Render of LOLO vessel for UPM

Conoship lands contract to design seven vessels

Conoship will work together with Finnish Bore Ltd and Dutch Wijnne Barends, both affiliates of Dutch Spliethoff Group, on the design and build of seven state-of-the-art vessels for sustainable sea transportation for UPM in Europe. The vessels will be ice-strengthened and meet the latest technological, operational and environmental standards. They will be built in China and are scheduled to be delivered in 2021 and in 2022.


Bore Ltd will build three (3) RoLo vessels for transporting UPM’s paper products and Wijnne Barends four (4) LoLo vessels for transporting the company’s pulp and other forest products. Conoship has an intermediate function in this process and needs to translate UPM’s transportation demands combined with the ships’ efficiency into a bankable ship design.  “We need to engineer transportation solutions and design ships with a strong focus on sustainability.” says Geert Dokter, Managing Director, Conoship International. “As we have shown with our concept designs and feasibility studies, we are constantly pushing the borders of innovation. We are very proud to be part of this cooperation, a showcase of future shipping and transportation.”

“The vessels will be fueled with liquid natural gas (LNG) which results in a significant (approximately 25%) reduction of CO2 emissions compared with commonly used marine gas oil. In addition, nitrogen oxides (NOx) and sulphur oxides (SOx) emissions will decrease by approximately 85% and 99%, respectively. The emissions of soot particles will also decrease by 99%,” says Lauri Rikala, Director, Global Break Bulk Shipping, UPM Logistics. All vessels will be chartered by UPM and hence will be fully operated by the company.

“Since the establishment of Spliethoff in 1921, the company has been transporting forest products for our clients – it’s in our DNA”, says Michael van den Heuvel, CCO of Spliethoff. “We are very pleased to be able to offer UPM these next generation sustainable vessels. Minimising our environmental footprint has long been a focal point for the Spliethoff Group and the reduction of emissions is a fundamental part of this. The new vessels running on LNG fit well in our continuous drive for greener operations.”

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, SOx 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.

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.
