a much wider scope, taking technical, operational and implementational risk into account together with safety risks, thus contributing to an even better innovative design.

We have successfully organized risk assessments for LNG driven ships and we are eager to apply this method to other innovative designs as well.
